Polyquaternium 72 ●
TL;DR. This ingredient is used mainly as a cationic conditioning polymer and film-former in hair care. It helps improve wet and dry combing, reduce static, and leave a light deposited film on hair fibers.
What does Polyquaternium 72 do in a cosmetic formula?
This ingredient is used mainly as a cationic conditioning polymer and film-former in hair care. It helps improve wet and dry combing, reduce static, and leave a light deposited film on hair fibers.
Is Polyquaternium 72 clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic quaternary polymer rather than a simple biodegradable conditioning agent. It is generally used at low levels, but clean frameworks often scrutinize this class for persistence and aquatic-impact concerns.
Is Polyquaternium 72 sustainable?
This material is typically petrochemical-derived and is not readily biodegradable. Its cationic polymer structure can bind to surfaces and wastewater solids, which raises environmental persistence concerns compared with simpler plant-derived conditioners.
Is Polyquaternium 72 COSMOS-approved?
It is not permitted under COSMOS-organic or COSMOS-natural standards. Its synthetic origin, limited biodegradability, and persistent polymer profile make it a weak fit with Green Chemistry preferences.
How does Polyquaternium 72 work chemically?
This compound is a high-molecular-weight, permanently cationic polymer with quaternary ammonium groups that adsorb strongly to negatively charged hair and skin surfaces. It is usually used at low active levels in rinse-off or leave-on conditioning systems, and performance depends on charge density, molecular weight, surfactant compatibility, and deposition behavior.
