2,3-EPOXYPROPYLTRIMONIIUM CHLORIDE (glycidyltrimethylammonium chloride)

Official label name (INCI name, EU glossary of cosmetic ingredient names), No 154

2,3-EPOXYPROPYLTRIMONIIUM CHLORIDE (glycidyltrimethylammonium chloride): Prohibited in cosmetics (Annex II, entry 1473), under Regulation (EC) No 1223/2009.

In plain words

What the rules say

It is prohibited to use it in a cosmetic product sold in the European Union, whatever the dose. If it appears on the ingredient list of a recent product, this needs checking: the record may be old or wrong, or the product intended for another market.

Hazard and risk

The CLP Regulation classifies this substance as carcinogenic, category 1B (presumed effect, established mainly from animal studies), mutagenic (may damage DNA), category 2 (suspected effect, without enough evidence for a higher category) and toxic for reproduction, category 2 (suspected effect, without enough evidence for a higher category).

This classification describes what the substance can cause (a hazard), not what happens when using a product (a risk): the risk depends on the dose, the form and the route of exposure (skin, inhalation, ingestion).

Already prohibited in cosmetics (Annex II).
