Description

Cosmetic composition, and use of a combination of Oryza sativa starch and at least one natural organic thickener. Technical area

[001] The present invention relates to a cosmetic composition comprising oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and a natural organic thickener, as well as to the use of a combination of oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and a natural organic thickener for the stabilization of a cosmetic composition. Background

[002] Cosmetic compositions represent a ubiquitous part of modern life. Cosmetic compositions encompass no-rinse products such as skin and body care products, including daily care compositions and sunscreens, hair care including shampoos, conditioners, shower gels, makeup, and many other products. The requirements for such cosmetic compositions are constantly increasing, whether in relation to performance, sustainability, or cost. In particular, the sustainability of cosmetic compositions is becoming increasingly relevant to consumers and regulators.

[003] In this sense, the use of microplastics and synthetic polymers in general in cosmetic compositions has been the subject of increasing scrutiny. There is a growing consumer demand for cosmetics free of microplastics and, in general, synthetic polymers. Therefore, cosmetic compositions free of microplastics and synthetic polymers in general are desirable.

[004] Another important aspect of sustainability is the origin of the material. In this sense, bio-based materials are becoming increasingly desirable. In contrast to materials derived from resources Petition 870250080583, dated 08 / 09 / 2025, page 10 / 50 / 35 Although fossil fuels, such as synthetic polymers, bio-based materials have a substantially smaller carbon footprint. Unfortunately, these materials often do not offer the same performance as conventional materials derived from fossil resources.

[005] An important requirement for cosmetic compositions is formulation stability, especially during longer storage periods. This is particularly challenging for sunscreens due to the number of different components that such compositions usually comprise, for example, liquid or solid UV filters, water- or oil-soluble, particulate UV filters, solubilizers, emulsifiers, and so on. Sunscreens generally contain a high oil load, which affects the physical (macroscopic) stability of the formulation and makes it difficult to obtain a high viscosity composition. Sunscreens are also used in extreme temperature conditions, i.e., in hot summers or cold winters, which presents an additional challenge to product stability.

[006] These factors can contribute to the separation of components or phases within the cosmetic composition and therefore result in a non-homogeneous composition. This process can occur rapidly, in a few days, or slowly, over several weeks or months. However, the formation of a non-homogeneous and unstable composition can greatly impact the product's appearance, sensory properties, or, even worse, the performance of a personal care product. For example, a non-homogeneous and unstable sunscreen composition may no longer provide the promised and expected protection against UV radiation.

[007] Therefore, there is a continuing need to develop sustainable cosmetic compositions with good medium to long-term stability and free of microplastics. Summary of the Invention Petition 870250080583, dated 08 / 09 / 2025, page 11 / 50 / 35

[008] Therefore, an objective of the present invention is to provide a cosmetic composition comprising bio-based materials.

[009] Furthermore, an objective of the present invention is to provide a cosmetic composition that is particularly sustainable due to its bio-based materials.

[0010] Furthermore, an objective of the present invention is to provide a cosmetic composition that is free of microplastics and / or synthetic polymeric materials.

[0011] Another objective of the invention is to provide a cosmetic composition with high macroscopic stability and long-term storage stability.

[0012] Another objective of the invention is to provide a cosmetic composition with high viscosity, suitable for different personal care applications.

[0013] According to a first aspect, the invention relates to a cosmetic composition comprising Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and at least one natural organic thickener, wherein the cosmetic composition comprises less than 0.1% by weight of synthetic polymeric material, based on the total weight of the cosmetic composition, and wherein the cosmetic composition comprises at least one organic or inorganic UV filter. It has been found that at least one of the objectives of the invention can be achieved with such a cosmetic composition.

[0014] During a comprehensive investigation into potential bio-based materials for application in cosmetic compositions, such as sunscreens or daily care compositions with or without UV protection, it was surprisingly found that a specific type of starch, Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) – obtained from rice – greatly increases the stability of a cosmetic composition if the starch is combined with at least one natural organic thickener. Interestingly, Petition 870250080583, dated 08 / 09 / 2025, page 12 / 50 / 35 neither rice starch alone nor the natural organic thickener alone can provide sufficient stability to a cosmetic composition. However, these two bio-based materials combined allow for the delivery of a high-viscosity cosmetic composition that remains stable for several weeks and months. When these two bio-based materials are used in combination, no further synthetic polymer-based thickeners, synthetic polymer binders, synthetic polymer water-retaining agents, or any type of synthetic polymer material are needed to obtain a cosmetic composition with excellent viscosity properties. This is even true for sunscreen compositions that have a particularly complex ingredient composition with a high oil load.

