1. A casting process for the manufacture of a cosmetic product comprising:

  • a) heating a solid composition containing an oil and having a fluidification point ranging from 30 to 150°

    C. and a mean hardness, as measured at 25°

    C. using a texture analyzer provided with a hemispherical probe, ranging from 0.5 to 80 N, to a temperature greater than said fluidification point so as to obtain a fluid composition;

    b) introducing the fluid composition into a casting nozzle having an orifice with a diameter ranging from 0.01 to 5 mm;

    c1) casting the fluid composition through the orifice at a casting temperature and at a casting flow rate ranging from 0.05 to 2 mm3/s, obtaining an ejected volume of fluid composition, dropping said ejected volume to a support thereby cooling said ejected volume to 25°

    C. and forming a solid deposit of the composition on said support, the solid deposit essentially retaining the form of the ejected volume at the orifice;

    c2) changing the nozzle position with respect to the support and moving the nozzle in at least one of the three space directions;

    d) halting the casting of the fluid composition, then optionallye) changing the nozzle position with respect to the support, andf) repeating a) to e) above at least one time with said composition or with another composition, wherein the other composition contains an oil, has a fluidification point ranging from 30 to 150°

    C., and has a mean hardness, measured at 25°

    C. using a texture analyzer provided with a hemispherical probe, ranging from 0.5 to 80 N, andwherein the support does not act as a container for the volume of the fluid composition, andthe solid deposit has essentially the form of a sphere having a diameter ranging from 0.01 to 1 mm.
