Skin wounded area protecting composition and preparation method therefor

Abstract

The invention provides a skin wounded area protecting composition and a preparation method therefor. The skin wounded area protecting composition comprises the following ingredients in parts by weight: 4-15 parts of film former, 60-90 parts of solvent, 0.5-10 parts of plasticizer and 0.2-8.0 parts of humectant, wherein the film former is selected from one or more of ethyl cellulose, hydroxyethyl cellulose, nitrocellulose, polyvinyl acetate, polyvinyl formal, polyvinyl formal acetal, polyvinyl alcohol carboxyl butyraldehyde and an acrylic copolymer. The wounded area protecting composition has excellent properties, is short in film forming time, low in irritation, uniform and elastic in film, high in degree of comfort, good in waterproofing performance and good in air permeability and can beapplied to protection and nursing of various shallow wounded areas such as scratch, incised wounds and mild burn and scald; and the preparation method is simple and easy in operation and relatively low in cost, facilitates industrialization and has a good application prospect.

Description

technical field

[0001] The invention belongs to the field of medical technology, and in particular relates to a skin wound protection composition and a preparation method thereof. Background technique

[0002] In daily life, human skin will be damaged by various external factors, such as abrasions, scratches, abrasions, burns, scalds, etc. Improper treatment of local injuries may cause varying degrees of inflammatory reactions, resulting in local redness and swelling, and even tissue necrosis or systemic invasive infection in severe cases, which is life-threatening.
