Abstract

Provided are: an activator composition containing (A) a nonionic surfactant that has two or more hydroxyl groups per hydrophilic group, and (B) an oily component that is in a liquid form at 25°C and has only one hydroxyl group, the viscosity at 25°C of said activator composition being lower than 50% of the viscosity of component (A) and said activator composition having low viscosity and excellent handling properties; and a cosmetic containing the activator composition and giving good feeling in use.

Description

Technical Field

[0001] The present invention relates to an activator composition and a cosmetic containing the same.

Background Art

[0002] Generally, nonionic surfactants used in cosmetics are surfactants having a hydrophilic group that does not dissociate into ions in their molecules. As the hydrophilic group, a polyoxyethylene chain or a polyhydric alcohol chain is generally widely used.

[0003] Nonionic surfactants having a polyhydric alcohol chain represented by glycerin are widely used as emulsifiers, solubilizers, etc. because of their excellent safety and functions. For example, Patent Document 1 discloses a low-viscosity emulsion W / O type emulsifying cosmetic having excellent usability and good long-term stability. This emulsifying cosmetic is characterized by containing one or more kinds of polyglycerol fatty acid esters, glycerin, an oil-based agent, and water.

[0004] In addition, silicone-based surfactants modified with glycerin or polyglycerol are known to have excellent moisturizing performance (Patent Document 2). Also, a technique for improving the formulation stability by improving the dispersibility of hydrophobically treated powder (Patent Document 3) is also known. A technique for improving the formulation stability by using a glycerin-modified silicone-based surfactant and trimethylsiloxysilicic acid in combination is also known (Patent Document 4).

[0005] However, nonionic surfactants having a polyhydric alcohol chain having two or more hydroxyl groups as a hydrophilic group, such as glycerin, are difficult to handle because of their high viscosity. In particular, there were limitations in the development of high molecular weight substances.

[0010] According to the present invention, it is possible to reduce the viscosity of a nonionic surfactant having two or more hydroxyl groups per hydrophilic group, thereby providing an surfactant composition with excellent handling properties, and a cosmetic composition containing this surfactant with a pleasant feel. [Modes for carrying out the invention]

[0011] The present invention will be described in detail below. In this invention, ingredient names may be described using cosmetic names or International Nomenclature of Cosmetic Ingredient (INCI). If the cosmetic name and INCI correspond, the English description may be omitted.

[0012] [(A) component] Component (A) of the present invention is a nonionic surfactant having two or more hydroxyl groups per hydrophilic group, and can be used alone or in combination of two or more. The hydrophilic group of component (A) is not limited as long as it is one that is generally used in nonionic surfactants. Examples include those containing the structure of polyhydric alcohols such as glycerin, trimethylolpropane, pentaerythritol, sorbitan, sorbitol, sucrose, polyglycerin, and raffinose sugar. Furthermore, some of the hydroxyl groups of these hydrophilic groups may be modified, and these hydrophilic groups may be used alone or in combination of two or more. Among these, hydrophilic groups having the structure of glycerin or polyglycerin are preferred in terms of emulsifying properties, dispersibility, and moisturizing properties.

[0013] The number of hydroxyl groups in component (A) is two or more per hydrophilic group. The more hydroxyl groups there are, the more pronounced the effects of the present invention become. However, in terms of balance with hydrophobic groups, 3 to 20 is preferable, 3 to 15 is more preferable, and 4 to 10 is even preferable.

[0014] (A) Examples of component (A) include fatty acid ester surfactants of polyhydric alcohols such as sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, glycerin fatty acid ester, polyoxyethylene glycerin fatty acid ester, and polyglycerin fatty acid ester, as well as silicone surfactants such as polyglycerin-modified silicone (organopolysiloxane). Among these, silicone surfactants are preferred because they have less influence on viscosity due to hydrophobic groups and the effects of the present invention are clearly expressed, and polyglycerin-modified silicone is more preferred.

[0015] Examples of ester-based surfactants include polyglyceryl-2 isostearate, polyglyceryl-10 laurate, polyhydroxystearic acid, sorbitan stearate, and sorbitan sesquiisostearate.

[0016] The silicone-based surfactant may be either linear or branched. Specifically, examples include partially crosslinked polyglycerol-modified silicone, linear or branched polyglycerol-modified organopolysiloxane, and linear or branched polyglycerol-alkyl co-modified organopolysiloxane. Among them, those having a linear or branched organopolysiloxane as the main skeleton and a polyglycerol chain in the side chain, or those having a linear or branched organopolysiloxane as the main skeleton and both a polyglycerol chain and an alkyl chain in the side chain can be most preferably used in terms of the feeling of use and emulsification performance.

[0017] Examples of the partially crosslinked polyglycerol-modified silicone include (dimethicone / polyglycerin-3) crosspolymer (INCI), (lauryldimethicone / polyglycerin-3) crosspolymer (INCI), (polyglycerin-3 / laurylpolydimethylsiloxyethyl dimethicone) crosspolymer (INCI), etc. The partially crosslinked polyglycerol-modified silicone may be a composition comprising the partially crosslinked polyglycerol-modified silicone and an oil agent that is liquid at room temperature. Examples of the liquid oil agent include cyclopentasiloxane (INCI), dimethicone (INCI), mineral oil (INCI), isododecane (INCI), triethylhexanoin (INCI), squalane (INCI), etc.

