dissociation constant
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is hydrolytically unstable (half-life less than 12 hours)

Description of key information

Lactide has a hydrolysis half-life of < 12 hours (3 hours); therefore, any dissociation behaviour is irrelevant and no study need to be conducted in accordance with Annex IX, point 7.16, column 2 of the REACH Regulation 1907/2006. The molecule does not contain any dissociable groups.

Key value for chemical safety assessment
