The Saponin was extracted from Rice Husk through various steps of procedure:Extraction with Ethanol, Re-extraction, Separation of Aqeous and Organic Phase, Evaporation, Drying and Weight Determination: The Weight of Obtained Saponin was 1730 mg and % yield of Saponin was 86.50 %. Characterization of Physical Property was done by Determination of Surface Tension and CMC by using various analytical techniques i.e. Stalagmometer, Conductivitymeter, Absorbance by Spectrophotometer. The CMC of Saponin was found 0.04 gm/L and surface tension was 59.29 mN/m. The CMC of SLS was found 8.0 mM and surface tension was 32.55 mN/m. The Study of Anionic-nonionic mixed surfactant system: In present investigation, the interaction between sodium Lauryl Sulphate (SLS) as an anionic surfactant and Saponin as a nonionic surfactant is studied. Saponin is capable to reduce CMC of ( Anionic Surfactant-SLS) and as a result CMC of mixed Surfactant systems were also reduced up to 0.6 mM. As the ratio of Saponin is increasing in the mixed Surfactant systems, the CMC of mixed micelles are found reducing: The CMC of mix Surfactant 1:9 (Saponin + SLS) Solution is found 1.5 (mM). The CMC of mix Surfactant 3:7 (Saponin + SLS) Solution is found 0.9 (mM). The CMC of mix Surfactant 5:5 (Saponin + SLS) Solution is found 0.6 (mM).
