AI Technical Summary
Technical Problem
Biosurfactants like rhamnolipids cause textile graying during washing, limiting their use in detergents, and cationic surfactants adhere to textile surfaces with dirt particles, forming complexes that prevent their desired effects.
Method used
A surfactant mixture comprising rhamnolipid, cationic, and non-ionic surfactants is developed, which reduces graying without forming insoluble precipitates.
Benefits of technology
The surfactant mixture effectively reduces laundry graying while maintaining cleaning performance, eliminating the need for polymeric graying inhibitors or optical brighteners.

Abstract
A surfactant mixture consisting of at least one rhamnolipid and at least one cationic surfactant and at least one non-ionic surfactant, as well as a detergent containing this surfactant mixture, can be used to reduce the greying of textiles washed with it.
