Description

Article 30, Paragraph 2 of the Patent Act applies Exhibition date: January 20, 2020 (January 20, 2020 - January 22, 2020) Exhibition name, venue 10th Cosmetic Development Exhibition (Makuhari Messe, 2-1 Nakase, Mihama-ku, Chiba City)

The present invention relates to a lotion, and particularly to a lotion with improved stability of oil droplets over time and further improved moisturizing properties after use.

Cosmetics have conventionally contained a wide variety of water-based and oil-based ingredients for the purpose of moisturizing the skin and replenishing moisture and oil. However, since water and oil have a large difference in surface tension, there is a problem that they do not mix and separate. Therefore, various methods are being considered for mixing the aqueous component and the oil component.

As such a method, for example, Patent Document 1 discloses a composition in the form of an oil-in-water emulsion, comprising: a) a dispersed fatty phase containing at least one oil selected from silicone oils, hydrocarbonated oils, or mixtures thereof; b) a continuous aqueous phase containing at least one C ₁ -C ₄ alcohol having at least one hydroxyl group, which is linear or branched, saturated or unsaturated, in an amount ranging from 0.1% by weight to 20% by weight relative to the total weight of the composition; c) at least one hydrophobic particle selected from hydrophobic silica, hydrophobic cellulose, starch, talc, silicone resin powder, hollow hemispherical silicone particles, polyamide powder, hydrophobic pigments, or mixtures thereof; and d) at least one polysaccharide. Patent Document 2 discloses a W/O/W type composite emulsion comprising (A) one or more water-soluble film-forming polymers selected from the group consisting of gum arabic, alginic acid and salts thereof, carrageenan, agar, guar gum, quince seed, tamarind gum, dextrin, dextran, starch, locust bean gum, karaya gum, tragacanth gum, pectin, quince, chitosan, xanthan gum, gellan gum, hyaluronic acid and salts thereof, pullulan, methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, carboxymethylcellulose, cationized cellulose, polyacrylic acid amide, polyvinyl alcohol, and polyvinylpyrrolidone, and (B) a silicone oil, and having a viscosity at 30° C. in the range of 3,000 to 15,000 mPa·s.

Furthermore, Patent Document 3 discloses a cosmetic composition that contains polyglycerin having an average degree of polymerization of 10 to 30, polyglycerin fatty acid ester (A) in which a mixed fatty acid of caprylic acid and capric acid is ester-bonded, oil (B), and 30 to 88 mass % of water (C), and the blending ratio of polyglycerin fatty acid ester (A) to oil (B) is 6:1 to 2:1. Furthermore, Patent Document 4 discloses a cosmetic composition that is transparent and essentially alcohol-free, and contains at least one chemical ultraviolet (UV) ray absorber; at least one solvent selected from the group consisting of dimethicone, dicaprylyl carbonate, lauryl lactate, neopentyl glycol diheptanoate, glycerin, and combinations thereof; and at least one diphenyl silicone elastomer gelling agent including diphenylsiloxyphenyl trimethicone.

However, since the techniques described in Patent Document 1 and Patent Document 2 are emulsions, coalescence of oil droplets over time cannot be avoided, and sufficient stability over time of oil droplets cannot be obtained.

In addition, Patent Document 3 requires a surfactant such as a polyglycerol fatty acid ester, and Patent Document 4 requires a diphenyl silicone elastomer gelling agent, so although a transparent lotion can be obtained, the surfactant and diphenyl silicone elastomer gelling agent do not provide a sufficient moisturizing feeling after use.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a lotion that solves the problems of the prior art described above, has improved stability of oil droplets over time, and has improved moisturizing properties after use.

The present inventors have conducted extensive studies to solve the above problems, and have discovered that the above objects can be achieved by combining an oily component with a specific polymer and by limiting the blending amount, and have devised the present invention. It was completed.

