CAS:  102-71-6 ASSAY : 85% Triethanolamine is found in skincare and cosmetic products such as moisturizers, eyeliners, mascaras, hair care, and sunscreens. It stabilizes and increases the pH of products to improve the way they feel and interact with the skin. Triethanolamine is also a non-active compound, which means it doesn’t have any effect on the skin; it’s only used to make products more stable and improve texture. Triethanolamine is also used as a corrosion inhibitor in metal-cutting fluids , a curing agent for epoxy and rubber polymers, as a copper–triethanolamine complex to control freshwater algae on lakes and ponds and as a neutralizer–dispersing agent in agricultural herbicide formulations.
