  • Patent number: 9526925
    Abstract: The present disclosure provides a composition that maintains a high and desirable viscosity while having a high amount of alcohol. Suitable thickeners and gelling agents are mixed with the alcohol to achieve this effect. An emulsion stabilizer can also be added. These components can also be combined with a sunscreen. The resulting composition provides benefits such as cooling and desirable skin feel, but is still easily spreadable and viscous enough to function effectively as a sunscreen.
