FD&C Red No. 3

FD&C Red No. 3 suppliers and sourcing guide

FD&C Red No. 3 (erythrosine) is a synthetic, water-soluble cherry-pink xanthene dye, principally the disodium salt of tetraiodofluorescein. Every batch must be certified by FDA. FDA has ordered its authorization for food and ingested drugs revoked, with reformulation deadlines in 2027 and 2028, so buyers sourcing it should plan replacement colors rather than new uses. It has been sold as straight dye powder and liquid solutions for candy, frostings and baked goods.

What to check on the COA

FDA certification lot number
Every batch of FD&C Red No. 3 must carry an FDA certification lot number; check that the number on the COA and the drum match.
Total color (pure dye)
Total color content, by spectrophotometry or titration, against the minimum in the 21 CFR part 74 specification; it sets how much dye each kilogram delivers.
Volatile matter, chlorides and sulfates
Sum of moisture (loss at 135 °C) and salts, which make up most of the non-dye portion of a straight color.
Subsidiary colors and intermediates
Subsidiary colors and unreacted intermediates by HPLC, each against its regulatory limit.
Heavy metals
Lead, arsenic and mercury by ICP-MS, reported against the limits in the color additive regulation and the supplier specification.
Water-insoluble matter
Insoluble residue after dissolving, which shows up as specks or haze in clear beverages.

Storage, lots and expiry

Storage and shelf life

Store in the original sealed containers in a cool, dry place away from light; powders are hygroscopic and cake in humid rooms, and dust should be controlled because small amounts stain other products. Shelf life is set by the supplier, and certified colors are generally retested for total color and appearance once past the supplier retest date. Keep each container's FDA certification lot number with the stock so it can be traced into finished batches.

Lots and expiry dates

Record the FDA certification lot number and total color for any lots still held, and track remaining stock against the FDA reformulation deadline for each product type. Retain shade standards so replacement colors can be matched.
