Abstract: A cleaning solution for paper making equipment includes a stabilized source of peroxide in combination with a glycol ether solvent system and an alcohol ethoxylate. The peroxide system can be hydrogen peroxide stabilized with a phosphonate such as HEDP. The glycol solvent system may be a propylene glycol ether such as dipropylene glycol methylether or tripropylene glycol methylether. This solution can be formulated with a pH from about 4 to about 12. This is used by recirculating it through a paper making equipment during a shut down procedure.

Abstract: The invention concerns a cleaning composition comprising an aqueous solution containing between 0.05 to 5 wt. % of sodium metaperiodate and between 0.05 and 0.75 wt. % of sulfuric acid, and an aqueous solution of 0.5 to 90 wt. % of a mixture of dialkylesters and of 0.5 to 50 wt. % of a non-ionic surfactant. The method for cleaning a silk screen consists in exposing it to such a composition to eliminate ink, the masking product and the ghost image. The device for cleaning comprises a first section (4) wherein are a first ramp (26) of nozzles for spraying a cleaning composition on the screen (2) and a second ramp (32) of nozzles for spraying water under high pressure, and with which is associated a drain tank (20) for recovering the cleaning product and a reservoir (14) of cleaning product separate from the drain tank (20).

Abstract: A water-based formulation for the removal of ink comprising a detergent builder including sodium carbonate, neutralized polyacrylic acid, and an acrylic acid/maleic anhydride copolymer; a chelating agent including tetrasodium ethylenediaminetetraacetate and ethylenediaminetetraacetic acid; and a detergent/emulsifier including C9-11 Pareth 8, C6-12 Pareth 6, and PEG Cocomonium Chloride.

Abstract: A cleaning medium for use in cleaning printing forms includes either an acid solution having a pH of from 1 to 4 or a basic solution having a pH of from 10 to 14. A dispersible abrasive agent in a concentration of from 1 to 15 grams per 100 grams of the cleaning composition, a surfactant in a concentration of from 1 to 50 grams per 100 grams of the cleaning composition, an organic solvent in a concentration of from 10 to 50 grams per 100 grams of the cleaning composition, and additional water if needed are added to the acid or basic solution to form the cleaning medium. A cleaning medium in concentrate form is also provided.

Abstract: The invention concerns a liquid de-inking composition comprising at least a surfactant of polyalkoxylated terpenic origin of formula: Z—X—W—[CH—(R5)CH(R6)-O]q—A wherein: Z is a bicycloheptenyl or bicycloheptyl radical, preferably substituted by methyl radicals; X is preferably a —CH2—CH2—O— or —O—CH2—CH2—O— radical; W is a polysequence, preferably polyoxypropylene and polyoxyethylne sequence; [CH(R5)—CH(R6)—O]q is a sequence different from a polyoxyethylene, preferably polyoxypropylene sequence; A is a hydrogen atom, a hydrocarbon or functional group. Said composition can be used for de-inking paper.

Abstract: A process for removing printing inks and/or oil residues located on a surface of a printing apparatus comprising: (a) contacting the printing inks and/or oil residues located on the surface of the printing apparatus with a cleaning composition containing an alkyl polyglycoside corresponding to formula (I): R(G)x  (I)  wherein R is a linear saturated alkyl radical having from 8 to 22 carbon atoms, and (G)x is a glycoside or oligoglycoside radical having a degree of oligomerization, x, of from 1 to 10 to form a printing ink and/or oil residue emulsion; and (b) removing the printing inks and/or oil residue emulsion from the surface of the printing apparatus.

Abstract: A composition and process for cleaning inks and organic residues from various substrates utilizing dimethyl piperidone and other safe solvents is revealed. The composition and process are particularly useful in cleaning printing plates and printing apparatus.

Abstract: A bleach and oxidation catalyst is provided comprising a catalytically active metal-complex having a poly-dentate ligand containing at least 6 hetero-atoms. Such metal-complexes can activate hydrogen peroxide, peroxy acids or molecular oxygen and were found to have both favourable stain removal and remarkable dye transfer inhibition properties. In addition, these complexes can be easily prepared.

Abstract: A "stickie" remover cleaning composition consists of aliphatic petroleum distillate, d-limonene, and an aliphatic dibasic acid ester mixture containing approximately 59% dimethyl glutarate, 21% dimethyl adipate, and 20% dimethyl succinate for use in paper mill production. "Stickies" are resinous type organic materials predominately commonly found in de-inked secondary fiber. Secondary fiber is pulp derived from telephone books, computer paper, etc., and are more common in de-inked secondary fiber than in virgin pulp.

Abstract: A low-toxicity solvent composition having broad-spectrum applicability. A polar solvent component is provided by an alicyclic carbonate and a non-polar solvent component is provided by a terpene, with a short-chained non-ionic surfactant being provided for coupling the alicyclic carbonate and terpene in a homogeneous, single-phase solution. The composition may be 25-60% propylene carbonate, 1% (or less)-20% d-limonene, and 40-60% tripropylene glycol methyl ether. This solvent composition is non-toxic to personnel, and presents minimal environment hazards. Among its many applications are paint equipment clean-up, cleaning and reclamation of silkscreens, cleaning of offset printing rollers, cleaning of aluma-printing surfaces and equipment, as well as general purpose clean-up of greases, oils, paints, inks, and so forth.
