Description

Technical Field

[0001] The present invention relates to cosmetics.

Background Art

[0002] Examples of cosmetics containing powder include makeup, sunscreen, concealer, makeup base, etc. When the powder aggregates, the color fades and a beautiful finish cannot be achieved, or the aggregates cause a resistant feel, and in the case of titanium oxide or zinc oxide as an ultraviolet scattering agent, it is known that the ultraviolet protection effect is reduced.

[0003] On the other hand, as the oil agents blended in cosmetics, hydrocarbon oils, higher fatty acids, higher alcohols, esters, polar oils such as organic ultraviolet absorbers, silicone oils, etc. are selected according to the purpose, but silicone oils, which are characterized by a light feel, are particularly often used. Therefore, many technologies regarding powder dispersants using modified silicones that are compatible with silicone oils have been developed so far. For example, a method using polyether-modified silicone as a dispersant (Patent Document 1) and a method using polyglycerin-modified silicone (Patent Document 2) have been proposed. These oil agents are often used in combination, but since their molecular weights and molecular polarities are different, the compatibility and feel between the combined oil agents are determined and used as cosmetics. Therefore, in order to improve compatibility with oil agents other than silicone, silicone compounds having both a long-chain alkyl group and a polyoxyalkylene group (Patent Document 3), silicone compounds having both a long-chain alkyl group and a polyhydric alcohol (Patent Document 4), etc., silicone compound parts having both a long-chain alkyl group, a glycerin group, and a branched silicone group (Patent Document 5) have been proposed. However, since the polyoxyalkylene group, polyhydric alcohol, and glycerin group have strong hydrophilicity and also act as surfactants, when used in emulsion cosmetics, depending on the combination with other surfactants, the dispersion stability and emulsion stability may be reduced.

[0004] In addition, carboxylic acid-modified silicone compounds (Patent Document 6) and carboxylic acid-modified silicone compounds with a molecular weight of 800 or less (Patent Document 7) have been proposed. Since carboxylic acids have weak emulsifying properties and good adsorption stability to powders, they are excellent as dispersants. However, in the prior art carboxylic acid-modified silicones, when a high content of powder is used, the cohesive force between the powders cannot be suppressed, and the viscosity of the dispersion increases. A dispersant forms a strong adsorption layer by adsorbing on the powder surface to suppress the re-aggregation of the powder. Therefore, it is important to have an organic group that can adsorb strongly, and there is a demand for a dispersant with even better dispersion stability.

In the present invention, the component names may be described by the cosmetic display name or the International Nomenclature of Cosmetic Ingredient (INCI). When the cosmetic display name and INCI correspond, the cosmetic display name or the English notation may be omitted.

[0011] [(A) Carboxylic acid-modified silicone] (A) The carboxylic acid-modified silicone is represented by the following formula (1) and can be used alone or in combination of two or more.

Chemical formula

[0012] R 1 is independently an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 15 carbon atoms, an aralkyl group having 7 to 15 carbon atoms, -Q-O-R 4 (Q is an alkylene group having 2 to 4 carbon atoms, R 4 is a monovalent organic group selected from (alkyl groups having 3 to 30 carbon atoms). Specifically, linear or branched alkyl groups such as methyl group, ethyl group, propyl group, butyl group, hexyl group, octyl group, decyl group, dodecyl group, tetradecyl group, hexadecyl group; cycloalkyl groups such as cyclopentyl group, cyclohexyl group; aryl groups such as phenyl group, tolyl group; aralkyl groups such as benzyl group, -C2H4OC 11 C 23 , -C2H4OC 12 C 25 , -C3H6OC 16 C 33 , -C3H6OC 18 C 37 , -C3H4OC 22 C 45Examples include the like. Among them, a methyl group is preferred. However, when the oil agent to be used contains polar oils such as hydrocarbon oils, higher fatty acids, higher alcohols, esters, and ultraviolet absorbers, a dodecyl group, a hexadecyl group, -C3H6OC 18 C 37 is also preferred.

