1,1,1,3,5,5,5 -Heptamethyltrisiloxane (H-L3) hydrolyses to
trimethylsilanol and methylsilanetriol with a hydrolysis half-life of
greater than 48 hours. Therefore, the environmental hazard assessment is
based on the properties of the parent substance in accordance with REACH
guidance for Chemical Safety Assessment.
Trimethylsilanol and methylsilanetriol are
the final products of hydrolysis reactions under the normal range of
conditions of pH and temperature. However, other biotic or abiotic
reactions may proceed over longer time-scales in the environment.
