[The effect of bath additive concentration and the water temperature on the refatting effect of oil bath additives].
The refatting effects of three different oil bath products was tested in 30 healthy subjects. In each case the concentration of the therapeutic bath oils and the temperature of the bath water were varied. It could be demonstrated in 2 of the tested products that a threefold increase in the concentrations (as recommended by the companies) significantly enlarges the refatting effect. A further increase in the concentrations significantly reduces this effect. An increase in the temperature of the bath water from 32 degrees to 38 degrees C significantly lessened the refatting effects of all 3 products.
