Description

[0001] Solid granular material for the preparation of personal care products

[0002] Field of the invention

[0003] The presently claimed invention relates to a solid granular material for use in the preparation of a personal care product. Further, the presently claimed invention relates to a method for preparing the solid granular material. The invention also relates to a kit-in-part comprising the solid granular material.

[0004] Background of the invention

[0005] Personal care products such as sunscreens, shampoos, conditioners, and shower gels are ubiquitous parts of modern life. The requirements for these personal care products are constantly increasing regarding performance, sustainability, and cost. Long shelf-lives are also necessary for personal care products since they are often used for weeks to months; some of them being used mainly in particular seasons of the year such as sunscreen products or only in irregular intervals. At the same time, many preservatives used in personal care products to increase the shelf-life are suspected to cause allergic reactions at least with some consumers, so that there is a growing demand for personal care products with only low quantities of preservatives as well as for personal care products that are completely free of preservatives.

[0006] Another problem related to the stability of personal care products is that some active ingredients in personal care products are water-sensitive, or photo- or thermo-sensitive when in solution. Due to this limitation, such active ingredients can only be used in sub- optimal quantities or must be excluded from the composition entirely.

[0007] There have been some publications in the art that try to solve at least some of the problems outlined above by providing solid cosmetic base materials that can be used to prepare specific types of personal care products on demand.

[0008] EP 0 006 741 A2 describes a self-emulsifying cosmetic base for use in the manufacture of cosmetic compositions in the form of oil-in-water emulsions. The cosmetic base is provided in solid form having self-emulsifying properties. The system in EP 0 006 741 A2 has the disadvantage that the base and the remaining components must be heated to obtain the personal care product. In the Examples of EP 0 006 741 A2, temperatures of at least 60 ° C are necessary for this step.

[0009] EP 0 754 448 Al describes a composition in form a homogenate powder which is selfemulsifying in water. The powder is obtained from aqueous plant extracts. The powder in EP 0 754 448 Al can have the disadvantage of dusting and the preparation method starting from aqueous plant extracts is not well suited for water-sensitive components.

[0010] JP 2005343844 A describes a self-emulsifying oily solid composition comprising 8 to 30 mass% of a component A being a polyglycerol fatty acid ester and 30 to 92 mass% of a component B being an oil component. However, the high oil content in the solid composition of JP 2005343844 A makes it only suited for a limited range of applications, such as for use in cleansing cosmetics.

[0011] There remains an ongoing need to develop a material that overcomes the disadvantages of the prior art and provides low-cost, sustainable personal care products with a long shelf-life.

[0012] Objective of the invention

[0013] Therefore, it was the objective of the present invention to provide a material that results in a low-cost, sustainable, high-performance personal care product with a long shelf-life. Another objective of the present invention was to allow for the use of water-sensitive materials in personal care products. A further objective was to provide a method to access emulsion-type personal care products that fulfill these requirements. Another objective was to provide a method to access leave-on personal care products that fulfill these requirements.

[0014] Summary of the invention

[0015] Some or all these objectives are solved with the aspects of the present invention.

[0016] In a first aspect, the invention relates to a solid granular material for use in the preparation of a personal care product characterized in that the solid granular material comprises

It is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein. In case the terms "first", "second", "third" or "(a)", "(b)", "(c)", "(d)", "i", "ii" etc. relate to steps of a method or use or assay there is no time or time interval coherence between the steps, i.e. the steps may be carried out simultaneously or there may be time intervals of seconds, minutes, hours, days, weeks, months or even years between such steps, unless otherwise indicated in the application as set forth herein above or below. It is to be understood that this invention is not limited to the particular methodology, protocols, reagents etc. described herein as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention that will be limited only by the appended claims. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art.

[0027] As used herein the term “does not comprise” or “free of” herein means - unless otherwise specified - that the composition of the present invention is free of a specific compound or group of compounds, which may be combined under a collective term, that the composition does not comprise said compound or group of compounds in an amount of more than 0.1 % by weight, based on the total weight of the composition. Furthermore, it is preferred that the composition according to the present invention does not comprise said compounds or group of compounds in an amount of more than 0.05 % by weight, based on the total weight of the composition. Most preferred the composition does not comprise said compounds or group of compounds in an analytically measurable amount.

[0028] When referring to compositions and the weight percent of the therein comprised ingredients it is to be understood that according to the present invention the overall amount of ingredients does not exceed 100% (± 1% due to rounding).

