Abstract

The present invention relates to compositions comprising alkylamidobetaines obtained from macaubay oil.

Description

[Technical field]

[0001] The present invention relates to amphoteric alkylamido betaine compositions obtained from the oil of the fruit of the macaubay palm. [Background technology]

[0002] Many oil-based products are derived from renewable sources such as oil palm (the main source of palm oil). While such an approach has the advantage of protecting oil reserves, it also has some drawbacks. One challenge is deforestation to plant, for example, oil palm trees, which exacerbates current climate change. Deforestation further leads to unwanted loss of biodiversity and loss of habitat for local tribes. In addition, oil palm in particular requires tropical conditions, with a favorable temperature of about 24-28°C and a minimum of 100 mm / m 2 It requires approximately 100,000 liters of rainfall per month, and approximately 50-70% humidity. These factors limit the possibility of profitable cultivation.

[0003] At the same time, the demand for renewable oils is growing every year due to the increasing global consumption. Products derived from renewable oils can be found in all important industrial sectors, for example food, pharmaceuticals, consumer goods or energy (biodiesel).

[0004] Compounds classified as "amphoteric surfactants" are an important class of surfactants. The best known and most widely used are the so-called alkylamido betaines, especially cocamidopropyl betaine. These betaines are widely used in personal care products such as shampoos, shower gels, and other cleaning products. They are considered to be very mild while having a high foaming capacity. Summary of the Invention [Problem to be solved by the invention]

[0005] However, alkylamidobetaines obtained from coconut oil or coconut kernel oil have certain drawbacks.One of the problematic properties is storage stability, which can be improved.As alkylamidobetaines are basic compounds of care products, they are usually stored, transported and further processed.Therefore, it is desirable to provide alkylamidobetaines with improved storage stability, handling and processing properties.

[0006] Additionally, it would be desirable to provide personal care or cleaning compositions containing alkylamidobetaines that have improved storage stability, application, and performance properties.

[0007] Therefore, there is a need for more environmentally friendly alternatives to alkylamidobetaines derived from renewable oils such as coconut oil or palm kernel oil.Furthermore, there is a need for alkylamidobetaines derived from renewable petroleum resources that exhibit improved storage stability, handling and processability, as well as improved storage stability, application and performance properties in personal care and cleaning products. [Means for solving the problem]

[0008] Therefore, the object of the present invention is to provide an alkylamido betaine composition with improved sustainability profile and improved properties.Furthermore, the object of the present invention is to provide an alkylamido betaine composition whose starting material is obtained from a plant that is less sensitive to temperature fluctuations.Furthermore, the object of the present invention is to provide an amphoteric surfactant with improved sustainability profile and improved properties.Another object of the present invention is to provide an alkylamido betaine composition with improved storage stability and applicable to customized care products.Finally, the object of the present invention is to provide a personal care composition or cleaning composition with improved sustainability profile.

[0009] In this context, a greener alternative would preferably provide at least one, more preferably at least two, even more preferably at least three and especially at least four of the following impacts: reduced water demand, reduced biodiversity loss, reduced habitat loss for local tribes, reduced deforestation, improved restoration of degraded areas and springs and watersheds, improved soil moisture retention, improved resilience to temperature fluctuations and climate change.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Before describing exemplary embodiments of the present invention in detail, definitions that are important for understanding the present invention are provided.

[0027] As used in this specification and the appended claims, the singular forms "a" and "an" also include the respective plural forms, unless the context clearly dictates otherwise. In the context of the present invention, the terms "about" and "approximately" refer to a margin of accuracy that a person skilled in the art would recognize, provided that the technical effect of the feature in question is still ensured. The terms typically indicate a deviation from the indicated numerical value of ±10%, preferably ±8%, more preferably ±5%, and even more preferably ±2%. The terms "comprise" and "comprise" are to be understood as non-limiting. For the purposes of the present invention, the term "consisting of" is considered to be a preferred embodiment of the term "comprising of". Hereinafter, when a group is defined as comprising at least a certain number of embodiments, this means that the group also preferably consists only of these embodiments. Furthermore, the terms "first", "second", "third" or "(a)", "(b)", "(c)", "(d)" and the like herein and in the claims are used to distinguish between similar elements and do not necessarily describe a sequential or chronological order. It is to be understood that terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein can be performed in other orders than those described or illustrated herein. When the terms "first", "second", "third" or "(a)", "(b)", "(c)", "(d)", "i", "ii" and the like refer to steps of a method or use or assay, as described hereinbefore or hereinafter, unless otherwise specified in this application, there is no time or consistency between the steps, i.e., the steps may be performed simultaneously or there may be a time interval of seconds, minutes, hours, days, weeks, months or even years between such steps. It is to be understood that the invention is not limited to the specific methodologies, procedures, reagents, etc. described herein as they may vary.It should also be understood that the terminology used herein is used only for the purpose of describing particular embodiments, and is not intended to limit the scope of the present invention, which will be limited only by the appended claims. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.