[0015] Without being linked to any specific scientific theory, it appears that the interaction of Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) with at least one natural organic thickener provides a stable and long-lasting structure to the formulation. The viscosity of the composition remains stable even during long periods of storage.

[0016] The second aspect of the invention relates to the use of a combination of Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and at least one natural organic thickener for the stabilization of a cosmetic composition, wherein the cosmetic composition comprises less than 0.1% by weight of synthetic polymeric material, based on the total weight of the cosmetic composition, and wherein the cosmetic composition comprises at least one organic or inorganic UV filter. As stated in relation to the first aspect of the invention, it has been surprisingly found that a combination of Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and a natural organic thickener effectively stabilizes cosmetic compositions. These two components provide the necessary structural integrity for different types of cosmetic compositions and provide stability. Petition 870250080583, dated 08 / 09 / 2025, page 13 / 50 / 35 of long-term relevance to these cosmetic compositions.

[0017] The third aspect of the invention relates to the use of a combination of Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and at least one natural organic thickener to increase the viscosity of a cosmetic composition, wherein the cosmetic composition comprises less than 0.1% by weight of synthetic polymeric material, based on the total weight of the cosmetic composition, and wherein the cosmetic composition comprises at least one organic or inorganic UV filter.

[0018] The fourth aspect of the present invention relates to a method for preparing the inventive cosmetic composition by providing Oryza sativa starch (INCI Oryza Sativa (Rice) Starch), at least one natural organic thickener and other ingredients for a cosmetic composition, mixing the Oryza sativa starch (INCI Oryza Sativa (Rice) Starch), at least one natural organic thickener and the other ingredients to obtain the cosmetic composition, wherein the cosmetic composition comprises less than 0.1% by weight of synthetic polymeric material, based on the total weight of the cosmetic composition and wherein the cosmetic composition comprises at least one organic or inorganic UV filter.

[0034] The term “substituted”, as used in this document, means that a hydrogen atom bonded to a designated atom is replaced with a specified substituent, provided that the substitution results in a stable or chemically viable compound. Unless otherwise indicated, a substituted atom may have one or more substituents and each substituent is selected independently.

[0035] The term “cosmetic composition” refers to any topical product intended to be applied to the human body for cleansing, beautifying, enhancing attractiveness, altering the appearance or protecting the skin without affecting the structure or function of the body. Possible cosmetic compositions within the meaning of the invention include no-rinse products such as facial and body care products, including daily care compositions with or without UV protection and sunscreens, hair care products such as shampoos, conditioners, shower gels, makeup compositions and similar compositions.

[0036] The term “sunscreen composition” or “sunscreen” refers to any topical product that absorbs and may further reflect and scatter certain portions of UV radiation. Thus, the term “sunscreen composition” should be understood not only as 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 may refer, for example, to sprays, lotions, creams, oils, foams, powders, or gels. According to the present invention, the sunscreen composition Petition 870250080583, dated 08 / 09 / 2025, page 18 / 50 / 35 may include one or more active agents, for example, organic and inorganic UV filters, as well as other ingredients or additives, for example, emulsifiers, emollients, viscosity regulators, stabilizers, preservatives or fragrances.

[0037] The term “daily care composition” refers to any topical product intended for daily use with or without UV protection. If UV protection is included, it absorbs and may reflect and scatter certain portions of UV radiation and is used as a daily care product for the human body, for example, for the face or body. The daily care composition may comprise one or more active agents, for example, organic and / or inorganic UV filters, as well as other ingredients or additives, for example, emulsifiers, emollients, viscosity regulators, stabilizers, preservatives, or fragrances. Suitable daily care compositions according to the present invention include, for example, no-rinse facial and body care products.

[0038] No-rinse products suitable for face and body are, for example, sunscreen preparations and skin care preparations.

[0039] Suitable preparations for skin care are, for example, moisturizing, anti-aging, refining, and lifting preparations. The leave-on compositions mentioned may be in the form of creams, ointments, pastes, foams, gels, lotions, powders, makeup, sprays, sticks, or aerosols. Daily care compositions with UV protection protect human skin against damage caused by UV light.

