Antidaudruff hair conditioning composition

Abstract

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<1> CONH (CH2)m N(R<2>)2 wherein R<1> is a residue of C11 to C24 fatty acids, R<2> is a C1 to C4 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 DEG 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.

[0002] Various methods have been developed to condition hair. These methods range from applying hair conditioners after shampooing, such as leave-on and rinse-off products, to hair conditioning shampoos which attempt to cleanse and condition the hair with the same product.
