Description

[0001] DESCRIPTION

[0002] TITLE OF INVENTION

[0003] STABLE W / O EMULSION COMPOSITION

[0004] TECHNICAL FIELD

[0005] The present invention relates to a water in oil (W / O) emulsion composition, in particular a sun care composition in the form of a stable W / O emulsion, for a keratin material such as skin.

[0006] BACKGROUND ART

[0007] Sun care products are widely used in order to protect keratin materials, in particular skin, from the damage caused by UV radiation. Among sun care products, W / O emulsion sun care compositions are widely distributed since they are in general water resistant and thus can be retained on the surface of the skin even after exposed to water or sweat.

[0008] In sun care cosmetic products, organic UV filters are widely used to impart a UV protecting property to sun care compositions. However, the use of organic UV filters may have a negative impact such as causing a viscous property as well as sufficient stability to maintain their emulsion form over time.

[0009] Also, in recent years, the polluteing of the ocean environment and the destroyuction of the marineecosystem by microplastics have become a big concern. Therefore, cosmetic products including a small amount of microplastic fillers or not including microplastic fillers have been proposed.

[0010] Thus, there has been a demand for W / O emulsion compositions which have a lower viscosity and good stability without causing phase separation over time.

[0011] For example, WO2023 / 277194 discloses a W / O emulsion composition comprising:

[0012] (a) at least one lipophilic organic UV filter, (b) at least one powder other than microplastic filler, (c) at least one cationic polymer, and (d) at least one oil, wherein the composition comprises microplastic filler in an amount of 5% by weight or less, preferably 3% by weight or less, and more preferably 1% by weight or less, or the composition is free of microplastic filler.

[0013] However, the composition disclosed in WO2023 / 277194 may have a problem in that there may be a case that powders in the composition case an aggregation which may result in less stability of the composition.

[0014] Moreover, the formulation of environmentally-friendly cosmetic products, which are designed and developed considering environmental issues, is becoming a major goal in an effort to meet global challenges. It is therefore essential to propose more sustainable compositions, preparation processes and ingredients to address these environmental concerns.

[0015] In this context, it is important to develop new cosmetic compositions by promoting the use of renewable raw materials and / or materials with a good index of naturalness and / or materials of natural origin. Thus, there is still a demand to provide new formulation of low- viscose W / O emulsion compositions which has a sufficient stability with reduced amount of filler aggregation. Furthermore, sun care cosmetic compositions which do not contain microplastic fillers are also desired as environmentally- sustainable products.

[0016] DISCLOSURE OF INVENTION

[0017] An objective of the present invention is to provide a W / O emulsion composition having a low viscosity and a sufficient stability with reduced amount of an aggregation of fillers, and not substantively comprising microplastic fillers.

[0018] The above objective of the present invention can be achieved by a W / O emulsion composition, comprising:

[0035] The composition may further comprise at least one lipophilic UV filter.

[0036] The present invention also relates to a cosmetic process for a keratin material, such as skin, comprising applying to the keratin material the composition according to the present invention.

[0037] BEST MODE FOR CARRYING OUT THE INVENTION

[0038] After diligent research, the inventors have surprisingly discovered that a W / O emulsion composition comprising a combination of at least one cationic polymer having a molecular weight ranging from 20,000 to 500,000, at least one hydrophilic filler, and at least one organically modified clay can exhibit a low viscous property, good stability and reduced amount of filler aggregation, by forming a three dimensional (3D) network structure in the composition, and thus completed the present invention.

[0039] Thus, the present invention relates to a W / O emulsion composition, comprising:

[0040] (a) at least one cationic polymer having a molecular weight ranging from 20,000 to 500,000;

[0041] (b) at least one hydrophilic filler;

[0042] (c) at least organically modified clay; and

[0043] (d) at least one oily medium, wherein the composition comprises microplastic filler in an amount of 5% by weight or less, preferably 3% by weight or less, and more preferably 1% by weight or less, or the composition is free of microplastic filler.

[0044] Hereinafter, the W / O emulsion composition and cosmetic process according to the present invention will be explained in a more detailed manner.

[0045] [Composition]

[0046] The composition according to the present invention includes (a) at least one cationic polymer having a molecular weight ranging from 20,000 to 500,000, (b) at least one hydrophilic filler, (c) at least one organically modified clay, and (d) at least one oily medium.

