AI Technical Summary

Technical Problem

Existing concentrated laundry detergent compositions face challenges in maintaining appropriate viscosity profiles both before and after dilution, as they often experience radical changes when mixed with water, affecting their physical and functional performance.

Method used

A process involving the sequential addition of non-ionic surfactant after neutralized LAS acid, followed by rheology modifier, at specific temperature conditions, ensures stable micelle formation and viscosity management, resulting in isotropic compositions before and after dilution.

Benefits of technology

The process achieves a stable viscosity profile in concentrated and diluted laundry detergent compositions, ensuring effective cleaning performance and physical stability.
