Described herein is a water-based, alkaline cleaner concentrate for producing a cleaner for metallic surfaces, the concentrate including a) at least one (meth)acrylic acid homopolymer having a weight-average molar mass in the range from 3 000 to 19 000 g/mol and b) at least one (meth)acrylic acid copolymer having a weight-average molar mass in the range from 50 000 to 100 000 g/mol. Also described herein are a corresponding cleaner for metallic surfaces with reduced pickling erosion, a process for anticorrosive treatment of metallic surfaces that includes a corresponding cleaning step, a metallic surface obtained by the process, and a method of use thereof in the sector of the metalworking industries.

The present invention relates to a polymer obtained at least from a quantity A of 2-acrylamido-2-methylpropane sulfonic acid, in acid and/or salified form, characterized in that the quantity A of 2-acrylamido-2-methylpropane sulfonic acid contains 250 to 20,000 ppm by weight of 2-methyl-2-propenyl-sulfonic acid, in acid and/or salified form. The present invention also relates to the use of this polymer as a flocculant, viscosity reducing agent, thickener, absorbent, friction reducing agent or plasticizer or superplasticizer, in particular in a field chosen from among oil and gas recovery, water treatment, sludge treatment, paper manufacture, construction, mining, cosmetic product formulation, detergent formulation, textile manufacture and agriculture.

A liquid laundry additive is provided, comprising a cleaning booster polymer having structural units of a monoethylenically unsaturated carboxylic acid monomer; structural units of an ethylenically unsaturated monomer of formula (I) ##STR00001##
optionally, structural units of an ethylenically unsaturated monomer of formula (III) ##STR00002##
and optionally, structural units of an ethylenically unsaturated monomer of formula (IV) ##STR00003##

A cleaning solution composition and a cleaning method using the cleaning solution composition are provided. The cleaning solution composition includes a chelating agent including a first organic acid and a second organic acid, and an etching agent including a fluoride compound.

A cleaning solution composition and a cleaning method using the cleaning solution composition are provided. The cleaning solution composition includes a chelating agent including a first organic acid and a second organic acid, and an etching agent including a fluoride compound.

The present invention relates to a method of making a solid cleaning composition. The method can include pressing and/or vibrating a flowable solid of a self-solidifying cleaning composition. For a self-solidifying cleaning composition, pressing and/or vibrating a flowable solid determines the shape and density of the solid but is not required for forming a solid. The method can employ a concrete block machine for pressing and/or vibrating. The present invention also relates to a solid cleaning composition made by the method and to solid cleaning compositions including particles bound together by a binding agent.

The disclosed technology relates to pure polyitaconic acid homo- and co-polymers free of the less reactive tri-substituted vinyl monomers (e.g., citraconic acid or mesaconic acid) that may be used, for example, as builders in detergent applications, such as in the personal and home care market.
