Definitions

• This invention relates to fabric softening compositions containing a skin benefit agent such that when fabrics are treated with the fabric softening composition when in contact with the skin the fabrics deliver the skin benefit agent to the skin
• Rinse added fabric softener compositions are well known. Typically such compositions contain a water insoluble amine salt and/or a 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. Quaternary ammonium materials with long chain substituents have been used in fabric softening compositions for many years. Often they are used in conjunction with co-actives such as fatty acids or other relatively cheap materials which also provide softening benefits.
• fabric softening compositions desirably have other benefits.
