1. A liquid laundry composition consisting essentially of one or more cationic polymers and one or more anionic surfactants wherein the composition has a percent transmittance of greater than about 50 at 570 nanometers measured in the absence of dyes and contains less than about 2% anionic polysaccharide.

Abstract
Fabric and textile conditioning compositions containing particular combinations of cationic polymers and anionic surfactants are disclosed. The polymers are soluble or dispersible to at least 0.01% by weight in distilled water at 25° C., and must be present in an effective amount to yield a substantial conditioning benefit. A method of conditioning articles using the polymer/surfactant combinations is also disclosed.

14. A method for conditioning textiles comprising, in no particular order, the steps of:
-
a. providing a laundry detergent or fabric softener composition comprising at least one anionic surfactant and at least one cationic polymer, in a ratio and concentration to effectively soften and condition fabrics under predetermined laundering conditions;
b. contacting one or more articles with the composition at one or more points during a laundering process; and
c. allowing the articles to dry or mechanically tumble-drying them, wherein the softening parameter is greater than 40 and the composition comprises more than about 5% by weight of one or more anionic surfactants having an HLB of greater than about 4. - View Dependent Claims (15, 16, 17, 18, 19, 20)
