Surface active polymers as detergents
View Patent ↗Provided herein are compositions useful as detergents in cleaning a wide variety of substrates, including hard surfaces and laundry. The compositions contain a water-soluble polymer, which is a co-polymer between a polymerizable amide and a second, ethylenically-unsaturated monomer. The polymerizable amide itself is prepared from an amine-capped, alkoxylated alcohol by reaction with maleic acid anhydride. Compositions according to the invention show enhanced cleaning performance and beneficial anti-redeposition properties.
1. A composition of matter useful as a detergent which comprises:
a) a first component which is a polymer that is formed from the co-polymerization of:
i) a first monomer having the structure:
in which R 1 and R 2 are each independently selected from the group consisting of: hydrogen, and any C 1 to C 24 hydrocarbyl group; X 1 , X 2 , X 3 , X 4 , X 5 , X 6 , X 7 , X 8 in each occurrence are each independently selected from the group consisting of: hydrogen, ethyl, and methyl; M + is selected from the group consisting of: hydrogen, alkali metal ions, an alkaline earth metal ions, ammonium ions, alkyl-substituted ammonium ions, and hydroxyalkyl-substituted ammonium ions; m, n, p, q are each independently any integer in the range of between 0 and about 50, including 0 and 50, subject to the proviso that at least one of m, n, p, q are not zero; and
ii) a second monomer, which is prepared from a polyethylene glycol having a methyl end cap and an ethylenically-unsaturated monomer selected from the group consisting of: acrylic acid and methacrylic acid; and
b) one or more second component(s) useful in formulating soaps, cleaning compositions, hard surface cleaners, and laundry detergents.
2. A composition according to claim 1 wherein the weight average molecular weight of said polymer is any value in the range of between about 3,000 and 100,000.
3. A composition according to claim 1 further comprising an effective amount of water for dissolving said polymer, so as to provide an aqueous solution comprising said polymer.
4. An aqueous solution according to claim 3 wherein said polymer is present in any amount between about 0.1 and about 10% by weight based on the total weight of said solution.
5. A composition according to claim 3 wherein p=0, q=0, n=0, m is about 3, R 2 is hydrogen; R 1 is any C 8 to C 20 hydrocarbyl group; and at least one of X 1 , X 2 , X 3 , or X 4 is hydrogen.
6. A composition useful as a detergent which comprises:
a) a polymer having a weight-average molecular weight of any value in the range of between about 3,000 to 100,000, which polymer includes in its structure a plurality of units described by the formula:
in which X is selected from the group consisting of: oxygen and —NR 4 —, the sum of p and q is any value between about 1 and about 100, including 1 and 100, wherein R 1 is independently selected from the group consisting of: hydrogen, and any C 1 to C 20 hydrocarbyl group; R 2 and R 3 may each be the same or different, and when the same they are selected from the group consisting of: any C 1 to C 6 alkyl group, and when R 2 and R 3 are different they are each independently selected from the group consisting of: any C 1 to C 6 alkyl group; R 4 is independently selected from the group consisting of: hydrogen, and any C 1 to C 6 alkyl group; R 5 is H and R 6 is H −
in which R 7 is selected from the group consisting of: hydrogen, methyl, and ethyl; and wherein n is sufficient to yield a weight average molecular weight of said polymer of any value in the range of between about 3,000 and 100,000, including salts thereof; M + is selected from the group consisting of: hydrogen, alkali metal ions, an alkaline earth metal ions, ammonium ions, alkyl-substituted ammonium ions, and hydroxyalkyl-substituted ammonium ions; and
b) at least one material useful in formulating soaps, cleaning compositions, hard surface cleaners, and laundry detergents.
7. A composition according to claim 6 further comprising an effective amount of water for dissolving said polymer, so as to provide an aqueous solution comprising said polymer.
