[Polyglycerin (PG)-Based Nonionic Surfactant: Component (B)]

[0034] A polyglycerin-based nonionic surfactant (nonionic surfactant) is a surfactant in which polyglycerin (PG) as a hydrophilic moiety and an alkyl group as a lipophilic moiety are bonded through an ether bond or an ester bond. The alkyl group preferably has 10 to 14 carbon atoms, and may be either a linear type or a branched type. Further, the alkyl chain may be either a saturated type or an unsaturated type. The polyglycerin (PG) refers to a trimer or higher order polymer of glycerin. In addition, the number of bonds between PG and an alkyl group is 1 (mono) to 3 (tri).

[0035] With respect to an HLB defined by the following formula, the polyglycerin-based nonionic surfactant preferably has an HLB in the range of 12 to 15.

HLB=(Molecular weight of hydrophilic moiety in surfactant/Molecular weight of surfactant)×20

[0036] Examples of an ester-type polyglycerin-based nonionic surfactant that is commonly available include PG(3) caprate (trade name: TEGOSOFT PC 31; Evonik Industries AG), PG(4) laurate (trade name: SY Glyster ML-310; Sakamoto Yakuhin Kogyo Co., Ltd.), PG(5) laurate (trade name: Sunsoft A-121E-C; Taiyo Kagaku Co., Ltd.), PG(6) laurate (trade name: SY Glyster ML-500; Sakamoto Yakuhin Kogyo Co., Ltd.), palm oil fatty acid PG(3) (trade name: EMALEX MCCG-3; Nihon Emulsion Co., Ltd.), PG(5) myristate (trade name: Sunsoft A-141E-C; Taiyo Kagaku Co., Ltd.), PG(6) myristate (trade name: NIKKOL Hexaglyn 1-M; Nikko Chemicals Co., Ltd.), PG(10) dimyristate (trade name: Sunsoft Q-142Y-C; Taiyo Kagaku Co., Ltd.), and the like.

For example, in the notation such as PG(3) caprate, the numerical value in the parentheses, that is, “3” represents the number of moles of added polyglycerin.

[Glycerin: Component (C)]

[0037] The glycerin may be any as long as it can be used in a cosmetic, and includes synthetic glycerin produced by a synthesis method and natural glycerin produced by saponifying a naturally derived fat or oil. Since glycerin has a very high viscosity and is difficult to handle, there are those diluted with purified water to a concentration of 84% to 87% and those having a concentration of 95% or more. Examples of a commonly available product include 85% glycerin for cosmetics, concentrated glycerin for cosmetics (95% or more of glycerin), Japanese Pharmacopoeia glycerin, Japanese Pharmacopoeia concentrated glycerin, and the like. Among these, preferred glycerin is concentrated glycerin having a glycerin concentration of 95% or more. Glycerin is a main solvent for dispersing the hydrophobic powder, but a dimer or a trimer of glycerin may be mixed or replaced within a range that does not impair the dispersibility and fluidity of the hydrophobic powder. Examples thereof include diglycerin and triglycerin. When a dispersion is formed by mixing another aqueous component that can be dissolved in glycerin, for example, a component such as butylene glycol, pentylene glycol, hexylene glycol, or water in glycerin, the dispersibility of the hydrophobic powder deteriorates and also the viscosity of the dispersion increases.

[0038] The blending ratio of the glycerin dispersion is as follows: (A) hydrophobic organic surface treatment agent-coated inorganic powder/(B) hydrophilic polyglycerin-based nonionic surfactant having 10 to 14 carbon atoms/(C) glycerin=50.0 or more/10.0 or less/to 100.0 (wt %). It is preferably 50.0 or more/7.5 or less/to 100.0 (wt %), and more preferably 50.0 or more/less than 5.0/to 100.0 (wt %). The safety of the polyglycerin-based surfactant is relatively high, but when the surfactant having a molecular weight of 1000 or less is blended, the blending amount is preferably as small as possible from the viewpoint of irritation to the skin.

[0039] In the glycerin dispersion, a thickener, an antioxidant, an antibacterial preservative, a chelating agent, a pigment dispersant, a sensation improving agent, or the like can be appropriately blended as needed.