[0028] As used herein, the terms "does not comprise", "does not contain" or "free of", in the context that the composition of the invention does not contain a particular compound or group of compounds (which can be combined as collective terms), means that the composition does not contain said compound or group of compounds in an amount greater than 0.8% by weight, based on the total weight of the composition. Further, it is preferred that the composition according to the invention does not contain said compound or group of compounds in an amount greater than 0.5% by weight, and preferably the composition is completely free of said compound or group of compounds.

[0029] When referring to weight percentages of compositions and ingredients contained therein, it should be understood that in accordance with the present invention, the total amount of ingredients does not exceed 100% (± 1% to account for rounding).

[0030] The term "personal care composition" refers to any topical and oral product that can be used by consumers at least once a day as a daily care product for the care, cleaning, protection, maintenance, fragrance, or modification of the appearance or feel of the human body, such as face, hair, skin, or oral care. Personal care compositions may contain one or more active agents, such as organic and / or inorganic UV filters, as well as other ingredients or additives, such as emulsifiers, emollients, viscosity modifiers, stabilizers, preservatives, or fragrances. Suitable daily care compositions are in accordance with the present invention, such as leave-on face and body care products, and rinse-off face, hair, and body care products.

[0031] Suitable rinse-off products are hair shampoos, shower gels, soaps, syndet bars, cleaning pastes, cleaning lotions, scrubs, face washes, intimate hygiene cleaners, bubble bath products, oil bath products, shower bath products, shaving foams, shaving lotions, shaving creams, foam powders / tabs, and dental care products (e.g. toothpaste, mouthwash, etc.) Baby care products such as baby shampoos and bath products are also suitable rinse-off products.

[0032] The term "sunscreen composition" or "sunscreen agent" refers to any topical product that can absorb a certain portion of ultraviolet radiation and also reflect and scatter it. Therefore, it should be understood that the term "sunscreen composition" not only includes sunscreen compositions, but also includes any cosmetic composition that provides protection against ultraviolet radiation. The term "topical product" refers to a product that is applied to the skin, and can refer to, for example, a spray, a lotion, a cream, an oil, a foam, a powder, or a gel. According to the present invention, the sunscreen composition can include one or more active agents, such as organic and inorganic UV filters, and other ingredients or additives, such as emulsifiers, emollients, viscosity modifiers, stabilizers, preservatives, or fragrances.

[0033] Suitable decorative preparations are, for example, lipsticks, nail varnishes, eye shadows, mascaras, dry or wet make-up, blushers, powders, depilatories and suntan lotions.

[0034] Suitable skin care preparations are, for example, moisturizing, refining and lifting preparations. The daily care compositions mentioned can be in the form of a cream, ointment, paste, foam, gel, lotion, powder, make-up, spray, stick or aerosol.

[0035] As used herein, the term "UV filter" or "ultraviolet radiation filter" refers to an organic or inorganic compound that can absorb and also reflect and scatter ultraviolet radiation from sunlight. UV filters can be classified as UV-A, UV-B or broadband filters according to their UV protection curve.

[0036] Generally, UV light can be divided into UV-A radiation (320-400 nm) and UV-B radiation (290-320 nm). The definition of "broadband" protection (also called broad-spectrum or broad protection) is based on the "critical wavelength". To cover the broad band, UV-B and UV-A protection must be provided. According to US requirements, the critical wavelength must be at least 370 nm to achieve broad-spectrum protection. The term "critical wavelength" is defined as the wavelength at which the area under the UV protection curve (protection rate (%) vs. wavelength) is 90% of the total area under the curve in the UV region (290-400 nm). For example, a critical wavelength of 370 nm means that the protection provided by the sunscreen composition is not limited to UV-B wavelengths, i.e., 290-320 nm, but extends up to 370 nm, reaching 90% of the total area under the protection curve in the UV region at 370 nm.

[0037] The term "emollient" relates to certain cosmetic oils used to protect, moisturize and lubricate the skin. The word emollient comes from the Latin "mollire" (to soften). In general, emollients prevent the evaporation of water by forming an occlusive cover on the skin. They can be divided into different groups according to their polarity index.

[0038] "Polarity index" is a term that refers to non-polar or polar oils. Non-polar oils are mainly composed of hydrocarbons and do not contain electronegative elements such as oxygen. In contrast, polar oils contain heteroatoms with different electronegativities, which result in a dipole moment. However, such oils are still water-insoluble, i.e., hydrophobic. The polarity index can be determined by measuring the interfacial tension between each oil and water.

[0039] As used herein, the term "fatty acid" refers to a primary carboxylic acid, straight or branched, preferably straight. Fatty acids may contain from 4 to 26 carbon atoms. According to the present invention, the term fatty acid encompasses saturated and unsaturated acids. The double bonds of unsaturated fatty acids can give either cis or trans isomers. In this context, there are caprylic acid, capric acid, lauric acid, myristic acid, myristoleic acid, palmitic acid, palmitoleic acid, sapienic acid, stearic acid, oleic acid, elaidic acid, vaccenic acid, linoleic acid, linoelaidic acid, α-linolenic acid, arachidic acid, arachidonic acid, eicosapentaenoic acid, erucic acid, behenic acid, docosahexaenoic acid, lignoceric acid, and cerotic acid.

