Abstract
The present invention relates to a method of making a solid cleaning composition. The method can include pressing and/or vibrating flowable waxy particles of a waxy cleaning composition. For a waxy cleaning composition, pressing and/or vibrating flowable waxy particles 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.
Claims23
A method of making a stable solid cleaning composition comprising:
- providing flowable waxy particles comprising about 40 to about 75 wt % of a solidification agent selected from the group consisting of a polyethylene glycol, an anionic surfactant, urea, and mixtures thereof;
- and an ingredient selected from the group consisting of alkalinity source, acidulant, stabilized microbial or enzyme composition, surfactant, sequestrant, and mixtures thereof;
- putting the flowable waxy particles in a drawer;
- vibrating the flowable waxy particles in the drawer;
- transferring the flowable waxy particles from the drawer into a form;
- gently pressing the flowable waxy particles in the form at ambient temperature, with a force of about 1 to about 1000 psi to produce the stable solid cleaning composition, vibrating the flowable waxy particles in the form to produce the stable solid cleaning composition, or combination thereof;
- and
- removing the solid cleaning composition from the form, wherein the solid composition is a block having a mass of about 1 to about 10 kg and the method does not employ extruding the flowable waxy particles, or a melt and a solidification of the flowable waxy particles to form the solid block.
