Abstract
The invention concerns emulsions based on non-ionic emulsifiers, with improved stability achieved by the addition of selected perfumery materials, and a process for preparing such emulsions. The emulsions comprise 1-30% by weight of one or more non-ionic emulsifiers 30-98% of an aqueous phase and 0.01-50% of hydrophobic materials. The stabilizing perfumery materials are present in 0.5-25% by weight based on the non-ionic emulsifiers. The emulsions are preferably prepared under low shear.