[0040] prefix C n -C m indicates in each case the possible number of carbon atoms in the group.

[0041] As used herein, the term "alkyl" in each instance denotes a straight-chain or branched alkyl group, typically having 1 to 30 carbon atoms, preferably 4 to 26, or 1 to 6, or 1 to 3 carbon atoms. Examples of alkyl groups are methyl, ethyl, n-propyl, isopropyl, n-butyl, 2-butyl, isobutyl, tert-butyl, n-pentyl, 1-methylbutyl, 2-methylbutyl, 3-methylbutyl, 2,2-dimethylpropyl, 1-ethylpropyl, n-hexyl, 1,1-dimethylpropyl, 1,2-dimethylpropyl, 1-methylpentyl, 2-methylpentyl, 3-methylpentyl, 4-methylpentyl, 1,1-dimethylbutyl, 1,2-dimethylbutyl, 1,3-dimethylbutyl, 2,2-dimethylbutyl, 2,3-dimethylbutyl, 3,3-dimethylbutyl, 1-ethylbutyl, 2-ethylbutyl, 1,1,2-trimethylpropyl, 1,2,2-trimethylpropyl, 1-ethyl-1-methylpropyl and 1-ethyl-2-methylpropyl.

[0042] As used herein, the term "alkoxy" denotes a straight or branched alkyl group, in each case bonded via an oxygen atom, usually having 1 to 6 carbon atoms, preferably 1 to 2 carbon atoms, more preferably 1 carbon atom. Examples of alkoxy groups are methoxy, ethoxy, n-propoxy, iso-propoxy, n-butyloxy, 2-butyloxy, iso-butyloxy, tert-butyloxy, etc.

[0043] As used herein, the term "alkylene" refers to a linked straight or branched alkylene group, typically having 1-4 carbon atoms, e.g., 1, 2, 3, or 4 carbon atoms. The alkylene group bridges from a particular group to the remainder of the molecule. Preferred alkylene groups include methylene (CH2), ethylene (CH2CH2), propylene (CH2CH2CH2), and the like. Those skilled in the art will appreciate that when referring to, for example, CH2, where the carbon atom is tetravalent, two valences are left to form a bridge (-CH2-). Similarly, when referring to, for example, CH2CH2, each carbon atom has one valence left to form (-CH2CH2-). Furthermore, when referring to, for example, CH2CH2CH2, each terminal carbon atom has one valence left to form a bridge (-CH2CH2CH2-).

[0044] Furthermore, those skilled in the art will recognize that resonance structures may be possible in the oxidized form. Saturated heterocycles, unless otherwise specified, generally include 3-9 membered rings, preferably 4-8 membered rings or 5-7 membered rings, more preferably 5- or 6-membered rings, containing at least one heteroatom, and including 3-9, preferably 4-8 or 5-7, more preferably 5 or 6 atoms, such as pyrrolidine, tetrahydrothiophene, tetrahydrofuran, piperidine, tetrahydropyran, dioxane, morpholine, or piperazine.

[0045] The term "aryl" or "aromatic carbocycle" preferably includes six-membered aromatic carbocycles based on carbon atoms as ring members. A preferred example is phenyl.

[0046] As used herein, the term "oil palm" refers to a species of palm also known as "Elaeis guineensis", which is the main source of "palm oil".

[0047] As used herein, the term "coconut tree" refers to a member of the palm tree family (Arecaceae), also called Cocos nucifera, which is the main source of "coconut oil".

[0048] As used herein, the term "macauba palm" refers to a species of palm. Representative species are known as "Acrocomia aculeata" (also known as "macaiba", "boicaiuva", "macauva", "coco-de-catarro", "coco-baboso", and "coco-de-espinho"), "Acrocomia hassleri", and "Acrocomia totei". Macauba palms, for example, can grow tall, up to about 15 m. The macauba fruit contains pulp and a stone.

[0049] As used herein, the term "pulp" refers to the inner flesh of the fruit.

[0050] As used herein, the term "kernel" is interchangeable with "seed" or "almond."

[0051] As used herein, the term "cleaning composition" includes household care formulations, industrial care formulations, and institutional care formulations.Household care formulations are typically used by individual consumers, while industrial care formulations are typically used by industry, and institutional care formulations are typically used, for example, in clinics and nursing homes.However, each formulation can also be used in areas other than those intended.Therefore, institutional care formulations can be used by individual consumers or industry, and vice versa.Typically, cleaning compositions are for, for example, laundry, dishwashing, hard surface cleaning, food service and kitchen hygiene, food and beverage processing, commercial laundry, hygiene, institutional cleaning, industrial cleaning, and vehicle and transportation care.

[0052] As used herein, the term "liquid" also encompasses semi-solid states where the viscosity of the fluid is increased (eg, creams, gels, ointments).

[0053] As used herein, the term "crop formulation" includes insecticide formulations, fungicide formulations, and herbicide formulations.