[0029] The term “cosmetic composition” refers to any topical product which is intended to be applied to the human body for cleansing, beautifying, promoting attractiveness, altering the appearance, or protecting the skin without affecting the body’s structure or function. Possible cosmetic compositions within the meaning of the invention comprise leave-on and rinse-off products such as face and body care including daily care compositions with or without UV protection and sunscreen or sunscreen compositions, hair care products such as shampoos, conditioners, shower gels, make-up compositions and similar compositions.

[0030] The term “sunscreen composition” or “sunscreen” refers to any topical product which absorbs and which may further reflect and scatter certain parts of UV radiation. Thus, the term “sunscreen composition” is to be understood as not only including sunscreen compositions, but also any cosmetic compositions that provide UV protection. The term “topical product” refers to a product that is applied to the skin and can refer, e.g., to sprays, lotions, creams, oils, foams, powders, or gels. According to the present invention the sunscreen composition may comprise one or more active agents, e.g., organic and inorganic UV filters, as well as other ingredients or additives, e.g., emulsifiers, emollients, viscosity regulators, stabilizers, preservatives, or fragrances.

[0031] The term “daily care composition” refers to any topical product which is intended to be used daily without or with a UV protection. In case UV protection is included, it absorbs and may further reflect and scatter certain parts of UV radiation and is used as an everyday care product for the human body, e.g. for face or body. The daily care composition may comprise one or more active agents, e.g., organic and / or inorganic UV filters, as well as other ingredients or additives, e.g., emulsifiers, emollients, viscosity regulators, stabilizers, preservatives, or fragrances. Suitable daily care composition are according to the present invention, e.g. leave-on face and body care products.

[0032] Suitable leave-on products for face and body are, e.g. sunscreen preparations and skin care preparations.

[0033] Suitable skin care preparations are e.g., moisturizing, anti-ageing, refining, and lifting preparations. The cited leave-on compositions can be in the form of creams, ointments, pastes, foams, gels, lotions, powders, make-ups, sprays, sticks or aerosols. Daily-care compositions with UV protection protect against damages on human skin by UV light.

[0034] The term “UV filter” or “ultraviolet filter” as used herein refers to organic or inorganic compounds, which can absorb and may further reflect and scatter UV radiation caused by sunlight. UV-filter can be classified based on their UV absorbance profile as UV-A, UV-B, or broadband filters. Preferably, the term “UV filter” comprises or consists of any UV filter as defined in the Annex VI (version of 11.11.2022) of the Regulation (EC) No 1223 / 2009 of the European Parliament and of the Council.

[0035] Water soluble UV filters have a solubility in water of at least 2.0 % by weight, preferably at least 3.0 % by weight, more preferably at least 5.0 % by weight.

[0036] Oil soluble filters have a solubility in specific emollients of at least 2.0 % by weight, preferably at least 3.0 % by weight, more preferably at least 5.0 % by weight.

[0037] The term “sensitive skin” refers to skin of which the natural barrier function is weakened and has broken due to a trigger. A trigger can be for example cold weather, extremely hot water and critical ingredients, which may be included in sunscreen or daily care compositions.

[0038] The term “sun protection factor (SPF)” as used herein indicates how well the skin is protected by a sunscreen composition mainly from UV-B radiation. The SPF can be measured in vivo using an application amount of 2 mg / cm2 (ISO 24444, in particular ISO 24444:2019) or in vitro using for example transmittance measurements through a UV transparent substrate or in silico, for example using the BASF sunscreen simulator (https: / / sunscreensimulator.basf.com / Sunscreen Simulator / login). The calculation method for the SPF is also described in the model published by B. Herzog et al. in Simulation of sunscreen performance, Pure Appt. Chem. 2015; 87(9-10):937-951. The sun protection factor indicates how much longer the protected skin may be exposed to the sun without getting a sunburn in comparison to untreated skin. For example, if a sunscreen composition with an SPF of 15 is evenly applied to the skin of a person usually getting a sunburn after 10 minutes in the sun, the sunscreen allows the skilled person to stay in the sun 15 times longer, therefore for 150 minutes. In other words, SPF 15 means that 1 / 15 of the burning UV radiation will reach the skin, assuming sunscreen is applied evenly at a thick dosage of 2 milligrams per square centimeter (mg / cm2).

