Enhanced dispensing of solid compositions
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.
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.
