Abstract
The invention relates to a liquid laundry detergent composition suitable for cleaning textiles. In addition to at least one surfactant the detergent according to the invention comprises at least one water-soluble metasilicate, at least one water-soluble bicarbonate, at least one water-soluble glutamate and at least one polymeric rheology modifier in an aqueous medium. These components form a detergent framework allowing to reduce the amount of surfactant(s) compared to conventional liquid detergents, which is advantageous for economic, safety and environmental reasons, as less surfactants are consumed and subsequently disposed into wastewater to achieve the similar washing/cleaning performance.
