Abstract

The present invention relates to an aqueous opaque hair conditioner which comprises a monoalkyl quat from C14 to higher Carbon chain lengths (preferably C16 to C22) and a dialkyl quat which is a mixture of C16, C16 dialkyl quat and C18, C18 dialkyl quat. Also included is an amount of fatty alcohol to opacify the conditioner. Optionally, a silicone compound may be included. The monoalkyl quat may be in a ratio to the dialkyl quat of about 15:1 to about 2:1. The carbon chain lengths within the dialkyl quat are present in a weight ratio of about 1:3 to about 3:1 of C16,C16 to C18, C18. The fatty alcohol may be present in an amount from about 1% to about 10%.
