Frequently Asked Questions
What is Yellow 5 aluminum lake?
FD&C Yellow 5 Aluminum Lake is the insoluble aluminum lake of FD&C Yellow 5 (tartrazine, CAS 1934-21-0), supplied as a yellow colorant. The lake form is water-insoluble, unlike the parent dye.
What is the difference between a lake and a dye?
A soluble dye dissolves and can migrate or bleed in a formulation, while a lake is the dye precipitated onto an insoluble substrate (here, alumina) so it disperses as a pigment rather than dissolving. Lakes are chosen for oil-based and dispersion systems where a soluble dye would bleed.
What is Yellow 5 aluminum lake used for?
It is used as an insoluble yellow colorant in cosmetic and personal-care formulations, including hair-coloring applications, and in oil and dispersion systems. Suitability for any specific end use is the formulator's determination.
What is the CAS number and HS code?
The parent FD&C Yellow 5 (tartrazine) is CAS 1934-21-0; the lake is classified under HS 3205.00 (color lakes). Reference these on RFQs and customs documentation.
What bulk packaging and documentation are available?
Supplied as a powder lake for industrial and personal-care coloring; request a bulk quote for available pack sizes and order quantities. An SDS and Certificate of Analysis accompany each shipment.
What is the REACH and TSCA regulatory status of FD&C Yellow 5 Aluminum Lake (Tartrazine Aluminum Lake)?
FD&C Yellow 5 Aluminum Lake (Tartrazine Aluminum Lake) (CAS 1934-21-0) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 217-699-5).
