[Methods and models for percutaneous absorption studies of organophosphates].

Organophosphates are highly toxic compounds, mainly penetrating the organism through the percutaneous route. In this context, having topical skin protectant capable of limitating their percutaneous penetration is of crucial importance for exposed people. Knowledge of the toxicokinetic parameters corresponding to the percutaneous penetration of these compounds is a key step for the development of these protective formulations. The different experimental approaches, in vivo and ex vivo, used to predict percutaneous penetration of these toxics are presented. The relevance and reliability of cutaneous experimental models are analysed.
