Leuco colorants as bluing agents in laundry care composition

A laundry care composition comprising:

• (a) at least one laundry care ingredient and (b) a leuco composition obtained from the following steps:
• (i) providing one molar equivalent of an aromatic aldehyde, (ii) providing approximately two molar equivalents of an aryl coupler or mixture of aryl couplers wherein at least one aryl coupler comprises a covalently bound oxyalkylene or polyoxyalkylene moiety, wherein the oxyalkylene or polyoxyalkylene moiety comprises at least one ethylene oxide group and at least one propylene oxide group, (iii) combining said aromatic aldehyde and aryl coupler(s) in a suitable reaction vessel, (iv) adding between 0.01 and 0.5 equivalents of urea, (v) adding muriatic acid to achieve a pH of between about 0 and 3, (vi) heating the mixture between 60° C. to 120° C. for between 2 hours to 12 hours, (vii) adjusting the pH to at least about 7, and (viii) separating at least a portion of the salts formed upon neutralization from the liquid product;
• wherein said leuco composition comprises at least one leuco compound, the leuco compound comprising a leuco moiety and a alkyleneoxy moiety covalently bound to the leuco moiety, wherein the alkyleneoxy moiety comprises at least one ethylene oxide group and at least one propylene oxide group.
