Abstract
A detergent bar is made by (1) applying pressure to a detergent composition to deliver it to a substantially closed mold at a temperature less than 70° C.; (2) ensuring the pressure on the composition at point of entry is greater than 29.4 psi under the action of an injector head for at least part of the time over which the composition enters the mold; (3) cooling in the mold to form bar; and (4) removing.
