Description of key information

Preliminary test (Tier 1) showed that the product CAPA 3050 can be considered stable at pH 4 and 7 (50 °C)
At pH 9, 50 °C, CAPA 3050 seemed to be completely hydrolysed within 5 days. Kinetic studies gave a half-life of about 16 h at the given conditions.
 

Key value for chemical safety assessment

Half-life for hydrolysis:
16 h
at the temperature of:
50 °C

Additional information

Preliminary test (Tier 1) showed that the product CAPA 3050 can be considered stable at pH 4 and 7 (50 °C)

At pH 9, 50 °C, CAPA 3050 seemed to be completely hydrolysed within 5 days. Kinetic studies gave a half-life of about 16 h at the given conditions.

 

It is also worth mentioning the fact that the higher molecular oligomers of CAPA 3050 is not soluble in water, which means that only the lower molecular oligomers are submitted to the hydrolysis conditions.
