Frequently Asked Questions

What is Polyquaternium-2 made of?

Polyquaternium-2 (CAS 68555-36-2) is a cationic polymeric quaternary ammonium compound of the polyurea ionene type. Its cationic backbone gives it substantivity to hair and skin in formulations.

Is Polyquaternium a silicone?

No. Polyquaternium-2 is a quaternary-ammonium (ionene) polymer, not a silicone (organosilicon) polymer. Silicone conditioning agents are a separate chemistry; if you need a silicone, ask about our silicone-fluid grades.

What is Polyquaternium-2 used for?

It is used in personal-care formulations as an antistatic and hair-conditioning agent and as a film former that deposits a conditioning film in rinse-off systems. Its cationic substantivity drives the conditioning effect.

How is Polyquaternium-2 supplied in bulk?

It is typically supplied as an aqueous solution with active content varying by grade. Confirm the active percentage on the CoA, request the SDS, and send your volume and packaging for a bulk quote.

What is the CAS number for Polyquaternium-2?

Its CAS number is 68555-36-2. A batch CoA and SDS are available on request for identity confirmation and incoming-material qualification.
