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 fabriccleaning benefit.
- Laundry compositions 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.
- builders such as zeolite, silicates and carbonates, are incorporated into the composition. These builders sequester free calcium and magnesium cations. In addition to its role as builder the carbonate and silicate builders also increase the pH of the wash liquor which is beneficial at removing stains.
- a solid laundry detergent composition comprising an anionic detersive surfactant having a good fabric-cleaning performance, especially a good particulate, oily and greasy stain cleaning performance, good whiteness maintenance, and very good dispensing and dissolution profiles while the composition has low levels of alkaline builders.
- a solid laundry detergent composition that comprise an anionic surfactant, low carbonate levels and preferably low silicate levels, while maintaining excellent cleaning performance. It is also desired to provide a solid laundry detergent composition with a pH from 7 to 10.5 which provides benefits such as low or no deposition of residues on fabrics and associated improvement in whiteness, improved bleachable stain removal benefits.
- US 2018/0094219 A1 discloses a solid free flowing particulate laundry detergent composition for providing good cleaning performance.
- the laundry detergent composition has a low pH and includes 0 wt.% to 8 wt.% sodium carbonate, anionic surfactant and the composition has a pH in the range from 6.5 to 9.