Examples of commercially available products include KF-6100, KF-6104, KF-6105, KF-6106, KF-6115, etc. manufactured by Shin-Etsu Chemical Co., Ltd. Since the partially crosslinked polyglycerin-modified silicone has a thickening effect due to the crosslinked portion in its structure, the viscosity-reducing effect with the component (B) of the present invention is not remarkable. The polyglycerin-modified silicone is preferably linear or branched.

[0020] The viscosity of the component (A) at 25°C is preferably selected from the range of, for example, 100 to 500,000 mPa·s, more preferably 1,000 to 400,000 mPa·s, and even more preferably 3,000 to 500,000 mPa·s. According to the present invention, even with the component (A) having such a viscosity, viscosity reduction is possible. In the present invention, the viscosity is the value at 25°C measured by the method using a B-type rotational viscometer described in JIS K7117-1:1999 (hereinafter the same).

[0021] [Component (B)] The component (B) of the present invention is an oily component that is liquid at 25°C and has one hydroxyl group. Among them, components with a solubility of less than 1 g in 100 g of purified water at 25°C are preferred. Regardless of the number of hydroxyl groups in the component (A), oil agents without hydroxyl groups and oil agents with two or more hydroxyl groups are not included in the component (B). Also, lower alcohols having 1 to 5 carbon atoms, which have high hydrophilicity and may deteriorate the affinity for the oil layer, are not included in the component (B).

[0022] (B) Examples of components include higher alcohols, higher fatty acids, and ester oils that are liquid at 25°C. Among these, higher alcohols such as aliphatic alcohols and ester oils are preferred, and branched-chain aliphatic alcohols with 16 to 24 carbon atoms are most preferred in terms of usability and low viscosity. These can be used individually or in appropriate combinations of two or more.

[0023] Examples of higher alcohols include alcohols with 6 or more carbon atoms, preferably with 16 to 24 carbon atoms, more preferably with 16 to 20 carbon atoms, and particularly preferably with 16 to 18 carbon atoms in terms of compatibility with component (A) and usability. Specific examples of higher alcohols include lauryl alcohol (INCI), hexyldecanol (INCI), oleyl alcohol (INCI), isostearyl alcohol (INCI), octyldodecanol (INCI), decyltetradecanol (INCI), and the like.

[0024] Examples of higher fatty acids include fatty acids with 6 or more carbon atoms, preferably with 16 to 24 carbon atoms, and more preferably with 16 to 20 carbon atoms. Examples include oleic acid (INCI: Oleic Acid), linoleic acid (INCI: Linoleic Acid), linolenic acid (INCI: Linolenic Acid), arachidonic acid (INCI: Arachidonic Acid), eicosapentaenoic acid (INCI: Eicosapentaenoic Acid), docosahexaenoic acid (INCI: Docosahexaenoic Acid), isostearic acid (INCI: Isostearic Acid), etc.

[0025] Examples of ester oils include diisostearyl malate (INCI: Diisostearyl Malate), triethyl citrate (INCI: Triethyl Citrate), cetyl lactate (INCI: Cetyl Lactate), myristyl lactate (INCI: Myristyl Lactate), cholesteryl hydroxystearate (INCI: Cholesteryl Hydroxystearate), butylene glycol cocoate (INCI: Butylene Glycol Cocoate), polyglyceryl-2 triisostearate (INCI: Polyglyceryl-2 Triisostearate), homosalate (INCI), and ethylhexyl salicylate (INCI: Ethylhexyl Salicylate).

[0026] The present invention reduces the viscosity of component (A) by combining it with component (B), and the viscosity of component (B) at 25°C is not limited as long as it is liquid at 25°C. For example, it is preferably selected from the range of 1 to 3,000 mPa·s, more preferably from 5 to 400 mPa·s, and even more preferably from 30 to 60 mPa·s.

[0027] The composition ratio of component (A) to component (B) is 70:30 by mass. 98 : 2 It is preferable that the range be 80:20~ 95 : 5More preferably, 85:15 to 95:5 is preferred. When the total is 100, if the mass ratio of (A) exceeds 95, the viscosity may not be sufficiently low, and if the mass ratio of (B) exceeds 30, the function of the activator may not be sufficiently obtained. In the activator composition, the total amount of component (A) and component (B) may be 15% by mass or more, but it is preferably 90% by mass or more, more preferably 95% by mass or more, even more preferably 99% by mass or more, and particularly preferably 100% by mass. By setting the total amount of component (A) and component (B) to 90% by mass or more, the mixability (ease of weighing) in the oil phase during cosmetic preparation is further improved. The activator composition of the present invention is formulated by pre-mixing component (A) and component (B) and incorporating them into the cosmetic formulation, making it a low-viscosity activator with excellent handling properties, thus facilitating weighing and addition. Therefore, it is not an unintentional mixing in the formulation.