[0047] The composition according to the present invention is a water in oil emulsion form, i.e., a W / O emulsion form, comprising multiple, discontinuous and dispersed aqueous phases in a continuous oily phase. Thus, the composition according to the present invention comprises multiple, discontinuous, and dispersed aqueous phases and one continuous oily phase.

[0048] The composition according to the present invention exhibits a low viscous property. For example, the composition of the present invention may have a viscosity of less than 10 Pa·s, preferably less than 8 Pa·s, and more preferably less than 6 Pa·s at room temperature (25 °C). The lower limit of the viscosity is not limited, but in general, the composition has a viscosity of more than 1 mPa·s at room temperature. In the contents of the present specification, the viscosity of the compositions can be measured with a B-type viscometer at room temperature.

[0049] The W / O emulsion composition according to the present invention can show a good stability without causing phase separation over time, even though it does not substantively include microplastic filler. In addition, the composition according to the present invention can suppress aggregations of fillers. These properties are surprising because in general low- viscous compositions tend to show low stability and cause filler aggregation, but the composition according to the present can satisfy a good stability with reduced amount of filler aggregation while it is low viscous.

[0050] While not wishing to be bound by theory, the inventors have surprisingly discovered that the combination of the (a) cationic polymer, the (b) hydrophilic filler, and (c) organically modified clay can form a three dimensional (3D) network structure in the composition to produce a structured bulk. In particular, it is believed that the (a) cationic polymer and the (b) hydrophilic filler in the discontinuous dispersed aqueous phases can interact with the (c) 1 organically modified clay in the continuous oily phase by ionic force, and thus the 3D network structure is created in the composition.

[0051] The level of the 3D structure in the composition can be measured by permittivity. Appropriate level of permittivity indicates more 3D structure is produced. Preferably, the permittivity of the present invention ranges from 1 to 2. The permittivity can be measured, for example, using a multi parameter meter, such as Orion™ Versa Star sold by Thermo Fisher Scientific at ambient condition.

[0052] The ingredients in the composition will be described in a detailed manner below.

[0054] The composition according to the present invention comprises (a) at least one cationic polymer having a molecular weight ranging from 20,000 to 500,000.

[0055] A cationic polymer has a positive charge density. The charge density of the cationic polymer may be from 0.01 meq / g to 20 meq / g, preferably from 0.05 lol 5 meq / g, and more preferably from 0.1 to 10 meq / g.

[0056] The cationic polymer may be hydrophilic or water soluble. Thus, in a preferred embodiment, the (a) cationic polymer is present in the aqueous phases of the W / O emulsion composition according to the present invention.

[0057] The molecular weight of the (a) cationic polymer ranges from 20,000 to 500,000. The molecular weight of the cationic polymer may range from 25,000 to 400,000.

The term (primary) “amino group” here means the -NH2group.

[0060] The (a) cationic polymer may be a homopolymer or a copolymer. The term “copolymer” is understood to mean both copolymers obtained from two kinds of monomers and those obtained from more than two kinds of monomers, such as terpolymers obtained from three kinds of monomers.

[0130] (13) Polyamines As the cationic polymer, it is also possible to use (co)polyamines, which may be homopolymers or copolymers, with a plurality of amino groups. The amino group may be a primary, secondary, tertiary or quaternary amino group. The amino group may be present in a polymer backbone or a pendent group, if present, of the (co)polyamines.

[0131] As examples of the (co)polyamines, mention may be made of chitosan, (co)polyallylamines, (co)polyvinylamines, (co)polyanilines, (co)polyvinylimidazoles, (co)polydimethylaminoethylenemethacrylates, (co)polyvinylpyridines such as (co)poly-l-methyl- 2-vinylpyridines, (co)polyimines such as (co)polyethyleneimines, (co)polypyridines such as (co)poly(quatemary pyridines), (co)polybiguanides such as (co)polyaminopropyl biguanides, (co)polylysines, (co)polyomithines, (co)polyarginines, (co)polyhistidines, aminodextrans, aminocelluloses, amino(co)polyvinylacetals, and salts thereof.

[0132] As the (co)polyamines, it is preferable to use chitosans. Chitosan is well known. Chitosan can be a linear polysaccharide composed of randomly distributed β-(1→ 4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). The actylation degree of chitosan may be from 1.0% to 10.0%, preferably from 2.0% to 8.0%, and more preferably from 3.0% to 6.0%. Chitosan can be prepared by, for example, treating the chitin shells of shrimp and other crustaceans with an alkaline substance, such as sodium hydroxide. Thus, the cationic polymer may be polyamines of polysaccharides, preferably linear polysaccharides.

