EPS (Expandable Polystyrene) and mussel extract compounded skin barrier repairing dressing and preparation method thereof

Abstract

The invention provides EPS (Expandable Polystyrene) and mussel extract compounded skin barrier repairing dressing and a preparation method thereof. The EPS and mussel extract compounded skin barrier repairing dressing comprises the following raw materials in percentage by weight: 0.05%-0.12% of hyaluronic acid, 0.5%-0.8% of sodium alginate, 0.06%-0.15% of tremella heteropolysaccharide, 6%-8% of glycerol, 0.3%-1% of dihydric alcohol, 1%-2% of trehalose, 1%-2% of mannose, 0.02%-0.05% of lactic acid bacteria exopolysaccharide, 0.03%-0.08% of a mussel extract, 1%-2% of betaine, 1.5%-2.3% of amino acid, 1.8%-2.5% of PCA (pyrrolidone carboxylate) sodium, 0.01%-0.03% of a preservative, and the balance of water. According to the preparation method of the EPS and mussel extract compounded skin barrier repairing dressing, the lactic acid bacteria exopolysaccharide and the mussel extract are compounded, the tremella heteropolysaccharide, the trehalose, the mannose and the dihydric alcohol are combined, the betaine, the PCA sodium and the like are matched, and optimized proportion is adopted, so that the prepared dressing has good anti-inflammatory activity and high skin wound healing rate; and thus, the dressing can better and quickly repair damaged skin, has higher skin barrier repairing capacity, and is ensured with good tolerance.

Description

technical field [0001] The invention relates to the technical field of skin barrier repair, in particular to a skin barrier repair dressing composed of EPS and mussel extract and a preparation method thereof. Background technique [0002] Repairing skin barrier dressings form a protective layer on the surface of skin wounds to act as a physical barrier, and are used for the care of superficial wounds and surrounding skin. Commercially available medical dressings have a certain adsorption effect on damaged skin, but they often suffer from poor tolerance, blocked absorption of nutrients, and slow skin barrier repair. [0003] Lactic acid bacteria exopolysaccharides (exopolysaccharides, EPS) is a polysaccharide compound secreted outside the cell during the growth and metabolism of lactic acid bacteria, which belongs to a kind of microbial polysaccharides. First, EPS can improve the rheology, texture, stability, water holding capacity and taste of food, etc.; the second is the ...
