preparation example Construction

[0028] The present invention also provides the preparation method of above-mentioned composite surfactant, it comprises the following steps:

[0029] S1: Take PEG-20 glyceryl laurate in a blender and stir at a low speed;

[0030] S2: Then add polyglyceryl-10 laurate under high speed stirring.

[0031] As a preferred solution, the stirring speed of the low-speed stirring in step S1 is 100-200 r / min, and the stirring time is 30-50 min.

[0032] As a preferred solution, the stirring speed of the high-speed stirring in step S2 is 2000-2500 r / min, and the stirring time is 20-30 min.

[0033] The present invention also provides the application of the above composite surfactant, which is used in body care products.

[0034] As a preferred solution, the body care products include cleansing water, cleansing mask, facial cleanser, shampoo, shower gel or hair conditioner, the amount of the composite surfactant is 1-10 by weight %.

Abstract

The invention discloses a composite surfactant. The composite surfactant is prepared from PEG-20 glyceryl laurate and polyglycerol-10 laurate, and is specifically prepared from the following components in percentage by mass: 30-50% of the PEG-20 glyceryl laurate and 50-70% of the polyglycerol-10 laurate. The invention further discloses a preparation method and application of the composite surfactant. Compared with the prior art, the composite surfactant has the advantages that the antibacterial effect is achieved, the functions of skin moistening, solubilizing, emulsifying and the like are integrated, and the composite surfactant is compatible with a cationic surfactant, an anionic surfactant and other nonionic surfactants, so that the application range is wide.

Description

technical field [0001] The invention relates to the technical field of personal cleaning and care products, and more specifically relates to a composite surfactant and its preparation method and application. Background technique [0002] Surfactant refers to a substance that can change the interface state of its solution system by adding a small amount. With fixed hydrophilic and lipophilic groups, it can be aligned on the surface of the solution. The molecular structure of surfactants has amphiphilicity: one end is a hydrophilic group, and the other end is a hydrophobic group; the hydrophilic group is often a polar group, such as carboxylic acid, sulfonic acid, sulfuric acid, amino group or amino group and Its salts, hydroxyl groups, amide groups, ether bonds, etc. can also be used as polar hydrophilic groups; while hydrophobic groups are often non-polar hydrocarbon chains, such as hydrocarbon chains with more than 8 carbon atoms. Surfactants are divided into ionic surfac...
