Abstract
Abstract Cleaning compositions based upon higher fatty alcohol detergents such as sodium lauryl sulfate and having particular utility for removing soil and stains from carpets, upholstery, etc., and for imparting stain resistance to the cleaned surface are improved by the addition of certain anionic surfactants without which the compositions could cause respiratory irritation to an unprotected user, especially in unventilated closed areas.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
26 words
A composition in accordance with claim 1 wherein the weight ratio of higher fatty alcohol detergent: anionic surfactant is in the range of 1:1 to 1:3.
Claim 2
Dependent Claim
21 words
ammonium salt of hydrolyzed styrene/maleic anhydride copolymer anti-redeposition agent in an amount sufficient to impart soil resistance to said substrate; and
Claim 3
Dependent Claim
57 words
an anionic surfactant selected from the group consisting of: a. oleic acid ester of sodium isethionate; b. sodium N-cyclohexyl-N-palmitoyl taurate; c. sodium N-coconut acid-N-methyl taurate; and d. sodium N-methyl-N-oleoyl taurate in an amount sufficient to substantially eliminate the normal tendency of said cleaning composition on being atomized by spraying to cause respiratory irritation to an unprotected user;
Claim 4
Dependent Claim
22 words
an ammonium salt of hydrolyzed styrene maleic anhydride copolymer anti-redeposition agent in an amount sufficient to impart soil resistance to said substrate;
Claim 5
Dependent Claim
69 words
an anionic surfactant selected from the group consisting of a. oleic acid ester of sodium isethionate, b. sodium N-cyclohexyl-N-palmitoyl taurate, c. sodium N-coconut acid-N-methyl taurate, and d. sodium N-methyl-N-oleoyl taurate is an amount sufficient to substantially eliminate the normal tendency of said cleaning composition on being atomized by spraying to cause respiratory irritation to an unprotected user; and B. correspondingly from about 98 percent to about 50 percent water.
Claim 6
Dependent Claim
29 words
A composition in accordance with claim 1 wherein the weight ratio of anti-redeposition agent: (higher fatty alcohol detergent plus anionic surfactant) is in the range of 0.3:1 to 1:1.
Claim 7
Dependent Claim
17 words
A composition in accordance with claim 1 wherein the higher fatty alcohol detergent is sodium lauryl sulfate.
Claim 8
Dependent Claim
71 words
sufficient low boiling alkane or chloro-, fluoro- substituted alkane non-irritating aerosol propellant to expel the liquid contents of said vessel; and correspondingly from 95 percent to 98 percent water; the weight ratio of sodium lauryl sulfate to said anionic surfactant being in the range of 1:1 to 1:3 and the weight ratio of said anti-redeposition agent to sodium lauryl sulfate and anionic surfactant being in the range of 0.3:1 to 1:1.
Claim 9
Dependent Claim
43 words

Claim 12
Dependent Claim
88 words
A container-stable foaming sodium lauryl sulfate based aerosol aqueous cleaning composition having particular utility for removing soil and stains from a substrate such as a carpet and imparting soiling resistance to said substrate, which composition can readily be used in unventilated areas without causing respiratory irritation to an unprotected user, the composition being contained in a pressure-resistant closed vessel fitted with a valve means, said composition consisting essentially of from about 2 percent to about 5 percent non-aqueous components consisting essentially of a mixture of the following ingredients:
Claim 13
Dependent Claim
