Description

Moisturizing composition and preparation method thereof

Technical Field

The invention relates to the field of skin care products, and particularly relates to a moisturizing composition and a preparation method thereof.

Background

With the pace of modern life increasing, more and more young people work and rest irregularly, and the skin becomes sensitive and fragile. Dry skin and lack of water become one of the external causes of sensitive and fragile skin, and therefore, a large number of moisturizing products are available on the market.

The skin is the largest organ of the human body, not only plays a role in protecting the skin, but also plays a role in keeping one's health and beauty, particularly the facial skin, not only influences the appearance of the skin when the skin is lack of water and dry, but also causes uncomfortable feelings to consumers subjectively and possibly causes deterioration of certain skin diseases, and leads to premature aging of the skin. The hydration state and the loss degree of the skin are directly related to the softness and elasticity of the skin, and the moisture degree of the skin can be maintained to enhance the elasticity of the skin, ensure the normal metabolism of the skin and reduce the generation of wrinkles and color spots. The moisturizing effect is the most basic function of the skin care cosmetic, and how to improve the moisturizing effect of the skin care cosmetic has important significance on research and development and medical clinical application of the skin care cosmetic.

Most of the existing moisturizing products are pure water formulations, the formulation has the defects that long-term moisturizing effect is lacked, a large amount of alcohol is used as a solvent to dissolve raw materials with poor water solubility, the moisturizing effect of the product is achieved, but the moisturizing agent is not suitable for sensitive skin, the moisturizing effect cannot be better achieved, the skin is more sensitive after long-term use, and the absorption effect is poor.
