Skin care composition

Abstract

The invention provides a skin care composition. The skin care composition comprises hydroxyethyl cellulose, sodium alginate, a humectant and water, wherein the humectant is selected from one or more of glycerol, butanediol and propylene glycol. The humectant in the composition is an acknowledged safe material, and the sodium alginate and the hydroxyethyl cellulose are both prepared by modifying and refining biomass raw materials, so that the safety is higher. The composition has the advantages of fewer components, simpler production operations and lower production cost. Through a damp-heat sterilization test, the composition is higher in cell proliferation rate, lower in cytotoxic reaction level and more reliable.

Description

technical field [0001] The invention relates to the field of skin care products, in particular to a skin care composition and its application. Background technique [0002] Skin aging is a phenomenon of skin aging caused by natural or unnatural factors. After birth, the skin tissue becomes more and more developed, and its function is gradually active. When it reaches a certain age, it will begin to degenerate. This degeneration often proceeds slowly without people's awareness. It is a continuous and gradual physiological process that directly affects the skin. appearance and function. [0003] The phenomenon of skin aging is mainly manifested in two aspects: one is the low physiological function. The function of sebaceous glands and sweat glands declines, the excretion of sweat and sebum decreases, the skin gradually loses its luster and becomes dry, and the blood circulation function decreases to supplement the necessary nutrients for the skin, so the skin wounds of the e...

The hyaluronic acid medical sterile dressing comprises the following components: 0.01%-1% (w / v) large molecular weight hyaluronic acid or its salt, 0.01-1% (w / v) low molecular weight hyaluronic acid or its salt Salt, 0.01%-1% (w / v) oligomeric hyaluronic acid or its salt, 0.01%-1% (w / v) nano silver, 0.05-2% (w / v) carbomer, 0.5-5 % (w / v) glycerin, 0.5-5% (w / v) propylene glycol, 0.05-3% (w / v) triethanolamine and the rest of water; the hyaluronic acid medical sterile dressing of this patent, due to the large The combination of molecular weight, small molecular weight and oligomeric hyaluronic acid makes hyaluronic acid with different molecular weights play a better synergistic effect, and combined with nano-silver, when hyaluronic acid medical sterile dressing acts on the damaged skin, It can achieve the multi-effect combination of moisturizing and antibacterial; however, the patent uses irradiation to sterilize, and the radiolysis products of the product after irradiation are unknown, and the ingredients are obviously aged; and the patent adds complex ingredients from chemical synthesis, Especially carbomer, such components will decompose into unknown products after irradiation sterilization, which makes the product a great safety hazard; and moist heat sterilization is relatively safe; secondly, the patented components are complex, resulting in Complicated production operations and increased production costs
