Claim 0:
1. A personal cleansing composition comprising:
a) an amidoamine surfactant of the formula:

R5R6N—(CH2)x—NHC(O)R7  (I), wherein R5 and R6 are independently methyl or ethyl, x is 2 or 3, and R7 is C6 to C30 alkyl, wherein R7 is saturated or unsaturated,
b) 5 to 15 wt. % cleansing surfactant,
c) water, and
d) protonating agent, wherein:, the cleansing surfactant comprises from 85 to 100% by weight of a combination of betaine surfactant and taurate surfactant, and wherein:, when the composition comprises 5 to 6 weight percent of cleansing surfactant, the weight ratio of betaine surfactant to taurate surfactant is from 55:45 to 45:55;, when composition comprises from greater than 6 weight percent to up to 10 weight percent of cleansing surfactant, the weight ratio of betaine surfactant to taurate surfactant is from 80:20: to 40:60; and, when the composition comprises greater than 10 weight percent of cleansing surfactant, the weight ratio of betaine surfactant to taurate surfactant is from 80:20: to 20:80;, wherein the composition is essentially free of sulfate surfactant.
