Frequently Asked Questions

What is Quaternium-87 made of?

Quaternium-87 (CAS 90383-16-7, INCI Quaternium-87) is an imidazolium ester quat carrying mixed C9-C19 alkyl chains. It is a cationic conditioning surfactant within the cationic surfactant family, with formula reported as C15H17NO for the base structure.

What is Quaternium-87 used for in hair products?

It is used as a conditioning and antistatic agent in hair care. Quaternium-87 improves combability and softness in rinse-off and leave-on products and serves as a cationic active in detangling, conditioner, and mask systems.

Is Quaternium-87 a silicone?

No. Quaternium-87 is an imidazolium ester quaternary ammonium compound, not a silicone. It delivers cationic conditioning through its quaternary nitrogen and alkyl chains rather than through a silicone backbone.

What CAS number and HS code apply to Quaternium-87?

It is supplied under CAS 90383-16-7 and classified under HS heading 3402.41 (cationic organic surface-active agents). Confirm the final import classification with your customs broker for your destination market.

What is the cost of bulk Quaternium-87 and how is it packaged?

Pricing depends on volume and market conditions, so RawSource quotes per order rather than listing a fixed price. Request a bulk RFQ with your required quantity to receive pack sizes, MOQ, lead time, and a CoA/SDS.
