Abstract

The invention provides a multifunctional compound moisturizing stock solution and application thereof. The composite moisturizing stock solution contains polyglutamic acid or its salts in three molecular weight ranges, and also contains polyglutamic acid hydrogel or polyglutamic acid hydrogel with strong water absorption and good film-forming properties. The compound moisturizing stock solution has superior moisturizing effects both in vitro and on human skin, and its ingredients are highly safe, and cells, animals, and human bodies do not show toxicity and irritation. The compound moisturizing stock solution can also be applied in various cosmetics, and can be prepared into lotion, cream, facial mask and the like.

Description

technical field [0001] The invention belongs to the field of cosmetics, and relates to a polyglutamic acid-containing multifunctional composite moisturizing stock solution, a preparation method and application thereof. Background technique [0002] Healthy and smooth skin comes from effective moisturizing. The humectant material used in skin care products should not only have water absorption capacity, but also water retention capacity to prevent water evaporation, and must be safe. Traditional humectants for the cosmetic industry include glycerin, sorbitol, sodium lactate, propylene glycol, and amino acids, among others. The water absorption capacity, safety and stability of these humectants limit their practical application effects. Although glycerin, sorbitol and propylene glycol have good water retention properties, they tend to increase the viscosity of skin care products and reduce the skin feel; Good water retention capacity, but difficult to emulsify in product form...
