Key value for chemical safety assessment

Additional information

No studies of toxicity to birds are available for HMDTMP (4-7Na). A 10-day LD50 value of >2510 mg/kg based on test material, equivalent to >610 mg active acid/kg, has been reported for the effects of the analogous potassium salt, HMDTMP (4-7K) on mortality of bobwhite quail, Colinus virginianus, and mallard duck, Anas platyrhynchos. No effects on feed consumption and body weight were recored. Neither studies have been selected as key since short-term toxicity studies are not sufficient to fulfil this endpoint.

Testing is not considered necessary because the log Kow of the registered substances are very low (<<3) and, therefore, bioaccumulation is not of concern for these substances.
