Also known as

Quaternized Hydroxyethylcellulose Cellulose, 2-hydroxyethyl, reaction product with trimethylammonium chloride JR-400 Ucare Polymer JR HEC Quat

Compatibility

Works well with:
Glycerin Panthenol Hydrolyzed Keratin Dimethicone Cetrimonium Chloride Behentrimonium Methosulfate

Use caution with:
High-molecular-weight anionic polymers Carbomer Sodium Lauryl Sulfate

As a cationic polymer, Polyquaternium-10 can form complexes or precipitates when combined with anionic polymers such as Carbomer or high concentrations of anionic surfactants like Sodium Lauryl Sulfate, leading to turbidity or phase separation. It is best used alongside nonionic or other cationic ingredients. In rinse-off formulas, pairing with mild anionic surfactants at balanced charge ratios can work if carefully optimized.

Formulation notes

Polyquaternium-10 is a cationic cellulose-derived polymer widely used in shampoos, conditioners, and leave-on hair care products to deposit a conditioning film on hair and skin, reducing static, improving combability, and imparting a smooth feel. Its positive charge allows substantive adsorption onto negatively charged hair and skin surfaces, especially effective in rinse-off applications where other conditioning agents wash away. It is generally considered safe and well-tolerated; however, formulators should avoid combining it with strongly anionic ingredients to prevent formulation instability.
