Quaternium-73 (CAS 15763-48-1), also called Pionin, is the ingredient identified in ZLEY®’s published technical data sheet (TDS). It is not a polyquaternium conditioning polymer. The TDS specifies a yellowish to yellow crystalline powder and an HPLC purity of at least 98%.
The supplier suggests 0.001–0.05% use and recommends predissolving the raw material in ethanol, butanediol or glutarediol before incorporation. This range is supplier guidance, not a universal regulatory limit or a guarantee of finished-product efficacy. Check the current TDS, target-market rules, compatibility and skin tolerance for the complete formula.
For an explanation of the name confusion and buyer checks, read our Quaternium-73 naming and formulation guide. Request the current COA, TDS and SDS before ordering.
