No experimental data are available on the hydrolytic stability of the
category members Fatty Acids. Due to the ready biodegradability of the
category members, hydrolysis testing is not required. Based on
manufacturing experience with liquid cleaning products, it is known that
Fatty Acids are stable in water (SIDS, 2009).
Based on EPI suite modelled data assuming a hydroxyl reaction at 25°C
and a hydroxyl radical concentration of 1.5x106/cm³,
aliphatic acids are subject to photodegradation in air (SIDS, 2009). The
photodegradation half-lives in air decrease with increasing chain
lengths and range from 15.4 hours for octanoic acid (C8) to 5.7 hours
for octadecanoic acid (C18).
photolysis is not expected to contribute appreciably to the overall
breakdown rate in water and soil, since the environmental degradation of
these substances is predominantly of biotic nature.
