Abstract
Aqueous oil-in-water emulsion scratch cover compositions for covering scratches, blemishes and other damage to finished wooden articles such as furniture, wooden trim and wooden floors with characteristics comparable to volatile organic solvent-based scratch cover compositions are described which are substantially free of added volatile organic solvents and conventional surfactants. These emulsion compositions comprise 2-10% of an animal, vegetable or mineral oil that is a liquid and substantially nonvolatile at 25.degree. C., 0.0001-1% of at least one organic solvent soluble dye that is soluble in the oil and is substantially water insoluble, an effective amount, preferably 0.01-5%, of a polymeric electrostatic emulsifier such as an acrylates/C.sub.10 -C.sub.30 alkyl acrylate cross polymer that takes the place of conventional surfactants with the balance comprising water, and optionally, non-ionic waxes, nonionic nonvolatile silicone fluids, pigments or no more than about 1% of nonionic surfactants.
