1. An article of manufacture to aid ironing of fabric, said article comprising a spray dispenser containing an aqueous composition comprising:
- (a) from about 0.001% to about 25%, by weight of said composition, of a polymer comprising carboxylic acid moieties;
(b) a carrier comprising water;
wherein said composition has a pH of from about 3 to about 7 and a viscosity of less than about 20 cP.

Abstract
Polymer compositions, while providing suitable wrinkle control, also tend to dispense poorly when sprayed. The present invention shows that when viscosity of polymer compositions is minimized spray dispensing improves. Several approaches to minimizing the viscosity of polymer compositions are disclosed. Methods of controlling wrinkles in fabrics comprise treating fabrics with a variety of polymer compositions following a variety of methods. Articles of manufacture comprise (1) a container or substrate, (2) a wrinkle controlling composition, and (3) a set of instructions.
