Abstract
Abstract Detergent compositions containing a synthetic organic nonsoap detergent and an organo-phosphorus softener compound which provide conjoint cleaning and softening properties are described. The organo-phosphorus compounds employed in an amount of about 1 to 15 percent of the composition include alkylphosphinic compounds having the formula WHEREIN R is alkyl of about 12 to 30 carbon atoms, R1 is hydrogen or alkyl of one to about 30 carbon atoms, and M is a water-solubilizing cation, e.g., hydrogen, alkali metal, ammonium or substituted-ammonium or alkyl of about one to about eight carbon atoms; and alkyldiphosphonic compounds having the formula
