Abstract

The invention provides a hydrogel cosmetic composition and a preparation method thereof, and belongs to the field of cosmetics. The hydrogel cosmetic composition specifically comprises a hydrogel component and a hyaluronic acid solution with a mass ratio of (5-42):1, wherein each 100 parts of the hydrogel component includes the raw materials in parts by mass: 1-3 parts of chitosan, 1-10 parts of humectants, 0.1-1 part of transdermal absorption enhancer, 1-15 parts of Chinese herbal medicine extract, 0.4-1 part of vegetable oil, 0.001-0.01 part of plant essential oil, and deionized water with an amount enabling the total amount to be 100 parts. The hydrogel cosmetic composition of the invention has the effects of whitening skin, lightening spots, treating acnes and repairing scars, and is non-irritating to skin by using natural substances.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to a hydrogel cosmetic composition and a preparation method thereof. Background technique [0002] Hydrogel is a new type of polymer material, which contains a special three-dimensional network structure and has good biocompatibility, biodegradability and water retention. Hydrogels are widely used in industry, agriculture, medical treatment, daily chemical and other fields. But the effect of existing gel cosmetics is not remarkable. For example, the patent CN 101843567A relates to a gel sheet for cosmetic film application. The method uses synthetic polymers as raw materials and adds a cross-linking agent to prepare a gel sheet that has a moisturizing effect and prevents liquid from dripping from the gel. of hydrogel. The gel sheet for cosmetic sticking films solves the problem of dripping onto clothing during use while improving the moisturizing properties of the exuding solu...
