Improved mechanical dishwasher formulations are provided which are characterized by the use of a random copolyether foam control agent, and wherein the foam control agent imparts the desirable properties of cleaning and defoaming without the concurrent buildup of spots and films on the dishes. The foam control agent is a copolyether having a molecular weight of at least about 2000 and containing random propyleneoxy (and/or butyleneoxy) groups and ethyleneoxy groups. The amount of ethyleneoxy and propyleneoxy or butyleneoxy groups present in the copolyether is selected such that the cloud point of the foam control agent is equal to, or less than, the operating temperature of the mechanical dishwasher.

Random polyether foam control agents

The process for the stabilization of polycondensation catalysts and the stabilization composition used in such process for producing polyesters and copolyesters by the polycondensation of dicarboxylic acid and an aliphatic glycol using certain metal-containing polycondensation catalysts in conjunction with a stabilization composition formed as the reaction product of phosphoric acid, meta-phosphoric acid, superphosphoric acid or mixtures thereof and an aliphatic epoxide having between 2 and about 10 carbon atoms.

Stabilization of polycondensation catalysts

The process and the catalyst used therein for producing polyesters and copolyesters, useful for making films and fibers, by the polycondensation of dicarboxylic acids and aliphatic glycols using coordinations complexes of metal halides and silicon compounds as catalysts.

Coordination complexes as polyesterification catalysts

Organosilicone terpolymer containing a plurality of pendant polyoxyalkylene groups and a plurality of pendant hydroylzable silyl groups is employed as a hydrophilic finish agent for natural and synthetic textile fabrics.

Organosilicone terpolymers

Improved process for producing polyesters and copolyesters modified with certain polyoxyalkylene glycols employs coordination complex catalysts of (I) a metal halide compound and certain silicon compounds or (II) a mixture of said coordination complex catalyst of said compounds with antimony diglycollate.

Process for producing polyoxyalkylene glycol modified polyesters

Organosilicone terpolymers containing a plurality of reactive epoxy groups and a plurality of polyoxyalkylene groups are employed as hydrophilic softening agents for natural and synthetic textile fabrics.

Treatment of textile fabrics with epoxy-polyoxyalkylene modified

A process for producing polyesters and copolyesters, useful for making films and fibers, by the polycondensation of dicarboxylic acids and aliphatic glycols using coordinations complexes of metal halides and silicon compounds as catalysts.

Coordination complexes as catalysts

A process for producing polyesters and copolyesters, useful for making films and fibers, by the polycondensation of dicarboxylic acids and aliphatic glycols using mixtures of antimony diglycollate and silicon compounds as catalysts.

Process for catalytic production of polyesters

Silicone textile treating compositions containing as a flammability retarder a chelator, such as ethylenediamine tetraacetic acid or a salt, ether or ester thereof.

Composition for improving flame retardancy properties of textile fibers

A process for producing polyesters and copolyesters, useful for making films and fibers, by the polycondensation of dicarboxylic acids and aliphatic glycols using certain silicon compounds as catalysts.

Catalytic production of polyesters

Synthetic organic fibers, which have been silicone treated to improve other properties, are treated with certain chelators, such as, ethylenediamine tetraacetic acid and its salts, as flame retarders to reduce their flammability.

Textile fiber having improved flame retardancy properties

Paper and textile fabric substrates have been rendered water repellent by treatment of water-dispersible aqueous emulsions of epoxy-silicones where the emulsifying agent is an anionic sulfonate emulsifier, which is capable of forming stable aqueous emulsions of epoxy-silicones, which cure rapidly without curing catalysts.
