Abstract:
A process for preparing a liquid cleaning composition suitable for cleaning surface coatings, said process comprising the successive steps of:(a) forming a natural soap at an elevated temperature in an aqueous medium reaction of a fatty acid derivative with alkali;(b) adding in any sequence, an ester solvent and a nonionic surfactant; and(c) producing a stable dispersion of abrasive particles in the aqueous medium by adding abrasive particles at a controlled rate to the aqueous medium with agitation, wherein the ester solvent has a Hansen solubility parameter in the range of 9.5 to 11, and is present in an amount of 3.0% to 7.2% by weight based on the total weight of the composition, the surfactant and soap are present in a total amount of 3.5% to 7.5% by weight of active material based on the total weight of the composition, the amount of abrasive is from 0.5% to 4.0% by weight of the total composition, and the total amount of water is at least 70% by weight of the total composition.
