Abstract
The anti-gel and dispersibility properties of a nonaqueous liquid nonionic surfactant laundry detergent composition are improved by the addition of hexylene glycol to the composition. The addition of hexylene glycol reduces the plastic viscosity of the composition with little or no adverse affect on yield stress value of the composition or adverse affect on the physical stability of the composition. The addition of hexylene glycol and propylene carbonate to the nonionic surfactant composition substantially reduces the apparent viscosity of the composition and substantially improves the dispersibility of the composition.
