INCI: Sodium laureth sulfate

What is Sodium laureth sulfate?

Sodium laureth sulfate is an anionic surfactant. It is formed by ethoxylation of dodecyl alcohol, obtained from coconut oil or palm kernel oil. It is commercially used in many personal care products.

Use & Benefits:

Function: Sodium laureth sulfate functions as a surfactant, emulsifying, foaming, and cleansing agent.

Surfactant: As a surfactant, it lowers the surface tension between two components of the product like two liquids or a liquid and a solid. It contains a hydrophilic and hydrophobic end. It attracts dirt, oil, and other impurities accumulated on the surface of the skin which then can be washed off easily with water.

Foam-Forming: Its foam-forming property makes it a useful ingredient in shampoos. It helps to keep the scalp clean and enhance the growth of healthy hair.

Emulsifier: As an emulsifier, it gives stability to the product. The product with oil and water-based components gets separated into its components. The emulsifier stabilizes the product, prevents separation of the components, and enables even distribution of the product components when used.

Products: It is used in the formulations of shampoos, bath products, facial cleansers, and other skin and hair care products.