[0054] As used herein, the term "oil yield in tonnes per hectare per year" refers to the oil obtained from the fruit of the plant, for example by extraction, the fruit including the pulp and the kernel. It refers to the oil produced per hectare. It should be understood that the value refers to the oil yield obtained from a monoculture, where the plants are grown under standard conditions that depend on the respective plant and are known to the skilled person. Thus, if the plants are not grown in a monoculture (for example, on a cattle ranch), the respective value of this particular cultivation may be reduced. Typically, the oil yield of oil palm is about 3.8 t / ha / year in tonnes per hectare per year, the oil yield of rapeseed is about 0.8 t / ha / year in tonnes per hectare per year, the oil yield of sunflower is about 0.7 t / ha / year in tonnes per hectare per year, and the oil yield of soybean is about 0.6 t / ha / year in tonnes per hectare per year.

[0055] As used herein, the term "monocultivation" refers to the practice of cultivating one plant at a time, for example, the macauba palm, in one field. In the example of the macauba palm, about 500 to about 600 palms can be planted per hectare. In this context, it is preferable that the minimum distance between the trees is about 3.5 to 4.5 meters. This number varies, for example, depending on the soil. The cultivation of the macauba plant is described below. In the first year, growth is slow, since the main development occurs below the soil. Thus, the plant itself grows about 80 to 100 cm. From the second year onwards, when the plant size reaches about 100 to 150 cm, growth becomes faster and there is an increased development of the aboveground part of the plant. A fully mature plant that provides the alleged oil yield per hectare per year is about 5 to 6 years old.

[0056] The water consumption of the macauba plant is 50% less than that of palm. Macauba plantations can be located in areas with a minimum of 1,200 mm of rainfall per year.

[0057] As used herein, the term "amphoteric" means that the compound contains both acidic and basic sites.

[0058] As used herein, the term "amphoteric surfactant" refers to a class of surfactants.The most well-known and widely used are so-called alkylamido betaines, especially alkylamidopropyl betaines.These betaines are widely used in personal care products such as shampoos, bubble baths, and other cleaning products, because they are considered to have high foaming power while being very mild.

[0059] As used herein, the term "forestry" refers to a land use management system in which trees or shrubs are grown around or among other trees or shrubs or other plants such as crops or pasture. It is understood that in forestry, there can be more than just one additional plant. In the example of the macaubay palm, for example, about 250 to about 360 trees, or about 325 to about 350 trees per hectare can be planted. In this context, suitable crops that can be planted together with the macaubay palm are, by way of example, beans, mandioca, corn, cereals, sunflowers, peanuts, rapeseed, soybeans, and mixtures thereof.

[0060] As used herein, the term "silvopasture" refers to a land use management system in which trees and optionally fodder are planted within livestock grazing land. In the example of macaubay palm, for example, about 275 to about 450 trees, or about 375 to about 400 trees per hectare can be planted.

[0061] One advantage of the present invention is that compositions containing the alkylamido betaines of the present invention exhibit improved storage stability and improved handling and processability.

[0062] Compositions comprising alkylamidobetaines of the present invention have improved storage stability in particular. Improved storage stability is achieved when the composition does not show any visible (e.g., cloudiness, discoloration, phase separation, aggregation) or measurable (e.g., pH, viscosity, active substance content, color value) or perceptible (odor) changes over time. Improved storage stability is preferably achieved when less color formation is observed during storage at high temperatures, such as 40°C or higher. Improved storage stability is also preferably achieved when no cloudiness or phase separation can be observed during storage at low temperatures, such as 15°C or lower, for aqueous compositions. Improved storage stability is even more preferably achieved when the composition solidifies and melts over a well-defined narrow temperature range at low temperature levels (<15°C). The solidification / melting temperature range of the composition can be determined by DSC measurements (differential scanning calorimetry). Improved storage stability is most preferably achieved when the composition remains stable and unchanged for as long as possible. In particular, dry compositions, e.g. powders, comprising the alkylamidobetaines of the present invention have improved storage stability if no aggregation, blocking or clumping is observed during storage at elevated temperatures, such as above 40° C., and / or if the composition has good microbiological stability (no microbial growth), e.g. according to the requirements of Ph.Eur. 5.1.3 or DIN EN ISO 11930.

[0063] Preferably, the composition comprising the alkylamidobetaine of the present invention has improved handling and processability. Improved handling and processability is especially observed when the aqueous composition is free-flowing at room temperature (about 23°C) and / or has a viscosity (e.g., shear-thinning behavior) that allows easy stirring and pumping. Improved handling and processability is also preferably observed when the aqueous composition can be rapidly dissolved in the water phase, ideally without additional heating (at about 23°C). Improved handling and processability is also preferably observed when the time required to prepare a personal care composition using this composition is as short as possible. Thus, most preferably, improved handling and processability is observed when the dry composition (e.g., powder) comprising the alkylamidobetaine of the present invention disintegrates and dissolves easily in water and / or when the dry composition (e.g., powder) is suitable for incorporation into a solid personal care composition, i.e., suitable for extrusion or pelletization processes.

