NOTES

The skin was swabbed after 6h but measurements were made up until 24h. The vehicle was a commercial product which also contained 0.125% "proprietary ingredients" The % Absorption was given as +/- SEM. I have converted this to SD for this database. % Penetrated was calculated by adding the amount found in the receptor fluid to the amount found in the skin and stratum corneum.
