Abstract
This invention relates to a general purpose household cleaner or cleaning composition in granular, powdered aggregated, agglomerated, pasty or liquid form, to be diluted in water, but which can be applied as such when in liquid form, effectively removing both organic- and inorganic-, acidic- and alkaline soil without requiring any additional rinsing step or steps and/or wiping, containing a specific organic, anionic surface-active detergent and a lower polypeptide having a molecular weight below 600, and an isoelectric point of at least 5.5, or mixtures of said polypeptides, or a protein hydrolysate containing mainly lower polypeptides, having an isoelectric point of at least 5.5, and a neutral carrier. More particularly, it relates to a general purpose household cleaning composition, preferably to an aqueous, liquid, homogeneous, clear, general purpose household cleaning composition for hard surfaces, substantially free of inorganic and/or organic builder salts, to be diluted in hard water, containing a specific organic, anionic, surface-active, detersive sulfuric acid reaction product, a lower polypeptide having a molecular weight below 600, preferably between 350 and 450, and an isoelectric point above 5.5 and mixtures thereof, or a protein hydrolysate consisting of at least 50% by weight of lower polypeptides having a molecular weight below 600, preferably between 350 and 450, and an isoelectric point of at least 5.5, and containing at most 15% by weight of organic amino acids and at most 25% by weight of penta- and higher polypeptides, and a neutral carrier, preferably water.
