Title
(EN) Process for making a detergent based composition
Abstract
(EN)

A process for making an anhydrous laundry liquid detergent base composition comprising detersive surfactant, the process comprising the steps of:

    • a) providing a pre-neutralized sulphate detersive surfactant syrup wherein at least 50% of the sulphate detersive surfactant is pre-neutralized with an organic neutralizing agent;
    • b) adding a neutralizing agent to the sulphate detersive surfactant syrup; and
    • c) adding a sulphonic detersive surfactant in acid form to the mixture resulting from step b).
