Double hyaluronic acid stock solution and preparation method thereof

Abstract

The invention relates to the technical field of cosmetics, and discloses a double hyaluronic acid stock solution and a preparation method thereof. The double hyaluronic acid stock solution is preparedfrom the following raw material components in percentage by weight: 0.05%-0.5% of hyaluronic acid A, 0.05%-5% of hyaluronic acid B, 0.01%-1% of transparent Xanthan gum, 3%-9% of glycerin, 2%-6% of butanediol, 0.5%-5% of oat kernel extract, 0.5%-5% of oat beta-glucan, 0.5%-5% of moisturizing factors, 1%-5% of aloe barbadensis leaf juice, 0.1%-0.5% of a polyacrylate cross-linked polymer-6, 0.005%-0.008% of essence, 0.02%-0.04% of a solubilizer, 0.4%-0.6% of a preservative and the balance of deionized water. According to the double hyaluronic acid stock solution and the preparation method thereof, the ratio of two kinds of different molecular weight hyaluronic acid are reasonably adjusted in a ground-breaking mode to form a thin film on the surface of skin, so that moisture in the skin is effectively locked, the effect of long-term moisturizing is achieved, and meanwhile, the skin is smooth but not greasy, no matter in a cold winter or a hot summer, the use experience is good, the cost is lower, and the double hyaluronic acid stock solution is easy to accept by the public.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a double hyaluronic acid stock solution and a preparation method thereof. Background technique [0002] Most of the water-based moisturizing products have defects in moisturizing durability because they do not contain oil. If you blindly increase the moisturizing agent to prolong the moisturizing effect, the cost is high and it is not easy to be accepted by the public; although emulsified moisturizing products contain oil, moisturizing The effect is strong, but it tends to give people a greasy feeling in hot seasons, and the use experience is not good. Therefore, hyaluronic acid has appeared on the market as a better moisturizing product. Hyaluronic acid, also known as hyaluronic acid, is an ideal natural moisturizing factor, which can promote the absorption of nutrients, improve skin nutrition metabolism, and make the skin soft and smooth. Hyaluronic acid can be divided into...

Hyaluronic acid can be divided into small molecular hyaluronic acid and macromolecular hyaluronic acid according to molecular weight. The moisturizing effect of small molecular hyaluronic acid is much higher than that of macromolecular hyaluronic acid, but it is expensive. When the amount added is too large, the production cost is too high. When the amount added is too low , the skin care effect is not obvious, therefore, how to improve the moisturizing effect of hyaluronic acid products under the premise of controlling reasonable costs is a difficult problem facing the cosmetics industry