[0040] The term “UV filter” or “ultraviolet filter,” as used in this document, refers to organic or inorganic compounds that can absorb and may additionally reflect and scatter UV radiation caused by sunlight. UV filters can be classified based on their UV absorption profile as UV-A, UV-B, or broadband filters. Preferably, Petition 870250080583, dated 08 / 09 / 2025, page 19 / 50 / 35 the term “UV filter” includes or consists of any UV filter as defined in Annex VI (version of 11.11.2022) of Regulation (EC) No 1223 / 2009 of the European Parliament and of the Council.

[0041] The term “stabilization of a cosmetic composition” is defined according to the present invention as the stabilization of the structural integrity of the cosmetic composition. The stabilization of the structural integrity of the cosmetic composition is preferably determined by visual assessment (macroscopic stability) at different storage temperatures over time, microscopic assessment, centrifugal analysis, viscosity and pH measurement over time; more preferably, stabilization is determined by visual assessment. Visual assessment is performed by determining, through an eye test, whether the composition remains homogeneous (e.g., without oil release, without water separation). Centrifugal assessment can be used as an accelerated stability test.To determine whether the combination of Oryza sativa starch and a natural organic thickener results in the stabilization of a cosmetic composition, the stability of a cosmetic composition is evaluated by one of the methods mentioned in the preceding sentences, once without the addition of the combination of Oryza sativa starch and a natural organic thickener and once with the addition of the combination of Oryza sativa starch and a natural organic thickener. It was found that the use of the inventive combination of Oryza sativa starch and a natural organic thickener leads to a more stable cosmetic composition compared to a composition that does not comprise this combination.

[0042] Water-soluble UV filters have a solubility in water of at least 2% by weight, preferably at least 3% by weight, more preferably at least 5% by weight.

[0043] Oil-soluble filters have a solubility in specific emollients of at least 2% by weight, preferably at least 3% by weight. Petition 870250080583, dated 08 / 09 / 2025, page 20 / 50 / 35 weight, more preferably at least 5% by weight.

[0044] The term “emollient” refers to specific cosmetic oils used to protect, hydrate, and lubricate the skin. The word emollient derives from the Latin mollire, meaning to soften. In general, emollients prevent water evaporation from the skin by forming an occlusive coating. Alternatively, or additionally, emollients improve the distribution of the product on the skin. Emollients can be divided into different groups depending on their polarity index.

[0045] The term “sensitive skin” refers to skin whose natural barrier function is weakened and 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 skincare compositions.

[0046] The term “sun protection factor (SPF),” as used in this document, indicates how well the skin is protected by a sunscreen composition, primarily from UV-B radiation. In particular, the factor indicates how long protected skin can be exposed to the sun without burning compared to untreated skin. For example, if a sunscreen composition with an SPF of 15 is applied evenly to the skin of a person who usually burns after 10 minutes in the sun, the sunscreen allows the skilled individual to remain in the sun 15 times longer. In other words, SPF 15 means that 1 / 15 of the UV radiation will reach the skin, assuming the sunscreen is applied evenly in a thick dosage of 2 milligrams per square centimeter (mg / cm2).

[0047] The definition of “broadband” protection (also called broad spectrum or broad protection) can be based, for example, on the “critical wavelength” or UVA-PF. For broadband coverage, UV-B and UV-A protection must be provided. According to the requirements Petition 870250080583, dated 08 / 09 / 2025, page 21 / 50 / 35 from the USA, a critical wavelength of at least 370 nm is necessary to obtain broad-spectrum protection. Furthermore, the European Commission recommends that all sunscreens or cosmetic compositions have a UV-A protection factor that is at least one-third of the indicated sun protection factor (SPF), for example, if the sunscreen composition has an SPF of 30, the UVA protection factor should be at least 10.

[0048] 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 to 400 nm). For example, a critical wavelength of 370 nm indicates that the protection of the sunscreen composition is not limited to UV-B wavelengths, i.e., wavelengths of 290-320 nm, but extends to 370 nm in such a way that 90% of the total area under the protection curve in the UV region is achieved at least at 370 nm.

[0049] The term “administration” refers to the application of a sunscreen or daily care composition to a person's skin.

[0050] In this invention, the term “rice starch” refers to Oryza sativa starch (INCI Oryza Sativa (Rice) Starch), unless otherwise indicated.

