- a carrier in an amount of between about 0.1% and 40.0% by weight;
- a longevity and substantivity enhancing agent in an amount of between about 0.1% and 20.0% by weight, said longevity and substantivity enhancing agent being selected from the group consisting of ethoxyldiglycol and a carboxylate-based emollient;
- and
- water in an amount of between about 5.0% and 95.0%,
