Abstract

The invention discloses a skin protective agent and a preparation method thereof, relates to the technical field of skin protective agents, and aims at solving the problems that an existing skin protective agent is single in function, so that the skin repair time is short, and a wound surface cannot be effectively protected. The skin protective agent is prepared from the following raw materials in parts by weight: 10-40 parts of thermoplastic elastomer, 10-40 parts of sodium carboxymethyl cellulose, 1-10 parts of wool fat, 1-10 parts of sodium hyaluronate, 10-20 parts of liquid paraffin, 40-95 parts of adhesive and 15-70 parts of asiaticoside. The skin protective agent comprises an outer base material layer, a matrix layer and a protective layer, the matrix layer is located between the outer base material layer and the protective layer, and the matrix layer is of a bionic structure with pore diameters distributed in a gradient mode.

Description

technical field [0001] The invention relates to the technical field of skin protection agents, in particular to a skin protection agent and a preparation method thereof. Background technique [0002] Skin is an important tissue and organ that covers and protects the body surface. Skin defects and abnormalities caused by inflammation, ulcers, burns, congenital deformities and other reasons are common clinical phenomena. For this kind of tissue defect, the method of autologous skin transplantation is mostly used at present, but the source of autologous skin is extremely limited and it will cause secondary damage to the patient when the material is taken, which will affect the treatment process. In view of this, tissue engineered skin is the most potential treatment method, and acellular dermal matrix, as a natural extracellular matrix material, has good mechanical properties, histocompatibility and low immunogenicity, and is suitable for tissue It is a good matrix for repair ...