[0051] The term “natural” in “natural organic thickener” refers to a component that is derived wholly or at least partially, preferably wholly, from natural resources. A natural resource is any biological or mineral good offered by nature. Natural resources, within the meaning of the invention, include, among others, plants, forests, vegetation, surface and groundwater, arable land, soil, and minerals. Natural resources, within the meaning of the invention, do not include products obtained from fossil resources such as petroleum, natural gas, crude oil, or coal. An alternative term for “natural” in this invention is the term “biologically based.” The terms should be used interchangeably in this invention. Petition 870250080583, dated 08 / 09 / 2025, page 22 / 50 / 35, even if the term “natural” is used in a context different from the context of “natural organic thickener”, the meaning of the term is the same as defined for “natural organic thickener”, unless otherwise indicated.

[0052] The term “organic” in “natural organic thickener” refers to an organic compound or mixture of organic compounds. An organic compound is any one of a large class of chemical compounds in which one or more carbon atoms are covalently bonded to atoms of other elements, most commonly carbon, hydrogen, oxygen, or nitrogen. The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides. If the term “organic” is used in a context other than the context of “natural organic thickener,” the meaning of the term is the same as defined for “natural organic thickener,” unless otherwise indicated.

[0053] The term “thickener” in “natural organic thickener” refers to a component that increases the viscosity of a mixture. A thickener can lead to an increase in the viscosity of a composition, for example, by binding liquid, in particular water, present in the composition. In some cases, a thickener may form a gel when in contact with water. In other cases, a thickener may not gel when in contact with water. The person skilled in the art is familiar with typical thickeners and the general properties of thickeners. The terms “thickener” and “thickening agent” should be used interchangeably in this invention. If the term “thickener” is used in a context other than the context of “natural organic thickener,” the meaning of the term is the same as defined for “natural organic thickener,” unless otherwise indicated.

[0054] The term “synthetic thickener” refers to thickeners as defined above, which are, however, derived from fossil resources, in particular oil and gas, through various reaction and processing steps. Synthetic thickeners are man-made through Petition 870250080583, dated 08 / 09 / 2025, page 23 / 50 / 35 of synthesis and processing. The types of synthetic thickeners are synthetic polymers and microplastics with thickening activity. Common synthetic thickeners are polyacrylates or homopolymers of cross-linked acrylic acids or polyacrylamides, such as carbomers, acrylate copolymers, acrylate / C10-C30 alkyl acrylate crosspolymer, acrylate / beheneth-25 methacrylate copolymer, VP / eicosene copolymer, VP / hexadecene copolymer, and triacontanyl PVP. It is preferable that the inventive cosmetic composition be free of synthetic thickeners.

[0055] The term “microplastic” here refers to small solid particles made of a synthetic polymer. Some synthetic thickeners may be microplastics and vice versa. The solid particles of microplastics are often insoluble in water and preferably have a Dv50 particle size distribution of less than 5 mm. Examples of microplastics used in cosmetic compositions in the art are styrene / PVP or styrene-acrylamide copolymers, polyamide derivatives such as nylon-12; polymethyl methacrylates and polyethylene. It is also preferable that the inventive cosmetic composition be microplastic-free.

[0056] The term “synthetic polymeric material” here refers to polymeric material derived from fossil resources, particularly oil and gas, through various reaction and processing steps. The term “polymeric material” here refers to a material consisting of large molecules called macromolecules, which are composed of repeating subunits that chemically bond to form long polymer chains. Polymeric material is obtained through the polymerization of many small molecules, known as monomers. Synthetic thickeners and microplastics are part of the “synthetic polymeric material” group.

[0057] Statements made about components, features or properties relating to the first aspect of the invention also apply equally to the other aspects of the present invention. Petition 870250080583, dated 09 / 08 / 2025, p. 24 / 50 / 35. Statements regarding components, characteristics, or properties relating to the second aspect of the invention also apply equally to the other aspects of the present invention. Statements made about components, characteristics, or properties relating to the third aspect of the invention also apply equally to the other aspects of the present invention. Statements made about components, characteristics, or properties relating to the fourth aspect of the invention also apply equally to the other aspects of the present invention. Specific forms of the invention

