Is Cetyl Phosphate a Good Ingredient?

It reliably stabilizes oil-in-water emulsions and improves texture, with longstanding use and consistent performance in formulas. Generally low irritation at typical levels, though as an anionic surfactant it can be drying for very sensitive skin. Consistent, low-risk performance is enough for Good, though not the strongest tier.
