SOAP & DEODORANTSoap must have the required degree of plasticity within an operating temperature of 30-40°C.
It is particularly important to achieve the correct plasticity at the final pressing stage, since the compressed bar must be subject to a minimum of internal pressure to avoid serious cracking when the bar is used. To achieve the required degree of plasticity, certain factors must be controlled. For the dried soap base, these are: water content after drying; glycerol and electrolyte content; and the nature and quantity of any additives used in the liquid soap pre-drying.