[0058] The first aspect of the present invention relates to a cosmetic composition comprising Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and at least one natural organic thickener, wherein the cosmetic composition comprises less than 0.1% by weight of synthetic polymeric material, based on the total weight of the cosmetic composition, and wherein the cosmetic composition comprises at least one organic or inorganic UV filter. The combination of rice starch and at least one natural organic thickener in a cosmetic composition provides stability and structural integrity to a cosmetic composition for several weeks to months. The combination of Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and at least one natural organic thickener increases the viscosity of the cosmetic composition and allows the use of such a composition in many different fields of application in cosmetics.The combination of these two components results in an unexpected synergistic effect that is substantially greater than the effect of using Oryza sativa starch or at least one natural organic thickener alone. Furthermore, a composition comprising Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and at least one natural organic thickener has a smaller carbon footprint and greater sustainability compared to compositions based on conventional stabilizing systems. Petition 870250080583, dated 08 / 09 / 2025, page 25 / 50 / 35 synthetic thickeners. The cosmetic composition may also exhibit greater biodegradability than a composition based purely on components obtained from fossil resources and may be free of synthetic polymers and microplastics.

[0059] Generally, a wide range of different types of natural organic thickeners can be used in the present invention. According to a preferred embodiment of the invention, the natural organic thickener is selected from the group consisting of polysaccharides, polypeptides, proteins, and mixtures thereof. Polysaccharides, polypeptides, proteins, and mixtures thereof have been considered particularly suitable as natural organic thickeners in combination with Oryza sativa starch (INCI Oryza Sativa (Rice) Starch). Furthermore, polysaccharides, polypeptides, and proteins are readily available in nature and can be entirely bio-based.

[0060] According to another preferred embodiment of the invention, the natural organic thickener is a polysaccharide selected from the group consisting of natural gum, pectin, cellulose, chitin, callose, and mixtures thereof. Polysaccharides are readily available in nature, are fully biological, and effective at binding water.

Natural gums are excellent thickening agents in combination with Oryza sativa starch (INCI Oryza Sativa (Rice) Starch). They are readily available and economical.

[0062] The most preferred type of natural organic thickener is a natural gum selected from the group of xanthan gum, tara gum (Caesalpinia Spinosa gum), alginic acid / sodium alginate (algin) and mixtures thereof. According to one embodiment of the invention, the natural organic thickener is xanthan gum. According to another embodiment of the invention, the natural organic thickener is tara gum. According to yet another embodiment of the invention, the natural organic thickener is alginic acid / sodium alginate (algin). Xanthan gum, tara gum and algin are excellent natural thickeners that bind to the other components of the cosmetic composition particularly effectively when combined with Oryza sativa starch.

[0063] Oryza sativa starch particles (INCI Oryza Sativa (Rice) Starch) used in the present invention may be provided in different shapes or sizes.According to one embodiment, Oryza sativa starch particles (INCI Oryza Sativa (Rice) Starch) have a polygonal particle shape. The term “polygonal particle shape” here means that at least 75% of the number of particles in an Oryza sativa starch sample (INCI Oryza Sativa (Rice) Starch) have three or more vertices or corners, preferably four or more vertices or corners, even more preferably five or more vertices or corners, as identified by electron microscopy. Oryza sativa starch particles (INCI Oryza Sativa (Rice) Starch) with a polygonal particle shape are particularly suitable for providing excellent structural integrity for cosmetic compositions.

[0064] The Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) used in the present invention may also have different particle size distributions. According to a preferred embodiment, the starch of Petition 870250080583, dated 08 / 09 / 2025, page 27 / 50 / 35 Oryza sativa (INCI Oryza Sativa (Rice) Starch) has a Dv50 particle size distribution determined by static laser scattering of 2 to 10 μm, in particular 6 to 8 μm. Oryza sativa starch with this Dv50 value has proven to be particularly suitable for providing ideal structural stability to a cosmetic composition.

[0065] The Dv50 particle size distribution of Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) is preferably determined by static laser scattering. In the present invention, the Dv50 values ​​were determined using static laser scattering with a Beckman Coulter LS-13 230 liquid universal module particle size analyzer with PIDS using a 2% rice starch suspension in deionized water.

[0066] The Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) used in the inventive composition has the ability to bind liquids such as oil effectively. Preferably, the Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) has an oil absorption capacity of 0.5 to 1.0 g, preferably 0.7 to 0.8 g of oil per 1.0 g of starch. With such oil absorption capacity of the oryza sativa starch used, the cosmetic composition possesses particularly high viscosity and structural integrity.

