Frequently Asked Questions

What is D&C Red No. 7?

D&C Red 7 is the calcium salt of Lithol Rubine B, a synthetic monoazo pigment (CAS 5281-04-9; C.I. Pigment Red 57:1; formula C18H12CaN2O6S). It is supplied as a red colorant for industrial use.

What is the difference between D&C and FD&C?

The prefixes describe the permitted use category of a colorant rather than its chemistry: FD&C-class colors are designated for foods, drugs, and cosmetics, while D&C-class colors are designated for drugs and cosmetics only. D&C Red 7 carries the D&C designation. We supply the pigment; intended-use compliance is the buyer's responsibility.

What is D&C Red 7 used for?

It is used as a red pigment for plastics (PVC, polyolefins, ABS, PET, and styrenics) and as a cosmetic colorant. In polymer compounding it is run as a masterbatch pigment, with typical loadings near 2%.

What is the CAS number and HS code for bulk orders?

D&C Red 7 calcium salt is CAS 5281-04-9 (C.I. Pigment Red 57:1), classified under HS 3204.17. Reference these on RFQs and customs paperwork to ensure correct identity and tariff treatment.

What bulk packaging and documentation are available?