[0039] The definition of “broadband” protection (also referred to as broad-spectrum or broad protection) may be based for example on the “critical wavelength” or the UVA-PF. For broadband coverage, UV-B and UV-A protection must be provided. According to the US requirements, a critical wavelength of at least 370 nm is required for achieving broad spectrum protection. Furthermore, it is recommended by the European Commission that all sunscreens or cosmetic compositions should have an UV-A protection factor (ISO 24443, in particular ISO 24443:2021), which is at least one third of the labelled sun protection factor (SPF), e.g. if the sunscreen composition has an SPF of 30 the UVA protection factor has to be at least 10.

[0040] The term “critical wavelength” is defined as the wavelength at which the area under the UV protection curve (% protection versus wavelength) represents 90 % of the total area under the curve in the UV region (290-400 nm). For example, a critical wavelength of 370 nm indicates that the protection of the sunscreen composition is not limited to the wavelengths of UV-B, i.e. wavelengths from 290-320 nm, but extends to 370 nm in such a way that 90 % of the total area under the protective curve in the UV region are reached at minimum at 370 nm.

[0041] The term “administration” refers to the application of a sunscreen or daily care composition to the skin of a person.

[0042] The term “solid granular material” as used herein refers to a material made up of a collection of discrete solid and macroscopic particles. Solid granular materials have particular physical properties. The solid, macroscopic particles are surrounded by a gas or a liquid. Due to the size of the solid granular material, the ratio of the volume of the solid to the fluid phase (liquid or gas) is high, meaning that the macroscopic particles are in close contact with one another. Solid granular materials share properties typical for solids and liquids: granular materials can withstand deformation and form heaps like solids while also flowing like liquids and exhibiting compressibility such as fluids in general. Solid granular materials are meta-stable in that they are in a static solid-like state as ground state but can flow like fluid when an energy source is provided. All motions of granular materials require an external source of energy to overcome the loss of energy in the particle interactions. The term “liquid additive” as used herein refers to a volatile or non-volatile chemical liquid substance that introduces or improves certain properties to / of the solid granular material. The liquid additive may be introduced before or during the manufacturing process of the solid granular material. The term “liquid additive” in accordance with the invention comprises or preferably consists of substances of the group selected from humectant, emollient, granulation liquid, and mixtures thereof.

[0043] The term “humectant” as used herein refers to a compound that promotes the attraction and retention of moisture. The term humectant is used herein in its common meaning in the art.

[0044] The term “granulation liquid” as used herein refers to a volatile or non-volatile liquid added to amend the shape, size, surface area and / or density of powders in order to improve their physicochemical properties and handling. The granulation liquid facilitates the wetting and the agglomeration of the blend in the preparation of the solid granular material. In this manner, the granulation liquid provides the blend with optimal properties for the formation of a granular material.

[0045] The term “emollient” as used herein refers to a compound that softens the skin and provides a protective barrier that prevents dryness. The term emollient is used herein in its common meaning in the art.

[0046] The term “carrier” as used herein refers to a compound that provides a general structure to the solid granular material. The carrier holds the other components of the solid granular material together without reacting with them or external components. The terms “carrier”, “carrier material” and “matrix material” are used interchangeably herein.

[0047] The term “surfactant” as used herein refers to surface active agents that decrease the surface tension or the interfacial tension between two phases, e.g. two liquids, a gas and a liquid or a liquid and a solid. Herein, surfactants (also: surface-active agents) are amphiphilic molecules which comprise a nonpolar, hydrophobic portion (typically a straight or branched hydrocarbon chain containing between eight and 26 carbon atoms) which is attached to a polar hydrophilic portion. The hydrophilic portion can be nonionic, ionic, or zwitterionic, and may be accompanied by counterions in case of the ionic or zwitterionic portion. A typical mode of action of a surfactant is that the surfactant molecule orients itself at the interface between two phases with the hydrophobic portion oriented towards the hydrophobic phase (e,g, air / oil) and the hydrophilic portion oriented towards the hydrophilic phase (e.g. aqueous solution). This typically results in a lowering of the surface tension or the interfacial tension. The term surfactant is used herein in its common meaning in the art.

[0048] The term “active agent” as used herein refers to a compound in a cosmetic composition that helps preserve the skin, hair, or other body parts in their natural condition and to objectively modify or improve the condition of the skin, hair, or other body parts as well as to protect the skin, hair, or other body parts. The term active agent is used herein in its common meaning in the art. Examples of such active agents are organic and / or inorganic UV filters, moisturizers, anti-aging agents, conditioning agents, protective proteins, enzymes, vitamins, retinol, or caffeine.

