Abstract

The present invention provides: a dispersion composition including a carotenoid-containing oily component, the dispersion composition being obtained by mixing an aqueous dispersion containing emulsionparticles containing the carotenoid-containing oily component and a phospholipid or a derivative thereof with an aqueous composition containing ascorbic acid or a derivative thereof and an oily component that is 20% by mass or less relative to the mass of the whole dispersion composition, and the dispersion composition having emulsion particles having an average particle diameter of 200 nm or less; a dispersion composition including a carotenoid-containing oily component, the dispersion composition being obtained by mixing an aqueous dispersion containing emulsion particles containing a carotenoid-containing oily component and a phospholipid or a derivative thereof with an aqueous composition containing ascorbic acid or a derivative thereof and a pH adjusting agent, and the dispersion composition having a pH value in the range of 5 to 7.5; and a cosmetic preparation for skin care including one or other of the dispersion compositions.

Description

technical field [0001] The present invention relates to a dispersion composition, a cosmetic for skin care, and a method for producing the dispersion composition, in particular to a dispersion composition in which an oily component containing carotenoids is dispersed in an aqueous composition, and a skin care product using it Process for the manufacture of cosmetics and dispersion compositions thereof. Background technique [0002] Carotenoids are naturally occurring yellow to red terpenoid pigments found in plants, algae and bacteria. One of the carotenoids, astaxanthin (including astaxanthin and its esters, etc.), is widely distributed in animals and plants in nature, and can be mainly used as a coloring agent for fish or chicken. In addition, astaxanthin has antioxidant effect, anti-inflammatory effect (for example, refer to Japanese Patent Application Publication No. 2-49091, Japanese Patent Application Publication No. 9-143063), anti-aging effect (for example, refer to...
