Definitions

  • the present invention relates to a liquid detergent composition for textile products.

  • liquid detergent compositions As part of efforts toward a sustainable society, there is a demand for a reduction in the content of petroleum-derived surfactants in liquid detergent compositions for textile products (hereinafter, simply referred to as "liquid detergent compositions"). Reducing the surfactant content is also useful for reducing the amount of water used in washing. However, simply reducing the surfactant content reduces the cleaning power. Also, simply reducing the surfactant content reduces the viscosity of the liquid detergent composition. When the viscosity of the liquid detergent composition is reduced, the fluidity increases significantly, making the measurement process complicated.
