Abstract:
An engine cleaner composition comprising:a single phase solution comprising: (i) a polar solvent having a Hildebrand solubility parameter of about 10 calÂ½ cm âˆ’3/2 or greater; (ii) a non-polar solvent, immiscible with the polar solvent, having a Hildebrand solubility parameter of about 10 calÂ½ cmâˆ’3/2 or less; and (iii) a fugitive cosolvent having a higher evaporation rate than the polar solvent and the non-polar solvent; wherein upon evaporation of the fugitive cosolvent, the polar solvent and non-polar solvent spontaneously separate into two immiscible phases.
