## Abstract

Disclosed is a hair conditioning composition comprising: a cationic surfactant; a high melting point fatty compound; a preformed emulsion and/or an ionic benefit agent, wherein the ionic benefit agents are those excluding ionic dyes, precursors thereof, and anionic surfactants; an alkyl ether and/or alkyl ester, preferably alkyl ether, of at least one of the following: polyethylene glycol, polypropylene glycol, polyglycerin, and mixtures thereof, and wherein the alkyl ether and/or alkyl ester has from about 50 to about 300 units of ethylene glycol, propylene glycol, glycerin and mixtures thereof; and an aqueous carrier. The composition of the present invention provides benefits from ionic benefit agents and/or preformed emulsions, while maintaining stability and wet conditioning of the composition.

## Claims

### Claim 1

A hair conditioning composition comprising:
a cationic surfactant;
a high melting point fatty compound;
an ionic benefit agent, wherein the ionic benefit agent is from about 0.5 wt % to about 10 wt % of salicylic acid;
a stearyl ether of polyethylene glycol having from about 100 to about 200 units of ethylene glycol; and
from about 70 wt % to about 95 wt % of an aqueous carrier;
and wherein the composition is substantially free of anionic surfactants, wherein all concentration ranges are based on the total weight of the composition.
