WebTherefore, cyfluthrin is 42% active isomers when compared to beta-cyfluthrin (41/97 = 42). Therefore, the assumption is that the toxicity endpoints for beta-cyfluthrin should be 42% of the cyfluthrin endpoints (e.g., if the cyfluthrin endpoint is 1 mg a.i./L, than the estimated beta-cyfluthrin endpoint would be 0.42 mg a.i./L). WebBeta-cyfluthrin (a form of cyfluthrin) has been found to be twice as toxic as cyfluthrin if eaten or breathed in.3 Metabolites of cyfluthrin are less toxic than cyfluthrin itself.11 What happens to cyfluthrin when it enters the body Cyfluthrin is poorly absorbed through the skin.
