Fibroin composite coating liquid and method of preparing the same and applications

Abstract

The invention discloses a composite coating liquid of fibroin and a preparation method and an application thereof. The composite coating liquid of fibroin is composed of the following components: 2 to 10 wt percent of crosslinking agent, 0.5 to 2 wt percent of acetate acid, 10 to 20 percent of fibroin and water which accounts for the rest weight proportion. The preparation method of the invention comprises the steps of (1) the preparation of the fibroin and (2) the preparation of the composite coating liquid of fibroin. The fibroin of the invention has the functions of naturally moisturizing the skin, antisepsis, antianaphylaxis, etc. and is applicable to the preparation of lotions for women, infants or children; thus achieving the purposes of moistening the skin, absorbing moisture, resisting bacteria and treating and preventing skin allergy; the product prepared by the invention has significant functions of moistening the skin, absorbing moisture, venting, preventing skin allergy and inhibiting bacteria, especially has remarkable inhibited effect on pathogenic anaerobion and acid-producing bacteria.

Description

technical field

[0001] The invention relates to a silk protein composite coating solution, a preparation method and application thereof. Background technique

[0002] Silk protein contains 18 kinds of amino acids, of which glycine, alanine, and serine account for more than 70%. It is a nutritional substance with outstanding functions and is widely used in medicine, food, cosmetics, leather and fabrics. Daily hygiene and skin-friendly products (sanitary napkins, panty liners, diapers, cotton pads, etc.) have huge market potential. Silk protein is rich in serine and threonine, which are natural nutrients that are compatible with human skin; moreover, silk protein contains extremely rich polar side amino acids, rich in NMF, and has high-quality water absorption and radiation. Moisture and moisturizing properties can regulate the nutritional function of the skin; at the same time, studies have found that silk protein has a preventive effect on itching and eczema caused by weath...
