TEA-Lauryl Sulfate (Tainolin AST-40) – Foaming Surfactant for Shampoo & Body Wash

TEA-Lauryl Sulfate (Tainolin AST-40) is the surfactant behind the lather — the ingredient that turns a simple liquid into a rich, foaming cleanser that feels satisfying to use and effective in action. An anionic surfactant formed from Triethanolamine and Lauryl Sulfate, it delivers the kind of abundant, stable foam that consumers associate with a genuinely cleansing product, while simultaneously lifting oils, dirt, and buildup from skin and hair with impressive efficiency.

Its balanced performance profile makes it a workhorse ingredient across the personal care spectrum. In shampoos, it cuts through scalp sebum and product buildup without stripping. In body washes, it creates the luxurious lather that makes a shower feel indulgent. In face washes, it provides thorough cleansing that rinses clean without residue. For formulators who need reliable, high-performance cleansing with excellent foam characteristics, Tainolin AST-40 is a dependable foundation to build on.

Formulation Tips

Combine with mild co-surfactants such as Cocamidopropyl Betaine (CAPB) or glucosides to reduce potential harshness and improve skin compatibility — this is standard practice in premium cleansing formulations. Add conditioning agents (e.g., cationic polymers, panthenol) to balance the cleansing action and leave skin or hair feeling soft post-rinse. Adjust pH to the 5.5–7.0 range for optimal skin compatibility. Works well in both transparent and opaque formulations.
