In cosmetics, knowing the name of an ingredient is not enough to confirm that it can be used in any formula.
The classification of a substance under the CLP Regulation can have consequences for its use in cosmetics. When a substance is classified as carcinogenic, mutagenic or toxic for reproduction —CMR—, the Cosmetic Products Regulation establishes as a general principle that it is banned, except for the exceptions provided for by law.
The update published through Regulation (EU) 2026/78, applicable since May 1, 2026, shows once again why you need to review more than the INCI name.
With every change it is worth checking the exact identity of the substance (name, CAS and EC number), its harmonized classification and the corresponding category, the updated annexes of the Cosmetics Regulation, and the date of application with its possible conditions or exceptions.
And an important clarification: CosIng is a useful tool for looking up names and functions, but appearing in the database does not in itself amount to an authorization for unrestricted use.
The name identifies. The regulatory framework determines how it can be used.
Because knowledge is part of the supply, too.
