Embodiment 3

[0050] Embodiment 3: The silk peptide-based surfactant in embodiment 1 and embodiment 2 can be prepared by the following reactions of fatty acid chloride and silk peptide compound of certain molecular weight:

[0051]

[0052]

[0053]n=8, 10, 12, 14, 16, 18, the molecular weight of silk peptide is 300~3000.

[0054] The specific preparation method is as follows: dissolve 5.6g silk fibroin peptide and 1.6g sodium hydroxide in a mixed solvent of 40mL distilled water and 60mL acetone, stir and dissolve in a 500mL four-necked flask. 0.04 mol of acid chloride was added dropwise at 10°C with a dropping funnel, and 0.5 mol / L of sodium hydroxide solution was added dropwise at the same time to maintain the pH of the system at 9. After the addition was complete, the temperature was raised to 25°C, and the reaction was continued for 3 hours with stirring. After stopping the reaction, use 0.6 mol / L hydrochloric acid to acidify to pH=1-2, then use Buchner funnel to suction filter, c...

Abstract

The invention discloses bath foam, in particular the bath foam which contains silk fibroin peptide-based surfactant, and belongs to the technical field of daily chemicals. The bath foam comprises the following components: silk fibroin peptide-based surfactant, surfactant alkyl polyglucosides, dodecane glycine betaine, humectant, electrolyte and the like. In the silk fibroin peptide-based surfactant, an aliphatic chain is used as a hydrophobic group, a silk peptide chain is used as a hydrophilic group, and the aliphatic chain and the silk peptide chain are connected through an amido bond; a preparation method for the bath foam comprises the following steps of: preparing silk fibroin by using natural bave, and performing hydrolysis to obtain silk fibroin peptide of which the molecular weight is 300 to 3,000; and reacting silk fibroin and fatty acyl chloride. The bath foam can effectively improve skin nutrition, enhance the viability and elasticity of skin cells, and promote metabolism of cells. The obtained product is safe and environment-friendly, is high in biodegradability and can meet the requirement of environment-friendly chemistry.

Description

technical field [0001] The invention relates to a body liquid cleanser, in particular to a bath liquid containing a silk peptide-based surfactant, and belongs to the technical field of daily chemicals. Background technique [0002] Body wash is a liquid cleanser for the body, mainly used for cleaning the skin of the whole body. It overcomes the shortcomings of high pH value of soap, easy to cause skin dryness and degreasing, and less foam, so it is loved by consumers and has gradually replaced soap as the first choice for people's body cleansers. [0003] The body wash is required to be safe, not to irritate the skin, and its residual substances cannot have side effects on the skin and human body. It has mild detergency, does not degrease, has moderate foam and is easy to rinse, and its pH value is close to that of the skin. From the point of view of the use of the main raw materials, the bath liquid has two kinds of soap-based bath liquid made of alkali metal soap made of ...
