Control of female body odours

Abstract

The invention concerns the control of female body odours, particularly odours associated with body fluids, namely products of the genito-urinary tract, such as menstrual or catamenial fluids, vaginal fluids, urine, by use of low odour compositions of fragrance materials. The composition of fragrance material includes at least 5% of one or more musks and at least 5% of one or more salicylates.
