FD&C colors: why approved colours are better
The commercial and regulatory case for certified colour additives: who regulates them where, what batch certification buys you, and what unapproved colour costs.
Whether you work in food, beverages, pharmaceuticals or cosmetics, colour additives come with regulatory obligations. Colour makes products recognisable and appealing, and it is one of the most tightly controlled ingredient classes there is, because everything coloured is eventually eaten, swallowed or worn.
Organic and inorganic: getting the terms right
Worth settling first, because the everyday meaning of "organic" (a farming and food-labelling standard) is unrelated to the chemical one.
In colour chemistry, organic means carbon-based. That covers the synthetic dyes and lakes (azo reds, xanthenes, triarylmethanes, indigoids), and it also covers naturally derived colourants such as carmine and beta-carotene. Inorganic means mineral: iron oxides, titanium dioxide, ultramarines, chromium oxide greens.
The Colour Index encodes exactly this split. Codes below CI 77000 are organic; codes from CI 77000 upward are inorganic. So the claim that organic colours are extracted from mineral sources has it precisely backwards: minerals give you inorganic pigments. Feedstock is a separate question from chemical class: most synthetic organic colourants today are petrochemical in origin, but that says nothing about their classification. See how to read a CI number.
How safe are colour additives?
Colour additives have attracted public debate for decades, and the honest position is specific rather than sweeping. Problems arise in two circumstances: when unapproved colourants are used, and when approved ones are used beyond their permitted concentrations or outside their permitted applications. Unapproved industrial dyes used as food colour have caused genuine harm, and adulteration cases still surface.
Approved colourants used within their listings have been through toxicological review establishing acceptable daily intakes. Individual sensitivity exists (some people react to particular colourants, and certain azo dyes carry warning-label requirements in the EU), but that is a matter of specific substances rather than a verdict on the class.
Who regulates what, where
There is no single global list, which is the practical complication.
- United States: the FDA administers colour additive listings under 21 CFR Parts 73, 74 and 82, with batch certification required for FD&C, D&C and External D&C colours.
- European Union: cosmetic colourants are listed in Annex IV of Regulation (EC) No 1223/2009; food colours are regulated separately under Regulation (EC) No 1333/2008 with E numbers.
- India: the FSSAI regulates food colours; cosmetics fall under the Drugs and Cosmetics Act and BIS standards.
- Japan, China, Korea and others maintain their own positive lists.
These lists differ. A colourant permitted in one market may be prohibited in another, or permitted at a different level or for a different application. Labelling requirements (declaring the additive and, in some cases, its quantity) vary too.
Why use approved colours
Documented safety and traceability. An approved colourant has a toxicological dossier behind it, and a certifiable one carries a batch certification lot number giving verified identity and purity. Where a supplier cannot produce that documentation, you have no idea what you have bought.
Consumer safety and reputation. The wrong colourant in a product applied to skin or eaten can cause real harm, and the consequences reach far beyond a single batch. Reputational damage outlasts a recall by years.
Regulatory and commercial risk. Unapproved colour additives are grounds for product recall, import refusal and enforcement against the manufacturer, up to loss of licence. Because colour is rarely tested at border inspection until something goes wrong, the cost typically lands after launch, the most expensive point at which to discover it.
Market access. Retailers and distributors increasingly require full documentation before listing. Approved colour with certification lot numbers is what makes that straightforward.
Use only colourants approved for the specific market and application you are selling into, and keep the certification documentation with the specification. It is better for consumers and materially cheaper for the business.
Frequently asked
Are organic colours extracted from minerals?
No, and this is a common inversion. In chemistry, organic means carbon-based: the synthetic dyes and lakes, listed below CI 77000. Inorganic colourants are the minerals and metal oxides: iron oxides, titanium dioxide, ultramarines, listed at CI 77000 and above.
Do the same colours get approved everywhere?
No. Positive lists differ substantially between the US, EU, Japan, India and other markets, and so do permitted concentrations and applications. A colour routine in one market may be prohibited in another, so formulate to the list of every market you sell into.
What does batch certification give a buyer?
Traceable identity. Each lot of a certifiable colour is submitted to the FDA, tested against identity and purity specifications, and issued a certification lot number that follows the material through the supply chain.
