Corrections to California Safe Cosmetics Program Reportable Ingredients List

The California Safe Cosmetics Program (CSCP) announced corrections to CSCP’s Reportable Ingredients List. The corrections update chemical listings from 23 source authoritative lists.

In addition to the changes listed below, the instructions for reporting Fragrance Allergens in the “Legend for When to Report” in the second tab of the downloadable spreadsheet was updated. The updated language clarifies that Fragrance Allergens must be reported regardless of their intended purpose in the product—to clarify, they must be reported even if they are not used to impart scent or counteract odor.
