Science
Mechanism of Action
This ingredient functions as a cationic polymer, meaning it carries a positive electrical charge. This characteristic enables it to form ionic bonds with negatively charged sites present on surfaces like hair and, potentially, the skin, thereby providing a conditioning effect. Beyond this bonding, it contributes to moisture retention and forms a protective film. However, the most extensively documented applications for Polyquaternium-70 revolve around enhancing hair manageability, softness, shine, and volume, along with delivering anti-static and detangling benefits.

- As a cationic polymer, Polyquaternium-70 may complex with anionic surfactants, which is a key consideration in formulations such as conditioning shampoos to maintain product stability and performance.
Safety
Safety Profile
Polyquaternium-70 has not been reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. However, available third-party assessments indicate a low risk for irritation of the skin, eyes, or lungs, with some sources classifying it as 'Irritant Free'. Data concerning skin allergies, developmental and reproductive toxicity, or carcinogenicity are currently unavailable.
