Product Description
Sodium dodecyl sulfate is an anionic surfactant, white to yellowish solid (can be divided into needle or powder), easily soluble in water, and anion, non-ionic combination is good, with good emulsification, foaming, penetration, decontamination and dispersion properties. Widely used in pharmaceutical, paper making, building materials, chemical industry, textile, oil extraction, cosmetics, detergent, toothpaste, shampoo, washing powder, plastic mold lubrication and other industries.
Main use
1, in cosmetics, skin care products are mainly used as a foaming agent, cleaning agent, wetting agent (make cosmetics contact with the skin as soon as possible, avoid being blocked by the skin oil), relatively safe, no acne-causing;
2, as detergent, textile bleaching AIDS and carpet dyeing agent;
3, wool detergent;
4, leather softening agent;
5, used as toothpaste, fire extinguisher blowing agent;
6. Used as cooking penetrant in papermaking;
7, oil Wells, mine fire extinguishing agent;
8. Emulsifier for emulsion polymerization of styrene butadiene and propylene acid;
9. Emulsifier of synthetic resin;
10. Flotation agent for metal beneficiation;
11. Biochemical analysis, ion pair reagent;
12, used as an anionic surface penetrant in pesticides, generally added in water-soluble pesticides in the amount of 0.1-0.3%, can significantly increase the leaf absorption of drugs;
13, used for mortar admixture, can play a water reduction, increase workability, water retention;
14, the production of cement as a grinding aid;
15, as a surfactant in the coating industry, it can reduce the surface tension of the coating, so that the coating is better distributed on the surface of the object;
18, aluminum alloy in the oxidation process, adding sodium dodecyl sulfate solution can reduce the surface tension, so that oxidizer molecules more easily contact the metal to make the reaction closer;
20, sodium dodecyl sulfate is a commonly used pharmaceutical excipients, it is an anionic surfactant, can be used as a solvent, emulsifier, skin penetrating agent, tablet and capsule lubricant, wetting agent, etc.