That is, the lotion of the present invention contains 0.5 to 5 mass % of an oily component (A),
(B) 0.05 to 0.3% by mass of gellan gum;
(C) 0.05 to 0.3 mass% of one or more selected from the group consisting of hydroxyethyl cellulose and xanthan gum,
The present invention is characterized in that it contains:

The lotion of the present invention preferably further contains (D) a calcium compound and/or a magnesium compound, and preferably contains (E) one or more selected from the group consisting of polyhydric alcohols and ethanol, and further preferably contains (F) one or more selected from the group consisting of organic acids selected from the group consisting of citric acid, malic acid, ascorbic acid, ferulic acid, tranexamic acid, oxalic acid, malonic acid, succinic anhydride, glutaric acid, adipic acid, fumaric acid, maleic anhydride, phthalic acid, isophthalic acid, terephthalic acid, and glutamic acid, and alkali metal salts of the organic acids.

In addition, in the lotion of the present invention, the oily component (A) is one selected from the group consisting of phenyl trimethicone, diphenylsiloxyphenyl trimethicone, diphenyl dimethicone, trimethylsiloxyphenyl dimethicone, and trimethylpentaphenyltrisiloxane; It is preferable that there are two or more types, and it is particularly preferable that the oily component (A) is diphenylsiloxyphenyl trimethicone.

Furthermore, in the lotion of the present invention, the component (C) is preferably hydroxyethyl cellulose.

According to the present invention, it is possible to provide a lotion with improved stability of oil droplets over time and improved moisturizing properties after use.

Hereinafter, the lotion of the present invention will be specifically explained.
The lotion of the present invention is selected from the group consisting of (A) 0.5 to 5% by mass of an oily component, (B) 0.05 to 0.3% by mass of gellan gum, and (C) hydroxyethylcellulose and xanthan gum. It is characterized by containing 0.05 to 0.3% by mass of one or more of the following. The lotion of the present invention is a lotion that has improved dispersion (including dissolution and solubilization) stability of oil droplets over time, and is a transparent lotion that has the effect of improving moisturizing properties after use. By reducing the amount of oil and creating larger gaps between oil droplets than before, it is possible to emphasize the appearance of floating oil droplets.In order to increase the transparency of the water phase, many polymers and thickeners are used. A transparent lotion can be obtained by combining gellan gum with hydroxyethylcellulose and/or xanthan gum. Therefore, polymers and thickeners such as carbomer, acrylic acid/alkyl methacrylate copolymer, (acryloyldimethyltaurate ammonium/VP) copolymer are poor in stability, and the effects of the present invention cannot be obtained. In addition, conventionally, oil droplets were created by increasing the amount of oil-based ingredients blended, but because of the large number of oil droplets, the appearance was not good, and the feeling of use was too oily, making it unsatisfactory as a lotion. In contrast, in the present invention, by adjusting the blending amount, a transparent lotion with a transparent appearance and good moisturizing effect can be obtained. Furthermore, in the present invention, a transparent lotion containing an oily component (silicone oil) can be obtained without incorporating a surfactant.

The lotions of Examples A to C were prepared using the blending amounts (contents) shown in Table 6 below. The obtained lotions were tested for the above-mentioned "appearance (interval between oil droplets)" and "transparency of the aqueous phase", and the results are shown in Figure 1.

Fig. 1 is a photograph showing the "appearance (spacing between oil droplets)" and "transparency of the aqueous phase" of Examples A to C, and Fig. 2 is a photograph showing examples of poor "appearance (spacing between oil droplets)" and "transparency of the aqueous phase". As shown in Fig. 1, the lotions of Examples A to C were in a good condition, showing "○: the intervals between the oil droplets are large and the appearance emphasizes the oil droplets" in the above "appearance (spacing between oil droplets) test" and "◎: highly transparent" in the "aqueous phase transparency test". For reference, Fig. 2 also shows the above "appearance (spacing between oil droplets) test" and "×: poor appearance, small intervals between oil droplets and too many oil droplets, not an appearance where the oil droplets are emphasized" and "×: opaque" in the "aqueous phase transparency test".
