Definitions
- the present invention relates to the use of a biodegradable quaternary ammonium material as a soil release agent, for example, in a fabric conditioning composition.
- Rinse added fabric softener compositions are well known. Typically such compositions contain a water insoluble quaternary ammonium fabric softening agent dispersed in water at a level of softening agent up to 7% by weight in which case the compositions are considered dilute, or at levels from 7% to 50% in which case the compositions are considered concentrates.
- fabric softening compositions desirably have other benefits. One is the ability to confer soil release properties to fabrics, particularly those woven from polyester or cotton fibres.
- Soil release properties are generally imparted to fabrics by the use of a separate soil-release agent, usually a high molecular weight polymer, in a detergent composition or separate treatment.
- a separate soil-release agent usually a high molecular weight polymer
- a cationic polymeric soil release agent for use in a fabric conditioning composition.
- a disadvantage of such compositions is that the soil release agent increases the number of components in the formulation, increasing cost and making the product less environmentally acceptable.
