Abstract
This invention relates to a laundry care composition comprising a laundry care ingredient and a polymeric thiophene hueing agent.
Claims20
A laundry care composition comprising:
- (i) a laundry care ingredient;
- (ii) 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;
- and
- (iii) at least one of the following structures, or salts thereof:
- and
- wherein the laundry care composition imparts a whitening effect to a cellulose-containing textile article that is measurably greater than a polyester-containing textile article treated with the laundry care composition, wherein the whitening effect is measured via a whiteness index on each textile article,
- wherein the polymeric thiophene hueing agent contains at least one amide moiety.
7 more elements
A process for measurably improving a whitening effect on cellulose-containing textile articles, wherein the improvement is present in an amount that is greater than the amount observed on polyester-containing textile articles, wherein the process comprises the following steps:
- (a) Providing a cellulose-containing textile substrate,
- (b) Providing a polyester-containing textile substrate,
- (c) Exposing the textile substrates of steps (a) and (b) to a laundry care composition comprised of:
- (i) a laundry care ingredient;
- and (ii) 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, C14 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;
- and
- wherein the polymeric thiophene hueing agent contains at least one amide moiety;
- and
- (iii) at least one of the following structures, or salts thereof:
- and
- (d) Measuring the whitening effect via evaluation of the whiteness index of each textile article.
11 more elements
A textile article, wherein the textile article contains:
- (a) a majority by weight of cellulose fiber, and
- (b) a laundry care composition comprising:
- (i) a laundry care ingredient;
- (ii) from 0.0001 wt % to 1.0 wt % of a polymeric thiophene hueing agent having the structure of Formula III:
- and (iii) at least one of the following structures, or salts thereof:
