摘要： The instant disclosure relates hair care compositions comprising ionic liquids or ionic mixtures. Ionic liquids or ionic mixtures are combined with a cosmetically acceptable carrier to form ready-to-use hair care compositions. The ionic liquids and the ionic mixtures are formed from; (1) thiolactic acid and/or one or more alkali metal or alkaline earth metal salts thereof; and (2) one or more amine compounds, and/or one or more ammonium cationic compounds, and/or one or more salts thereof. The ionic liquids, the ionic mixtures, and the hair care compositions comprising the ionic liquids or the ionic mixtures, are useful in methods for preventing hair damage, shaping hair, caring for hair, etc.
