Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The available data from freshwater ecotoxicity studies on calcium myristate and calcium 12-hydroxystearate (Harlan 2013) showed no effects at up to 100 mg/L loading rate. In accordance with REACH Chapter R7b (ECHA 2012), PNECs have not been derived for freshwater, marine or intermittent release as the substances were tested as water accommodated fractions.

The substances have vapour pressures of less than 10 E-10 Pa, a low potential for bioaccumulation, are readily biodegradable, have a low potential for adsorption and are not applied directly to soil. Therefore, the STP, sediment, soil, secondary poisoning and air PNECs were not derived due to a lack of potential exposure or a lack of identified hazard.

Conclusion on classification

None of the substances in the calcium salts of monocarboxylic acids C14-C22 category showed acute toxicity to aquatic organisms at up to 100 mg/L WAF and therefore they do not meet the criteria for classification as acutely toxic to the aquatic environment under the DSD or the CLP.

Chronic aquatic toxicity data for calcium salts of monocarboxylic acids C14-C22 are only available for algae. These data would not result in a chronic classification under the 2ndATP to the CLP. All of the substances in the category are considered to be readily biodegradable, with a low potential for bioaccumulation. As the substances do not show acute toxicity at up to 100 mg/L, none of the substances in the calcium salts of monocarboxylic acids C14-C22 category meet the criteria for chronic toxicity to aquatic organisms.
