1. A multi-phase personal care composition comprising:

(a) an aqueous phase comprising fatty acid amide and nonionic surfactant; and

(b) an oil phase,

wherein:

(i) the nonionic surfactant to the fatty acid amide is present in a weight ratio of at least 5:1;

(ii) the aqueous phase is visually distinct from and in physical contact with the oil phase;

(iii) the non-ionic surfactant comprises the condensation products of aliphatic alcohols having from 8 to 22 carbon atoms in either straight or branched chain configuration with ethylene oxide, condensates of alkylphenols having C₆-C₁₅alkyl groups with 5 to 25 moles of ethylene oxide per mole of alkylphenol, polyoxyethylene sorbitan fatty acid esters, alkyl glucoside, or a mixture thereof; and

(iv) the nonionic surfactant is different from the fatty acid amide.
