Conclusion on classification
(3 -chloro-2-hydroxypropyl)trimethylammonium chloride (CHPTAC) is classified in the 31st ATP of Annex I of EU Directive 67/548/EEC as:
R52/53: Harmful to aquatic organisms, may cause long-term adverse effects in the environment.
This classification was determined on the basis of its potential conversion to the related substance 2,3-epoxytrimethylammonium chloride (EPTAC) in the environment.
