First Claim
Patent Images
1. A liquid rinse added or solid particulate rinse added fabric softening composition capable of reducing the transfer of dyes during subsequent wash cycles, comprising:
- I. from about 3% to about 90% of fabric softening agent; and
II. from about 0.03% to about 80% of water-soluble polymeric dye transfer inhibitor, selected from the group consisting of;
(A) polymers, which are not enzymes, with one or more monomeric units containing at least one ═
N--C(═
O)-- group having an average molecular weight of from about 500 to about 100,000;
(B) polymers with one or more monomeric units containing at least one N-oxide group having an average molecular weight of from about 500 to about 1,000,000;
(C) polymers containing both ═
N--C(═
O)-- and N-oxide groups of (A) and (B);
(D) mixtures thereof; and
wherein the composition is essentially free of aerosol propellant, bleach, sachets containing an active ingredient, and anionic surfactant; and
additionally when the composition is a liquid composition, and the fabric softening agent is methyl-1-oleylamidoethyl-2-oleylimidazolinium methosulfate, or analogous agent, the composition is essentially free of large amounts of highly ethoxylated material, propylated material, or mixtures thereof.

Abstract
The present invention relates to compositions and processes which incorporate water-soluble polymers, other than enzymes, containing ═N--C(═O)-- (including PVP) and/or N-oxide groups into the wash, rinse, and/or drying cycle of a laundering process (e.g., via fabric softening compositions) for dye transfer inhibition in the subsequent wash cycle. Multiple wash cycles optimize the dye transfer inhibitor performance of these polymers, remove unwanted dye discoloration caused by dye transfer, and provide soil antiredeposition benefits.
