Abstract
A water-soluble home care concentrate is provide which includes a blend of zinc ricinoleate; and at least one alkoxylated amine having the formula R(nAO)sNHt, wherein R is a saturated or unsaturated, linear or branched alkyl containing from 8 to 22 carbon atoms; AO is a C2-C6 alkoxylate; n is the number of moles of AO and is from 1 to 50; s=1, 2 or 3; t=0, 1 or 2; and the sum of s and t is 3. The present invention also relates to diluted formulations that include the inventive water-soluble concentrate and at a least one solvent such as water and/or a carboxylic acid that is capable of solubilizes the concentrated blend into a diluted formulation that contains about 20%, by weight, or greater activated zinc atoms therein which are capable of binding with malodor molecules. The present invention also provides home care formulations that include the inventive diluted formulation and at least one additional formulating agent such as a perfume, dye, surfactant and the like. Methods of forming the inventive water-soluble concentrate, diluted formulation and home care formulations are also provided in the present invention.
