Key value for chemical safety assessment
Effects on fertility
Description of key information
No data are available on the reaction mass itself neither than on the two components.
However, once the reaction mass of calcium chloride and sodium chloride is taken up by the organism, the effect of the substance on animals and humans should be attributed to calcium ions, chloride ions and sodium ions. Since these three ions are essential constituents of the body, systemic toxicity is considered to be low and no reprotoxic effect is expected.
Furthermore, sodium chloride and calcium chloride are both present in food. Sodium chloride is an essential food additive; daily consumption for adults varies between 2 and 10 g. Calcium chloride was evaluated to be a food substance of very low toxicity and thus the establishment of the acceptable daily intake (ADI) for calcium chloride has not been deemed necessary by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). The substance has also been considered as generally recognized as safe (GRAS) substance by the U.S. Food and Drug Administration (USFDA). Systemic toxicity of both components is low and no reprotoxic effect is expected.

Effects on developmental toxicity
Description of key information
No data are available on the reaction mass itself.
Data are available on calcium chloride, one of the two components of the reaction mass. Three reports are available performed on rats, mice and rabbits by gavage. Based on these Three studies calcium chloride have no impact on the development.
Since the two components have no impact on reproduction, the reaction mass is expected not to induce effect on reproduction.
For the second component, sodium chloride, developmental toxicity studies were not performed on NaCl, as pregnant women typically consume several grams of salt per day (oral exposure) and potentially have dermal exposure to 2-3% NaCl in saltwater when bathing in the ocean. Due to the ubiquitous human exposures to NaCl without causally related developmental effects, animal testing is not necessary. Therefore developmental effect due to sodium chloride is not expected.
Since the two components have no impact on the development, the reaction mass is expected not to induce effect on the development.

Effect on developmental toxicity: via oral route
- Endpoint conclusion:
- no adverse effect observed
Justification for classification or non-classification
The two components of the reaction have no impact on reproduction and on development. Therefore, the reaction mass is expected to have no impact on reproduction and on development. No classification is required for these endpoints.
