PEI-10
Synthetic Polymer
PEI-10 is a synthetic polyethyleneimine polymer used to increase or decrease the viscosity of cosmetic formulations. Ingredient-specific cosmetic safety data are limited, and polyethyleneimine polymers may be irritating depending on molecular weight, concentration, and formulation. Its synthetic polymer structure may also raise environmental persistence concerns.

How to read this rating
This rating reflects the Oh Daisey ingredient standard and the evidence currently available for cosmetic use. Product safety can also depend on concentration, exposure route, formulation, manufacturing quality, and individual sensitivity.
