Sodium lauryl sulfate, referred to as SDS, also known as sodium lauryl sulfate, is an anionic surfactant with the chemical formula CHHh₂SsoNaNA and a relative molecular weight of 288.38.Sodium lauryl sulfate is odorless and has a slightly bitter taste. The substance is white or light yellow powder and needle-like crystals. Common forms include powder, needle-like crystals, and columnar particles. It can develop and produce colorful columnar products such as red, blue, green, orange, etc., breaking the pain points of traditional products that are gray in color and easy to clump.It is easily soluble in water, and a small amount of foam will be produced when dissolved. The aqueous solution is weakly alkaline, with a pH value of about 7.5-9.0, and has excellent surface activity, emulsification, foaming, decontamination and dispersion properties.It is easy to absorb moisture and agglomeration in the air. It decomposes when heated to 180℃, resulting in toxic gases. It needs to be sealed and stored in a cool and dry place, away from high temperature, open flame and strong oxidants to prevent moisture absorption and decomposition.In industrial production, it is used in cosmetics, detergents, medicine, chemicals, food and other fields, as an emulsifier, foaming agent, decontamination agent, dispersant, and also used in cosmetic manufacturing, detergent production, drug synthesis and other processes.Its excellent emulsifying and decontamination properties can enhance the product experience in the field of cosmetics and detergents, and can be used as a core additive in the chemical industry to assist the production of a variety of products. It is widely used and cost-effective. It is one of the most common surfactants in cleaning agents.
