Additional information

Cassia oil is a Natural Complex Substance, a mixture consisting of a range of constituents with varying solubility. Therefore the tests on aquatic organisms were performed with Water Accomodated Fractions in order to provide data for classification. The volume is 1-10 tonnes/year, therefore no PNEC is derived and no Hazard assessment or PBT assessment is conducted.

Conclusion on classification

Cassia is a Natural Complex Substance, a mixture consisting of a range of constituents with varying solubility. It was shown to be readily biodegradable. Log Kow ranges from 1.51 to 2.89 and for 77% of the NCS, log Kow is 1.82. Thus there is no potential for bioaccumulation.

The EL50 of this NCS for algae and Daphnia was experimentally established to be 3.3 and 3.8 mg/L (WAF). Thus, the lowest ecotoxicity value, the 72h-ErL50 with Algae, is between 1 and 10 mg/L. As the substance is readily biodegradable and log Kow < 4, it is concluded that Cassia oil does not classify for aquatic hazards according to Regulation 1272/2008/EC (CLP).
