Reference
Endpoint:
hydrolysis
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Justification for type of information:
REPORTING FORMAT FOR THE ANALOGUE APPROACH
Refer to attached document
Reason / purpose for cross-reference:
read-across source
Transformation products:
no
Key result
pH:
7
Temp.:
25 °C
DT50:
> 1 yr
Remarks on result:
hydrolytically stable based on preliminary test
Key result
pH:
9
Temp.:
25 °C
DT50:
> 1 yr
Remarks on result:
hydrolytically stable based on preliminary test
Details on results:
The detected amounts of the Mono-and Diester after incubation at 50 °C for 5 days at pH 4, 7 and 9 are always > 90% (except Monoester at pH 4 with a detected amount of 85.6%, but this is in the range of uncertainness), i.e. according 0ECD 111 the test substance is hydrolytically stable; no hydrolysis does occur.
Conclusions:
Phosphoric acid, C12-18 alkyl esters, potassium salts is considered hydrolytically stable based on read-across information from Phosphoric acid, dodecyl ester, potassium salt.
