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 23.24 hours for hexanoic acid (C6) to 4.56 hours
for docosanoic acid (C22).
Direct 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.
