Preparation for sunscreen humectant of shampoo

Abstract

The invention discloses preparation for a sunscreen humectant of a shampoo, and belongs to the field of chemical engineering. The light yellow transparent sunscreen humectant of the shampoo is prepared by the following steps of: putting raw materials, such as feather waste, sodium hydrogensulfite, urea and lauryl sodium sulfate into a container; adding distilled water, uniformly mixing the raw materials with the distilled water; respectively feeding nitrogen and argon to isolate air; reacting under the constant-temperature condition, leaching, and washing non-melted feathers by the distilled water; collecting a cleaning solution; and dialyzing the solution obtained by leaching and the cleaning solution in flowing water. The preparation method is simple in technique and convenient to operate; and the obtained product can be linked with hydrophilic groups exposed in damaged hairs to form a bond and achieve effects of repairing, moisturizing and enhancing. Compared with a chemical sunscreen, the sunscreen humectant does not have toxic and side effects; a human body is not allergic to the sunscreen humectant; and the sunscreen humectant is relatively high in hair adsorbability and is an ideal and natural sunscreen hair protection additive.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to the preparation of a sunscreen moisturizer used in shampoo. Background technique [0002] Feathers are derivatives of keratinized epidermal cells of birds and poultry, accounting for 10% of their body weight, of which the protein content is more than 80%. my country's annual output of feather waste reaches more than 700,000 tons, but most of them are simply processed into feather powder and then exported directly, and most of them are discarded and pollute the environment. [0003] The main component of feathers is β-keratin, and feather keratin molecules are very stable through disulfide bonds, hydrogen bonds and other cross-links. The keratin hydrolysis solution contains polypeptides and various amino acids, and its molecular structure has many hydrophilic groups (such as -NH 2 , -COOH), so that it has good moisturizing and hygroscopicity, adding it to skin care p...