[0064] One of the advantages of the present invention is that personal care compositions comprising the alkylamidobetaines of the present invention exhibit improved viscosity and flow behavior, and / or improved appearance / clarity, and / or improved mildness, and / or improved surface activity and cleaning ability, and / or improved lathering ability, and / or improved care performance.

[0065] What is understood to be advantageous viscosity and flow behavior depends on the intended use and application of the personal care composition. For aqueous personal care compositions comprising the alkylamido betaines of the present invention, such as shower gels and shampoos, a high viscosity in the range of 5000 to 20000 mPas (measured using a Brookfield RV laboratory rheometer at 23°C and 10 rpm, spindle selected depending on viscosity range) is desirable. As is well known, "mPas" means millipascal seconds. Thus, the viscosity and flow behavior of aqueous personal care compositions comprising the alkylamido betaines of the present invention, such as shower gels and shampoos, is preferably improved by a higher viscosity at the same alkylamido betaine concentration (and the same concentration of other ingredients) or a lower alkylamido betaine concentration (and / or a lower concentration of other ingredients) and the same viscosity. Preferably, the viscosity and flow behavior of aqueous personal care compositions comprising the alkylamido betaines of the present invention, such as shower gels and shampoos, is improved if the viscosity is not or is not easily affected by temperature (e.g., the viscosity is not or is not easily decreased at high temperatures, such as 40°C or higher). Finally, and preferably, the viscosity and flow behavior of aqueous personal care compositions comprising the alkylamidobetaines of the present invention, such as shower gels and shampoos, is improved if the viscosity is unaffected or less affected by the addition of perfume (e.g., there is no or little decrease in viscosity) and / or if the composition has shear thinning flow behavior, meaning that the viscosity decreases when shear stress is applied to the composition (e.g., when the composition is moved, stirred, pumped, shaken) and / or if the composition has a high viscosity at rest (in a bottle / package, when collected in the palm of the hand) and a low viscosity under shear stress (e.g., when dosed, squeezed out of the bottle, or distributed / applied and rubbed between the hands and / or hair).

[0066] For aqueous personal care compositions comprising the alkylamidobetaines of the present invention, such as pump foams, sprays, micellar waters, or makeup removers, a very low viscosity of less than 200 mPas is desirable, in which case it is advantageous to achieve a lower viscosity with the same concentration of alkylamidobetaine (and with the same concentrations of other ingredients), or to achieve the same viscosity with a higher concentration of alkylamidobetaine (and / or with a higher concentration of other ingredients).

[0067] The aqueous personal care composition comprising the alkylamidobetaine of the present invention is very often required to be transparent, especially when transparent packaging is used.Therefore, it is preferred that the care composition of the present invention has improved transparency.Transparency can be quantitatively determined by transmittance measurement with TurbiScan MA2000 (Formulaction measuring instrument) at 23°C.Preferably, the care composition of the present invention has an average transmittance of at least 80%, even more preferably at least 85%, and most preferably at least 88%.

[0068] For personal care compositions containing the alkylamidobetaines of the present invention, it is desirable to have good compatibility with the skin and mucous membranes (eyes and mouth), and therefore low potential irritation, also called hypoallergenicity. Personal care compositions containing the alkylamidobetaines of the present invention have improved hypoallergenicity. Potential irritation can be determined by methods known to those skilled in the art, such as in vitro methods such as RBC, HET-CAM, or tests on model tissues (epi-ocular / epi-oral), and also by subjects (e.g., skin patch tests, "tear-free" tests by panelists).

[0069] For personal care compositions containing the alkylamidobetaines of the present invention, it is also advantageous to have improved surface activity. Improved surface activity is characterized by either a lower CMC (critical micelle concentration), a lower surface tension, or the ability to reduce surface tension faster than compositions containing alkylamidobetaines obtained from other oil sources. The surface can be, for example, the interface between an aqueous composition and air, gas, or oil. Thus, personal care compositions containing the alkylamidobetaines of the present invention preferably have improved surface activity. Surface activity can be measured by CMC measurement with a tensiometer (DCAT, DataPhysics Instruments GmbH or equivalent), dynamic surface tension measurement by bubble pressure method (SITA-Online T60, Sita Messtechnik GmbH or equivalent). These properties are also relevant to determine the cleaning, dispersing, emulsifying, and solubilizing ability of the composition, in particular for removing dirt and oily substances from hair, skin, hard surfaces, and textiles.

[0070] In parallel with compositions comprising the alkylamido betaines of the present invention, personal care compositions comprising the alkylamido betaines of the present invention also exhibit improved storage stability, as defined above.

[0071] It is desirable for the personal care composition comprising the alkylamidobetaine of the present invention to have good foaming ability.In particular, it is desirable for the composition to be able to generate a foam with a high initial foam volume when the composition is used, for example by rubbing between hands, skin, and / or hair, and / or be stable after foam formation is complete, thus exhibiting no or less volume loss compared to the initial foam volume, and / or no or less drainage (no or little accumulation of liquid under the foam), and / or have small foam bubbles, a narrow foam bubble size distribution, and / or have a high water content (amount of liquid in the foam / total amount of foam), and / or have high elasticity, and / or have a pleasant foam sensation, such as a soft and rich feel of the foam, creaminess, elasticity, moldability, and overall acceptance by consumers. Preferably, foams obtained from personal care compositions comprising the alkylamidobetaines of the present invention exhibit the above-mentioned properties even under harsh conditions, such as in hard water (e.g., 15° dH), at low temperatures, under acidic or alkaline conditions, under high oil loadings, under high salt loadings, and in the absence of anionic sulfate surfactants.

