AI Technical Summary
Technical Problem
Commercial sodium laureth ether sulfate (SLES) has high viscosity, making it difficult to handle, and its use as a blend with ethanol poses a fire hazard due to ethanol's low flash point.
Method used
A blend of an ionic liquid and an alcohol is added to SLES, significantly reducing its viscosity and allowing for safer handling, while minimizing the amount of flammable alcohol required.
Benefits of technology
The ionic liquid and alcohol blend synergistically reduces the viscosity of SLES, enabling easier processing and handling, while improving fire safety by reducing the amount of ethanol needed.
