Abstract
A fabric softening composition which comprises a skin conditioning compound comprising a C8-C22 .alpha.-hydroxyacid or an ester of a .alpha.-hydroxyacid or mixtures thereof and a fabric softening compound. The fabric conditioner when used to condition fabrics causes the fabrics to condition skin when contacted therewith.
Description
Fabric Softenina Composition 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 7o by weight in which case the compositions are considered dilute, or at levels from 7~ to 50o 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.
In addition to softening, fabric softening compositions desirably have other benefits.
GB 1 601 359 ( Procter and Gamble ) and GB 1 550 205 (Procter and Gamble) describes the use of ester oil and silicones as an ingredient in a fabric softening composition as fabric lubricants suggested which may give ease of ironing benefits, and softening.
