Definitions
- the present invention relates to Fabric Softening compositions, in particular the invention relates to aqueous dispersions of biodegradable fabric softening compositions comprising a water insoluble cationic fabric softening agent, a stabilising agent and a fatty alcohol suitable as a rinse-added fabric softener 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 8% by weight in which case the compositions are considered dilute, or at levels from 8% 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 fibre. Other benefits include improved perfume delivery.
- Certain stabilising agents not only stabilise fabric softener composition comprising biodegradable quaternary ammonium compounds but are also environmentally friendly, in that they show acceptable biodegradability and are not substantially toxic in aquatic systems .
- the nonionic material acting to improve the viscosity characteristics of a product when the level of cationic material is above 8%.
- compositions can also include low levels of electrolyte such as respectively sodium chloride or calcium chloride, to further control product viscosity.
- EP 056 695 discloses compositions comprising 12.3-25% cationic fabric softener and ethoxylated amines.
- WO 92/15745 discloses compositions comprising 10-35% cationic fabric softener, a highly branched fatty alcohol and a fatty alcohol ethoxylate.
- GB 2 170 829 and EP 394 133 disclose compositions comprising 3-8% and 2-35% respectively cationic fabric softener that do not need non ionic surfactant emulsions to keep viscosity and stability acceptable.
- GB 2 139 259 and EP 122 141 disclose compositions comprising 8% or more cationic fabric softener and non ionic materials with an HLB of less than 10, e.g. fatty alcohols.
- EP 409 504 disclose compositions comprising cationic fabric softener and fatty alcohols as extenders for the softener.
- GB 1 538 094 discloses compositions comprising cationic fabric softeners, fatty alcohols and non-ionic emulsifiers.
