Abstract
The present invention relates to a moisturizing, hydrating and whitening emulsion and a preparation method thereof. Glabridin, L-ascorbic acid-glucoside and vitamin E are added, the multiple components have synergistic effects, glabridin usage is reduced, tyrosinase activity inhibition rate is increased and reaches 97.27%, SOD, L-ascorbic acid-glucoside and vitamin E achieve the synergistic effects, free radicals are removed, melanin formation is reduced, nicotinamide is added to inhibit melanin particles from being transmitted to keratinocytes and increase skin renewal speed, the skin is whitened in multiple ways, and the effects are remarkable; and palmitoyl pentapeptide-3 is added to stimulate collagen, elastic fiber and hyaluronic acid proliferation, so that water content and water locking degree of the skin are improved, the skin thickness is increased, and fine wrinkles are reduced. Coconut oil, small molecular hyaluronic acid, ceramide, butanediol and glycerin are added for moisturizing and hydrating. The product does not contain essence or preservatives, contains few components, is safe and does not easily cause allergy.
Description
technical field [0001] The invention belongs to the technical field of cosmetics, in particular to a moisturizing, moisturizing and whitening emulsion and a preparation method thereof. Background technique [0002] Healthy and fair skin is a hot spot for most Asian women. Chinese women have always advocated the whitening effect of "skin like snow, gel like fat". In recent years, with the improvement of people's quality of life, the demand for whitening cosmetics has also increased. There are many methods of whitening, such as: [0003] (1) prevent melanin synthesis [0004] Tyrosinase, dopachrome interconverting enzyme, and 5,6-dihydroxyindole-2-carboxylate oxidase are the most important biological enzymes in the process of melanin formation, and tyrosinase is the rate-limiting enzyme in this process , tyrosinase mainly catalyzes the hydroxylation of monohydric phenols to generate dihydroxy compounds and the oxidation of catechol to generate catechols. These two types of r...
