Perfume Compositions

Abstract

Perfume compositions comprise between 10% and 30% in total weight of perfume ingredients selected from two groups, Group A, Group B, with the provisos that over 5% but less than 15% of the perfume composition must comprise Group A ingredients, and for compositions comprising less than 10% of Group A ingredients in the aggregate percentage of Group B ingredients present must be at least equal to the expression (2*/10−A %) where A % is the total percentage of Group A ingredients in the composition.
