Solvent-free super concentrated liquid detergent is a green liquid detergent with more than 65% of active ingredients and without organic solvents. A new vegetable oil based surfactant, which has much lower freezing point than most of commercial ones and shows no viscous gel phase in aqueous solution in an extensive range of concentration, is added to help improve the performance of other ingredients and to provide the product with better performance at low-temperature such as smooth preparation procedure, good stability and solubility as well as easy use. At least 5-10% of rinsing water is saved because of less foam and easy rinse during washing. 

This solvent-free super concentrated liquid detergent is environmentally friendly. Without addition of auxiliary that might pollute the environment, it reduces greatly the chemical residues in wastewater. Compared with the commercial detergents in the market, this super concentrated product gives both manufacturer and consumer high economic and social benefits.
