Fully diluted hard surface cleaners are disclosed which are particularly effective on cleaning soap scum. The cleaners contain at least 0.45 eq/kg of a dissolved anion which reacts with calcium ion to form an insoluble salt. The cleaners also contain a particular amine oxide, or a different surfactant in conjunction with a solvent. Preferred embodiments include a bleach, which provide for a cleaner which is effective on soap scum and mold and mildew.

Fully diluted hard surface cleaners containing high concentrations of certain anions

The invention concerns certain insecticidal compositions of ingestible insecticides selected from the group consisting of DNA viruses, RNA viruses and bacteria of the order Bacillus such as, for example, Bacillus thuringiensis var. israelensis entrapped by a suitable charged polymer. The invention also concerns a process for the preparation of and the use of such insecticidal compositions.

Insecticidal compositions and process for preparation thereof

Lipase activity is determined in an improved process for determining the activity thereof by providing a triglyceride imbibed or absorbed in a triglyceride swellable triglyceride insoluble polymer having a predetermined particle size.

Process for the determination of lipase activity

A method for controlling acne or acneform eruptions in humans is disclosed. The method involves the topical application of one or more sebum-imbibing, sebum-retaining polymers either alone or in combination with a pharmaceutically acceptable carrier.

Acne control method

Nonblocking oil-swellable oil-insoluble synthetic resinous particle are prepared using isobornyl methacrylate as major monomer.

Oil imbibing polymer particles which are block resistant

Contact dermatitis caused by exposure of the skin to the allergen present in plants of the genus Rhus, is treated and controlled by topical application of an effective amount of an allergen-imbibing, allergen-retaining polymer or a pharmaceutically-acceptable composition containing such polymer.

Method for treating contact dermatitis

Pharmacologically-acceptable fat imbibing polymers are introduced into the gastrointestinal tract of animals to control body weight.

Weight control with fat imbibing polymers

Magnetic imbiber polymers are prepared by grafting a water soluble polymer on the surface of an oil imbiber polymer and exposing the grafting imbiber polymer to a colloidal magnetic material such as magnetic iron oxide.

Magnetic imbiber polymers and method for the preparation thereof

Water containing traces of oil is cleaned by passing the oil containing water through a foraminous body, the foraminous body having a coating on the surface thereof of an oil-imbibing, oil-swellable latex polymer in a quantity sufficient to blind the foraminous body when the latex is oil swollen.

Separation of oil from water

Unstabilized vinylbenzyl chloride and substituted vinylbenzyl chlorides are essentially inert with respect to surfaces of aluminum or alloys containing at least 90 percent by weight of aluminum in sharp contrast to benzyl chloride and similar substituted benzyl halides. Aluminum and such alloys of aluminum are thus practical materials of construction for making containers, pipes, stills, still column packing and the like for handling vinylbenzyl chloride.

Aluminum container for processing vinylbenzyl chlorides

Ar-halo-ar(t-alkyl)styrenes, e.g., 2-chloro-4-(t-butyl)styrene, polymerize to form materials having unusually high temperature resistance. Additionally, compositions of such monomers, unsaturated polyesters and free-radical generating catalysts cure at lower temperatures and in less time than similar compositions containing conventional styrene monomers.

Ar-halo-ar(t-alkyl)styrenes and polymers thereof

Water containing traces of oil is cleaned by passing through a porous bed containing oleophilic bodies and oil imbibing bodies. Oil is collected on the surface of the oleophilic bodies and removed from the oleophilic bodies by the oil imbibing bodies. Such beds have a high capacity for oil retention while maintaining separating efficiency.

Ar-halo-ar(t-alkyl)styrenes polymers

A valve is disposed in a line carrying an aqueous stream, the valve in the form of a permeable bed of particulate swellable polymer particles which imbibe organic materials and on contact therewith will swell to provide a positive shut-off and a polymeric structure which collapses on contact with organic liquid is disposed upstream of the permeable bed. Flow rates can be obtained which are higher than the flow rates with polymer particles alone.
