Abstract
A device for stamping a detergent bar, i.e. a bar comprising soap, a synthetic detergent active or a mixture thereof, includes a die. The die has at least one bar stamping surface provided with at least one elastomeric coating which includes a conductive filler such as stainless steel powder. Good release of the detergent bars from the die is possible particularly when the dies are chilled. Use of the conductive filler facilitates chilling of the dies.
