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

Embodiment 1

[0079] The protein raw material adopts the leftover material of the tannery and evenly shaved leather shavings.

[0080] 1. Raw material pretreatment

[0081] (1) Picking, screening, and impurity removal;

[0082] (2) Soaking and cleaning:

[0083] It is carried out in a conical-bottom stainless steel tank equipped with agitator, water supply and drainage, and heating system. The amount of water added is based on submerging the treated raw materials, and at the same time, 2-3% of the raw material amount is added. In order to be able to remove the metal chromium ions in the chromium-containing leather shavings that may be mixed, sodium hydroxide and calcium oxide of 2-3% of the raw material amount should be added at the same time. Heat the temperature to 80-90°C, soak for 4 hours, and start the stirrer every half hour to stir for 5 minutes. After standing still for 1 hour, open the cone bottom valve to discharge water and sediment.

[0084] (3) Double enzyme hydrolysis:

Abstract

The invention discloses a protein-based surfactant used for skin and hair cleaning and care and a preparation method thereof, comprising the following steps: (1) pretreating natural protein raw materials; (2) preparing the pretreated natural protein raw materials Alkaline protease and catalase are added to carry out enzymolysis and enzyme inactivation to obtain an enzyme-inactivating protein hydrolyzate; (3) purify and purify the enzyme-inactivating protein hydrolyzate, then remove the water and dry to obtain collagen (4) Using the microreactor as a reaction device, the collagen and diethanolamine are subjected to amidation reaction to generate collagen polypeptide amide; then the collagen polypeptide amide is esterified with lauric acid to prepare a protein-based surfactant. The invention uses natural protein that is easily discarded or low-level utilization as raw materials to produce a functional protein-based surfactant suitable for cleaning and caring for skin and hair and other special needs, thereby improving the utilization efficiency of natural protein resources.

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,...
