A CAS Registry Number (also referred to as CAS RN or informally CAS Number) is a unique identification number assigned by the Chemical Abstracts Service (CAS), US to every chemical substance described in the open scientific literature. It inclu ...
and an INCI name is not always one-to-one. In some cases, more than one INCI name may have the same CAS number, or more than one CAS number may apply to an INCI name. For example, the CAS number 1245638-61-2 has the CA Index Name of 2-Propenoic acid, reaction products with pentaerythritol. This CAS number can accurately be associated with two INCI names: Pentaerythrityl Tetraacrylate and Pentaerythrityl Triacrylate. Alternatively, the INCI name, Glucaric Acid can be associated with two CAS numbers: 87-73-0 which has the CA Index Name of D-Glucaric acid, and 25525-21-7, which has the CA Index Name of DL-Glucaric acid. Both of these examples are accurate associations between CAS and INCI.[Personal Care Products Council - Background information on INCI and CAS](_blank)

INCI labeling
In the U.S., under the Food, Drug, and Cosmetic Act and the Fair Packaging and Labeling Act, certain accurate information is a requirement to appear on labels of cosmetic products.
/ref> In Canada, the regulatory guideline is the Cosmetic Regulations. Ingredient names must comply by law with EU requirements by using INCI names.
The cosmetic regulation laws are enforceable for important consumer safety. For example, the ingredients are listed on the ingredient declaration for the purchaser to reduce the risk of an allergic reaction to an ingredient the user has had an allergy to before. INCI names are mandated on the ingredient statement of every consumer personal care product. The INCI system allows the consumer to identify the ingredient content. In the U.S., true soaps (as defined by the FDA) are specifically exempted from INCI labeling requirements as cosmetics per FDA regulation.
