Retaining type continuous moisturizing cosmetic composition with network structure

Abstract

The invention discloses a resident type continuous moisturizing cosmetic composition with a network structure. The resident type continuous moisturizing cosmetic composition comprises at least one polyurethane-7; at least one humectant, the humectant comprising at least one pyrrolidone carboxylic acid, pyrrolidone carboxylate group; and at least one humectant, said humectant comprising at least one erythritol. The moisturizing agent has the beneficial effects that when the moisturizing agent is applied to the skin, a film can be formed, the moisturizing agent is distributed in the film and slowly permeates into the surface of the skin through the film, the staying time of the moisturizing agent on the skin is prolonged while the irritation of the moisturizing agent to the skin is reduced, the moisturizing time of the skin is prolonged, and the moisturizing agent can be widely popularized and applied.

Description

technical field [0001] The invention relates to a cosmetic composition and its application and use method, in particular to a network-structured resident type continuous moisturizing cosmetic composition. Background technique [0002] Water is the primary condition for maintaining the healthy shape of the skin. The amount of water in the skin determines whether the skin is tender, plump, shiny and soft. Under normal circumstances, the water stored in the skin accounts for about 18% to 20% of the total water in the adult human body.