[0049] Particular embodiments of the invention

[0050] Solid granular material

[0051] The first aspect of the invention relates to a solid granular material for use in the preparation of a personal care product characterized in that the solid granular material comprises

[0052] (a) 1.0 to 30.0 wt.% liquid additive,

[0053] (b) 10.0 to 98.0 wt.% carrier,

[0054] (c) 0.1 to 50.0 wt.% surfactant,

[0055] (d) optionally up to 70.0 wt.% active agent, each based on the total weight of the solid granular material, wherein the liquid additive (a) comprises an emollient, wherein the solid granular material comprises the emollient in an amount of from 1.0 to 30.0 wt.%, based on the total weight of the solid granular material, and wherein the emollient is selected from the group consisting of propylene glycol dicaprylate / dicaprate, cocoglycerides, caprylic / capric triglyceride, isopropyl myristate, octyldodecyl myristate, decyl oleate, propylheptyl caprylate, isorbide dicaprylate, cetearyl isononanoate, caprylyl caprylate / caprate, pentaerythrityl tetraethylhexanoate, coco- caprylate / caprate, oleyl erucate, isononyl isononanoate, methyl soyate, dibutyl adipate, dibutyl adipate being more than 50% biobased, C12-15 alkyl benzoate, hexyl laurate, ethylhexyl stearate, ethylhexyl palmitate, cetyl palmitate, myristyl myristate, PPG-15 stearyl ether, coco-caprylate, hexyldecyl laurate, lauryl lactate, dibutyl sebacate, hexyldecyl stearate, octyldodecanol, hexyldecanol, tridecane, undecane, n-dodecane, squalane, isododecane, isohexadecane, dicaprylyl ether, dicaprylyl carbonate, dipropylheptyl carbonate, butyrospermum parkii (shea) butter, olus oil, passiflora incarnata seed oil, and mixtures thereof. It was surprisingly found that the solid granular material of the invention results in a smooth, lump-free personal care product after dissolution. The personal care products obtained from the inventive solid granular material provide a smooth feeling on the skin without any residual solid particles. The personal care products can be obtained from the solid granular material by the end user by simply adding a dissolution solvent, in particular water, in the preferred quantity. In this manner, a large variety of different personal care products can be made from the general core structure of the solid granular material of the invention. Possible personal care products that can be obtained encompass sunscreens, hair care products, conditioners, face care products, make-up products, body lotion and toothpaste. Due to the high level of flexibility regarding the further ingredients and the possibility of producing even small charges of material, it is possible to provide highly personalized and specialized personal care products.

[0056] It is a particular advantage of the present invention that the solid granular material described herein allows for the direct preparation of personal care products that are emulsions.

[0057] The solid granular material of the invention has a long shelf-life and allows for the use of water-sensitive components. The concentrated form of the solid granular materials reduces transport costs and makes transportation more ecological due to the reduced transportation weight. Furthermore, the solid granular material of the invention results in a reduced use of plastic containers. Due to the higher stability, the need for preservatives is also reduced.

[0058] The inventive solid granular material comprises at least three components: (a) 1.0 to 30.0 wt.% of a liquid additive, (b) 10.0 to 98.0 wt.% of a carrier and (c) 0.1 to 50.0 wt.% of a surfactant, wherein the liquid additive (a) comprises an emollient and wherein the emollient is selected from the group consisting of propylene glycol dicaprylate / dicaprate, cocoglycerides, caprylic / capric triglyceride, isopropyl myristate, octyldodecyl myristate, decyl oleate, propylheptyl caprylate, isorbide dicaprylate, cetearyl isononanoate, caprylyl caprylate / caprate, pentaerythrityl tetraethylhexanoate, coco-caprylate / caprate, oleyl erucate, isononyl isononanoate, methyl soyate, dibutyl adipate, dibutyl adipate being more than 50% biobased, C12-15 alkyl benzoate, hexyl laurate, ethylhexyl stearate, ethylhexyl palmitate, cetyl palmitate, myristyl myristate, PPG-15 stearyl ether, coco-caprylate, hexyldecyl laurate, lauryl lactate, dibutyl sebacate, hexyldecyl stearate, octyldodecanol, hexyldecanol, tridecane, undecane, n-dodecane, squalane, isododecane, isohexadecane, dicaprylyl ether, dicaprylyl carbonate, dipropylheptyl carbonate, butyrospermum parkii (shea) butter, olus oil, passiflora incarnata seed oil, and mixtures thereof. These three components provide the general structure and function of the solid granular material. Depending on the specific applicational needs, the properties may be amended by use of specific further components and by selecting a specific liquid additive, carrier and / or surfactant as discussed in the following.