[0072] The foaming behavior of an aqueous composition (or a dry composition dissolved in water) can be investigated, for example, by stirring, shaking, pumping, foaming through a gas stream or otherwise agitating the solution within a short period of time (approximately 10-200 seconds) and then monitoring the foam volume over time (up to 30 minutes) and taking pictures of the foam structure for image analysis. For this purpose, testing equipment such as Foam Expert (SITA Messtechnik GmbH) or Dynamic Foam Analyzer DFA 100 (Kruess) can be used. In addition, foams can be evaluated by rheological measurements in a viscometer.

[0073] Preferably, personal care compositions containing alkylamidobetaines derived from macauba oil leave a gentler feel on hair and / or skin after application than compositions containing alkylamidobetaines derived from other oil sources. This can be investigated, for example, by a test panel, with reference to subjective skin feel (smoothness, dryness, etc.) or the touch and feel of treated hair. Mechanical measurement methods such as hair combing or hair breakage can also be used.

[0074] Preferred embodiments relating to compositions comprising alkylamidobetaines obtained from macaubay oil or that can be obtained by a process comprising the steps of amidation and reaction with chloroacetic acid, as well as their use for the production of alkylamidobetaines, their use as surfactants in personal care compositions and / or cleaning compositions, and these personal care and cleaning compositions themselves are described below. It should be understood that the preferred embodiments of the present invention are preferred alone or in combination with each other.

[0075] A particular advantage of the process of the present invention is that it is more efficient, less energy consuming and therefore more sustainable. The reason is that macauba oil has a lower melting point than, for example, the commonly used palm kernel oil. Therefore, it has a lower viscosity at comparable temperatures and can therefore be processed at lower temperatures with less energy consumption. Another reason is that the sustainability of macauba oil is higher than that of oils from other sources such as coconut oil, palm oil or palm kernel oil, due to its cultivation conditions that consume less water, require less space, are more productive and are more robust enough to be cultivated in less specialized conditions.

[0076] As noted above, the present invention relates in one embodiment to a composition comprising an alkylamidobetaine derived from macaubay oil.

[0077] Preferably, the macaubay oil is obtained by extraction of the macaubay fruit, palm pulp and / or palm kernel. In a preferred embodiment, the macaubay is Acrocomia hassleri, Acrocomia totei and / or Acrocomia aculeata, in particular Acrocomia aculeata.

It is therefore preferred that the macaubay palm is not susceptible to temperature fluctuations.

[0084] As used herein, the term "well grown" means that the claimed oil yield is achievable under standard cultivation conditions.

[0085] In addition, oil palm in particular requires tropical conditions, with a preferred temperature of around 24-28°C and monthly rainfall of at least 100mm / m. 2 , humidity is about 50-70%. These factors limit the possibility of profitable cultivation.

Methods for the preparation of such compounds can be found, for example, in DE-A-2926479A, DE-A-4340423C1, DE-A-4207386C1 and DE-A-4430084A1, respectively. Generally, the reaction can be started directly from the oil source, i.e. by amidation of the glycerides of macaubay oil, or from the fatty acid composition obtained from said oil, i.e. by amidation of the free fatty acids.

[0135] When betaine is prepared from a fatty acid composition, the preparation method further comprises the aforementioned conversion step of preparing the fatty acid composition from macaubay oil. In a preferred embodiment, the conversion step is carried out under chemical or enzymatic conditions, preferably under chemical conditions.

[0136] In a preferred embodiment, the conversion step involves hydrolysis. Any suitable hydrolysis method can be carried out. In a preferred embodiment, the hydrolysis is preferably carried out under chemical conditions, preferably in the presence of a catalyst. In another embodiment, the hydrolysis is preferably carried out under enzymatic conditions, preferably at a temperature of 32-40°C.

[0137] The converting step may further include partial or complete hydrogenation, in which the double bonds of the fatty acid moieties are completely or partially removed. When the converting step includes complete hydrogenation, the fatty acid composition does not include unsaturated moieties.

[0138] Glycerol can be obtained as a by-product of the hydrolysis, preferably after a purification step. In a preferred embodiment, the conversion step further comprises a step of separating out glycerol.

[0139] Thus, the process for the preparation of a composition comprising an amidoalkyl betaine of the present invention comprises: a) reacting macaubay oil or a fatty acid composition obtained therefrom with 3-dimethylaminopropylamine to obtain an intermediate; b) reacting the intermediate with chloroacetic acid or sodium monochloroacetate to obtain an alkylamidobetaine.

