Estimating the term…
In an apparatus and process for manufacturing a detergent bar, the bar comprises a first distinct zone comprising a first component and at least a second distinct zone comprising a second component. In an injection step, the first and second components are injected into the mold cavity via nozzle means having a first orifice through which the first component is injected. The second component is injected through a second orifice of the nozzle means. The first and second components solidify in the cavity to form the bar. The interface between the zones may be non-planar and/or such that the zones cannot be separated by a unidirectional cut. The first and second zones may respectively comprise detergent and a benefit agent. The first and second zones may differ in texture.
A process for manufacturing a detergent bar comprising a first distinct zone comprising a first component and at least a second distinct zone comprising a second component, said process comprising an injection molding step in which said first and second components are injected into a mould via nozzle means having a first orifice through which said first component is injected and at least a second orifice through which the second component is injected, and a solidification step in which the first and second components solidify in the mould to form the said detergent bar.
