[0003] Ethanol constitutes a good solubilizing agent for perfuming ingredients, and additionally has the advantage of being inexpensive and of alloWing the formulation of trans parent compositions.

[0005] A ?rst route consists in replacing ethanol With aqueous compositions containing hydrophilic solubilizing agents such as polyethoxylated hydrogenated castor oils.

Moreover, the presence of Water in a large quantity is capable of causing degradation of the perfuming ingredients over time and therefore of adversely affecting the olfactory characteristics of the product.

[0006] Another solution further consisted in providing perfume compositions in Which the ethanol is at least partially replaced by one or more volatile silicones Which are lineariof the polydimethylsiloxane type4or cyclic.

[0007] HoWever, the applicant has noW discovered, sur prisingly, that by choosing a particular combination of silicone compounds not described in the prior art, it Was possible to obtain a perfume composition Whose rate of evaporation is close to that of ethanol and possessing a ?ash point greater than or equal to 00 C., preferably greater than or equal to 10° C. [0008] The subject of the present invention is therefore a perfume composition comprising a mixture of fragrant mate rials in a physiologically acceptable carrier comprising a mixture of polydimethylsiloxanes, characterized in that the said mixture of polydimethylsiloxanes consists of hexam ethyldisiloxane and octamethyltrisiloxane in a hexamethyl disiloxane to octamethyltrisiloxane Weight ratio ranging from 30:70 to 70:30.
