Problems solved by technology

Aiming at the current liquid bandage products on the market, there are still several core problems. 1. The product forms a film quickly, but a large amount of volatile organic reagents are added, which is more irritating and tingling when used; 2. The film-forming performance of the product is good, and the irritation is low, but most of them are water-soluble substances. Poor, or the formed film has insufficient toughness, is easy to break, or has poor adhesion, is easy to lift off, and cannot perform the normal film protection function

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. [0003] At present, care for superficial wounds or small wounds on the body surface such as abrasions, scratches, abrasions, burns, and scalds mainly includes traditional adhesive bandages and new liquid bandages. The characteristics of traditional adhesive bandages are self-evident, and liquid bandages are a new type of high-end functional medical wet dressings, mainly using biocompatible polyurethane PU film,...
