SUMMARY Skin samples from hairless mice were treated with reagents and the diffusion of water was determined to obtain information about the chemical nature of the epidermal water barrier. The flux of tritiated water was determined in diffusion chambers and changes in barrier function were evaluated by calculation of the ratio of the diffusion rates obtained prior to and alter application of the reagent. After application of chloroform ethylether acetone and DM
