Abstract

The invention provides multi-efficiency compound moisturizing essence and application thereof. The compound moisturizing essence consists of polyglutamic acid or salt thereof within three molecular weight ranges, and further consists of a polyglutamic acid hydrogel or a polyglutamate hydrogel which is quite strong in water-absorbing capacity and is good in film-forming property. The compound moisturizing essence, in vitro and for human skin, has an excellent moisturizing effect, and the compound moisturizing essence is high in safety of ingredients thereof and free from toxicity and irritation to cells, animals and human bodies. The compound moisturizing essence can be also applied to various cosmetics; and the compound moisturizing essence can be prepared into emulsions, creams, facial masks 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...
