Problems solved by technology

Hyaluronic acid has very strong water absorption capacity, good osmotic pressure and viscoelasticity of aqueous solution, affinity adsorption, water molecules are fixed in the network formed by hyaluronic acid molecules through hydrogen bonds, and are not easy to be lost, but its stability is poor. Sensitive to strong alkali, heat, free radicals and hyaluronidase, prone to degradation

Abstract

The invention discloses skin lotion having effect of resisting oxidation. The skin lotion comprises the raw materials in percentage by weight of 5-9% of sweet almond oil, 7-14% of octadecanol, 4-7% ofsimethicone, 2-6% of caprylic triglyceride, 1-4% of a lycopene antioxidant, 3-5% of hydrolyzed protein, 10-15% of glycerine, 0.1-0.5% of ethylenediaminetetraacetic acid disodium salt and the balancedeionized water. The formula is scientific in components and compounding ratio, the prepared skin lotion is uniform in texture, good in using skin feeling, mild, and non-irritating; and the high-hydrophilicity lycopene antioxidant is added and is obtained by esterifying hyaluronic acid and lycopene intermediate acid, and the problems that the lycopene intermediate is poor in water solubility and difficult to absorb, are solved. The lycopene intermediate has high antioxidation, so that the problem that hyaluronic acid is degraded when being in contact with free radicals can be solved, the antioxidant can eliminate surplus free radicals when entering skin and can quench single oxygen, the skin can durably maintain plump and flexible, and wrinkles are avoided.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a skin care emulsion with antioxidant effect. Background technique [0002] Living cells are constantly producing free radicals in the course of their normal function. Free radicals are highly reactive species capable of irreversibly reacting with many biomolecules, causing progressive degradation of biological systems. Free radicals are usually neutralized by antioxidant enzymes produced by the body and antioxidants derived from nutrients. Oxidative stress induced by free radicals is a major factor in the long-term tissue degeneration associated with aging. [0003] Oxygen free radicals in the human body mainly refer to: hydroxyl free radicals (OH ), singlet oxygen, superoxide anion free radicals (O 2 -) and hydrogen peroxide (H 2 o 2 ). [0004] Lycopene is a polyunsaturated aliphatic hydrocarbon with outstanding antioxidant capacity, which can convert the a...
