I always suggest a review of regulations as the first step in selecting color additives for use in making cosmetics. Colorant regulations can limit the use to certain cosmetic applications and percentages and can also vary by the country in which the product is sold. I recently watched a formulator scramble to replace D&C Red 7 Lake in an eye shadow color at the last minute after realizing it’s not permitted for eye area use in the United States.
US Color Regulations
There are two important definitions to consider when interpreting the color additive regulations for cosmetics. These include the terms ‘cosmetic’ and ‘color additive.’ According the US Food and Drug Administration (FDA) the term cosmetic means
articles intended to be rubbed, poured, sprinkles or sprayed on, introduced into, or otherwise applied to the human body or any part thereof for cleansing, beautifying, promoting attractiveness, or altering the appearance and articles intended for use as a component of any such articles; except that term shall not include soap.
And the definition of color additive is
…any material, not exempted under section 201(t) of the Food, Drug, and Cosmetic Act, that is a dye, pigment or other substance made by a process of synthesis or similar artifice, or extracted, isolated, or otherwise derived, with or without intermediate or final change in identity, from a vegetable, animal, mineral or other source and that when added to a food, drug, or cosmetic or to the human body or any part thereof, is capable (alone or through reaction with another substance) of imparting color thereto.
In the United States, the permanent list of approved colors is divided into two categories.
Certifiable Color: The list of certifiable colors is comprised of synthetic, organic colorants. A sample of each batch of these additives must be sent to the FDA for analysis. If the batch meets required purity standards the FDA issues a certification number to the manufacturer. The manufacturer of the colorant must display the certification number on the label of the package in which the color additive is shipped and on all associated paperwork. In addition, the cosmetic company that purchases certified color additives must keep a record of where the batch of colorant was used in production.
Exempt Colors: Batch certification of exempt colors is not required, but purity specifications must adhered to by manufacturers and consumers of these colorants. This category is primarily comprised of inorganic pigments, but there are exceptions like carmine, which is the aluminum or calcium-aluminum lake on an aluminum hydroxide substrate of carminic acid.
The FDA’s website is a great resource for information on color regulations. The following will be useful:
