Abstract

The present invention provides a composition with long-lasting moisturizing effect and a preparation method and application thereof. The moisturizing composition includes the following components: glycerin, wrinkled carrageenan, sodium polyglutamate, sodium hyaluronate, L -Serine, sodium pyrrolidone carboxylate, betaine and pH adjuster. Based on the total weight of the moisturizing composition, the glycerin is 0.001-40 wt %, and / or the wrinkled carrageenan is 0.01-5 wt %, and / or the sodium polyglutamate is 0.01-5 wt %, and / or the sodium hyaluronate is 0.01-5wt%, and / or the L-serine is 0.01-2wt%, and / or the sodium pyrrolidone carboxylate is 0.001-15wt%, and / or the betaine is 0.001-15wt%, and / or the pH adjusting agent is 0.001-5wt%. Experiments have confirmed that the moisturizing composition of the present invention has a long-lasting moisturizing effect, and has good stability and skin feel, and has wide application prospects in the field of skin care products.

Description

technical field [0001] The invention relates to the field of skin care, in particular to a composition with moisturizing effect and a preparation method and application thereof. Background technique [0002] The skin has hygroscopic properties and moisturizing ability because the skin surface contains natural moisturizing factors, but due to various factors such as the environment, the lipid barrier of the skin surface is damaged, and the natural moisturizing factors are easily lost, resulting in dryness and desquamation of the skin. [0003] In response to this problem, many moisturizing skin care products achieve instant moisturizing effect by adding moisturizing agents, but as time goes on, most of the directly applied moisturizing agents are lost and not fully utilized, resulting in the product's moisturizing effect being significantly reduced soon. Most moisturizing products cannot achieve long-lasting moisturizing, and must be frequently used to achieve a certain moist...
