The invention relates to a composition, in particular to a bioactive slow-release composition. The raw materials of the bioactive slow-release composition comprise 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 slow-release composition provided by the invention, high-concentration astaxanthin is coated in micelles formed by dipalmitoyl phosphatidylcholine, cholesterol, aliphatic primary amine and the like, so that the stability of astaxanthin can be improved, and the effects of sun screening, acne removing, whitening, wrinkle resisting and aging resisting can be effectively achieved for a long time; the astaxanthin is slowly released by the biological slow-release composition provided by the invention, so that the problems that the high-concentration astaxanthin directly contacts the skin to cause irritation to the skin and the like are prevented; in addition, a certain amount of taurate surfactant is added to promote the slow release effect and further improve the efficacy of the astaxanthin, so that the astaxanthin can be applied to various skin care products as an efficient active ingredient. |
