Abstract

Abstract Compositions for cleaning hard surfaces, which are formulated to leave on the surface simultaneously with the cleaning thereof a protective barrier layer which serves to protect the surface against further soil deposition, comprising: (A), as cleaning agents, from one to two nonionic surfactants and an amphoteric surfactant; (B), as protective barrier components, lecithin and an aminofunctional polydimethylsiloxane copolymer; (C), as solvency and grease cutting agents, from one to two glycols; and (D) water.

Claims Analysis

Total Claims: 7

Claim 1

Independent Claim 253 words

A liquid cleaning composition for cleaning hard surfaces consisting essentially of: (A) (i) from 2.0 to 15.0 percent of from one to two nonionic surfactants selected from the group consisting of a polyethylene glycol alkylphenyl ether having the formula: ##STR6## where R 1 is C 8 -C 9 straight or branched chain alkyl and n is an integer from 5 to 13, a polyethylene glycol long chain alkyl ether having the formula: ##STR7## where R 2 is C 9 -C 15 straight chain or secondary alkyl and n has the meanings given above, a saturated or unsaturated fatty acid mono- or diethanolamide having the formulas IIIa or IIIb: ##STR8## and a saturated or unsaturated fatty acid monoisopropanolamide having the formula IIIc: ##STR9## where R 3 , in all instances is a C 9 -C 17 alkane, alkene or alkadiene group, and (ii) an amphoteric surfactant having the formulas IVa or IVb: ##STR10## where R 4 is C 6 -C 18 alkyl or alkenyl, ##STR11## where R 5 is C 11 -C 17 alkyl and m is one of the integers 2 and 3; (B) from 0.07 to 3.0 percent of lecithin and from 0.50 to 10.0 percent of an aminofunctional polydimethylsiloxane copolymer having the formula: ##STR12## (C) from 1.0 to 20.0 percent of from one to two glycols having one of the formulas VIa or VIb: ##STR13## where R 6 is hydrogen or C 1 -C 2 lower-alkyl and p is one of the integers 1 to 2; and (D) the balance water.