[0059] Liquid additive (a)

[0060] The inventive solid granular material comprises 1.0 to 30.0 wt.% of a liquid additive, based on the total weight of the solid granular material. The liquid additive facilitates and assists in the formation of the granular material from a blend. The liquid additive is further required for the structural integrity and stability of the granular material of the invention.

[0061] The liquid additive (a) comprises an emollient. The solid granular material comprises the emollient in an amount of from 1.0 to 30.0 wt.%, based on the total weight of the solid granular material. The emollient is selected from the group consisting of propylene glycol dicaprylate / dicaprate, cocoglycerides, caprylic / capric triglyceride, isopropyl myristate, octyldodecyl myristate, decyl oleate, propylheptyl caprylate, isorbide dicaprylate, cetearyl isononanoate, caprylyl caprylate / caprate, pentaerythrityl tetraethylhexanoate, coco- caprylate / caprate, oleyl erucate, isononyl isononanoate, methyl soyate, dibutyl adipate, dibutyl adipate being more than 50% biobased, C12-15 alkyl benzoate, hexyl laurate, ethylhexyl stearate, ethylhexyl palmitate, cetyl palmitate, myristyl myristate, PPG-15 stearyl ether, coco-caprylate, hexyldecyl laurate, lauryl lactate, dibutyl sebacate, hexyldecyl stearate, octyldodecanol, hexyldecanol, tridecane, undecane, n-dodecane, squalane, isododecane, isohexadecane, dicaprylyl ether, dicaprylyl carbonate, dipropylheptyl carbonate, butyrospermum parkii (shea) butter, olus oil, passiflora incarnata seed oil, and mixtures thereof.

[0062] The use of the emollient allows for the preparation of an emulsion-type personal care product.

[0063] Particularly preferred emollients according to the present invention are selected from C12-15 alkyl benzoate, caprylic / capric triglyceride, dibutyl adipate, propylheptyl caprylate, dicaprylyl carbonate and mixtures thereof, most preferred dicaprylyl carbonate.

[0064] Particularly preferred quantities of emollient in the solid granular material are from 0.5 to 25.0 wt.%, preferably from 2.0 to 20.0 wt.%, further preferred from 3.0 to 15.0 wt.%, and even more preferred from 3.5 to 10 wt.%, based on the total weight of the solid granular material.

[0065] According to one embodiment of the invention, the liquid additive further comprises a humectant, a granulation liquid, or mixtures thereof. Humectants, emollients, and granulation liquids fulfil similar but somewhat different functions when used as liquid additive in the granular material. According to a preferred embodiment, two or all three of these types of liquid additives may be combined in the solid granular material. Multiple different humectants, emollients, and granulation liquids can be used together.

[0066] Any of the combinations of the preferred types of liquid additive is possible. According to one embodiment, the solid granular material comprises 1.0 to 30.0 wt.% of a liquid additive, wherein the liquid additive is a combination of humectant and emollient. According to another embodiment, the solid granular material comprises 1.0 to 30.0 wt.% of a liquid additive, wherein the liquid additive is a combination of emollient, humectant and granulation liquid. According to another embodiment, the solid granular material comprises 1.0 to 30.0 wt.% of a liquid additive, wherein the liquid additive is a combination of granulation liquid and emollient.

[0119] The solid granular material of the invention can also comprise any other type of additional additive that is useful for the personal care product. Possible further additives comprise preservatives, pH regulators / pH adjustment agents, consistency agents, and rheology modifiers.

[0120] Properties of the solid granular material

[0121] The solid granular material according to the invention can broadly vary in shape, form, size, and structure. According to a particularly preferred embodiment, the solid granular material is in the form of an extruded granule. That means that the solid granular material is obtained from an extrusion process. The extruded granular form of the solid granular material ensures that there is no dust formation, and that the solid granular material has a good flowability. The solid granular material of the invention has particularly good dissolution properties. According to one preferred embodiment of the invention, 4 g of the solid granular material of the invention dissolves completely in 36 g water at a shear rate of 200 / s at 23 ° C in less than 180 min, preferably in less than 150 min, preferred in less than 120 min, more preferred in less than 90 min, even more preferred in less than 60 min, further more preferred in less than 50 min, even further more preferred in less than 40 min or in less than 35 min, very preferred in less than 30 min, or most preferred in less than 25 min. Hereby, the minimum time of full dissolution (“dissolves completely”) is defined as the time when the peak of maximum viscosity is reached and no solid particles are visible on a macroscopic scale. The method to determine the dissolution properties of the material encompass providing 36 g of water in a beaker and adding 4 g of solid granular material while stirring. Subsequently, the mixture of solid granular material in water is homogenized with a four-blade agitator at a share rate of 200 / s at 23 ° C.

