A water-based composition for enhancing shine or gloss in an elastomeric surface is in the form of a stable aqueous dispersion having a pH of from about 6 to about 7 and containing by weight: (a) less than 10% of at least one polydiorganosiloxane fluid; (b) from about 0.02% to about 2.0% of an alkali-swellable acrylic homopolymer or copolymer crosslinked with a polyalkenyl polyether; and (c) water. In one embodiment, the composition contains less than 1% by weight of a wetting agent and has no additional surfactants, hydrotropes and emulsifying agents. The composition can be used to enhance shine or gloss in elastomeric surfaces such as rubber or vinyl, preferably automotive tires, by applying an effective amount of the composition to the surface and distributing the composition with an application implement. The composition contains less organopolysiloxane than commercial formulations but exhibits gloss-enhancing performance that is comparable or even higher than that exhibited by commercial compositions.
