Abstract
Abstract The invention relates to the use of one or more ethoxylated fatty amines corresponding to the following general formula <IMAGE> (I) in which n is an integer of from 2 to 30, R1 is a C8-24 straight-chain or branched-chain, saturated or unsaturated alkyl, and R2 has the formula -(CH2-CH2-O)m-H (II) or the formula <IMAGE> (III) where R3 is a C2-6 alkylene, and m, x, and y are each an integer of from 0 to 30, as solution promoters in detergent concentrates for detergent solutions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
100 words
A method for promoting the water solubility of detergent components in an aqueous concentrate wherein said detergent concentrate is formulated for the machine washing of bottles, comprising incorporating in said concentrate a solubility-promoting-effective amount of one or more ethoxylated fatty amines corresponding to the following general formula ##STR5## in which n is an integer of from 2 to 30, R 1 is a C 8-24 straight-chain or branched-chain, saturated or unsaturated alkyl, and R 2 has the formula ##STR6## where R 3 is a C 2-6 alkylene, and x, and y are each an integer of from 0 to 30.
Claim 2
Independent Claim
100 words
A method for promoting the water solubility of detergent components in an aqueous concentrate wherein said detergent concentrate is formulated for the machine washing of bottles, comprising incorporating in said concentrate a solubility-promoting-effective amount of one or more ethoxylated fatty amines corresponding to the following general formula ##STR5## in which n is an integer of from 2 to 30, R 1 is a C 8-24 straight-chain or branched-chain, saturated or unsaturated alkyl, and R 2 has the formula ##STR6## where R 3 is a C 2-6 alkylene, and x, and y are each an integer of from 0 to 30.
Claim 3
Dependent Claim
26 words
The method of claim 1 wherein R 2 is formula III and at least one of x or y is an integer of at least one.
Claim 4
Dependent Claim
17 words
The method of claim 2 wherein the sum of n+x+y is an integer from 2 to 15.
Claim 5
Dependent Claim
17 words
The method of claim 2 wherein the sum of n+x+y is an integer from 10 to 15.
Claim 6
Dependent Claim
41 words
The method of claim 1 wherein said one or more ethoxylated fatty amine is at least one adduct of cocosamine, tallow fatty amine, oleylamine, octadecylamine, tallow fatty oleylamine, stearylamine, or tallow fatty propylenediamine, with 2 to 15 mols of ethylene oxide.
Claim 7
Dependent Claim
35 words
The method of claim 1 wherein said one or more ethoxylated fatty amine is incorporated in said concentrate in a quantity of about 1 to 15% by weight, based upon the weight of said concentrate.
Claim 8
Dependent Claim
12 words
The method of claim 1 wherein R 1 is a straight-chain alkyl.
