Abstract

The present invention relates to the field of perfumery. More particularly, it provides a perfuming composition capable of prolonging the release of a perfuming component into the surrounding environment when applied on a body surface such as skin or hair. The composition comprises Neopentyl Glycol Diethylhexanoate as a fragrance evaporation modulator in the presence of high amounts of ethanol. The invention also relates to consumer articles containing such compositions. It finally provides methods for the perfuming of a body surface and a method for increasing the long-lastingness of a perfuming component using these compositions.