[0040] A method for producing the glycerin dispersion is not particularly limited, and the production may be performed by mixing the above-mentioned components. The mixing method is also not limited, and a usual method that enables uniform dispersion may be adopted. For example, an apparatus such as a disperser/kneader such as a ball mill, a bead mill, a wet jet mill, a homogenizer, a high-pressure homogenizer, a single-screw kneader, a twin-screw kneader, or a three-roll mill can be used.

[0041] By blending the glycerin dispersion in a cosmetic, a cosmetic having excellent sense of use, cosmetic finish, and cosmetic durability is provided.

[0042] In the cosmetic, the glycerin dispersion composition of the present invention can be blended in an amount of 0.1 wt % or more with respect to the total cosmetic, although it varies depending on the type and dosage form of the cosmetic. As the cosmetic in which the hydrophobized inorganic powder is blended, as a makeup cosmetic, a makeup base, a powder foundation, a liquid foundation, an oily foundation, a stick foundation, a pressed powder, a face powder, a white powder, a lipstick, a lipstick overcoat, a lip gloss, a concealer, a cheek color, an eye shadow, an eyebrow, an eyeliner, a mascara, an aqueous nail enamel, an oily nail enamel, an emulsion nail enamel, an enamel top coat, an enamel base coat, and the like, as a skin care cosmetic, an emollient cream, a cold cream, a whitening cream, a milky lotion, a toner lotion, a beauty essence serum, a facial pack, a carmine lotion, a liquid face wash, a face wash foam, a face wash cream, a face wash powder, a makeup cleansing, a body gloss, a sunscreen or suntan cream or lotion, and the like, as a hair cosmetic, a hair gloss, a hair cream, a hair shampoo, a hair rinse, a hair color, a hair brushing agent, and the like, as an antiperspirant, cream, lotion, powder, and spray-type deodorant products, and the like, as other cosmetics, a milky lotion, a soap, a bathing agent, a perfume, and the like can be exemplified.

[0043] Further, in the cosmetic, a pigment dispersant, an oil agent, a surfactant, a UV absorber, a preservative, an antioxidant, a film forming agent, a moisturizer, a thickener, a dye, a pigment, various chemicals, a fragrance, or the like, to be used for ordinary cosmetics or the like can be appropriately blended.

[0044] The glycerin dispersion is useful for blending the hydrophobic powder in the aqueous layer of a cosmetic. In the case of a powder-type cosmetic, almost no aqueous component is blended, but by blending glycerin, which is a moisturizer, the hydrophobic powder can be blended in the aqueous layer of the cosmetic. Further, in an emulsion-type cosmetic or an aqueous cosmetic, by blending the glycerin dispersion composition of the present invention in an aqueous layer component, it is possible to adjust the colorability and gloss, and impart a UV shielding function.

[Viscosity, Dispersibility, and Stability Over Time of Glycerin Dispersion]

[0083] With respect to the glycerin dispersions of Examples 1 to 22 and Comparative Examples 1 to 13, the viscosity, dispersibility, and stability over time were evaluated.

(Evaluation of Viscosity)

[0084] With respect to the glycerin dispersion immediately after production, the viscosity was measured using a BH type rotational viscometer (Brookfield, Inc.) under the conditions of 25° C. using No. 4 rotor at 1.5 rpm/60 sec and 3 rpm/60 sec (4V1.5/4V3).

(Evaluation of Dispersibility)

[0085] 5.0 g of the glycerin dispersion was taken in a 200 cc glass beaker, and ion exchanged water was added thereto until the total amount reached 100 g. The mixed liquid was dispersed with a disper mixer at 1400 rpm/minute. 1 g of the dispersion liquid was taken with a dropper and dropped in the middle of a qualitative filter paper No. 2 (150 mm φ: Advantech Co., Ltd.) and soaked in the filter paper. After 1 minute, it was evaluated whether or not a grain was observed on the filter paper. The opening of the qualitative filter paper No. 2 is about 10 μm. The evaluation criteria are shown below.

