     "Purity" referrs to the "dispersity" of the detergent preparation. "P" indicates heterogeneity or polydispersity in molecular form, while "M" indicates homogeneity or monodispersity.

  §   CMC referrs to the Critical Micellar Concentration, or that total concentration of detergent that corresponds to the maximum possible concentration of detergent monomer in solution. The CMC is very sensitive to temperature and polarity of the medium. The CMC is generally given at 20-25º C, unless indicated otherwise in the table.
