Abstract
A moist wax-impregnated towelette suitable for polishing a lightly-soiled exterior surface of a vehicle without buffing and without abrading the vehicle surface comprises a low-lint fabric such as melt-blown polypropylene non-woven fabric, impregnated with an aqueous silicone-based car wax emulsion in an amount of about 30 to about 170 grams of emulsion per square meter of fabric. The aqueous silicone-based car wax emulsion contains a isopropanol, a silicone oil, an amino-functional silicone, a cationic emulsifier, a nonionic emulsifier, an anti static agent, a silicone polyether wetting agent and optionally contains a wax such as carnauba wax. The wetting agent provides for even distribution of the aqueous car wax emulsion into the fabric and further promotes the even distribution of the car wax onto the vehicle surface when wiped thereon.
