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 surface. The composition comprises 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.
