Abstract
Described herein are anhydrous compositions including at least one oil phase and at least one non-ionic surfactant. The oil phase includes one or more linear (i.e., unbranched) fatty esters, such as cetyl palmitate. The oil phase can further include at least one branched fatty esters, such as ethylhexyl palmitate and/or isocetyl stearate.