[0122] The solid granular material of the invention is preferably pourable and flowable. This property can be described with the flowability of the solid granular material. According to a preferred embodiment of the invention, the solid granular material has a flowability defined as the absolute flow factor FLA (also: FL) of at least 25. A FLA value of 25 represents a cohesionless bulk material.

[0123] The flowability of the solid granular material is preferably determined by determining the granules ability to fall freely through an orifice in a disk. This can be preferably done by using a powder flowability testing system such as the Flodex® Powder Flowability tester (Teledyne Hanson Flodex® tester). The system comprises a set of disks with different orifices sizes ranging from, for example, 4 mm to 34 mm.

[0124] The method to determine the flowability is detailed in A. Gioia, “ Intrinsic flowability: a new technology for powder-flowability classification" , Pharmaceutical Technology Magazine, Feb. 1980.

[0125] The size of the solid granular material can vary within broad ranges. According to a preferred embodiment, the solid granular material has a medium value of the particle size distribution Dv50 characterized by laser diffraction of 0.15 mm to 3.00 mm, preferably from 0.50 mm to 1.50 mm. For Dv determination using laser diffraction, many commercial instruments are available, for example from Anton Paar (PSA series), Microtrac MRB (Sync) or Malvern Panalytical (Mastersizer series). Depending on sensitivity and resolution of the selected instrument, the numerical results characterizing the particle size distribution will differ within some minor range. The skilled person knows how to deal with these deviations, and such instruments are routinely used in R&D and quality control labs. According to the present invention, Dv50-values are preferably determined by laser diffraction analysis using a Malvern Mastersizer 2000 equipped with a HydroG dispersing unit.

[0126] According to another preferred embodiment of the invention, the solid granular material which is preferably in the form of an extruded granule is further sphere-shaped or rodshaped. It is particularly preferred that the ratio of the length in mm to the diameter in mm of the solid granular material is from 1 to 20.

[0127] According to one preferred embodiment of the invention, the solid granular material for use in the preparation of a personal care product is for use in the preparation of a personal care product that is an emulsion, in particular a O / W or a W / O emulsion.

[0128] According to one preferred embodiment of the invention, the solid granular material for use in the preparation of a personal care product is for use in the preparation of a leave-on personal care product.

[0129] According to one embodiment, the solid granular material is not a bath agent composition.

[0130] Preparation Method

[0131] According to a second aspect of the invention, the invention relates to a method for preparing the inventive solid granular material. The method of the invention comprises the steps: a. Mixing a liquid additive (a), a carrier (b), a surfactant (c) and optionally an active agent (d) of the solid granular material to obtain a wet blend, wherein the liquid additive (a) comprises an emollient, wherein the emollient is selected from the group consisting of propylene glycol dicaprylate / dicaprate, cocoglycerides, caprylic / capric triglyceride, isopropyl myristate, octyldodecyl myristate, decyl oleate, propylheptyl caprylate, isorbide dicaprylate, cetearyl isononanoate, caprylyl caprylate / caprate, pentaerythrityl tetraethylhexanoate, coco-caprylate / caprate, oleyl erucate, isononyl isononanoate, methyl soyate, dibutyl adipate, dibutyl adipate being more than 50% biobased, C12-15 alkyl benzoate, hexyl laurate, ethylhexyl stearate, ethylhexyl palmitate, cetyl palmitate, myristyl myristate, PPG-15 stearyl ether, coco-caprylate, hexyldecyl laurate, lauryl lactate, dibutyl sebacate, hexyldecyl stearate, octyldodecanol, hexyldecanol, tridecane, undecane, n-dodecane, squalane, isododecane, isohexadecane, dicaprylyl ether, dicaprylyl carbonate, dipropylheptyl carbonate, butyrospermum parkii (shea) butter, olus oil, passiflora incarnata seed oil, and mixtures thereof, b. Extrude the wet blend using an extruder to obtain an extruded product, c. Breaking up of the extruded product to obtain wet pellets, d. Dry the wet pellets to obtain the solid granular material.

