Abstract
Description
Technical Field
[0001] The present invention relates to an aqueous composition.
Background Art
[0002] Aqueous cosmetics such as lotions are widely used to penetrate the skin and impart a moisturizing feeling. It is common to blend lipophilic components in aqueous cosmetics, and usually the lipophilic components are solubilized in an aqueous medium. Such aqueous cosmetics are more preferably transparent because they can administer lipophilic components and hydrophilic components simultaneously and have excellent aesthetics (Patent Document 1, etc.).

[0074] The present invention provides an aqueous composition in which oily components are transparently solubilized and incorporated. Furthermore, in certain embodiments, the composition becomes more compatible with sebum and penetrates deep into the pores, resulting in a more easily absorbed feel. Such a composition is suitable for topical skin preparations such as cosmetics, and is highly industrially useful as it meets the needs of consumers seeking excellent functionality and a pleasant appearance.
