Abstract

The invention relates to a composition, and in particular, relates to a bioactive sustained-release composition. The bioactive sustained-release composition comprises the raw materials: astaxanthin, dipalmitoyl phosphatidylcholine, cholesterol, aliphatic primary amine, deionized water and ethanol. The aliphatic primary amine is alkyl primary amine of C12-C18. According to the bioactive sustained-release composition provided by the invention, the high-concentration astaxanthin is wrapped in micelles formed by dipalmitoyl phosphatidylcholine, cholesterol, aliphatic primary amine and the like, sothat the stability of the astaxanthin can be improved, and the effects of sun protection, acne removal, whitening, wrinkle resistance and aging resistance can be efficiently achieved for a long time;through the biological sustained-release composition provided by the invention, the astaxanthin is slowly released, and the problems that the high-concentration astaxanthin is in direct contact withthe skin to cause irritation to the skin and the like are prevented; in addition, by adding a certain amount of taurine salt surfactant, the slow release effect is promoted, the astaxanthin effect isfurther improved, and the astaxanthin composition can be applied to various skin care products and serves as an efficient active ingredient.

Description

technical field [0001] The present invention relates to a composition, more particularly, the present invention relates to a biologically active sustained-release composition. Background technique [0002] Astaxanthin is a terpene-like unsaturated compound, which can easily react with free radicals to scavenge free radicals and play an antioxidant role. It is the strongest antioxidant found in nature by humans so far. At the same time, astaxanthin has a strong ability to eliminate free radicals, which can prevent skin cells from being damaged by free radicals, reduce wrinkles and freckles, and is widely used as a new cosmetic raw material in creams, emulsions, lip balms, skin care products and other cosmetics. However, because astaxanthin contains unsaturated bonds, it may decompose and lose its activity, and when using high-concentration astaxanthin, if high-concentration astaxanthin directly contacts the skin, it may cause skin irritation or even allergies, and if you use...