[0067] Methods for determining the oil absorption capacity of a starch are known in the art. The oil absorption capacity of Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) can be determined by mixing a sample of Oryza sativa starch with excess oil in a weighed centrifuge tube to obtain a dispersion, centrifuging the dispersion, removing the supernatant completely, and then weighing the centrifuge tube containing the starch and the oil that was absorbed by the starch.

[00107] The description relating to the cosmetic composition of the present invention also applies mutatis mutandis to the use of a combination of Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and at least one natural organic thickener for stabilizing the cosmetic composition.

[00108] The invention also relates to the use of Oryza sativa starch (INCI Oryza Sativa (Rice) Starch) and at least one natural organic thickener to increase the viscosity of a cosmetic composition, wherein the cosmetic composition comprises less than 0.1% by weight of synthetic polymeric material, based on the total weight of the cosmetic composition, and wherein the cosmetic composition comprises at least one organic or inorganic UV filter.

[00114] Algin formulations require the addition of a divalent cation, in this case calcium chloride dihydrate, to activate gel formation, creating a structure called an “egg crate” structure.

[00115] Each formulation was placed in a 250 mL glass vial and the viscosity of the different compositions Inventive Example 1-3 and Petition 870250080583, dated 08 / 09 / 2025, page 42 / 50 / 35 Comparative Example 1-4 was determined 24 hours after manufacture using a Brookfield DVIII. Furthermore, the stability of the different compositions was evaluated at room temperature after different times (24h, 1 month, 2 months, 3 months) by means of an eye test. Table 2 shows the results of the viscosity measurements and the macroscopic stability assessment. Comparative Example 1 Inventive Example 1 Comparative Example 2 Inventive Example 2 Comparative Example 3 Inventive Example 3 Comparative Example 4 Viscosity [mPa.s] 24h 1113 (LV2 shaft, 10 rpm) 8136 (RV5 shaft, 10 rpm) n / a 6104 (RV5 shaft, 10 rpm) 2369 (LV2 shaft, 10 rpm) 6632 (RV5 shaft, 10 rpm) 112 (LV2 shaft, 20 rpm) Visual stability (macroscopic) Unstable; separation of aqueous phases after 1 month Stable after 3 months Unstable; separation of aqueous phase after 24h stable after 3 months stable after 3 months stable after 3 months Unstable; separation of aqueous phases after 2 months Table 2: Viscosity and stability data for the different compositions; n / a: not applicable, unstable formulation

[00116] The data in Table 2 show that the inventive compositions exhibit a substantially higher viscosity than the comparative compositions. Rice starch alone does not provide sufficient thickening capacity to achieve an acceptable viscosity for a topical cosmetic composition (viscosity Comparative Example 4 p = 112 mPa.s). Furthermore, for this, the formulation showed phase separation after 2 months. Interestingly, adding rice starch to a composition containing a natural organic thickener increases the viscosity of all compositions studied by more than 2.5 times. The inventive compositions comprising rice starch and a natural organic thickener exhibit excellent stability over one and three months without any phase separation occurring.In contrast, comparative examples without rice starch (Comparative Example 1-3) show phase separation after storage for a certain period and / or viscosity properties below the ideal.

[00117] The compositions of comparative example 3 and example Petition 870250080583, dated 08 / 09 / 2025, page 43 / 50 / 35 Inventive Example 3, which contains xanthan gum as a natural organic thickener, remained stable after 3 months of storage, although the viscosity of the inventive composition was almost three times greater than that of the comparative composition. To mimic the effect of longer storage periods, an accelerated stability test was performed on the compositions of comparative example 3 and inventive example 3. A centrifugal evaluation was used as an accelerated stability test. For this purpose, 15 g of each formulation were transferred to centrifuge tubes. The centrifugation conditions were 10 minutes at 5000 rpm. The centrifuge used for the stability test was a Heraeus Multifuge X1R. After the centrifugation step, the two samples were analyzed for phase separation. In the case of inventive example 3, the formulation remained completely homogeneous even after centrifugation.In contrast, for the formulation of comparative example 3, a clearly visible phase separation was observed in the centrifuge tube after centrifugation. Therefore, a clear difference in stability can also be observed for the formulation of inventive example 3 in contrast to comparative example 3 when conducting an accelerated stability test by centrifugal evaluation.

[00118] The examples demonstrate that cosmetic compositions comprising Oryza sativa starch and at least one natural organic thickener exhibit excellent viscosity and stability properties.