[0133] As the (co)polyamines, it is preferable to use (co)polylysines. Polylysine is well known. Polylysine can be a natural homopolymer of L-lysine that can be produced by bacterial fermentation. For example, polylysine can be s-Poly-L-lysine, typically used as a natural preservative in food products. Polylysine is a polyelectrolyte which is soluble in polar solvents such as water. Polylysine is commercially available in various forms, such as poly D-lysine and poly L-lysine. Polylysine can be in salt and / or solution form.

[0134] (14) Cationic Polyamino acids

[0135] As the cationic polymer, it may be possible use cationic polyaminoacids, which may be cationic homopolymers or copolymers, with a plurality of amino groups and carboxyl groups. The amino group may be a primary, secondary, tertiary or quaternary amino group. The amino group may be present in a polymer backbone or a pendent group, if present, of the cationic polyaminoacids. The carboxyl group may be present in a pendent group, if present, of the cationic polyaminoacids.

[0138] The cationic polymer may be a polyquatemium polymer or a polymeric quaternary ammonium salt. Polymeric quaternary ammonium salts are cationic polymers comprising at least one quatemized nitrogen atom. Mention may in particular be made, as polymeric quaternary ammonium salts, of the Polyquatemium products (CTFA name), which contribute mainly to the quality of the foam and the feeling of the skin after use, in particular the feeling of the skin after use. These polymers can preferably be chosen from the following polymers: Polyquatemium-5, such as the product Merquat 5 sold by Nalco;

[0139] Polyquatemium-6, such as the product Salcare SC 30 sold by BASF and the product Merquat 100 sold by Nalco;

[0150] The amount of the (a) cationic polymer(s) in the composition according to the present invention may be 0.01% by weight or more, preferably 0.05% by weight or more, and more preferably 0.1% by weight or more, and / or may be 5% by weight or less, preferably 3% by weight or less, and more preferably 1% by weight or less, relative to the total weight of the composition.

[0151] The amount of the (a) cationic polymer(s) in the composition according to the present invention may range from 0.01% to 5% by weight, preferably from 0.05% to 3% by weight, and more preferably from 0.1% to 1% by weight, relative to the total weight of the composition.

[0152] (Hydrophilic Filler)

[0153] The composition according to the present invention comprises (b) at least one hydrophilic filler. Two or more hydrophilic fillers may be used in combination. Thus, a single type of hydrophilic filler or a combination of different types of hydrophilic fillers may be used.

[0154] The term “filler” should be understood here as meaning colorless or white, mineral or natural particles of any shape, which are insoluble in the medium of the composition, irrespective of the temperature at which the composition is manufactured.

[0155] The term "hydrophilic" here can mean that the material is readily dispersible in water at ambient conditions such as 25 °C and atmosphere pressure.

[0156] Thus, the term “hydrophilic filler” should be understood here as meaning fillers which are readily dispersible in water. In the present invention, although the (b) hydrophilic filler can be in the oily phase, the (b) hydrophilic filler maintains well dispersed and production of aggregation can be suppressed.

[0157] The (b) hydrophilic filler may be of any shape, platelet-shaped, spherical or oblong, irrespective of the crystallographic form (for example lamellar, cubic, hexagonal, orthorhombic, etc.).

[0158] The average particle size of the (b) hydrophilic filler is not limited, but in general is 50 μm or less, preferably 20 μm or less, and more preferably 15 μm or less. The average particle size of the (b) powder is 0.2 μm or more, preferably 0.5 μm or more, and more preferably 1 μm or more. Thus, the average particle size of the (b) hydrophilic filler may range from 0.2 μm to 50 μm, preferably from 0.5 μm to 20 μm, and more preferably from 1 μm to 15 μm.

[0159] The term “average particle size” used herein represents a number-average size mean diameter which is given by the statistical particle size distribution to half of the population, referred to as D50. For example, the number-average size mean diameter can be measured by a laser diffraction particle size distribution analyzer, such as Mastersizer 2000 by Malvern Corp.

[0160] The (b) hydrophilic filler can be an inorganic or organic filler, which may or may not be surface- coated.

