Abstract
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.
Claims8
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 R1 and R2 are each independently selected from the group consisting of:
- hydrogen, and any C1 to C24 hydrocarbyl group;
- X1, X2, X3, X4, X5, X6, X7, X8 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.
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 —NR4—, the sum of p and q is any value between about 1 and about 100, including 1 and 100, wherein R1 is independently selected from the group consisting of:
- hydrogen, and any C1 to C20 hydrocarbyl group;
- R2 and R3 may each be the same or different, and when the same they are selected from the group consisting of:
- any C1 to C6 alkyl group, and when R2 and R3 are different they are each independently selected from the group consisting of:
- any C1 to C6 alkyl group;
- R4 is independently selected from the group consisting of:
- hydrogen, and any C1 to C6 alkyl group;
- R5 is H and R6 is H−
- in which R7 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.
