Ceteth-20 Phosphate
Ceteth-20 Phosphate is the phosphate ester of PEG-20 cetyl ether that becomes anionic in water as pH rises. It's used as a co-emulsifier for mildly acidic to neutral formulas, improving stability, cleansing, and salt tolerance.

Our take
Is Ceteth-20 Phosphate a Good Ingredient?
Effective pH-responsive co-emulsifier for acidic to neutral systems with reliable performance. Can be mildly irritating in low-pH or exfoliant formulas, and as an ethoxylated material it relies on tight impurity controls. Consistent, low-risk performance is enough for Good, though not the strongest tier.
What it does
Skin Benefits
Performs well in low-pH systems, supporting clarity and a clean, refreshed after-feel. Supports emulsion stability in formulations sensitive to salts or acids.
Where you'll find it
Uses in Skincare & Cosmetics
Used in AHA/BHA lotions, exfoliating gel-creams, and low-pH facial cleansers. Also found in fluid moisturizers for smooth, uniform application.
Before you use it
Safety
May cause mild skin or eye irritation, especially in acidic systems. Trace ethoxylation residues are typically kept very low by reputable suppliers. Introduce gradually if you have sensitive skin.
