Per CalRecycle, please do not put unmedicated lotions, cosmetics, fragrances, sunscreen agents, and similar products down the drain or into the toilet; the best "somewhere else" to throw these items is your household trash. Landfills are the best place at present to dispose of personal care products when they are no longer being used. Click here for medicated lotions, creams and shampoos, and here for nail polish.
