Problems solved by technology

Hyaluronic acid is widely used in the field of skin products (pharmaceuticals for external use, medical devices, cosmetics), but most of them only use hyaluronic acid with a molecular weight in a certain range, which only has some characteristics of hyaluronic acid, and does not exert its full effect. There will be significant differences in the performance and efficacy of products with the same name between different companies, or even between different batches of the same company

Abstract

The invention discloses a preparation method of a compound anti-scar emulsion biological dressing. The preparation method comprises the following steps: 1) preparing a liquid A from hyaluronic acid and water; 2) preparing a liquid B from a growth factor, glycerin and water; and 3) preparing a liquid C from composite active peptide, hydroxyethyl cellulose, glyceryl stearate, xanthan gum, tridecyl alcohol, phenoxyethanol, a witch hazel extract, a scutellaria baicalensis root extract, a raspberry extract, a radix sanguisorbae extract, an onion extract and water; 4) uniformly mixing the liquid A,the liquid B and the liquid C, and filling to obtain the compound anti-scar emulsion biological dressing. According to the compound anti-scar emulsion biological dressing prepared by the method, by compounding gradient hyaluronic acid and active components such as small active peptides, growth factors and plant extracts, skin repairing, protection and skin care of the active components of the active components can be fully performed, efficacy stability of the product is guaranteed, and wound healing and scar prevention and reduction can be promoted.

Description

technical field [0001] The invention relates to a preparation method of a compound anti-scar emulsion biological dressing. Background technique [0002] Human skin is an organ directly exposed to the external environment. It is often damaged and eroded by various external factors, resulting in trauma or defect of skin tissue, which requires ideal products for repair and care. The current dressing products mainly focus on protecting the wound environment, promoting wound healing, and preventing wound infection. Although they have played a good role in wound treatment, they do not involve the prevention and reduction of scar formation. The formation not only affects the appearance, but also causes symptoms such as poor perspiration and severe itching, causing great pain to the patient. [0003] With the development of molecular biology, the research on the application of biomaterials in medical dressings is increasing, and a lot of results have been obtained, such as collagen...
