Abstract
Rinse aid compositions, methods of use, and methods of making said composition are disclosed. The rinse aid compositions can be solid or liquid. The rinse aid compositions comprise a defoamer, a sheeting agent, and a terpolyer of maleic, vinyl acetate, and ethyl acrylate. Preferred sheeting agents include one or more alcohol ethyoxylates. Preferred defoamer components include a polymer compound including one or more ethylene oxide groups. The solid rinse aid compositions are preferably substantially free of sulfate and sulfate-containing compounds.
Claims20
A rinse aid composition comprising:
- a sheeting agent comprising one or more alcohol ethoxylates;
- a defoamer component comprising a polymer compound including one or more ethylene oxide groups;
- and
- a terpolymer of maleic, vinyl acetate, and ethyl acrylate monomers or alkali metal salts thereof, wherein the alcohol ethoxylate has a structure by the formula, R—O—(CH2CH2O)n—H, R is linear
- or branched C8-C15 alkyl group, and n is 1 to 25;
- the defoamer is a block copolymer having the formula (EO)x(PO)y(EO)x or (PO)y(EO)x(PO)y, wherein x is 1 to 130, and y is 5 to 70;
- and
- the composition is a rinse aid composition, not a detergent or cleaning composition.
A method for making a rinse aid composition comprising:
- mixing a sheeting agent comprising one or more alcohol ethoxylates, a defoamer component comprising a polymer compound including one or more ethylene oxide groups, and a terpolymer of maleic, vinyl acetate, and ethyl acrylate monomers or alkali metal salts thereof to form a mixture;
- forming a rinse aid composition,
- wherein the alcohol ethoxylate has a structure by the formula, R—O—(CH2CH2O)n—H, R is linear or branched C8-C15 alkyl group, and n is 1 to 25;
- the defoamer is a block copolymer having the formula (EO)x(PO)y(EO)x or (PO)y(EO)x(PO)y, wherein x is 1 to 130, and y is 5 to 70;
- and
- the composition is not a detergent or cleaning composition.
