Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
An anti-dandruff shampoo comprising an aqueous detergent base in liquid or paste form and an amount sufficient to provide effective anti-dandruff control on the hair and scalp of a salt or complex of a metal selected from the group consisting of lithium, sodium, potassium, zinc, calcium, tin, copper, antimony, lead, manganese, and aluminum of a compound having the following structural formula in tautomeric form: ##SPC5## wherein R 1 and R 2 are each independently selected from the group consisting of hydrogen, alkyl of one to 24 carbon atoms, phenyl, phenyl substituted with chlorine or methyl, halogen, trifluoromethyl and alkoxy