[0136] Kit-in-part

[0137] According to a third aspect of the invention, the invention relates to a kit-in-part comprising at least a first inventive solid granular material and a second inventive solid granular material for the preparation of a personal care product.

[0138] One advantage of the inventive solid granular material is the possibility to provide personalized personal care products. This can be done by combining different solid granular materials of the present invention with one another. In this manner, a broad range of modified personal care products can be obtained. The first and the second inventive solid granular material must differ in at least one aspect, for example in the components of the material or the ratio of the components. There is no limitation on how many different solid granular materials can be combined in the inventive kit-in-parts, however, typical numbers may range from two to five, in particular from two to four different solid granular materials.

[0139] All details laid out for the solid granular material also apply equally to the kit-in-part of the invention, in particular regarding the liquid additive (a), carrier (b), surfactant (c), active agent (d), further additives as well as the properties of the solid granular material. The present invention is further illustrated by the following examples.

[0140] Examples

[0141] Comparative Example 1 - Granules for hair conditioner (w / o carrier component)

[0142] A premix 1 was prepared by mixing together 1 g caprylic / capric triglyceride (emollient; Myritol® 312 from BASF Care creations), 4 g cetrimonium chloride (conditioning agent; Dehydquart A-CA from BASF Care creations), 0.4 g linalool (perfume, BASF care creations), 0.5 g sodium benzoate (preservative, Sigma Aldrich, p.a.) and 0.1 g citric acid (pH adjustment). Cetearyl alcohol (surfactant; Lanette® 0 from BASF Care creations) was melted separately and 3.5 g of the melted cetearyl alcohol was added to the premix 1.

[0143] The mixture was left to cool to room temperature and then extruded using a Caleva Multilab (CML) extrusion system comprising a multi-die plate with 26 holes with a 1 mm diameter at a rotation speed of approximately 100 rpm. The extrudates obtained were brittle and it was not possible to spheronize them due to the brittleness of the extrudates. The extrudates were dried overnight in a fume hood.

[0144] For the redispersion trial, 1.2 g granules were mixed with 18.8 g warm water (-40° C) and mixed by hand and additionally gently homogenized on a roller mixer. The redispersed material was liquid with a low viscosity. The redispersed material did not provide the same structure or feel as a basic conditioner prepared using standard preparation methods and was not suitable for use as hair conditioner.

[0145] For the basic conditioner prepared by standard preparation methods: Preparation of two separate Phases A (3.5 wt.% Cetearyl Alcohol (Consistency agent) and 1.0 wt.% Caprylic / Capric Triglyceride (Emollient)) and B (90.7 wt.% water and 4.0 wt.% Cetrimonium Chloride (conditioning agent)) by stearing and heating at 80-85° C. Then, addition of phase B to phase A while stirring and further homogenizing with Ultra-Turax (rotor-stator) at 50- 55° C. Addition of a Phase C containing 0.3 wt.% perfume, 0.5 wt.% sodium benzoate (preservative) and adjusting the pH to below 5 using citric acid.

[0146] Example 2 - Granules for hair conditioner (with carrier component)

[0147] The same process as in comparative example 1 was carried out. First, a premix 1 was prepared with the same components as in comparative example 1. Next, cetearyl alcohol (surfactant; Lanette® O from BASF Care creations) was melted separately and 3.5 g of the melted cetearyl alcohol was added to the premix 1. However, after addition of the melted cetearyl alcohol to premix 1, 1 g of a 1:1 (by weight) mixture of lactose (carrier; from Sigma Aldrich) and modified starch (carrier; Capsul® HF from Ingredion) was added to the warm mixture. To this, 4 x 1 g microcrystalline cellulose (carrier; from Alfa Aesar) was added. After each of the four additions of microcrystalline cellulose, the mixture was homogenized in a mixer at 2000 rpm (Thinky® mixer model ARE-250).

[0148] The resulting mixture was left to cool to room temperature and then extruded using a Caleva Multilab (CML) extrusion system comprising a multi-die plate with 26 holes with a 1 mm diameter at a rotation speed of approximately 100 rpm. The extrudates obtained from the extrusion process were spheronized using the Caleva Multilab (CML) extrusion system and the resulting particles were dried in a fume hood overnight.

[0149] For the redispersion trials, 2.2 g of granules were mixed with 17.8 g warm water (-40° C) and mixed by hand and additionally gently homogenized on a roller mixer. The resulting gel had very similar properties and a very similar feel as a basic conditioner prepared using standard preparation methods. The gel was well suited for the application as hair conditioner.

