Triethanolamine lactate

Triethanolamine lactate (CAS 20475-12-1), also known as TEA-Lactate, is the salt formed by neutralizing triethanolamine with lactic acid. It functions as a pH buffer, humectant, and corrosion inhibitor across personal care, coatings, and industrial textile applications.

In cosmetic formulations, it conditions skin and hair while stabilizing product pH, making it a practical dual-function ingredient in lotions, creams, and leave-on treatments. Coatings and metalworking fluid formulators use it to inhibit corrosion.

It is used to maintain alkaline buffer stability in aqueous systems. Textile and leather processors incorporate it into finishing baths where controlled pH and mild hygroscopic action improve fiber handling and surface treatment outcomes.

Adhesive and sealant manufacturers use it as a neutralizing agent to adjust rheology and compatibility in water-based systems. This versatility makes it a staple in various chemical manufacturing sectors requiring precise pH control.

Triethanolamine lactate is typically supplied as a clear to pale yellow aqueous solution. It is available in technical and cosmetic-grade specifications, with cosmetic-grade material meeting purity requirements for personal care.

The material is suitable for both leave-on and rinse-off personal care formulations. Bulk supply is standard in intermediate and large drum quantities, with concentration levels varying by supplier and end-use requirement.
