Abstract
An aqueous cleansing composition comprising a cationic surfactant, a nonionic surfactant, and a thickener comprising an alkoxylated methyl glucose ether, wherein a weight ratio of cationic surfactant to nonionic surfactant is greater than 0.9:1. The combination of the cationic:nonionic surfactant ratio with the alkoxylated methyl glucose ether thickener provides the composition with cold weather stability. Cold weather stability is observed when the composition remains transparent after cold storage.