[0013] R 2 is independently a carboxy group represented by the following formula (2) and is bonded via an ester bond.

Chemical formula

[0014] X is a hydrogen atom or a monovalent cation. Specific examples of the monovalent cation include alkali metal ions such as lithium, sodium, and potassium, and salts such as ammonium and alkylamines. Preferably, it is a hydrogen atom, sodium, or potassium. It is a carboxy group-containing monovalent organic group where n is 2 to 4, m is 2 to 4, L is 0 to 20, and p is 2 to 6. By being bonded via an ester bond, it is easily adsorbed on the surface of the powder particles, and a strong adsorption layer can be formed, thereby suppressing the aggregation of the powder particles and improving the dispersibility and dispersion stability of the powder. Specific examples include the following formulas (5) to (7).

[0015]

Chemical formula

Chemical formula

[0016] R 1Each is independently the same as above. h is from 0 to 5, and when obtained from the addition reaction of a vinylsiloxy group and a hydrosilyl group, h is 0. i is from 0 to 80, preferably from 1 to 10. i is from 0 to 80, preferably from 1 to 10. When i exceeds 80, the adsorption of the dispersant to the powder becomes poor and the dispersion stability deteriorates. j is from 0 to 3, preferably 0 or 1.

[0017] a is from 0 to 20, b is from 0 to 5, c is from 0 to 3, d is 0 or more, e is 0 or more, and f and g are numbers satisfying f + g = 2 + d + e×2. However, b and g do not become 0 at the same time. When a exceeds 20 or c exceeds 3, the adsorption of the dispersant to the powder becomes poor and the dispersion stability deteriorates. Also, when b exceeds 5, the polarity becomes high and the viscosity of the dispersant itself becomes high, resulting in deterioration of the dispersion stability. Since the compatibility varies depending on the type of oil agent used, these preferred values are different, but a is preferably from 0 to 10, b is preferably from 1 to 3, c is preferably from 0 to 3, d is preferably from 0 to 3, e is preferably from 0 to 3, and f + g is preferably from 2 to 11.

[0018] (A) The weight average molecular weight of the carboxylic acid-modified silicone is from 1,000 to 5,000, preferably from 1,000 to 3,000, considering the balance between the viscosity of the dispersant itself and the compatibility with the oil agent. If the weight average molecular weight is less than 1,000, the dispersion stability deteriorates over time. In the present invention, the molecular weight is the value of the weight average molecular weight by GPC (gel permeation chromatography) analysis using polystyrene as a standard substance under the following conditions.

[0019] (A) The compounding quantity of the component is 0.1 to 10 mass% in the cosmetic, and preferably 0.5 to 5 mass%. If it is less than 0.1 mass%, the dispersion stability of the powder will deteriorate, and if it is more than 10 mass%, the dispersant itself will have a sticky feeling.

[0020] (A) Carboxylic acid-modified silicone can be prepared according to a conventional method. The carboxylic acid-modified silicone of the present invention can be manufactured by known techniques. For example, it can be obtained by subjecting a hydrosilyl group-containing organopolysiloxane to an addition reaction with a terminal unsaturated group-containing hydroxyl compound and then subjecting it to a ring-opening reaction with succinic anhydride. More specifically, a manufacturing method having a step of reacting an organohydrogenpolysiloxane and a glycol having an unsaturated group in the presence of an addition reaction catalyst to obtain a hydroxyl group-containing dimethylpolysiloxane, and a step of subjecting this to a ring-opening reaction with an acid anhydride compound such as succinic anhydride can be mentioned.

[0085] [Chemical formula] For Comparative Structure 2, the carboxylic acid - modified silicone of the following formula (26) was used.

