Claims24
An aqueous laundry care composition comprising a laundry care ingredient and from 0.0001 wt % to 1.0 wt % of a polymeric thiophene hueing agent having the structure of Formula I:
- wherein each A is independently selected from the group consisting of polyethyleneoxy, polypropyleneoxy, and polyethyleneoxy/polypropyleneoxy copolymers, and wherein each A is independently present in the range from 1 to 20 repeating units of polyethyleneoxy, polypropyleneoxy or polyethyleneoxy/polypropyleneoxy copolymers;
- wherein each R1 is independently selected from H, C1-4 alkyl, alkoxy alkyl, halogens, aryl, substituted alkyl or substituted aryl, —COR2, —CH2COH, —COOR2, —COOH, —SO3H, —CH2COOH, —CH2CH2Cl, —CH═CH2, —CH2CH(OH)2, and salts thereof;
- wherein each R2 is independently selected from C1-18 alkyl, aryl, substituted aryl, and substituted alkyl.
An aqueous laundry care composition comprising a laundry care ingredient and from 0.0001 wt % to 1.0 wt % of a polymeric thiophene hueing agent having the structure of Formula I:
- wherein each A is independently selected from the group consisting of polyethyleneoxy, polypropyleneoxy, and polyethyleneoxy/polypropyleneoxy copolymers, and wherein each A is independently present in the range from 1 to 5 polyethyleneoxy, polypropyleneoxy or polyethyleneoxy/polypropyleneoxy copolymers repeating units;
- wherein each R1 is independently selected from H, and C1-4 alkyl.
An aqueous laundry care composition comprising a laundry care ingredient and from 0.0001 wt % to 1.0 wt % of a polymeric thiophene hueing agent having the structure of Formula II:
- wherein each A is independently selected from the group consisting of polyethyleneoxy, polypropyleneoxy, and polyethyleneoxy/polypropyleneoxy copolymers, and wherein each A is independently present in the range from 1 to 5 polyethyleneoxy, polypropyleneoxy or polyethyleneoxy/polypropyleneoxy copolymers repeating units.
A method for making an amide-containing, polymeric thiophene hueing agent, wherein the amide is formed via hydrolysis of a nitrile under basic conditions.
