[0008] The aqueous cosmetic preparation of the present invention contains the following components (A) to (C). (A) Tocopheryl phosphate (B) Alanylglutamine and / or hydroxyproline (C) Sclerotium gum

[0009] (A) Ingredient: Tocopheryl phosphate Tocopheryl phosphate is a derivative of the chemically unstable vitamin E (tocopherol), which is converted into vitamin E by dephosphorylation enzymes in the skin. Vitamin E is a useful fat-soluble vitamin that works in conjunction with water-soluble antioxidant compounds such as vitamin C to protect the skin from oxidative stress caused by ultraviolet rays and other factors. The type of tocopheryl phosphate salt used in the present invention is not particularly limited, but metal salts such as sodium salt, disodium salt, potassium salt, and dipotassium salt are preferred, and sodium tocopheryl phosphate is more preferred. Commercially available tocopheryl phosphates can also be used, for example, "Vitamin E Sodium Phosphate" manufactured by Showa Denko K.K.

[0010] (B) Component: alanylglutamine and / or hydroxyproline The aqueous cosmetic preparation of the present invention contains, as component (B), either alanylglutamine or hydroxyproline, or both. Alanylglutamine is a dipeptide formed by a peptide bond between the carboxyl group of alanine and the amino group of glutamine. Hydroxyproline is a secondary cyclic amino acid (monopeptide), also known as imino acid. These are commercially available products, for example, from Kyowa Hakko Bio Co., Ltd.

[0011] (C) Ingredient: Sclerotium gum Sclerotium gum is a polysaccharide gum produced by the fungus Sclerotium rolfsii using glucose as a substrate, and has a three-dimensional cross-linked triple helix structure.

[Example]

[0019] Each component was mixed with stirring to obtain an aqueous cosmetic preparation according to the composition shown in Tables 1 and 2 (the numerical values ​​for the blending represent mass %). The aqueous cosmetic compositions obtained were evaluated by the following methods, and the results are shown in Tables 1 and 2.

[0020] <Evaluation method> The aqueous cosmetics obtained by the above method were subjected to a sensory evaluation by three expert panelists, who jointly evaluated the sensation immediately after applying approximately 0.15 g of each aqueous cosmetic to the inside of the forearm, using the following scoring system, and gave the following scores. The sensation of firmness alone was also evaluated in the same way, immediately and six hours later. ·Penetration feeling The feeling of penetration is the sensation of the cosmetic being absorbed into the skin when applied, and is the opposite of the feeling of the cosmetic being repelled, with no sense of residual liquid felt after a certain time has passed since application. 〇: I feel it penetrates deeply. △: Feels like it penetrates slightly. ×: No penetration is felt. ·No creaking Squeakiness refers to a physical discomfort felt at the application site, such as excessive friction felt after applying a cosmetic to the skin, and can also be felt when the surface of the application site is covered with a film or has many irregularities, losing smoothness and causing a rough texture. 〇: No creaking. △: Almost no creaking is felt. ×: Creaking sensation. - Non-sticky Stickiness refers to the sticky or tacky feeling that remains even after a certain period of time has passed after applying a cosmetic to the skin. 〇: Does not feel sticky. △: Almost no stickiness. ×: Feels sticky. ·Firmness The firmness is the feeling that the skin feels taut when touched after applying a cosmetic product to the skin, and that the skin feels elastic when pressed with the fingers. 〇: I feel a very firm feeling. △: Feels slightly firm. ×: No firmness felt.

[0021] [Table 1]

[0022] [Table 2]

[0023] The aqueous cosmetics obtained in Examples 1 to 21 of the present invention, despite containing (A) tocopheryl phosphate, had excellent penetration and were free of any squeaky or sticky feeling, providing an excellent feel when used. Furthermore, the aqueous cosmetics obtained in Examples 1 to 21 of the present invention provided an unexpected effect of providing a firm feeling immediately after application, and maintaining that firm feeling even six hours later. In fact, when the aqueous cosmetics obtained in Examples 1 to 21 were applied to the entire face after an evening bath, the firm feeling remained the same the next morning as before going to bed, and the firm feeling could be felt throughout the day. In contrast, the aqueous cosmetics obtained in Comparative Examples 1 to 7, which did not contain any of the components (A) to (C) of the present invention, were inferior in penetration sensation, and also had a strong sense of at least one of squeaking and stickiness due to the tocopheryl phosphate (A), resulting in an inferior feel when used.
