Abstract

The invention provides a composition with a long-acting moisturizing effect as well as a preparation method and application thereof. The moisturizing composition is prepared from the following components: glycerol, chondrus crispus, sodium polyglutamate, sodium hyaluronate, L-serine, sodium pyrrolidone carboxylate, betaine and a pH regulator. Based on the total weight of the moisturizing composition, the glycerin accounts for 0.001-40 wt%, and / or the chondrus crispus accounts for 0.01-5 wt%, and / or the sodium polyglutamate accounts for 0.015 wt%, and / or the sodium hyaluronate accounts for 0.01-5 wt%, and / or the L-serine accounts for 0.01-2 wt%, and / or the sodium pyrrolidone carboxylate accounts for 0.001-15 wt%, and / or the betaine accounts for 0.001-15 wt%, and / or the pH regulator accountsfor 0.001-5 wt%. Experiments prove that the moisturizing composition disclosed by the invention has a long-acting moisturizing effect, has good stability and skin feeling, and has a wide applicationprospect 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 its preparation method and application. Background technique [0002] The skin has hygroscopicity and moisturizing ability because the skin surface contains natural moisturizing factors, but due to various factors such as the environment, the lipid barrier on 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 add moisturizers to achieve instant moisturizing effects, but as time goes by, most of the moisturizers that are directly applied are lost and not fully utilized, resulting in a significant reduction in the moisturizing effect of the product. Most moisturizing products cannot achieve long-term moisturizing, and moisturizing products must be used frequently to achieve a certain moisturi...