[0161] As the inorganic filler, mention may be made of talc, mica, silica, silica silicate, magnesium aluminum silicate, kaolin, bentone, calcium carbonate, magnesium hydrogen carbonate, hydroxyapatite, boron nitride, fluorphlogopite, sericite, calcinated talc, calcinated mica, calcinated sericite, synthetic mica, perlite, lauroyl lysine, metal soap, bismuth oxychloride, barium sulfate, magnesium carbonate, and mixtures thereof, optionally hydrophilic- or hydrophobic-treated.

[0162] As the organic filler, mention may be made of natural polymer powders, such as polysaccharide powders and derivatives thereof, for example, starch, cellulose powder, and mixtures thereof.

[0163] In a preferred embodiment, the (b) hydrophilic filler is selected from silica, starch, cellulose powder, and mixtures thereof.

[0164] It would be important to mention that the (b) hydrophilic filler of the present invention is different from a so-called “inorganic UV filter”, such as titanium oxide. The (b) hydrophilic filler does not have an active, substantive UV filtering effect, while it can contribute to form a homogeneous and fine film on keratin materials, such as skin, by the composition according to the present invention. Therefore, the (b) hydrophilic filler of the present invention is not an inorganic UV filter, such as titanium oxide. Typically, inorganic UV filler is characterized by its fine particle size, and generally has less than 200 nm of average particle size.

[0165] The (b) hydrophilic filler may or may not be surface-coated. The coating may be an inorganic substance and / or an organic substance. In one embodiment of the present invention, the (b) hydrophilic filler is not surface-coated.

[0166] The inorganic coating may be selected from metal oxides, such as silica, aluminum oxides, titanium oxides, zirconium oxides, cerium oxide, chromium oxide, and iron oxides, and metal hydroxides, such as aluminum hydroxide.

[0167] The organic coating may be selected from fatty acids or salts thereof (such as sodium, potassium, zinc, iron or aluminum salts), fatty alcohols, lecithin, amino acids, polysaccharides, proteins, alkanolamines, waxes such as beeswax, (meth)acrylic polymers, and (per)fluoro compounds.

[0168] In one embodiment of the present invention, the (b) hydrophilic filler does not comprise synthetic coating which may cause the environmental problems in the same manner as microplastic fillers.

[0169] The (b) hydrophilic filler may be chosen from hydrophilic fillers which exhibit negative zeta potential in the medium or hydrophilic fillers whose surface is negatively charged in the medium.

[0170] The (b) hydrophilic filler can be selected from fillers other than microplastic fillers.

[0171] The term “microplastic filler” here means a synthetic polymer filler having an average particle size of 5 mm or less. The term “microplastic filler” here is also understood to mean polymeric solid particle insoluble in water which has size less than 5mm (all dimension) and stable throughout the life cycle.

[0172] The microplastic filler may include, but not limited to, acrylic polymer powders, silicone powders, wax powders, polyamide powders, urethane polymer powders, tetrafluoroethylene polymer powders, polyacrylonitrile powders, poly-β-alanine powders, polyethylene powders, polytetrafluoroethylene powders, lauroyllysine, tetrafluoroethylene polymer powders.

[0173] In one preferred embodiment of the present invention, the (b) hydrophilic filler comprises two or more type of hydrophilic fillers. In one specific embodiment, the (b) hydrophilic filler comprises at least one inorganic hydrophilic filler and at least one organic hydrophilic filler in combination.

[0174] The amount of the (b) hydrophilic filler(s) in the composition according to the present invention may be 1% by weight or more, preferably 3% by weight or more, more preferably 5% by weight or more, even more preferably 8% by weight or more, and in particular 10% by weight or more, and / or may be 30% by weight or less, preferably 25% by weight or less, more preferably 20% by weight or less, even more preferably 18% by weight or less, and in particular 15% by weight or less, relative to the total weight of the composition.

[0175] The amount of the (b) hydrophilic filler(s) in the composition according to the present invention may range from 1% to 30% by weight, preferably from 3% to 25% by weight, more preferably from 5% to 20% by weight, even more preferably from 8% to 18% by weight, and in particular from 10% to 15% by weight, relative to the total weight of the composition.

[0176] (Organically Modified Clay)

[0177] The composition according to the present invention comprises (c) at least one organically modified clay. Two or more types of organically modified clays may be used in combination. Thus, a single type of organically modified clay or a combination of different types of organically modified clays may be used.

[0178] Because the "organically modified clay" is intended to mean any clay that is modified with oraganic compounds, it represents liposoluble or lipodispersible property in the oily phase of the composition. Thus, the (c) organically modified clay may be present in the oily phase in the composition according to the present invention, and can be distinguished with the (b) hydrophilic filler which are readily dispersible in water.