[0140] Thus, the preparation is preferably carried out in a two-stage process: in the first step, the macaubay oil or the fatty acid composition obtained therefrom is reacted with dimethylaminopropylamine to obtain the amidoamine, i.e. the intermediate. The reaction is carried out at a temperature ranging from 140° C. to 210° C. and takes from 2 to 6 hours, preferably 4 hours. The amidoamine obtained is preferably washed to remove any excess of residual amine, or vacuum distilled, preferably at a temperature ranging from 130° C. to 170° C.

[0141] In the second step, the resulting amidoamine is reacted with a quaternizing compound, preferably chloroacetic acid or sodium monochloroacetate, more preferably sodium monochloroacetate. This reaction can be understood as a quaternization reaction of tertiary amines using monochloroacetic acid as an alkylating agent. Preferably, a high conversion rate can be achieved using monochloroacetic acid. This is considered to be preferable, since free acid may slightly interfere with the amine function.

[0142] Therefore, preferably, weakly alkaline conditions similar to the degree of dissociation of monochloroacetic acid are preferred. Also, preferably, a slight excess of monochloroacetic acid is used to increase the yield. The reaction is preferably carried out in an aqueous solution. Preferably, the amide of the first step is added at a temperature in the range of 70-90°C, preferably 80-85°C. The temperature is then maintained for 2-6 hours, preferably 3 hours. During the reaction, it is preferable to add a corresponding amount of NaOH every hour to maintain the pH value of the solution. This limits the number and amount of undesired by-products. During the reaction, the pH value is preferably maintained at a value of 8-9.

[0143] The present invention therefore relates to a composition comprising an alkylamidobetaine obtainable by the process described above.

[0144] The composition containing alkylamidobetaine that can be obtained by the above process is an aqueous composition, preferably having a water content of 30-60% by weight and a pH of about 4.5-6.5.

Alternatively, however, the personal care composition can be processed into a powder by drying. Such powders preferably have a moisture content of less than 10% by weight, more preferably less than 5% by weight.

[0155] Preferably, amphoteric surfactants are used to improve viscosity, improve mildness, improve dispersibility, emulsification and / or solubilization, improve stability, appearance and / or feel, and / or improve foaming behavior.

[0163] Preferred embodiments regarding the use of the above outlined compositions as amphoteric surfactants in personal care or cleaning compositions have already been outlined above and also apply to personal care or cleaning compositions.

[0164] Experimental section The present invention is further illustrated by the following examples.

[0165] Measurement method: a) Viscosity The viscosity of the betaine containing compositions, as well as the shampoo and body wash formulations, was measured using a Brookfield JAC-ML-LAB rotational viscometer according to ASTM D2196.

[0166] b) color The color of the compositions containing betaine, as well as the shampoo and soap formulations, was measured with a Lovibond colorimeter using the Gardener color scale (ASTM D1544 and ASTM D1209) and the Lovibond RYBN color scale (AOCS Dd-5-92).

[0167] c) Foaming power 200 ml of a 1% solution of surfactant in a 1000 ml beaker is stirred according to the conditions of the method (see below). The foam formed is assessed in volume immediately after stirring (time zero) and after standing for 5 and 15 minutes.

[0168] 2 g of sample is weighed into a 1000 ml beaker and dissolved in 200 ml of distilled water. The solution is stirred 30 times with a stir bar, moving it from top to bottom through the space of the beaker. Then, a first reading is taken: the top height of the foam (in ml) minus the bottom height of the foam (the reading at time zero (0)). This reading is repeated after waiting periods of 5 and 15 minutes. EXAMPLES

[0169] The following example assumes that Macaubay palm (eg, registration number AEB402A) has an oil yield in tonnes per hectare per year of approximately 9.0 t / ha / year.

[0170] Example IE1 of the present invention Macauba palm, for example, is planted on ranches with about 380 trees per hectare. Macauba palm is cultivated on already existing fields (sylvan pastures), so there is no need to cut forests and farmers can market the macauba fruit in addition to livestock and / or milk production.

[0171] Example IE2 of the present invention Macaubay palm is planted in soybean plantations (height of about 20-80 cm, oil yield of about 0.6 tonnes per hectare per year) with, for example, about 340 trees per hectare. Macaubay palm is cultivated in already existing plantations (agroforestry), so again no deforestation is necessary. Macaubay palm grows to a height of about 15 meters, so soybeans can be cultivated in parallel. In this context, at least one other plant (height of about 1-7 m) can also be cultivated in parallel, such as sunflower (oil yield of about 0.7 tonnes per hectare per year) or beans.

[0172] As can be seen from the above examples, the cultivation of macaubay palm can reduce deforestation considerably. Furthermore, biodiversity can be increased. In addition, even if macaubay palm is not grown as a monoculture, the total oil yield can be equivalent to that of oil palm (with an oil yield of about 3.8 t / ha / year in tonnes per hectare per year) monoculture, since macaubay palm has a higher oil yield as defined above. Without being bound by any theory, degraded areas and springs and watersheds can be more easily restored by using plants with improved oil yields. Furthermore, soil moisture retention is improved.

