Abstract
The present invention is directed to litter compositions including a litter substrate in the form of granules and a stable fragrance coating applied over at least some of the litter granules. The stable fragrance coating provides a fragrance litter composition exhibiting no or a reduced tendency for fragrance to be lost over time. Furthermore, the fragrant litter composition is able to reform a stable fragrance coating after being wetted, upon redrying. The stable fragrance coating comprises a nanoemulsion including an aqueous surfactant continuous phase and a dispersed phase comprising one or more fragrance oils. The fragrance oil is dispersed within the continuous phase as nano-sized droplets having an average diameter of no more than about 100 nm.
