Frequently Asked Questions

What is Polyquaternium-7 used for?

Polyquaternium-7 (CAS 26590-05-6) is used as a hair- and skin-conditioning, antistatic, and film-forming agent in personal-care formulations. It is compatible with anionic surfactant systems, so it is common in shampoos, conditioners, and body washes.

What is Polyquaternium-7 made of?

It is a cationic copolymer of acrylamide and diallyldimethylammonium chloride (DADMAC). That structure gives it cationic conditioning behavior plus film formation and improved slip in rinse-off cleansers.

Is Polyquaternium-7 compatible with anionic surfactant systems?

Yes. PQ-7 is formulated to remain compatible with anionic cleansing surfactants, which is why it is widely used in surfactant-based shampoos and body washes for conditioning and feel benefits.

Where can I buy Polyquaternium-7 in bulk, and how is it packaged?

RawSource supplies it in bulk as an aqueous solution, typically in drums, totes, or IBCs. Request a bulk quote with your target volume and packaging, and we will confirm availability along with the CoA and SDS.

What is the CAS number for Polyquaternium-7?
