Helps keep oil and water blended while adding mild cleansing power.

Our take
Is Trideceth-6 Phosphate a Good Ingredient?
It rates Good due to reliable oil-in-water emulsification and mild anionic cleansing that helps stabilize textures without a heavy feel. It works well alongside other surfactants to maintain uniformity in complex systems, though it's a support ingredient rather than an active.
