Sodium lauryl polyoxyethylene ether sulfate, also known as sodium dodecyl ether sulfate sulfonic acid, is a colorless or gray gel at normal temperature and pressure, with a certain degree of moisture absorption. Sodium lauryl polyoxyethylene ether sulfate is an anionic surfactant, which is often used as basic chemical raw material, detergent and Textile manufacturing in industry. This compound has good foaming performance, clean profile, and can be used as a biodegradable surfactant.

Application
As an anionic surfactant, sodium lauryl polyoxyethylene ether sulfate is easily soluble in water and can effectively resist hard water. It has excellent detergency, emulsification, and foaming properties, and mild washing properties that do not damage the skin. Therefore, this chemical is commonly used in the production of personal care products such as soap, shampoo, shower gel, hair conditioner, toothpaste, etc. because it has good cleaning ability and emulsification performance. It should be noted that although this compound has good cleaning and emulsifying properties, long-term use may cause irritation and dryness to the skin. Therefore, the correct dosage and usage method should be when using. In textile processing, it is often necessary to use surfactants to improve the contact angle between fabric and water, making it easier to wet and improve dyeing and printing effects. Sodium lauryl polyoxyethylene ether sulfate has good surface activity properties, which can enhance water permeability and adsorption, and promote the penetration and diffusion of dyes and additives. In addition, it can also serve as a clarifying agent to remove impurities and grease on the surface of fabrics, improving their cleanliness and dyeing uniformity. 
Storage conditions
At high temperature (above 50 ℃) or in acid (pH=5) environment, sodium lauryl polyoxyethylene ether sulfate may produce Decomposition, which is due to hydrolysis of alkyl ether sulfate. Given that alkyl ether sulfates are easily hydrolyzed at high temperatures, this product should be avoided from being stored in environments above 50 ℃.
