OIL ADSORPTION - A METHOD FOR DETERMINING THE AFFINITY OF SKIN TO ADSORB OIL FROM AQUEOUS DISPERSIONS OF WATER-DISPENSABLE OIL PREPARATIONS

[摘要] A method for determining comparative adsorption of oils by the skin from water-bath oil dispersions is described. Comparison between right arm and left arm adsorption is possible only when made simultaneously, since day to day variations are appreciable. Periods of soaking longer than 20 minutes do not appear to cause significant increase in oil adsorption. Adsorption apparently increases as temperature of the bath is raised. Adsorption is greater when the concentration of oil is increased. Mineral oil type bath oils are adsorbed better than vegetable oil type bath oils. Adsorption of oatmeal-oil type bath oils is very poor, probably because of affinity of finely pulverized oatmeal for the oils incorporated in it. The clinical significance of these differences in cutaneous oil adsorption has not been established.
