A soap bar composition comprising solid soap and an oil-in-water emulsion, wherein the emulsion comprises one or more surfactants and wherein the emulsion is dispersed within the solid soap.

The present invention relates to a method of making a solid cleaning composition. The method can include pressing and/or vibrating a flowable solid of a self-solidifying cleaning composition. For a self-solidifying cleaning composition, pressing and/or vibrating a flowable solid determines the shape and density of the solid but is not required for forming a solid. The method can employ a concrete block machine for pressing and/or vibrating. The present invention also relates to a solid cleaning composition made by the method and to solid cleaning compositions including particles bound together by a binding agent.

A method of adjusting dispense rate of a solid detergent block of a detergent composition is described here. A solid detergent block is produced from this method may have a predetermined dispense rate or a comparable dispense rate as a solid detergent block produced by extruding method. A process for producing a solid detergent block and a solid detergent composition are also disclosed.

The present disclosure is related to apparatuses, processes, and extrusion screws directed to process solid detergent compositions in shapes like billets, bars, tablets, noodles, and similar shapes produced from extruded synthetic detergents, soaps, and combinations thereof. The present disclosure describes an extrusion screw for processing synthetic detergents, soaps, and combinations thereof. The extrusion screw comprises a feed section, a metering section, and a compression section. Said compression section has a proximal channel depth adjacent to the feed section, and a distal channel depth adjacent to the metering section, and a compression ratio that may be between 2.2, and 4.1, for example, between 2.2, and 2.6. The extrusion screw may have a length to diameter ratio (L/D) that may be between 4.0, and 6.0. The present disclosure also describes an apparatus for processing synthetic detergents, soaps, and combinations thereof. The apparatus comprises a barrel and said extrusion screw. The present disclosure also describes a process for extruding solid synthetic detergents, soaps, and combinations thereof. The process comprises a step of providing a formulation that may be selected from synthetic detergent, and half-synthetic soap to said apparatus, and compressing said formulation at a temperature between 32° C., and 42° C. with a compression section of the extrusion screw. The screw rotation speed of the extrusion screw may be between 4, and 20 RPM. The formulation may be provided prewarmed. The screw rotation speed of the extrusion screw may be between 4, and 35 RPM (e.g., between 4 and 20 RPM).

The present invention relates to an extruded soap bar composition. It more particularly relates to a soap bar composition which comprises low amount of soap where high amount of water can be incorporated. This is achieved by including selective amount of a mixture of sodium or calcium silicate and an acrylic/acrylate polymer, wherein the soap bar comprises 0.01 to 0.7 wt % of the polymer. The soap bars of the invention are easy to extrude and has acceptable product hardness.