[0150] Example 3 - Granules for face cream

[0151] A solid blend was prepared by milling 2.6 g alkyl polyglucoside (surfactant, Emulgade PL68 / 50 from BASF care creations) with 0.4 g sodium stearoyl glutamate (surfactant, Emulgin SG from BASF care creations), 1.3 g glyceryl stearate (consistency agent, Cutina GMS V from BASF care creations), 0.5 g xanthan gum (thickener, Rheocare® XGN from BASF care creations), 0.5 g sodium benzoate (preservative), and 0.2 g citric acid (pH adjustment) in an IKA multidrive system. Next, the solid blend was transferred to a planetary mixter (Thinky® mixer model ARE-250) and 6.9 g dicaprylyl carbonate (emollient, Cetiol® CC from BASF care creations) was added and the mixtures was mixed to obtain a premix 1.

[0152] 10 g of a homogenous mixture of lactose (Sigma-Aldrich) and microcrystalline cellulose (Alfa Aesar) in a 1:1 weight-ratio was prepared as premix 2 and added to premix 1. The addition was performed slowly to avoid any significant temperature increases in the mixture.

[0153] Then, the mixture was humidified prior to the extrusion process by adding 1.5 g deionized water (granulation liquid). Subsequently, the humidified mixture was extruded using a Caleva Multilab (CML) extrusion system comprising a multi-die plate with 26 holes with a 1 mm diameter at a rotation speed of approximately 100 rpm. The same system was used to spheronize the extruded product. After spheronization, the particles were dried overnight in a fume hood.

[0154] For the redispersion trials, 9 g of the particles were fully redispersed by hand in 31 g warm water (-40° C). The resulting lotion had a pH of 4.8 and was physically stable in storage tests at 40 ° C for at least 10 weeks. In sensorics assessment, the lotion penetrated rapidly and provided a smooth, pleasant feel on the skin.

[0155] Example 4 - Granules for sunscreen with water

[0156] A premix 1 was prepared by mixing 2.5 g lactose (carrier) with 10 g 2-phenylbenzimidazole- 5-sulfonic acid (PBSA, UV filter, Eusolex® 232 from Merck KGaA), 3 g sodium carbonate (pH adjustment), and 1 g xanthan gum (thickener; Rheocare® XGN from BASF care creations) in a stand mixer. Then, a premix 2 comprising 0.13 g polysorbate 80 (surfactant, Tween® 80), 0.12 g sorbitan monooleate (surfactant, Span® 80), and 0.75 g Caprylic / capric triglycerides (emollient, Miglyol® 812) was prepared and added to the premix 1. 3 g water (granulation liquid) was added stepwise to the mixture.

[0157] The mixture was then extruded and spheronized using a Caleva Multilab (CML) extrusion system comprising a multi-die plate with 26 holes with a 1 mm diameter at a rotation speed of approximately 100 rpm. The extruded solid granular material was dried in a fume hood overnight.

[0158] The granules obtained were redispersed adding 16 g warm water (-40° C) to 4 g of granules by manual shaking. The granules dissolved well and resulted in a homogenous mixture, ready-to-use as sunscreen.

[0159] Example 5 - Granules for sunscreen without water

[0160] A premix 1 was prepared by mixing 1.25 g lactose (carrier) with 5 g 2-phenylbenzimidazole- 5-sulfonic acid (PBSA, UV filter, Eusolex® 232 from Merck KGaA), 1.5 g sodium carbonate (pH adjustment), and 0.5 g xanthan gum (thickener; Rheocare® XGN from BASF care creations) in a stand mixer. Then, a premix 2 comprising 0.06 g polysorbate 80 (surfactant, Tween® 80), 0.06 g sorbitan monooleate (surfactant, Span® 80), and 0.38 g Caprylic / capric triglyceride (emollient, Miglyol® 812) was prepared and added to the premix 1. 2.25 g dibutyl adipate (granulation liquid) was added stepwise to the mixture.

[0161] The mixture was then extruded and spheronized using a Caleva Multilab (CML) extrusion system comprising a multi-die plate with 26 holes with a 1 mm diameter at a rotation speed of approximately 100 rpm. The extruded solid granular material was dried in a fume hood overnight.

[0162] The granules obtained were redispersed adding 16 g warm water (-40° C) to 4 g of granules by manual shaking. The granules dissolved well and resulted in a homogenous mixture, ready-to-use as sunscreen.
