Makeup removal kit for long-wearing products
US Patent 8241617
Publication date: Aug. 14, 2012
Assignee: L'Oréal

According to this patent, many long-wearing and transfer resistant cosmetics form a film after application; these cosmetics generally contain volatile solvents that evaporate on contact with the skin or other keratinous tissue, leaving behind a film or layer comprising waxes and/or resins, pigments, fillers and actives. Removal of such transfer resistant compositions has been problematic. Typically, solvent-based, i.e., mineral oil, or volatile oils have been used. However, this typically leads to a harsh, somewhat abrasive removal process. Thus, there remains a need for improved methods for removing long-wearing cosmetic compositions.
