This invention discloses a stable, surfactant-free, aqueous hypochlorite paste readily dispersible in hot or cold water, thickened with non-reactive inorganics without having alkali metal silicates, providing up to 10% available chlorine and with a viscosity ranging from about 25,000 to about 2,000,000 CPS.

Surfactant free stable hypochlorite paste

This invention discloses a color stabilized aqueous detergent composition comprising in percent by weight of the composition (a) about 0.25% to about 95% surfactant; (b) about 0.0001% to about 0.5% dye; and (c) about 0.1% to about 5% polyhydroxy carboxylic acid or a salt thereof whereby color fading of said dye in said composition is substantially prevented.

Dye stabilized detergent compositions

An alkaline composition and method of cleaning aluminum surfaces is disclosed which avoids discoloring or tarnishing of the metal surface. The composition comprises a mixture of alkali metal metasilicate and a compound chosen from the group consisting of sodium carbonate, potassium carbonate, lithium carbonate, potassium orthophosphate and sodium orthophosphate and mixtures thereof, wherein the metasilicate salt is present in an effective amount up to about 3% by weight of the composition and wherein the pH ranges above about 12.0.

Alkaline cleaning compositions non-corrosive toward aluminum surfaces

This invention discloses a liquid scouring composition comprising in percent by weight of the composition (a) about 0.5% to about 5% anionic surfactant; (b) about 0.5% to about 5% amphoteric surfactant; (c) about 5% to about 65% abrasive; (d) about 0.1% to about 8% electrolyte; (e) 0% to about 5% other ingredients; and (f) water to make 100%.

Phosphate free liquid scouring composition

Aqueous solutions containing alkylamido betaines and certain water-soluble inorganic or organic salts provide compositions of remarkably high viscosities. The inorganic salts suitable for this purpose are the sulfates of metals from Groups IA, IIA, IIB, and IIIA of the period table; sulfates of non-metallic ions; and alkali metal carbonates. Organic salts suitable in the present compositions include the citrates, tartrates, succinates, and carboxymethyloxysuccinates of metals from Groups IA, IIA, IIB and IIIA of the period table and the citrates, tartrates, succinates and carboxymethyloxysuccinates of ammonium ions. These salts have a synergistic viscosity-building effect on aqueous compositions containing alkylamido betaines in combination with micelle-forming anionic surfactants. Other salts increase the viscosity of aqueous solutions containing alkylamido betaines only in the presence of anionic surfactants. Suitable inorganic salts in this category include sulfates of metals from Group IB of the period table; alums; alkali metal sesquicarbonates; alkali metal tripolyphosphates and pyrophosphates; salts of halogen acids selected from the group consisting of potassium chloride and ammonium chloride; and alkali metal silicates. Suitable organic salts in this category include alkali metal salts of acetic acid and alkali metal salts of nitrilotriacetic acid.

Viscous compositions containing amido betaines and salts

A liquid dishwasher composition is disclosed with sufficiently high viscosity for convenient use and good flow properties. The composition contains a natural, biopolymeric or synthetic gum thickener and a polyhydric alcohol and urea for viscosity and flow control.

Aqueous high viscosity liquid dishwasher compositions

Pourable, stable, liquid, abrasive compositions capable of removing manganese-ion derived discolorations from hard surfaces comprising a solid phase homogeneously dispersed and stabilized within an aqueous liquid phase are disclosed. Said solid phase comprises a water insoluble abrasive material. Said liquid phase comprises a stabilizing mixture, of a tertiary mixture of synthetic anionic surfactant, soap, and a nonionic surfactant, and an electrolyte system, said system comprising a stain removing amount of at least one electrolyte selected from the group consisting of an alkali metal salt of dihydroxy maleic acid, an alkali metal salt of dihydroxy tartaric acid, and mixtures thereof.

Stable liquid abrasive composition suitable for removing manganese-ion

Manganese ion-derived discolorations are removed from hard surfaces by the use of either dihydroxy maleic acid, dihydroxy tartaric acid, their alkali metal salts, or mixtures thereof. The non-toxicity and non-corrosivity of the disclosed compounds make them particularly suitable for household applications.

Method and compositions for removal of hard surface manganese

A method is disclosed for the agglomeration of chlorocyanurates. The method involves contacting said chlorocyanurates with salts that are non-reactive with it. The chlorocyanurate particles so treated have an increased storage stability and a significantly decreased tendency to segregate when ultimately mixed with a detergent base.
