Abstract: Detergent compositions are disclosed which contain on a dry weight basis, from 1 to 40% of a water-insoluble aluminosilicate and from 0.5 to 5% of a aminopoly(methylenephosphonate) component which is a mixture of an ethylenediamine derivative of the formula ##STR1## and a diethylenetriamine derivative of the formula ##STR2## wherein, in each formula, R is selected from H, --CH.sub.2 PO.sub.3 M.sub.2 and --CH.sub.3 wherein M is selected from hydrogen and alkali metal, provided that at least 3 Rs are --CH.sub.2 PO.sub.3 M.sub.2 and further provided that the weight ratio of ethylenediamine derivative to diethylenetriamine derivative is from 3:1 to 1:5, and the combined weight of the aluminosilicate material and the aminopoly(methylenephosphonate) component is at least 5% of the dry weight of the composition.

Abstract: Improved detergent powder compositions containing at least a detergent-active material, a detergency builder and sodium perborate monohydrate, and method of making such compositions are disclosed, the improvement being that a sodium perborate monohydrate is used which has physical characteristics of specific surface area (SA in m.sup.2 /g) and pore volume (PV in cm.sup.3 /g) such that the formula (SA+31.25 PV-16.25) is greater than zero. The detergent powder compositions comprising said specific perborate monohydrate have less tendency to caking during storage under high humidity climatic conditions and have the further advantage of maintaining their quick bleach delivery in solution owing to said perborate monohydrate which retains its rapid rate of dissolution despite water-uptake during storage.

Abstract: A method of washing textile objects comprises pre-washing in a liquid composed of an organic dissolvent, preferably perchloroethylene, main washing in a liquid composed of a mixture of the organic dissolvent, a tenside and water, and at least two subsequent rinsing period, the objects being spin dried after each washing or rinsing period. The main-washing liquid is composed of a microemulsion whose water contents amount to between 4 and 30, preferably 10-30, percentage by weight and the first rinsing is made in a liquid composed of the organic dissolvent to which tenside has been added. A device for performing the method comprises three receptacles (11, 26, 32) for storing microemulsion, perchloroethylene, and used rinsing liquid from the first and preferably also from the second rinsing, respectively. The three receptacles communicate with a container (10) for the objects to be washed, which container can be supplied with tenside and water, respectively, from a dosing device (56).

Abstract: There is disclosed a composition of matter useful for stripping paint and varnish from substrates comprised of the conventional industrial chlorinated solvents, e.g. methylene chloride (dichloromethane) solvent and a wax, such as paraffin wax, which composition is improved by the addition thereto of a novel class of evaporation retarding chemicals resulting in a far more effective stripping action and a much improved environmentally desirable composition, with respect to the concentration of methylene chloride in the ambient atmosphere surrounding the work situs. The evaporation retarding chemical can be a surfactant, a resin plasticizer or ethylene or propylene carbonate.

Abstract: Water-soluble polymers comprising an N-vinyl lactam are found to be useful in processes wherein the polymer is introduced into a subterranean wellbore.Polymers useful in the recovery of natural resources are prepared by polymerizing an N-vinyl lactam by free radical initiation, with polymerization conducted in an aqueous solution polymerization medium preferably containing a mixture of dissolved electrolytes, or in a polymerization medium consisting essentially of a tertiary alkanol. Copolymers of such N-vinyl lactams with unsaturated amides, and terpolymers prepared by polymerizing an N-vinyl lactam and an unsaturated amide with a selected termonomer compound are also useful when prepared by these methods.

Abstract: The invention relates generally to products useful for home laundering, and more particularly to a product which incorporates a prespotter with a detergent and having one or more of the following separate functions: detergency, fabric softening, stain removal, bleaching, and bluing; with the advantage being that both the detergent and the prespotter are uniquely packaged together as one product, negating the need to purchase and store separate products for each end use function, and also, unavoidably providing presentation of the pre-spotter to the detergent user at the time of laundering. The invention also concerns methods of use of such products during laundering.
