preparation example Construction

[0053] In a specific embodiment, the preparation method of the cosmetic composition containing hyaluronic acid and / or its derivatives is provided, which includes:

[0054] Accurately weigh the required amount of hyaluronic acid or its salt, polyglutamic acid or its salt in a beaker;

[0055] Add one or more of butanediol, propylene glycol, 1,3-propanediol, 1,2-pentanediol, polyethylene glycol, dipropylene glycol, and hydrogenated lecithin in the required amount, stir well, and add an appropriate amount at 80℃~ 90 ℃ deionized water, use a stirrer to stir at high speed until the dispersion is uniform;

[0056] Cool down to 45°C;

[0057] Add the required amount of tetrahydromethyl pyrimidine carboxylic acid, acetylglucosamine, ergothioneine agaricus extract, aminobutyric acid, and brown rice fermentation extract;

[0058] Stir well.

[0059] In a third aspect the present application relates to the use of a cosmetic composition as described above.

Abstract

The present invention relates to a cosmetic composition containing hyaluronic acid and / or a derivative thereof, the cosmetic composition further comprising polyglutamic acid and / or a salt thereof; the invention further relates to a preparation method of the cosmetic composition and application of the cosmetic composition in preparation of cosmetics.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a cosmetic composition containing hyaluronic acid and / or derivatives thereof, a preparation method and application thereof. Background technique [0002] The skin is the largest organ of the human body, which constitutes the first barrier for the human body to resist the influence of the external environment, and its aging is also the most direct manifestation of human aging. With the growth of age, human skin changes and declines in tissue form, function, and clinically, manifested as: skin thinning, dryness, roughness, relaxation, loss of elasticity, pigmentation spots, wrinkles, etc. In response to the above problems, skin care products with moisturizing, whitening, and anti-aging effects have been developed. However, due to problems such as unsatisfactory penetration of active ingredients and only staying on the skin surface, the skin care effects of skin care products have...