[0028] The components other than components (A) and (B) in the surfactant composition are components that are normally incorporated into cosmetics and are not particularly limited as long as they are components and amounts that fall within a predetermined viscosity range. Examples include surfactants other than component (A), such as polyether-modified silicones, pyrrolidone carboxylic acid-modified silicones, and ionic surfactants; oils other than component (B), such as silicone oils, hydrocarbon oils, and ester oils; aqueous components; powders; and so on.

[0029] The viscosity of the mixture of component (A) and component (B), and the activator composition at 25°C is less than 50% of the viscosity of component (A), preferably less than 40%, more preferably less than 30%, and even more preferably less than 25%. In the present invention, component (A) can be made even more viscous, and the viscosity of the mixture and the activator composition at 25°C is preferably 100 to 50,000 mPa·s, more preferably 500 to 15,000 mPa·s, and even more preferably 500 to 5,000 mPa·s. Such a viscosity makes handling easy, and weighing and mixing easy. As mentioned above, viscosity is the value at 25°C measured using the method described in JIS K7117-1:1999 using a type B rotational viscometer.

[0030] Furthermore, the activator composition of the present invention is preferably a composition that can be uniformly mixed. Specifically, it is a composition that does not separate under conditions of 25°C after mixing, and a composition that becomes cloudy is undesirable. A semi-transparent dissolution is preferred, and a transparent dissolution is even more preferred from the standpoint of quality control. Transparency is determined by measuring the total light transmittance of 50% or more when filled into a 1 cm thick cell according to the method described in JIS K7361-1:1997, with a total light transmittance of 80% or more being judged as semi-transparent. Furthermore, from the viewpoint of transparency, the following combinations are preferred: (A) component is polyglyceryl-3 polydimethylsiloxyethyl dimethicone and (B) component is a higher alcohol having 16 to 18 carbon atoms; (A) component is lauryl polyglyceryl-3 polydimethylsiloxyethyl dimethicone and (B) component is a higher alcohol having 16 to 24 carbon atoms; (A) component is polyglyceryl-3 disiloxane dimethicone and (B) component is a higher alcohol having 16 to 18 carbon atoms; and (A) component is polyglyceryl-10 laurate and (B) component is a higher alcohol having 16 to 18 carbon atoms.

In this case, the amount of activator composition is preferably in the range of 0.1 to 40% by mass of the total cosmetic, and especially when used as an emulsifier in the preparation of emulsions, it is preferably 0.1 to 8% by mass of the total cosmetic, and more preferably 0.1 to 5% by mass. When calculated as the total amount of component (A) and component (B), it is preferably 0.1 to 8% by mass of the total cosmetic, and more preferably 0.1 to 5% by mass.

In particular, as is clear from the results of Examples 6 to 8, the effect is not simply due to the viscosity of component (B). From Examples 1 to 5, the viscosity reduction rate was more pronounced when component (A) was polyglycerin-modified silicone and component (B) was branched-chain saturated alcohol. Furthermore, from Comparative Examples 1 to 9, the viscosity reduction rate was insufficient when using silicone hydrocarbon oils commonly used in combination with component (A), ester oils with a viscosity similar to that of component (B), or mixtures with different components of (A). Comparative Example 10, in which there is one hydroxyl group per hydrophilic group of the activator, did not show sufficient viscosity reduction even when combined with component (B). From these results, it was found that the combination of components (A) and (B) is important for viscosity reduction.

[0097] [Examples, Comparative Examples (Cosmetics)] Water-in-oil (W / O) formulations were prepared using the formulations shown in Table 4. (Manufacturing method) A: Mixed ingredient (1). B: Component (2) was mixed. C: The mixture obtained in A was emulsified by adding the mixture obtained in B to obtain a water-in-oil (W / O) cream.

[0098] [Characteristic evaluation] Ten expert panelists evaluated the mixability of the oil phase during cosmetic preparation (ease of weighing) and the feel of the cosmetic (spreadability) according to the evaluation criteria below. The results were judged based on the average of the ten panelists' evaluations, according to the judgment criteria below. The results are shown in the table.

[0099] [Evaluation Criteria] 5 points: very good 4 points: Good 3 points: Average 2 points: Slightly poor 1 point: Defective The resulting average score was then judged as either ○ or × according to the following criteria. [Judgment criteria] ◎: Average score of 4.5 points or higher ○: Average score is between 3.5 and 4.5 points. △: Average score is between 2.5 and 3.5 points. ×: Average score is between 1.5 and 2.5 points. ××: Average score is less than 1.5 points A score of "△" or higher was considered a passing grade.

[0101] As is clear from Table 4, the cosmetics of Examples 13-16 had a good feel when used, and in particular, Examples 13 and 14 had good mixability and were easy to prepare. The viscosity of the mixture of (1) in Examples 15 and 16 at 25°C was less than 50% of the viscosity of component (A) (3,392 mPa·s).
