Abstract
Abstract A liquid detergent system having a controllable viscosity and clarity, including a water-soluble paraffin sulfonate and a water-soluble, higher alkane, ether sulfate. Control of the viscosity and clarity is accomplished by using a control system comprising a lower aliphatic alcohol and urea.
