Abstract

A solid detergent composition includes an ethoxylated and propoxylated surfactant, an alkalinity source, a solidification agent and a chelating agent. The ethoxylated and propoxylated surfactant can include a surfactant blend of naturally sourced ethoxylated and propoxylated surfactants.

Claims (16)

1. A solid detergent composition comprising:

(a) between about 1% and about 60% by weight of an ethoxylated and propoxylated surfactant which comprises a palm kernel based ethoxylate and propoxylate surfactant;

(b) between about 1% and about 50% by weight of an alkalinity source;

(c) between about 1% and about 12% by weight of a solidification agent;

(d) between about 1% and about 60% by weight of a chelating agent; and

wherein the solid detergent composition is a cast solid detergent composition and the composition is substantially free of phosphorous-containing compounds and alkyl phenol ethoxylates; and wherein the solid detergent composition exhibits a dispensing rate of at least 40 g/min.

2. The solid detergent composition of claim 1 , wherein the ethoxylated and propoxylated surfactant includes between 8 and 18 carbon chains.

3. The solid detergent composition of claim 1 , wherein the ethoxylated and propoxylated surfactant has an equilibrium surface tension, as measured at 0.1 wt % and 25° C., of between about 20 dynes/cm and about 40 dynes/cm.

4. A solid detergent composition consisting of:

(a) a palm kernel based surfactant including ethoxylate and propoxylate groups;

(b) an alkalinity source;

(c) a solidification agent;

(d) a chelating agent; and

optionally: anti-redeposition agent; optical brightener; thickener/viscosity modifier; dyes and/or fragrances; and wherein the solid detergent composition exhibits a dispensing rate of at least 40 g/min.

5. The solid detergent composition of claim 4 , wherein the palm kernel based surfactant constitutes between about 1% and about 60% by weight of the solid detergent composition.

6. The solid detergent composition of claim 4 , wherein the palm kernel based surfactant has an equilibrium surface tension, as measured at 0.1 wt % and 25° C., of between about 20 dynes/cm and about 40 dynes/cm.
