The relationship between a CAS Registry Number 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.

A number of studies have shown that prolonged exposure to very high doses of TBHQ may be carcinogenic, [7] especially for stomach tumors. [8] Other studies, however, have shown opposite effects including inhibition against HCA -induced carcinogenesis (by depression of metabolic activation) for TBHQ and other phenolic antioxidants (TBHQ was one ...
