Saponification and oxidation product of carnauba wax with acidic sodium dichromate solution esterified with 1-methyl-1,3-propanediol and subsequent saponification with calcium dihydroxide

Ecotoxicological Summary

Additional information

Members of the category of carnauba waxes were tested in concentrations far above their water solubility. No effects were observed in any of the tests:

Short-term toxicity fish (montan waxes, type E): EC50 > 10000 mg/l

Short-term toxicity daphnia (carnauba waxes, type OP): EC50 > 100 mg/l

Short-term toxicity daphnia (montan waxes, type E): EC50 > 10000 mg/l

Algae toxicity (carnauba waxes, type OP): EC50 > 100 mg/l

Algae toxicity (montan waxes, type S and OP): EC50 (72 h) > 100 mg/l, (type E): EC50 (72h) > 320 mg/l

Activated sludge respiration inhibition (montan waxes, type S, E and OP): EC50 > 10000 mg/l

Long-term reproduction daphnia (montan waxes, type S): NOAEC = 100 mg/l

Short-term toxicity earthworm (montan waxes, type OP): NOAEC (14d, mortality, behaviour, body weight) = 1000 mg/kg soil dw

Reproduction test earthworm (montan waxes, type OP): NOAEC = 1000 mg/kg soil dw

Consequently, no reliable LOEC, NOEC, or ECx - value can be calculated. Since this data is a prerequisite to estimate a PNEC it is not possible to derive such values.

Conclusion on classification

No toxicity to aquatic or soil organisms was detected in any of the available studies for the members of the carnauba wax category. Hence, no environmental classification is required for any of the category members.
