US Patent:

42243092, Sep 23, 1980

Filed:

Aug 24, 1979

Appl. No.:

6/069464

Inventors:

Abdul Gaffar - Somerset NJ
John J. Grecsek - Trenton NJ

Assignee:

Colgate-Palmolive Company - New York NY

International Classification:

A61K 722
A61K 716

US Classification:

424 54

Abstract:

An antibacterial oral composition effective to promote oral hygiene containing an antibacterial antiplaque agent which normally stains dental surfaces and an additive which reduces such staining without substantially diminishing the antibacterial and antiplaque activity of the agent. Bis-biguanido hexanes, such as chlorohexidine and alexidine, and quaternary ammonium salts, such as benzethonium chloride and cetyl pyridinium chloride are typical examples of antibacterial agents. The antistain additive is 2-phosphono-butane-1,2,4-tricarboxylic acid compound or an orally acceptable salt thereof.

US Classification:

Abstract:

Free flowing, zeolite-containing spray dried beads, useful for the manufacture of a particulate built syntyhetic nonionic organic detergent composition of reduced zeolite deposition characteristics due to the presence of bentonite and a low content of water soluble silicate or the absence of such silicate, include about 5 to 60% of water softening aluminosilicate (zeolite), about 2 to 40% of bentonite, about 5 to 60% of polyphosphate and up to about 5% of water soluble silicate. Preferably, for least zeolite deposition on the fabrics of laundry washed with the detergent composition, the spray dried beads contain no soluble silicate. Normally the moisture content of the beads will be in the range of about 3 to 12%, not being so high as to interfere with the flowability thereof (and of detergent compositions based on the beads) and not so low as to diminish the moisture content of the bentonite to a point at which it becomes less effective as an anti-deposition agent for the zeolite or zeolite-silicate aggregate and does not disperse readily in wash water. In addition to the polyphosphate, which serves as a very effective builder in these products, other water soluble builders may also be present. The invention also relates to nonionic detergent compositions based on such beads, which may be made by spraying such a nonionic detergent onto the beads so that it is absorbed by them.
