  • Perfuming compositions and uses thereof
    Patent number: 9000052
    Abstract: 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.
