The present invention relates to improved ophthalmic solutions that employ select B vitamins; pyridoxine and its salts; and thiamine and its salts in order to more effectively preserve solutions and to reduce the degree to which cationic preservatives will deposit on contact lenses. Ophthalmic solutions are here understood to include contact lens treatment solutions, such as cleaners, soaking solutions, conditioning solutions and lens storage solutions, as well as wetting solutions and in-eye solutions for treatment of eye conditions.

A composition of matter for impregnation into disposable wipes for use on athletic indoor shoes such as volleyball or basketball shoes that is quick, drying, made from natural ingredients, is gentle on human skin and that does not erode the sole of shoe or damage the protective coating on indoor athletic courts. The composition uses the unique choice of an undecane/tridecane blend combined with specific percentages of water, natural surfactants, natural oils and natural based light volatile alkane hydrocarbon blend that combined cleans rubber soles, is quick drying and has low interaction with flooring when shoes are worn on an athletic court.

Aqueous formulations comprising (A) at least one organic complexing agent selected from (A1) alkali metal salts of aminopolycarboxylic acids and (A2) polymers bearing at least two CH.sub.2N(CH.sub.2COOH)-units per molecule, partially or fully neutralized with alkali, (B) at least one salt of at least one of the following acids: nitric acid, sulphuric acid, sulphamic acid, methanesulfonic acid, C.sub.1-C.sub.2-carboxylic acids, C.sub.2-C.sub.4-hydroxymonocarboxylic acids, C.sub.2-C.sub.7-dicarboxylic acids, unsubstituted or substituted with hydroxyl, and C.sub.4-C.sub.6-tricarboxylic acids, each unsubstituted or substituted with hydroxyl, (C) at least one compound selected from (C1) phosphoric acid C.sub.2-C.sub.10-monoalkyl esters, (C2) a C.sub.3-C.sub.10-alkynol, optionally alkoxylated with one to 10 alkoxide groups per hydroxyl group, and (C3) a C.sub.4-C.sub.10-alkynediol, optionally alkoxylated with one to 10 alkoxide groups per hydroxyl group, said aqueous formulations having pH values in the range of from 7.5 to 10.

Acidic viscoelastic cleaning compositions are disclosed which use non polymer thickening agents. According to the invention, cleaning compositions have been developed using viscoelastic surfactants in acidic cleaning formulations. These provide the dual benefit of thickening as well as an additional cleaning, thereby improving performance. Applicants have also identified several pseudo linking agents which when, used with viscoelastic surfactants provide enhanced viscoelasticity and cleaning.

Solid rinsing, cleaning and/or sanitizing compositions for various applications are provided. In particular, solid compositions include a complex of urea and an acid having desirable storage stability previously unavailable in solid urea/acid compositions. Stable solid compositions are disclosed and methods of making the same to overcome conventional limitations associated with forming kinetically and thermodynamically stable solids that utilize urea/acid compositions.

A composition is disclosed for cleaning a membrane. The composition includes: (i) a non-ionic surfactant having the formula: RO(CH.sub.2CH.sub.2O).sub.nH, wherein R is a branched, substituted or unsubstituted, C.sub.11-15 alkyl group, wherein n is an average degree of ethoxylation, and wherein n is in the range of from 3 to 20; and (ii) at least one of an additional non-ionic surfactant, a water soluble solvent, or a hydrotrope. In one version of the composition, an upper limit of a range of molecular weights of the surfactant is 1300 grams or below. In another version of the composition, the composition has a gel point such that it will be in the liquid phase before and after dilution with any amount of water at all temperatures of 40 F. and above. A method of cleaning a membrane using the compositions is also disclosed.

Cleaning compositions include (a) a carrier liquid; (b) a metal citrate and/or a plurality of reagents configured to generate the metal citrate in situ; (c) one or a plurality of non-ionic surfactants; and (d) an organophosphate hydrotrope configured to increase solubility of the one or the plurality of non-ionic surfactants in the carrier liquid. Methods for cleaning engine cooling systems are described.

Chemical compositions may be used to dissolve coatings and at least partially encapsulate potentially hazardous fibers or potentially hazardous particles in the coating. The chemical composition for use in the removal of a textured or smooth surface comprising asbestos may comprise an aqueous solution comprising a surfactant package and triethyl phosphate. In certain embodiments, the surfactant package may comprise an alcohol ethoxylate surfactant and sodium lauryl sulfate.
