Witrynanaphthenate salts do not present unacceptable risks to human health or the environment when used according to label directions. As a condition of the continued … WitrynaA basic mechanism for the precipitation of naphthenate salts was presentedby Rousseau et al. This work indicated that the formation ofthe salts was a consequence of pH changes occurring during the fluid flow fromborehole to surface conditions. It was suggested this was due to CO2gas evolution. This, in turn, would lead to increases in …
WitrynaSodium naphthenate was not clastogenic in Chinese hamster ovary (CHO) cells, when tested with and without S9 (National Toxicology Program, 1993c). Calcium naphthenate showed a similar lack of clastogenic activity in a non-guideline study with rat liver RL4 cells when tested in the absence of S9 (Shell Research Ltd, 1983).
