Protein-based surfactant for carrying out cleaning care on skin and hairs and preparation method thereof

Abstract

The invention discloses a protein-based surfactant for carrying out cleaning care on skin and hairs and a preparation method thereof. The preparation method comprises the following steps: (1) pretreating a natural protein raw material; (2) adding alkaline protease and catalase into the pretreated natural protein raw material, and carrying out enzymolysis and enzyme deactivation, thus obtaining anenzyme deactivation protein hydrolysate; (3) purifying and refining the enzyme deactivation protein hydrolysate, removing moisture, and drying, thus obtaining collagen; (4) carrying out amidation reaction on the collagen and diethanolamine by taking a microreactor as a reaction device, and generating collagen polypeptide amide; carrying out esterification reaction on the collagen polypeptide amideand lauric acid, thus preparing the protein-based surfactant. According to the protein-based surfactant and the preparation method, disclosed by the invention, the functional protein-based surfactantwhich is suitable for cleaning the skin and the hairs and for other special demands can be produced by using natural protein which can be easily abandoned or lowly utilized as a raw material, so thatthe utilization efficiency of a natural protein resource is increased.

Description

technical field [0001] The invention relates to the technical field of skin and hair care products, in particular to a protein-based surfactant used for skin and hair care and a preparation method thereof. Background technique [0002] In the process of people's life and work, the skin and hair not only often come into contact with chemical and physical dirt, but also secrete and excrete metabolites. Only by removing these substances in time can the normal physiological functions of the skin be maintained and the human body feel comfortable. , so cleaning and caring for skin and hair is a regular thing to do, which plays an important role in eliminating fatigue, preventing diseases, improving health and improving labor efficiency. [0003] People mainly use fatty acid soap or cleaning agent to clean skin and hair. Due to the high efficiency and convenience of cleaning agent, it has become more and more popular among the public. Therefore, there are many brands on the market,...

Problems solved by technology

The problem with this route is that the reaction is also carried out at the interface between water and solvent, and the mass transfer efficiency is very low. In order to maintain the alkaline condition of the reaction system, it is necessary to adjust the pH value by dripping lye at any time. In order to avoid hydrophobic groups Side reactions such as hydrolysis occur, and can only react at room temperature, so the reaction speed is very slow
