Estimating the term…
A process for forming detergent bars by injection molding in which a pressure is applied to a partially structured detergent composition to deliver it to a mold. The detergent composition can be delivered to the mold in a substantially semi-solid state, at a temperature below 70° C. and at a pressure at the point of injection of greater than 20 psi. Apparatus for forming detergent bars according the invention are also described.
A process for forming detergent bars comprising applying pressure to a detergent composition to deliver the detergent composition to a mould characterised in that the detergent composition is at least partially structured when it enters the mould.
An apparatus for forming detergent bars comprising a means for applying pressure to a detergent composition to deliver the detergent composition to a mould and a substantially separate means adapted for feeding detergent composition to the means for applying pressure.
An apparatus for forming detergent bars comprising
A method for incorporating an additive or benefit agent into a detergent bar, comprising adding the additive or benefit agent to a detergent composition which is at least partially structured and applying a pressure to the detergent composition containing the additive or benefit agent so as to deliver it to a mould.
A process for forming detergent bars comprising applying pressure to a detergent composition to deliver the detergent composition to a mould characterised in that the pressure at the point of entering the mould is greater than 20 psi for at least part of the time over which the detergent composition is entering the mould.
A process for forming detergent bars comprising applying pressure to the detergent composition to deliver the detergent composition to a mould characterised in that the detergent composition is at a temperature below 70° C. when entering the mould.
