Description

[Technical Field]

[0001] The present invention relates to a cosmetic composition that has excellent penetration and moisturizing properties, is non-sticky, and provides an excellent feel when used. [Background technology]

[0002] The skin has the important function of preventing moisture loss from the body and protecting the body from external stimuli. To maintain the skin's natural functions, it is important to replenish moisture in the skin with cosmetics and other products, prevent evaporation, and maintain a normal condition.

[0003] Various moisturizing agents with high moisture-retaining capacity have been investigated and formulations of these agents have been proposed for moisturizing cosmetics to prevent dryness of the skin and hair.

[0004] Patent Document 1 proposes a cosmetic composition containing a phospholipid derivative, hydrolyzed hyaluronic acid, bilberry extract, a nonionic surfactant, and a specific copolymer as a highly moisturizing cosmetic, while Patent Document 2 proposes a cosmetic composition containing peach fruit extract.

[0056] (Manufacturing method) Example 1, Comparative Example 2, Comparative Example 3 A: Mix ingredients 1 to 7 evenly. B: Mix ingredients 8 to 11 evenly. C: Add B to A and emulsify. Example 2, Comparative Example 1 A: Mix ingredients 1 to 11 evenly.

[0057] As is clear from Table 1, Examples 1 and 2, which contained brown algae extract and the amphiphilic substances bisethoxydiglycol cyclohexane-1,4-dicarboxylate or polyglyceryl-4 / polyglyceryl-6 laurate, were good in terms of penetration feel, moisturizing effect, stickiness, and stability over time. On the other hand, Comparative Example 1, which lacked both the brown algae extract and the amphiphilic substance, was poor in terms of penetration feel, moisturizing effect, and stickiness, and Comparative Examples 2 and 3, which lacked either the brown algae extract or the amphiphilic substance, were poor in terms of penetration feel, stickiness, and stability over time, although they exhibited a moisturizing effect.

[0058] From this, it was found that by containing a brown algae extract and an amphiphilic substance, the cosmetic composition of the present invention can obtain a cosmetic composition that has excellent moisturizing effect and feel when used, is non-sticky, and has excellent stability over time.

[0059] The cosmetic compositions of Examples 3 to 9 shown below all had excellent stability over time, and the sensory evaluations of the penetration feeling upon application, the lack of stickiness after application, and the moisturizing feeling on the skin all had average scores of 3.5 or higher by all panels, suggesting that they have excellent sensory properties.
