  • such sticks are tried to incorporate skin-softening or refatting components. This leads to inhomogeneity and separation in the known water-insoluble oil components. Therefore, water-soluble or water-dispersible emollients have always been used, e.g. according to EP-A 450 597 the alkylene oxide adducts with fatty alcohols. However, these products do not have sufficient cosmetic and skin-care effects.
  • EP-A 499 304 therefore proposed the use of very specific fragrances. It has now been found a way to incorporate water-insoluble oils in substantial quantities in a stable and homogeneous manner in soap gel preparations.
