Polyquaternium-68 ●
TL;DR. This ingredient is a cationic film-forming and conditioning polymer used mainly in hair products for hold, anti-frizz control, combability, and a smoother feel.
What does Polyquaternium-68 do in a cosmetic formula?
This ingredient is a cationic film-forming and conditioning polymer used mainly in hair products for hold, anti-frizz control, combability, and a smoother feel.
Is Polyquaternium-68 clean?
From a clean-beauty perspective, it has friction because it is a synthetic quaternized polymer rather than a simple biodegradable conditioner. It is generally used for performance rather than skin nourishment, with low direct irritation expected in rinse-off or styling use but more scrutiny around persistence and polymer residues.
Is Polyquaternium-68 sustainable?
This material is synthetically produced from petrochemical-derived monomers and is not considered readily biodegradable. Its water-soluble polymer profile creates environmental persistence concerns, especially for rinse-off hair care.
Is Polyquaternium-68 COSMOS-approved?
It is not permitted under COSMOS-organic or COSMOS-natural standards as a conventional synthetic cationic polymer. It aligns weakly with Green Chemistry principles because it relies on nonrenewable feedstocks and has limited biodegradability, even though it can provide strong performance at low use levels.
How does Polyquaternium-68 work chemically?
The molecule is a high-molecular-weight, water-soluble cationic copolymer with permanently charged nitrogen-containing groups that bind well to negatively charged hair surfaces. It is commonly used at low percentages in gels, mousses, sprays, and conditioners, and it is generally stable across typical cosmetic pH ranges when formulated with compatible surfactants and electrolytes.
