  • Patent number: 11672751
    Abstract: A hair care composition is disclosed comprising a cationically modified guar polymer having a cationic degree of substitution of from 0.35 to 0.70, an ethoxylated alkyl sulfate anionic surfactant having a formula RO(CH2CH2O)nSO3M, wherein R is an alkyl or alkenyl group having from 8 to 18 carbon atoms; M is a solubilising cation comprising sodium, potassium, 5 ammonium, substituted ammonium or mixtures thereof; n is the degree of ethoxylation of from 0.5 to 3 and from 0.01 to 10% by weight of an anti-dandruff agent selected from azole based anti-fungal agents, piroctone olamine, metal pyrithione salts, selenium sulfide or mixtures thereof; wherein the degree of substitution is measured using 1H NMR and the spectrum is recorded at 25° C.
    Type: Grant
