EPS composite acid for improving skin microbial barrier and preparation method of EPS composite acid

Abstract

The invention provides EPS composite acid for improving skin microbial barrier and a preparation method thereof, and the EPS composite acid is prepared from the following raw materials in parts by weight: 12-25 parts of lactobacillus extracellular polysaccharide extract, 10-20 parts of salicylic acid, 8-12 parts of capryloyl salicylic acid, 2-8 parts of citric acid, 3-6 parts of lactic acid, 2-7 parts of mandelic acid, 5-10 parts of glycolic acid, 3-8 parts of aldose disaccharic acid, 2-5 parts of composite amino acid, 10-40 parts of dispersion liquid and 8-25 parts of emulsifier. Through mixing, scientific proportioning and synergistic effect of the compound acids, the skin barrier function can be recovered, the percutaneous moisture loss can be improved, the proportion of the compound amino acids can be adjusted, the skin can be protected, and the damage to the skin barrier can be reduced.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to an EPS composite acid for improving skin microbial barrier and a preparation method thereof. Background technique [0002] The skin barrier is mainly composed of stratum corneum, structural lipids and skin lipid film, which protects various tissues and organs in the body from harmful external invasion and maintains the stability of the body's internal environment. Also included is the skin microbial barrier, which consists of the normal flora that colonizes the skin and mucosal surfaces. They can act as a barrier by competing with pathogens for binding epithelial cells and nutrients, or by secreting certain killing and bacteriostatic substances. The abnormal structure and function of the skin barrier are related to the etiology and pathological process of various skin diseases. Maintaining and repairing the skin barrier is of great significance to prevent bacterial invasion, r...

AI Technical Summary

Problems solved by technology

[0003] At present, mono-acid is used to repair the skin barrier, especially for the repair of the skin microbial barrier, and the single-acid peel has only the chemical and physical properties of one acid, and there are various defects and deficiencies, such as the peeling depth is not easy to control, After treatment, the skin is dry and irritated

Fruit acid skin peeling has uneven penetration, easy to over-penetrate, and must be neutralized by lye; salicylic acid skin peeling has limited penetration depth due to lipophilicity, and has limited curative effect on severe photoaging skin. prone to salicylic acid poisoning