[0173] Comparative Example CE1 - Preparation of Cocamidyl Betaine from Palm Kernel Oil (PKO) The preparation is preferably carried out in a two-stage process: in the first step, the PKO is reacted with dimethylaminopropylamine. The reaction takes place in a temperature range from 140 ° C to 210 ° C and takes about 4 hours. The resulting amidoamine is washed to remove all excess amine. In the second step, the amidoamine of the PKO is reacted with a quaternizing compound, preferably sodium monochloroacetate. This reaction can be understood as a quaternization reaction of a tertiary amine using monochloroacetic acid as an alkylating agent. High conversion rates are obtained when salts with monochloroacetic acid are formed during the alkylation process, since the free acid interferes with the amine function. Therefore, weakly alkaline conditions are recommended, which are similar to the degree of dissociation of monochloroacetic acid. Also, a slight excess of monochloroacetic acid increases the yield. The reaction is carried out in an aqueous solution, and the amidoamine of the PKO in the first step is added at 80-85 ° C. The temperature is then maintained at 80-85 ° C for 3 hours. During the reaction, it is preferable to add the corresponding amount of NaOH every hour. This limits the number and amount of undesirable by-products. The pH during the reaction should be maintained at a value between 8 and 9. The final product is obtained with a betaine concentration of 20% up to 50% by weight. The sterol content of the final product is up to 1000 ppm.

[0174] Inventive Example IE3 - Preparation of Cocamidyl Betaine from Macaubayi Oil (MAC) Betaine is prepared according to the method provided in CE1, except that MAC was used instead of PKO.

[0175] Comparative Example: Stability of betaine obtained from CE2-PKO Three batches of product prepared according to CE1 were stored for three months in a) a freezer at 5°C, b) room temperature (21°C), and c) a stove at 50°C. Storage in a), b), and c) ensured that no light reached the batches during the stability testing. After three months, the batches were removed, the pH was measured, and the color was determined. The respective values ​​can be seen in Table 1 and a comparison of the colors in Figure 1.

[0176] Stability of betaine obtained from the present invention's example IE4-MAC The method of CE2 was used, except that betaine derived from MAC was used instead of betaine derived from PKO.

[0177] Viscosity, foam, and stability of shampoo obtained from comparative example CE3-PKO The shampoo is prepared by homogenizing phase A according to the amounts shown in Table 1. The ingredients of phase B are then added in order to the homogenized phase A, homogenizing the resulting phase between each addition. Kathon CG is then added and the phase is homogenized. Finally, sodium chloride is slowly added, ensuring that the viscosity of the phase increases. Finally, the pH value is corrected to 5.0-6.5.

[0178] Viscosity, foam and stability of shampoo obtained from inventive example IE5-MAC The method of CE3 was used, except that MAC-derived betaine was used instead of PKO-derived betaine.

[0179] [Table 1]

[0180] Viscosity, foam, and stability of body wash from Comparative Example CE4-PKO The body wash is prepared by adding Texapon® HBN and the product of Example 3 in order to water according to the amounts shown in Table 2, homogenizing after each addition. Then Kathon CG is added and the phase is homogenized. Finally, sodium chloride is added slowly, which increases the viscosity. The pH value is corrected to 5.0-6.5. The viscosity, foaming and stability of the resulting product are measured.

[0181] Viscosity, foam and stability of body wash obtained from inventive example IE6-PKO Prepare the body wash by adding Texapon® HBN and the product of Example 3 in order to water according to the amounts shown in Table 2, homogenizing after each addition. Then add Kathon CG and homogenize the phase. Finally, add sodium chloride slowly, which increases the viscosity. Correct the pH value to 5.0-6.5.

[0182] [Table 2]

[0183] Discussion of results A comparison of the data obtained with CE2 and IE4 is summarized in Table 3. From these data, it can be seen that in the case of betaine obtained from macaubay palm oil (IE4), the pH value after storage for more than 3 months remains constant, regardless of the temperature during storage, compared to betaine obtained from palm kernel oil. Furthermore, it can be seen that betaine obtained from macaubay palm oil is less likely to become discolored during storage, as shown by the color photograph in Figure 1. Thus, in summary, betaine obtained from macaubay palm oil shows a good stability during storage, especially a stability independent of the temperature during storage, compared to betaine obtained from palm kernel oil.

[0184] [Table 3]

[0185] A comparison of the data obtained with CE3, CE4, IE5 and IE6 is summarized in Table 4. From these data it can be concluded that the viscosity of shampoos and / or body washes obtained from macauba oil is at a comparable level compared to that obtained from palm kernel oil. Moreover, it can be seen that this property is achieved with an acceptable and consistent stability of the composition during storage. Finally, shampoos and soaps obtained from macauba oil show improved foaming.

[0186] [Table 4]

[0187] The resulting shampoo and body wash colors after storage are shown in Figure 2. In parallel with the results of the pure betaine compositions, the shampoo and body wash derived from PKO also showed higher yellow color intensity compared to the shampoo and body wash derived from MAC, further demonstrating the improved storage stability of shampoo and body wash compositions containing MKO-based betaines.
