(54) Title: LIGHT DUTY LIQUID DETERGENT COMPOSITIONS
(57) Abstract:
An aqueous liquid detergent composition for hand washing soiled dishware includes specific narrow classes and amounts of magnesium or sodium alkyl benzene sulfonate surfactant, alkyl ether sulfate surfactant, C12-C16 alkyl polyglucoside and al keno' amide foam stabilizer. A higher alkyl sulfosuccinate or suHosuccinate, optionally etliox: ylated, anionic surfactant may also be present. The compositions are capable of generating a stable foam and are effective in cleaning greasy soils with acceptable mildness for the consumer and with good rinseability
 
VI.  TITLE:  Light Duty Liquid Detergent Compositions
VII. ABSTRACT
An aqueous liquid detergent composition for handwashing soiled dishware includes specific narrow classes and amounts of magnesium or sodium alkyl benzene sulfonate surfactant, alkyl ether sulfate surfactant, C12-C16 alkyl polyglucoside and alkanolamide foam stabilizer. A higher alkyl sulfosuccinate or sulfosuccinate, optionally etboxyIated, anionic surfactant may also be present. The compositions are capable of generating stable foam and are effective in cleaning greasy soils with acceptable mildness for the consumer and with good rinseability.

IX. CLAIM OF INVENTION

There are eight (8) claims
CLAIM 1
A liquid dishwashing detergent composition providing stable foaming characteristics and which is mild to the hands and is effective in removing greasy soils, said composition comprising:
(A) a surfactant system comprising
(1) from about 7.5 to 20% by weight of a salt of a C10-C16 linear alkyl benzene sulfonate anionic surfactant, said salt being selected from the group consisting of alkali metal salts, alkaline earth metal salts and mixtures thereof;
(2) from 0 to about 8% of anionic C 10C18 alkyl aulfosuccinate or sulfosuccinamate, wherein the alkyl group may be ethoxylated with up to 8 moles of ethylene oxide;
(3) from about 8 to 20% of anionic C10- C20 alkyl ether sulfate having from 1 to less than 3 moles ethylene oxide per mole of alkyl group; and
(4) from about 3 to 12% by weight of an alkyl polyglucoside having from 12 to 16 carbon atoms, on average, in the alkyl chain, and an average degree of polymerization in the range of from about 1 to about 3;
(B) from about 0.5 to about 6% by weight of a foam
stabilization system comprising at least one lower alkanolamide of higher alkanoic acid;
the total weight of components (A) and (B) ranging from about 25 to 54% by weight of the composition;
(C) up to about 10% by weight of a low irritant organic solvent;
(D) up to about 8% weight of hydrotrope;
(E) up to about 20% by weight in total of one or more optional additives chosen from chelating or sequestering agents, coloring agents, dyes, perfumes, bactericides, fungicides, preservatives, sunscreening agents, pH modifiers, pH buffering agents, opacifiers, antioxidants, thickeners, and proteins; and
(F) balance, water.
 
CLAIM 2
