A water-dispersible or water-soluble composition comprising one or more water-dispersible or water-soluble star polymers, wherein the one or more star polymers comprises:
- (a) a core comprising C1-6 linear, branched, or cyclic hydrocarbon having at least two reactive groups;
- (b) two or more arms radiating out from the core, each arm having the following Formula 1:
- —[O—C(═O)—N(H)—R1-N(H)—C(═O)—O—(CH2CH2-O)n]—H
- wherein n=4-12, R1 is the same or different and is dicyclohexylmethane, diphenylmethane, or toluene.
A cleaning composition comprising about 0.01% to about 50% by weight of at least one water-dispersible or water-soluble composition, wherein the water-dispersible or water soluble composition comprises one or more water-dispersible or water-soluble star polymers, wherein the one or more star polymers comprises:
- (a) a core comprising C1-6 linear, branched, or cyclic hydrocarbon having at least one reactive group;
- (b) one or more arms radiating out from the core, each arm having the following Formula 1:
- —[O—C(═O)—N(H)—R1-N(H)—C(═O)—O—(CH2CH2—O)n]—H
- wherein n=4-12, R1 is the same or different and is dicyclohexylmethane, diphenylmethane, or toluene.
A light duty liquid detergent composition comprising about 0.01% to about 10% of the water-dispersible or water-soluble composition, wherein the water-dispersible or water soluble composition comprises one or more water-dispersible or water-soluble star polymers, wherein the one or more star polymers comprises:
- (a) a core comprising C1-6 linear, branched, or cyclic hydrocarbon having at least one reactive group;
- (b) one or more arms radiating out from the core, each arm having the following Formula 1:
- —[O—C(═O)—NH—R1-N(H)—C(═O)—O—(CH2CH2—O)n]—H
- wherein n=4-12, R1 is the same or different and is dicyclohexylmethane, diphenylmethane, or toluene.
A glass cleaner composition comprising about 0.01% to about 0.1% of the water-dispersible or water soluble composition, wherein the water-dispersible or water soluble composition comprises one or more water-dispersible or water-soluble star polymers, wherein the one or more star polymers comprises:
- (a) a core comprising C1-6 linear, branched, or cyclic hydrocarbon having at least one reactive group;
- (b) one or more arms radiating out from the core, each arm having the following Formula 1:
- —[O—C(═O)—N(H)—R1-N(H)—C(═O)—O—(CH2CH2-O)n]—H
- wherein n=4-12, R1 is the same or different and is dicyclohexylmethane, diphenylmethane, or toluene.
