Definitions
- the present invention relates to a solid laundry detergent composition, more particularly it relates to a solid laundry detergent composition comprising low levels of alkaline builders.
- Consumers of solid laundry detergent compositions desire that the laundry composition provides good fabric cleaning performance against a wide variety of soil types and also has very good dispensing and dissolution profiles. Especially consumers who handwash fabrics also desire for a laundry composition which is less harsh on hands and on fabrics.
- Laundry detergent composition for cleaning fabrics have been known for many years to include anionic detersive surfactant, particularly linear alkyl benzene sulphonate anionic surfactant.
- Formulators of the detergent composition incorporate anionic detergents into solid laundry detergent composition in order to provide a good fabric cleaning benefit.
- Laundry composition are generally added to water to form a solution, the water usually includes free cations, such as calcium and magnesium cations, these interact negatively with the anionic detersive surfactant and lead to a reduction in the anionic detersive surfactant activity.
- free cations such as calcium and magnesium cations
- builders such as zeolites, silicates and carbonates, are incorporated into the composition. These builders sequester free calcium and magnesium cations.
- the carbonate and silicate builders also increase the pH of the wash liquor which is beneficial at removing stains.
