A laundry detergency boosting polymer blend additive is made up of:

Detergency boosting polymer blends as additives for laundry formulations

An alkyl and/or aryl silyl ether capped polyether surfactant useful in cleaning compositions. The polyether is described in conjunction with automatic dishwashing detergent composition having improved chlorine bleach stability comprising:

Stable alkyl and/or aryl silyl ether capped polyether surfactants for

Cleaning compositions, especially liquid detergent compositions containing chlorine bleach, are disclosed. The compositions include a chlorine bleach stable nonionic surfactant which is a mixture of the formula

Sterically hindered polyether polyols as chlorine bleach stable

Relates to deodorizing a polyoxypropylene group terminated polyoxyalkylene polyether polyol composition by removing allyloxypropan-2-ol in sufficient amount to reduce the content to less than 200 ppm.

Low odor surfactant

The instant invention relates to a composition comprising a Bisphenol initiated polyoxyalkylene compound, a chlorine releasing compound and water. The Bisphenol initiated alkylene oxide compound is believed to be a cogeneric mixture of polymers denominated by the following formula ##STR1## Wherein A comprises oxyethylene and C.sub.3 -C.sub.5 oxyalkylene groups to form either a heteric or block copolymer; m is a whole number selected to give an overall average molecular weight of the product of 1100 to 15,000, and X is CH.sub.3 or C.sub.2 H.sub.5. The preferred compounds are oxyalkylated Bisphenol block copolymers believed to be a cogeneric mixture of polymers denominated by the following formulas: ##STR2## Wherein X is CH.sub.3 or CH.sub.2 H.sub.5, y is 3 or 4, m and n are whole numbers selected to give an overall molecular weight from about 1100 to 15,000 and a percent of oxyethylene groups from about 10 to 9. This composition has varied uses as a fabric cleaner with bleaching properties and a warewashing composition having a minimum of odor problems. Accordingly, in addition to the above components the invention relates to compositions which may be also contain conventional ingredients for such compositions.

Detergent composition

A low phosphate machine dishwashing composition comprising an admixture of by weight about 7 to 8 percent of a maleic acid-acrylic acid copolymer, about 10 to 20 weight percent of an alkaline condensed phosphate salt, about 2 to 4 percent of a blend of ethylene oxide-propylene oxide block copolymers and about 20 to 40 percent of an alkaline carbonate.

Dishwashing composition

Machine dishwashing detergents are disclosed containing a low-foaming nonionic surfactant having relatively low cloud point which unexpectedly provides effective detergency, foam control and good rinsing action when utilized as the sole nonionic surfactant. Dishes and other utensils are cleaned to a sparkling clean spot-free condition by the machine dishwashing detergent compositions of the invention containing conventional phosphate builders or non-phosphate builders but excluding conventional alkyl phosphate ester defoaming agents. The machine dishwashing detergent compositions of the invention are effective especially in controlling foam on washing dishes and other utensils encrusted with soils generally encountered on dishes, specifically egg and milk-derived protein soils.
