Experimental determination of a procedure for casting a solid coloured emulsion.
The aim of this study was to determine the experimental procedure for casting a solid water/oil (W/O) emulsion foundation. This process will enable us to preserve the organoleptic qualities of the foundation (hardness, surface appearance and cosmetic sensation) as well as maintaining the percentage of water contained in the formula. Two different industrial parameters were studied: * Influence of the temperature used to cast the bulk in the mould. * Influence of the type of cooling used for the mould, once full. For each trial, the hardness and the melting point were measured. The optimum results for this process were as follows: * Casting temperature: 65 degrees C. * Cooling temperature: 4 degrees C.
