Science
Mechanism of Action
This ingredient functions by reducing the surface tension between immiscible phases, allowing them to blend effectively. As a derivative of polyethylene glycol (PEG) and stearate, its molecular structure enables it to stabilize emulsions, condition the skin, and contribute to cleansing properties by dispersing oils and dirt.

Dusting Analysis
There is no specific data available regarding 'dusting' or 'red flag percentages' for PEG-45 Stearate Phosphate in cosmetic applications.
The Formula
Formulation
Stability
While general PEGs exhibit good stability, no specific optimal pH range for PEG-45 Stearate Phosphate has been established. Formulators should consider the potential influence of the phosphate group on pH-dependent stability.
Conflicts
- Avoid use on compromised or damaged skin
- Requires careful monitoring to ensure minimal levels of impurities such as ethylene oxide and 1,4-dioxane
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed PEG Stearates, which include PEG-45 Stearate, safe for cosmetic use at concentrations up to 25%. Although PEG-45 STEARATE PHOSPHATE itself was not individually assessed, it is considered a safe derivative. This ingredient is generally well-tolerated and considered non-irritating. However, application to damaged skin should be avoided, and manufacturers must ensure low levels of potential impurities like ethylene oxide and 1,4-dioxane.
