Perfuming compositions and uses thereof

摘要

A perfuming composition capable of prolonging the release of a perfuming component into the surrounding environment when applied on a surface. This composition utilizes hydrophobic block copolymers 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 surface and a method for increasing the long-lastingness of a perfuming component using these compositions.

主权项

1. A perfuming composition comprising
a) at least one hydrophobic polymeric material which has a grafted structure, is water insoluble and is formed of:
i) at least one ethanol-compatible block selected from the group consisting of poly (propylene glycol), poly (1,2-butylene glycol) and poly (1,4-butylene glycol);ii) poly(dimethylsiloxane) as a core, wherein the at least one ethanol-compatible block is linked to the core and wherein the at least one hydrophobic polymeric material does not include a poly(ethylene glycol) block; b) greater than 50% by weight, relative to the total weight of the composition, of ethanol; c) water; and d) from between 5 and 30% by weight, relative to the total weight of the composition, of at least one perfuming component;
wherein the hydrophobic polymeric material is present in an amount sufficient to retard evaporation of the perfuming component and increase long lastingness of the perfuming component that is released from the composition.
