Disclosed is hair conditioning compositions comprising antidandruff agent wherein the hair conditioning composition is substantially free of the group selected from a chelating agent, methylchloroisothiazolinone, and methylisothiazolinone. The compositions comprise by weight: (a) from about 0.1% to about 15% of a high melting point fatty compound; (b) compounds selected of; (b1a) from about 0.1% to about 10% of an amidoamine having the following general formula: R<SUP>1</SUP>CONH(CH<SUB>2</SUB>)<SUB>m</SUB>N(R<SUP>2</SUP>)<SUB>2 </SUB>wherein R<SUP>1 </SUP>is a residue of C<SUB>11 </SUB>to C<SUB>24 </SUB>fatty acids, R<SUP>2 </SUP>is a C<SUB>1 </SUB>to C<SUB>4 </SUB>alkyl, and m is an integer from 1 to 4 ; (b1b) an acid selected from the group consisting of 1 glutamic acid, lactic acid, hydrochloric acid, malic acid, acetic acid, fumaric acid, 1 glutamic acid hydrochloride, tartaric acid, and mixtures thereof, at a level such that the mole ratio of amidoamine to acid is from about 1:0.3 to about 1:1; or (b2) the combination of; (b2a) from about 0.1% to about 10% of a cationic conditioning agent; and (b2b) from about 0.1% to about 10% of a low melting point oil having a melting point of less than 25° C.; (c) a safe and effective amount of an antidandruff agent; (e) a preservative system comprising, by weight of the entire composition, from about 0.1% to about 1.0% of benzyl alcohol, from about 0.1% to about 1.0% of phenoxy ethanol, from about 0.05% to about 1.0% of methyl paraben, and from about 0.05% to about 1.0% of mettryl paraben, and from about 0.01% to about 1.0% of propyl paraben; and (f) an aqueous carrier. |
