Development of anionic surfactant compound  is very important because the anionic surfactant class  is widely used in people's lives.  For instance, anionic  surfactants are used  as food additives and detergents.  T he  novel compound  of sulfonate -based surfactant or proposed compound  ha s predicted the C ritic al M icelle  C oncentration (CMC) value of experiment . Quantitative Stru cture-Property Relationship (QSPR) analysis based  on  semiempiri cal ZINDO/1  calculation was conducted to obtain QSPR equation.  Theoretical p redictors or independent variable which have  an influence on the value of  CMC  are used to construct QSPR equation . The theoretical predictors are classified  into predictor of electronic properties, solubility and steric. A total of 108 experimental CMC belongs to  sulfonate -based surfactant  are calculated their theoretical  predictor s and  analyzed by multiple linear regression.  The  QSPR equation which is obtained from this study  contains the important  theoretical  predictors . They are  solubility properties, molecular weight, molecular size and  net  charge  of  carbon atom in the polar part of sulfonate-based surfactant .  This  QSPR equation c ould be used to predict the  CMC  value of the  novel sulfonate-based  surfactant .
