Problems solved by technology

[0003] Existing anti-aging substances are generally unstable in nature and are easily affected by environmental factors such as light and temperature. If these anti-aging substances are directly added to cosmetics without protection, they are easily decomposed by light; and the unique pH value of cosmetics , will also have a certain negative impact on these anti-aging substances

Abstract

The invention discloses an antioxidant essence microcapsule and a preparation method thereof. The microcapsule is a transparent spherical soft capsule of a core-shell structure, wherein the capsule wall is a sericin shell membrane, a capsule core is antioxidant essence, the mass ratio of the capsule wall to the capsule core is (1-2):1, and the diameter of the microcapsule is 1-5 mm. The antioxidant essence comprises, by weight, 12-25 parts of astaxanthin, 11-21 parts of tocopherol, 8-16 parts of tocopherol succinate, 3-11 parts of ascorbyl stearate, 1-8 parts of ascorbyl palmitate, 2-8 parts of jojoba oil, 2-8 parts of retinol, 1-7 parts of propylene glycol propionate, 1-6 parts of glycerol and 2-6 parts of sorbitol. The antioxidant essence microcapsule is slightly influenced by environmental factors such as light and heat, and is not easy to decompose and stable in property; antioxidant essence microcapsule particles are in a regular spherical shape, the capsule wall is uniform in thickness, the microcapsule has stable strength and elasticity, and the embedding effect of the capsule core is ensured.

Description

technical field [0001] The invention belongs to the technical field of cosmetics and relates to an antioxidant essence, in particular to an antioxidant essence microcapsule and a preparation method thereof. Background technique [0002] Human aging or aging is an inevitable law in the growth process of biological life, and is a ubiquitous physiological process. The internationally recognized theory of aging is the free radical theory. Through a large number of in vivo and in vitro experiments, it can be proved that the key cause of the degenerative changes in the aging process is the free radicals produced during the normal metabolism of cells. Free radicals are intermediate products of normal metabolism. They have a strong reaction ability and can oxidize various substances in cells, damage biofilms, and then cause the structure and function of the skin to decline, and the adaptability and resistance to decrease. For most beauty lovers, having flawless skin is a lifetime p...
