| 1. A personal cleansing composition comprising:
A. from about 5% to about 50% by weight of a detersive surfactant component selected from the group consisting of anionic
surfactants, amphoteric and zwitterionic surfactants having an attached group that is anionic at the pH of the composition,
and combinations thereof;
B. from about 0.025% to about 5% by weight of a water soluble or dispersible, cationic, non-crosslinked, conditioning polymer
mixture comprising:
(a) a copolymer comprising:
ii. one or more cationic monomer units selected from the group consisting of diallyldimethyl ammonium chloride and 1-Propanaminium,
N,N,N-trimethyl-3-[(2-methyl-1-oxo-2-propenyl)amino]-, chloride, and
iii. one or more nonionic; the nonionic units being selected from the group consisting of vinyl nitriles, vinylamine amides,
vinyl alcohol, vinyl pyrolidone, vinyl aromatic compounds, styrene, acrylonitrile, methylacrylate, ethylacrylate, n-propylacrylate,
n-butylacrylate, methylmethacrylate, ethylmethacrylate, n-propylmethacrylate, n-butylmethacrylate, 2-ethyl-hexyl acrylate,
2-ethyl-hexyl methacrylate, 2-hydroxyethylacrylate and 2-hydroxyethylmethacrylate;
wherein said copolymer has a positive charge, a cationic charge density of from about 2 meq/gm to about 10 meq/gm, and an
average molecular weight of from 100,000 to 2,000,000; and
(b) a homopolymer having a cationic charge density of from about 5 meq/gm to about 10 meq/gm, the homopolymer being selected
from the group consisting of: diallyldimethyl ammonium chloride and 1-Propanaminium, N,N,N-trimethyl-3-[(2-methyl-1-oxo-2-propenyl)amino]-,
chloride; and
C. from about 20% to about 94% by weight of water;
wherein said composition comprises lyotropic liquid crystals.
