International Classification:

C11D 3075
C11D 308
C11D 3395
C11D 1102

US Classification:

252 99

Abstract:

A free flowing, stable, water-soluble, powdered automatic dishwashing detergent with superior solubility, handling and storage characteristics is provided. The compositions comprises an inorganic polyphosphate carrier onto which is absorbed a nonionic detergent. The "loaded" carrier is mixed with powdered silicate and the other usual adjuvants such as bleach, pigment, etc. High levels of detergent are possible without adversely affecting the aforementioned advantages and superior characteristics.

International Classification:

C11D 708

US Classification:

252142

Abstract:

An acidic liquid detergent composition for cleaning ceramic tiles without eroding the grout between the tiles comprises minor proportions of partially neutralized glutaric acid, partially neutralized phosphoric acid, surface active condensation product of ethylene oxide and higher linear alcohol of 10 to 20 carbon atoms, such as the condensation product of a linear secondary alcohol averaging about 13 carbon atoms with about 20 moles of ethylene oxide, and mono-lower alkyl ether of diethylene glycol, such as the butyl ether of diethylene glycol, and a major proportion of water, with the pH of the composition being within the range of 3 to 5, preferably 4. The composition is found to be an excellent bathroom cleaner, being especially useful for cleaning soap scum and other soil from ceramic tile, porcelain ware, such as bathtubs and sinks, and from other hard surfaces. Tile cleaning is easily effected without erosion of the grout between the tiles, which is often experienced when other acidic cleaners are utilized. Within broader composition aspects of the invention are acidic cleaning compositions containing glutaric acid or a salt thereof, together with an acid or salt thereof, the calcium salt of which is water insoluble.

Assignee:

Colgate-Palmolive Co. - Piscataway NJ

International Classification:

C11D 314

US Classification:

252 99

Abstract:

Thixotropic aqueous liquid automatic dishwashing detergent composition with improved anti-filming and anti-spotting properties and method of using the detergent composition. The detergent composition comprises alumina or titanium dioxide anti-filming agent, polyacrylate polymer anti-spotting agent, inorganic builder salts, chlorine bleach, bleach-stable detergent and a thixotropic thickener. The compositions provide reduced filming and spotting on dishware, glassware, china and the like, particularly in hard water, and remain stable against phase separation.

US Classification:

252 99

Abstract:

The application is directed to a nonaqueous liquid automatic dishwasher detergent composition with improved anti-filming and anti-spotting properties and to a method of using the detergent composition. The detergent composition comprises a nonaqueous organic carrier liquid, silica, alumina or titanium dioxide anti-filming agent, a water soluble polyacylate anti-spotting agent, inorganic builder salts, bleach compound and detergent. The compositions provide reduced filming and spotting on dishware, glassware, china and the like, particularly in hard water. The nonaqueous liquid automatic dishwasher detergent compositions are stable in storage and are readily dispersible in water.

Appl. No.:

6/105817

Inventors:

Charles E. Buck - Caldwell NJ

Assignee:

Colgate-Palmolive Company - New York NY

International Classification:

B32B 518
B32B 702

US Classification:

428284

Abstract:

A water-in-oil emulsion at a ratio of 80/20 or less when incorporated into a water absorbing material (such as a polyurethane sponge) will aid in retaining water that may be subsequently added to the absorbing material. The effect is believed due to the increased viscosity of the emulsion when water is added. The effect is particularly useful for improving urine retention of diapers, such as disposable diapers or similar articles.
