Embodiment 1

[0018] Use hyaluronic acid as the main raw material of the capsule wall, lycopene as the main raw material of the capsule core, weigh 100g of hyaluronic acid and 100g of lycopene, add 20g of emulsifier, which can be ethylene-maleic anhydride copolymer, and use the interfacial polymerization method , so that the capsule wall is wrapped on the surface of the capsule core to form lycopene hydrogel microcapsules with a diameter of 3 mm; the embedding rate of the microcapsules is 96.23%, and the lycopene content in the microcapsules is 95.23 %. The lycopene hydrogel microcapsules effectively isolate the active ingredients from external oxygen, dust, etc., and achieve effective protection.

[0019] Adding the lycopene hydrogel microcapsules to the anti-aging eye cream, the antioxidant activity of lycopene is 100 times that of vitamin E, so that the anti-aging eye cream added with the lycopene hydrogel microcapsules has strong Antioxidant function, thereby inhibiting skin aging and ...

Embodiment 2

[0022] Take guar gum as the main raw material of the capsule wall and arbutin as the main raw material of the capsule core, weigh 50g of guar gum and 25g of arbutin, add 15g of emulsifier, which can be ethylene-maleic anhydride copolymer, use interface Polymerization method, so that the capsule wall is wrapped on the surface of the capsule core to form arbutin hydrogel microcapsules with a diameter of 1 mm; the embedding rate of the microcapsules is 95.34%, and the arbutin content in the microcapsules is 95.62%, the microcapsules effectively achieve the purpose of isolating the active ingredients from the external oxygen, dust, etc., and achieve the protection effect.

[0023] Add the arbutin hydrogel microcapsules to the anti-aging essence, because arbutin can inhibit the activity of tyrosinase in the body and prevent the generation of melanin, so that the anti-aging essence added with arbutin hydrogel microcapsules The aging essence can remove spots and freckles, whiten the ...

Embodiment 3

[0026] With chitosan as the main raw material of the capsule wall and resveratrol as the main raw material of the capsule core, weigh 60g of chitosan and 20g of resveratrol, add 10g of emulsifier, which can be ethylene-maleic anhydride copolymer, use interface Polymerization method, the capsule wall was wrapped on the surface of the capsule core to form resveratrol hydrogel microcapsules with a diameter of 6 mm; the embedding rate of the microcapsules was 96.16%, and the resveratrol in the microcapsules The alcohol content is 94.28%. It can be seen that the resveratrol hydrogel microcapsules avoid the adverse effects of external oxygen, light, etc. on the active substances, and play a good protective role.

[0027] Add the resveratrol hydrogel microcapsules to the anti-aging mask, because resveratrol can inhibit lipid peroxidation, and can regulate the activity of antioxidant enzymes, and then has anti-oxidation effect, so that the addition of resveratrol The anti-aging mask ...

Abstract

The invention discloses a hydrogel microcapsule and application thereof in an anti-ageing cosmetic. The hydrogel microcapsule disclosed by the invention is a translucent spherical soft capsule in a core-shell structure, wherein a capsule wall is a hydrogel shell membrane, and a capsule core is an active substance mixture with an anti-ageing effect; the hydrogel microcapsule is formed from the capsule core and the capsule wall through an interface transmission reaction; the embedding rate of the hydrogel microcapsule is as high as 95% and steady under the illumination. The hydrogel microcapsule disclosed by the invention can be used as an additive for the anti-ageing cosmetic, and the microcapsule has the care effects of extreme moistening, crease resistance, freckle removing, whitening and the like on skin, so that the skin ageing is effectively delayed.

Description

technical field [0001] The invention relates to a hydrogel microcapsule and its application, in particular to a hydrogel microcapsule and its application in anti-aging cosmetics. [0002] Background technique [0003] 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 decline. For most beauty lovers, having flawless skin is a lifetime pursuit. After reali...