O: No grains are observed.
x: A grain is observed.

(Stability Test Over Time)

[0086] In a 100 mL wide mouth bottle (made of PP, trade name: Iboy), 150 g of the glycerin dispersion was placed, and the bottle was covered with a lid, thereby preparing a sample. The sample was placed in a thermostat bath at 50° C. for 2 weeks, then taken out and left at normal temperature for 1 day, and the appearance and properties of the sample thereafter were evaluated. With respect to the appearance, it was evaluated whether or not liquid separation occurred and whether or not a precipitate was formed on the bottom of the bottle by visual observation. With respect to the properties, a precipitate was touched with a spatula and it was evaluated whether or not the precipitate was hardened and caked. The evaluation criteria are shown below.

O: Liquid separation or precipitation is not observed.
x: Liquid separation is observed in the upper layer. Alternatively, a precipitate is hardened and caked.

[0087] In the following Table 2, the evaluation results of the viscosity, dispersibility, and stability over time of the glycerin dispersions of Examples 1 to 22 and Comparative Examples 1 to 13 are shown.

(Discussion of Evaluation Results)

[0088] From the evaluation results of Example 1 (dispersion medium: glycerin), Example 22 (dispersion medium: diglycerin), and Comparative Example 8 (dispersion medium: butylene glycol), it was found that when glycerin or diglycerin was used as the dispersion medium, the viscosity, dispersibility, and stability over time are excellent as compared with the case where butylene glycol was used as the dispersion medium.

[0089] In addition, excellent viscosity, dispersibility, and stability over time are achieved also in Examples 1 to 4, 9 to 12, 14, 16, and 22 (PG(5) myristate: 14 carbon atoms), Examples 5 to 8 (PG(4) lauryl ether: 12 carbon atoms), Example 13 (PG(5) laurate: 12 carbon atoms), Example 15 (PG(3) caprate: 10 carbon atoms), and Examples 19 to 21 (palm oil fatty acid PG(3): 8 to 18 carbon atoms, mainly composed of 12 carbon atoms), and therefore, it was found that the alkyl group in the PG-based nonionic surfactant preferably has 10 to 14 carbon atoms. Further, from the evaluation results of Example 17 (the number of attached alkyl groups: 2) and Example 18 (the number of attached alkyl groups: 3), excellent viscosity, dispersibility, and stability over time are achieved regardless of the number of attached alkyl groups.

[0090] On the other hand, from Comparative Example 1 (PG(10) palmitate: 16 carbon atoms), Comparative Example 2 (PG(10) isostearate: 18 carbon atoms), and the like, in the case where the alkyl group in the PG-based nonionic surfactant has 16 or more carbon atoms, the viscosity, dispersibility, and stability over time were poor as compared with the case where the alkyl group has 10 to 14 carbon atoms.

[0091] It was also found that as in Examples 1, and 15 to 22, in the glycerin dispersion of the present invention, the hydrophobized inorganic powder could be blended at a high concentration, in particular, in an amount of 50 wt % or more.

[0092] Further, the glycerin dispersions of Examples 1 to 22 were flowing highly viscous liquids, whereas the glycerin dispersions of Comparative Examples 1 to 13 were in a solid form. That is, the glycerin dispersions of Examples 1 to 22 were sticky liquids, but had better handleability than the glycerin dispersions of Comparative Examples 1 to 13 in a solid form obtained by blending a hydrophobized powder at a high concentration.

[Cosmetic Obtained by Blending Glycerin Dispersion]

[0093] Next, the following cosmetics were prepared and evaluated for the sense of use, cosmetic effect, and cosmetic durability. The sense of use, cosmetic effect, and cosmetic durability were evaluated based on the average of scores given by 25 expert panelists who were asked to use each cosmetic for one day and score on a five-point scale shown below. The sense of use is evaluated in terms of good smoothness, no stickiness, and comfort. Further, the cosmetic effect is evaluated in terms of powderiness, no uneven coating, uniformity of the cosmetic film, and natural luster. Further, the cosmetic durability is evaluated in terms of occurrence of color dullness or shininess with the passage of time, and no powder aggregation.
