Additional information

(3-Chloropropyl)trimethoxysilane (CAS 2530-87-2) hydrolyses in water with a half-life of 4.5 hours at pH 7 and 20°C. This short hydrolysis half-life is such that the hydrolysis products, and not the parent substance, are relevant for environmental risk assessment.

Conclusion on classification

The substance has reliable short-term E(L)C50 values of >100 mg/l in fish, 869 mg/l in invertebrates and >833 mg/l in algae. It has reliable NOEC 167 mg/l in algae.

The substance hydrolyses (very) rapidly in water and is not readily biodegradable; the silanol hydrolysis product has low log Kow.

 

These data are consistent with the following classification under Regulation (EC) No 1272/2008 (as amended) (CLP):

Acute toxicity: Not classified.

Chronic toxicity: Not classified.
