A casting method of manufacturing a cosmetic product, which process comprises the following succession of steps: a) fluidization of at least one composition containing an oil, having a fluidization point between 30 ° C and 150 ° C, and an average hardness - measured at 25 ° C using a texturometer fitted with a hemispherical probe - between 0.5 N and 80 N, by heating it to a fluidization temperature above its fluidization point, b) introduction of the fluidized composition into a pouring nozzle, c1) casting by ejection of the fluidized composition through an orifice of the nozzle to obtain a volume, which volume is deposited on a support and, after cooling to 25 ° C, forms a first deposit of said composition on the support, c2) the relative setting in motion of the nozzle with respect to said support - in at least one of the three spatial directions - the pouring of the fluidized composition in step c1) and the relative setting in motion of the nozzle to step c2) being concomitant, so as to form a first deposit having a cylindrical shape, and the shape of the ejected volume being identical to the shape of the solid deposit, in the absence of mechanical or thermal stress applied to the deposit after casting, d) stopping the pouring, then possibly e) the relative displacement of the nozzle with respect to the support, and f) repeating steps a) to e) at least once to form at least one further deposit on said support, using the same composition or another composition which contains an oil, which has a fluidization point between 30 ° C and 150 ° C, and which has an average hardness - measured at 25 ° C using a texturometer fitted with a hemispherical probe - of between 0.5 N and 80 N. a) fluidization of at least one composition containing an oil, having a fluidization point between 30 ° C and 150 ° C, and an average hardness - measured at 25 ° C using a texturometer fitted with a hemispherical probe - between 0.5 N and 80 N, by heating it to a fluidization temperature above its fluidization point, b) introduction of the fluidized composition into a pouring nozzle, c1) casting by ejection of the fluidized composition through an orifice of the nozzle to obtain a volume, which volume is deposited on a support and, after cooling to 25 ° C, forms a first deposit of said composition on the support, c2) the relative setting in motion of the nozzle with respect to said support - in at least one of the three spatial directions - the pouring of the fluidized composition in step c1) and the relative setting in motion of the nozzle to step c2) being concomitant, so as to form a first deposit having a cylindrical shape, and the shape of the ejected volume being identical to the shape of the solid deposit, in the absence of mechanical or thermal stress applied to the deposit after casting, d) stopping the pouring, then possibly e) the relative displacement of the nozzle with respect to the support, and f) repeating steps a) to e) at least once to form at least one further deposit on said support, using the same composition or another composition which contains an oil, which has a fluidization point between 30 ° C and 150 ° C, and which has an average hardness - measured at 25 ° C using a texturometer fitted with a hemispherical probe - of between 0.5 N and 80 N.
