Perfuming composition

Abstract

The present invention relates to a perfuming eau de toilette or eau de parfum composition comprising a high proportion of alcohol, for direct application on the skin or hair by spraying. More specifically, it relates to a sprayable perfume composition having excellent properties such as persistence of the olfactory note once applied on the skin. The composition is transparent and contains ethanol, 0 to 30% by weight of water, 3 to 40% by weight of a perfume concentrate and a copolymer of vinylpyrrolidone and vinyl acetate.

1 . A perfuming composition comprising:
 from 40% to 90% by weight of ethanol,   from 0% to 30% by weight of water,   from 3% to 40% by weight of a perfume concentrate, and   from 1% to 10% by weight of a vinylpyrrolidone/vinyl acetate copolymer,   
       the percentages being expressed relative to the weight of the composition. 
     
     
         2 . The composition as claimed in  claim 1 , characterized in that the perfume concentrate represents from 10% to 35% by weight, and the copolymer represents from 2% to 5% by weight of the weight of the composition. 
     
     
         3 . The composition as claimed in  claim 1 , characterized in that the copolymer extends the perception of the perfume over time, in particular the top notes and the heart notes of the perfume, for a user who has sprayed the composition onto their skin or their clothing, this increase being evaluated relative to the same composition not containing said copolymer. 
     
     
         4 . The composition as claimed in  claim 1 , characterized in that the copolymer is solid at 25° C., in that the weight ratio of the vinylpyrrolidone to the vinyl acetate in the copolymer ranges from 50:50 to 70:30, and in that the weight-average molecular weight of the copolymer is between 15 000 and 600 000. 
     
     
         5 . The composition as claimed in  claim 1 , characterized in that the weight ratio of ethanol to water is between 65/35 and 98/2. 
     
     
         6 . The composition as claimed in  claim 1 , characterized in that the composition contains from 15% to 25% by weight of perfume concentrate, from 55% to 65% by weight of ethanol and from 15% to 25% by weight of water relative to the weight of the composition. 
     
     
         7 . The composition as claimed in  claim 1 , characterized in that the composition contains from 25% to 35% of perfume concentrate, from 70% to 80% by weight of ethanol and 0% by weight of water relative to the weight of the composition. 
     
     
         8 . The composition as claimed in  claim 1 , characterized in that the composition contains from 15% to 25% by weight of perfume concentrate, from 75% to 85% by weight of ethanol and from 0% to 5% by weight of water relative to the weight of the composition. 
     
     
         9 . A bottle comprising a spraying means and a packaging means, and containing a perfuming composition as claimed in  claim 1 . 
     
     
         10 . The bottle as claimed in  claim 1 , characterized in that the composition is transparent. 
     
     
         11 . The bottle as claimed in  claim 9 , characterized in that the composition is a solution in the form of eau de toilette, eau de cologne, perfume extract, esprit de parfum or eau de parfum. 
     
     
         12 . The bottle as claimed in  claim 9 , characterized in that the spraying means is a manual pump. 
     
     
         13 . The use of a vinylpyrrolidone/vinyl acetate copolymer in a perfuming composition, for extending the period of time during which the olfactory note of said composition is perceived by the sense of smell of a user having applied it to a support, this increase being evaluated relative to the same composition not containing said copolymer. 
     
     
         14 . The use as claimed in  claim 13 , characterized in that the composition is a perfuming solution in the form of eau de toilette, eau de cologne, perfume extract, esprit de parfum or eau de parfum, applied to the skin, the hair or the clothing. 
     
     
         15 . The use as claimed in  claim 14 , characterized in that the copolymer extends the perception of the top notes and of the heart notes of the olfactory note. 
     
     
         16 . A diffuser comprising a support impregnated with a perfuming composition as claimed in  claim 1 . 
     
     
         17 . The diffuser as claimed in  claim 16 , characterized in that the support is a porous support, for example a fabric or a ceramic. 
     
     
         18 . The diffuser as claimed in  claim 16 , characterized in that it is obtained by impregnating the perfuming composition i) by capillary action, after the composition has been either poured dropwise, or sprayed onto the support, or ii) by dipping the support in a container containing the perfuming composition.
