Ceteth-20 Phosphate ●
TL;DR. This ingredient functions mainly as an anionic emulsifier and surfactant, helping water and oil form stable creams, lotions, and cleansing systems. It can also support dispersion and improve texture in emulsions.
What does Ceteth-20 Phosphate do in a cosmetic formula?
This ingredient functions mainly as an anionic emulsifier and surfactant, helping water and oil form stable creams, lotions, and cleansing systems. It can also support dispersion and improve texture in emulsions.
Is Ceteth-20 Phosphate clean?
From a clean-beauty perspective, it carries friction because it is ethoxylated, which means manufacturing controls are needed for residual ethylene oxide and 1,4-dioxane. It is generally usable in conventional formulas, but it is not a low-controversy choice for stricter clean frameworks.
Is Ceteth-20 Phosphate sustainable?
This material is typically made from a fatty alcohol source combined with petrochemical-derived ethoxylation chemistry and phosphorylation. Its biodegradation profile is less straightforward than simple fatty alcohols or plant oils, so it is not a strong sustainability fit.
Is Ceteth-20 Phosphate COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic standards because ethoxylated materials are generally outside the standard. From a Green Chemistry lens, the petrochemical processing step and residue-management burden weaken its profile despite its useful emulsifying performance.
How does Ceteth-20 Phosphate work chemically?
The molecule combines a C16 lipophilic chain, roughly 20 oxyethylene units, and an ionizable it head, giving it strong oil-water interfacial activity. It is commonly used at low single-digit percentages in emulsions and performs best when the formula pH and electrolyte load are managed for emulsion stability.