[0086] [Chemical formula]

[0087] [Evaluation of Dispersion Viscosity (Dispersibility)] The obtained dispersion was stored in a 100 - g glass bottle at 25 °C for 2 months. The viscosities of the dispersion immediately after preparation and after 2 months were measured at 25 °C using a B - type viscometer (TVB - 10 type, manufactured by Toki Sangyo Co., Ltd.) according to the method described in JIS K 7111 - 1:1999. The results are shown according to the following evaluation criteria. [Evaluation Criteria] ◎: 1,000 mPa·s or more and less than 2,000 mPa·s 〇: 2,000 mPa·s or more and less than 4,000 mPa·s △: 4,000 mPa·s or more and less than 10,000 mPa·s ×: 10,000 mPa·s or more, no fluidity

[0088] [Table 1]

[0089] [Table 2] Regarding *1 and *2 in Tables 1 and 2 *1: STR-100A-LP: Hydrated silica (designated name (HYDRATED SILICA)) / Aluminum hydroxide (designated name (ALMINUM HYDROXIDE)) Hydrogen dimethicone (designated name HYDROGEN DIMETHCONE) Treated titanium oxide (designated name TITANIUM OXIDE) *2: FINEX-30-LP is: Hydrated silica (designated name (HYDRATED SILICA)) / Hydrogen dimethicone (designated name HYDROGEN DIMETHCONE) Treated zinc oxide (designated name ZINC OXIDE)

[0090] As is clear from the above results, Examples 1 to 10 use silicone oil, and Examples 11 to 15 use ester oil, but all give dispersions with low viscosity (less than 4,000 mPa·s) and are found to have excellent stability over time. On the other hand, the dispersions obtained in Comparative Examples 1 to 6 were found to have high viscosity (4,000 mPa·s or more) immediately after preparation and to thicken over time. Thus, it was found that the carboxylic acid-modified silicone of the present invention has high dispersibility and can provide a low-viscosity dispersion with excellent storage stability.

[0091] The comparative structure 1 of the comparative example and the silicone of the comparative structure (24) formula have a structure in which a carboxylic acid is bonded to a silicon atom via a hydrocarbon group, but in the carboxylic acid-modified silicone of the present invention, a carboxy group is bonded to a silicon atom via an ester bond. Therefore, it is easy to adsorb on the surface of powder particles, can suppress aggregation between particles, and it was found that the powder has excellent dispersibility and dispersion stability.

[0092] [Examples 16 and 17, Comparative Examples 7 and 8] A cosmetic W / O foundation was prepared with the formulation shown in Table 3. (Manufacturing method) Components 1 to 7, 9 to 10 were mixed uniformly. After components 17 to 19 were uniformly mixed, they were gently added and stirred to obtain an emulsion. A mixture obtained by previously stirring and mixing components 8, 13 to 16, and component 12 were added to obtain a foundation.

[0093] The obtained cosmetics were evaluated according to the following evaluation criteria for (1) good elongation, (2) skin affinity, and (3) stability (over time). [Characteristic Evaluation] Regarding the cosmetics, 10 professional panelists evaluated the items of good elongation and color tone according to the following evaluation criteria. The results were judged according to the following judgment criteria based on the average value of the 10 panelists. [Evaluation Criteria] 5 points: Very good 4 points: Good 3 points: Normal 2 points: Slightly poor 1 point: Poor And the obtained average score was judged as ○× according to the following criteria. [Judgment Criteria] ◎: Average score is 4.5 points or more 〇: Average score is 3.5 points or more and less than 4.5 △: Average score is 2.5 points or more and less than 3.5 ×: Average score is 1.5 points or more and less than 2.5 ××: Average score is less than 1.5 points

[0094] [Stability (Over Time)] The cosmetics were filled into 30 mL vials and stored in a constant temperature bath at 50 °C for 1 week, and then the viscosity was measured. The change rate % of the viscosity after storage [(viscosity after storage - initial viscosity) / initial viscosity × 100] with respect to immediately after production (initial: temperature 25 °C) was determined. ◎: 0% or more and less than 25% 〇: 25% or more and less than 40% △: 40% or more and less than 50% ×: 50% or more or separates The viscosity measurement of this evaluation was carried out at 25 °C using a B-type viscometer (TVB-10 type, manufactured by Toki Sangyo Co., Ltd.). The range of the initial viscosity was in the range of 5,000 to 200,000 mPa·s.
