Administrative data

Endpoint:
hydrolysis
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 readily biodegradable

Data source

Materials and methods

Results and discussion

Total recovery of test substance (in %)
Remarks on result:
not measured/tested
Remarks:
The potential for the substance to undergo hydrolysis cannot be evaluated using simulation software such as the EPIWIN suite due to lack of hydrolysable functional groups. However, it contains an amide functional group that could potentially hydrolyze into a carboxylic acid and an amine. In general, amides are much less hydrolytically reactive than esters and hydrolysis half-lives can range from hundreds to thousands of years in the aquatic environment. Shelf-life determinations indicate that aqueous solutions of Sodium cocoyl apple amino acids [Na Cocoyl Apple AA] at pH 7 resist hydrolysis for months under normal storage conditions.

Applicant's summary and conclusion

Conclusions:
In accordance with column 2 of REACH Annex VIII, the hydrolysis test does not have to be conducted because the substance Sodium cocoyl apple amino acids [Na Cocoyl Apple AA] is readily biodegradable. It is shown that biodegradation is the primary route of degradation in the environment.
Executive summary:

In accordance with column 2 of REACH Annex VIII, the hydrolysis test does not have to be conducted becausethe substanceSodium cocoyl apple amino acids [Na Cocoyl Apple AA]is readily biodegradable. It is shown that biodegradation is the primary route of degradation in the environment.
