Liquid hand dishwashing detergent
First Claim
1. A dishwashing detergent composition comprising an anionic surfactant mixture containing at least two different anionic surfactants, a polyethylene glycol, water, and a phase stabilizer selected from the group consisting of a hydrotrope, an inorganic salt, and mixtures thereof, wherein said dishwashing detergent composition is essentially free of alkyl polyglucoside surfactants and the polyethylene glycol having a molecular weight ranging from about 400 to about 1000 comprises from about 0.5 to 10 weight percent of the dishwashing detergent.

Abstract
The invention relates to a class of detergent compositions for use in hand dishwashing that provides excellent performance as measured by persistence of foam in the presence of oily and fatty types of soils. Testing based on escalating amounts of such soils to the extinction of the foam showed surprising advantage of hand dishwashing composition comprising at least two anionic surfactants and a polyethylene glycol and being essentially free of alkyl polyglucosides.
