説明Sodium dodecyl sulfate is an anionic surfactant, and is a typical representative of sulphate-based surfactant. It is abbreviated as SDS, and also known as AS, K12, coco alcohol sulfate, sodium lauryl sulfate and foaming agent. The commercial products are usually white to light yellow crystalline powder. It is non-toxic, slightly soluble in alcohol, insoluble in chloroform and ether, soluble in water, and has good anionic and nonionic complex compatibility. It has good emulsibility, foamability, and foaming, infiltrating, decontaminating and dispersing properties. It is abundant in foams and quickly biodegradable, and has solubility next only to fatty alcohol polyoxyethylene ether sodium sulphate (abbreviated as AES). It is not sensitive to alkali and hard water, but its stability is inferior to general sulfonate under acidic conditions and is close to AES. It is not favorable to exceed 95 °C upon long-term heating, and its irritation is at the middle level among surfactants, with an irritation index of 3.3 for a 10% solution, which is higher than AES and lower than sodium dodecyl benzene sulfonate (abbreviated as LAS). Toxicity LD50 is 1300mg/kg. There is no evidence that this product is carcinogenic, but high doses may indeed irritate the skin. However, in general sanitary products the concentration is limited when used as a forming agent, and is in line with national standards. So there is no need to concern. Sodium dodecyl sulfate is a major component of detergent. It is usually used in the DNA extraction process to separate DNA after protein denaturation. It is often misread as sodium dodecyl sulfonate. It is widely used as a foaming agent in toothpaste, soap, shower gel, shampoo, detergent and cosmetics. 95% of personal care products and household cleaning products contain sodium lauryl sulfate.The above information is edited by the chemicalbook of Jin Yinxue.

使用Sodium dodecyl sulfate is an emulsifier and whipping aid that has a solubility of 1 g in 10 ml of water. It functions as an emulsifier in egg whites. It is used as a whipping aid in marshmallows and angel food cake mix. It also functions to aid in dissolving fumaric acid.

一般的な説明White to pale yellow paste or liquid with a mild odor. Sinks and mixes with water.
