Aquatic bioaccumulation

The aquatic bioaccumulation potential of Coco fatty acids 2-sulfoethyl ester, sodium salt has been evaluated based on the partitioning behaviour of the test substance between octanol and water. The log Kow value of -0.41 for Coco fatty acids 2 -sulfoethyl ester, sodium salt is based on the ratio of the solubility in octanol and water.

For Lauric acid 2 -sulfoethyl ester, sodium salt which is the main component of Coco fatty acids 2 -sulfoethyl ester, sodium salt a low Log Kow of -2.02 was calculated using Kowwin (v1.67). One log Kow value of -1.56 which was measured according to EU guideline A8 is available for octanoic acid 2 -sulfoethyl ester sodium salt. The calculated Log Kow for this substance is -3.99 (Kowwin v1.67).

These results indicate that Coco fatty acids 2-sulfoethyl ester, sodium salt has a low bioaccumulation potential.

Terrestrial bioaccumulation

Data on terrestrial bioaccumulation is not required for the tonnage of 100-1000 tons per year. However, based on the weight of evidence presented under Section 4.3.1 of the CSR and considering the ready biodegradability of Coco fatty acids 2-sulfoethyl ester, sodium salt, it can be assumed that potential of Coco fatty acids 2-sulfoethyl ester, sodium salt for bioaccumulation in terrestrial organisms is low.
