Tea-Lauryl Sulfate, also known as Triethanolamine Lauryl Sulfate, is an anionic surfactant commonly used in cosmetics and personal care products. It acts as a cleansing and foaming agent in different formulations. Tea-Lauryl Sulfate helps in removing dirt, oils, and impurities from the skin and hair by reducing the surface tension of water, allowing for effective cleansing. Additionally, it contributes to the formation of rich and stable foam, enhancing the sensory experience during product use. Tea-Lauryl Sulfate is generally found in shampoos, body washes, facial cleansers, and other cleansing formulations. The chemical formula of Tea-Lauryl Sulfate is C18H40NO7S.

What is TEA-LAURYL SULFATE used for?

Tea-Lauryl Sulfate finds applications in both skin and hair care products due to its surfactant properties.
  • Hair care: It is added to hair care products as it creates a rich and luxurious texture, making it easier to distribute and cleanse the hair and scalp. This ingredient also helps in removing product buildup, excess oils, and pollutants, leaving the hair feeling clean and revitalized
  • Facial care: It is used in products like cleansers, body washes, and facial cleansers as it is a great cleansing as well as a foaming agent, aiding in the removal of dirt, oils, and impurities from the skin, leaving it feeling clean and refreshed.

Tea-Lauryl Sulfate is made by the reaction between lauryl alcohol and triethanolamine, forming an intermediate compound. This compound is then sulfated by treating it with sulfuric acid, resulting in the final Tea-Lauryl Sulfate product. The sulfation step introduces a sulfate group into the molecule, which gives Tea-Lauryl Sulfate its surfactant properties.