[0179] The clay denotes a material based on hydrated silicates and / or aluminosilicates, of lamellar structure. The clay used in the (c) organically modified clay may include, for example, the smectite family, such as montmorillonites, hectorites, bentonites, beidellites and saponites, stevensite family and chlorite family. These clays may be of natural or synthetic origin.

[0180] The clay may be preferably selected from bentonites and hectorites.

[0181] The clay(s) may be modified with a compound chosen from quaternary ammonium salts, quaternary amines, tertiary amines, amine acetates, imidazolines, amine soaps, fatty sulfates, alkyl aryl sulfonates and amine oxides, and mixtures thereof.

[0192] The (d) oily medium(s) can constitute a fatty or an oily phase, which can be a continuous phase, in the composition according to the present invention.

[0193] The (d) oily medium may include oils and lipophilic solvents.

[0194] Here, “oil” means a fatty compound or substance which is in the form of a liquid, a paste (nonsolid), or a solid at room temperature (25°C) under atmospheric pressure (760 mmHg). As the oils, those generally used in cosmetics can be used alone or in combination thereof. These oils may be volatile or non-volatile. Preferably, the oil is in the form of a liquid or a paste (non-solid) at room temperature (25°C) under atmospheric pressure (760 mmHg).

[0195] The oil may be a non-polar oil such as a hydrocarbon oil, a silicone oil, or the like; a polar oil such as a plant or animal oil and an ester oil or an ether oil; or a mixture thereof.

[0325] EXAMPLES

[0326] The present invention will be described in more detail by way of examples which however should not be construed as limiting the scope of the present invention.

[0327] [Compositions]

[0328] Each of the W / O emulsion compositions according to Examples 1 to 3 (Ex. 1 to Ex. 3) and Comparative Examples 1 to 4 (Comp. Ex. 1 to Comp. Ex. 4) was prepared by mixing the ingredients listed in the following Table 1. Specifically, the W / O emulsion compositions were prepared by first mixing the ingredients of the “oily phase” and the ingredients of the “aqueous phase”, then adding “filler” ingredients and ethanol to the mixture, and then mixing it until it became homogenous. The numerical values in parentheses in the powder ingredients indicate average particle size of the powder ingredients. "Oily medium" in the tables indicate the (d) oily medium ingredients other that "Dimethicone". The numerical values for the amounts of the ingredients are all based on “% by weight” as active raw materials.

[0329] [Evaluation]

[0330] (Viscosity)

[0331] The viscosity of each of the compositions according to Examples 1-3 and Comparative Examples 1 -4 was measured with a B-type viscometer using rotor No. 4, at 6 rpm at room temperature (25 °C). The measurement was carried out for one minute.

[0332] (Stability)

[0333] The each of the obtained emulsion compositions in a beaker was kept at 25 °C for 5 days after they were manufactured. The appearance of each sample was then observed with the naked eye. The stability property was evaluated for each composition under the following criteria.

[0334] 1 : No phase separation was observed

[0335] 2: Slight phase separation was observed, but this is still well stable as a product

[0336] 3: Phase separation was clearly observed.

[0337] (Filler Aggregation)

[0338] The status of filler aggregation was observed with a microscope in the bulk of each of the emulsion compositions. The filler aggregation status was evaluated for each composition under the following criteria.

[0339] 1 : No filler aggregation was observed

[0340] 2: Slight filler aggregation was observed

[0341] 3: Filler aggregation was clearly observed.

[0342] (Permittivity) The permittivity of the bulk of each of the emulsion compositions was measured using a multi parameter meter (Orion™ Versa Star, Thermo Fisher Scientific) at ambient condition.

[0343] The results are shown in Table 2 below.

[0344] Table 1

[0345] Table 2 As can be seen from the evaluation results in Table 2, the W / O emulsion compositions according to Examples 1 to 3, which include the combination of the (a) cationic polymer having a molecular weight ranging from 20,000 to 500,000, the (b) hydrophilic filler, and the (c) organically modified clay showed low viscous property, good stability, as well as no filler aggregation even though they do not include microplastic fillers.

[0346] On the other hand, filler aggregation was observed in the compositions according to Comparative Examples 1 to 3, which do not include the (a) cationic polymer of the present invention.

[0347] Therefore, it can be concluded that the W / O emulsion composition according to the present invention is very preferable as a sun care cosmetic composition.
