Our take
Is Trideceth-9 a Good Ingredient?
It rates Good because it provides effective solubilization and wetting for clear, even-textured formulas with generally mild nonionic surfactant action. It improves spread and wash-off without significant residue, but offers no treatment benefit of its own.
