Condition of producing synergetic effect for mixed emulsifier of sodium dodecyl sulfate and sulfonated castor oil

Sodium dodecyl sulfate(SDS)and sulfonated castor oil can be mixed to emnlsify chlorinated polypropylene(CPP)and its graft copolymer with maleic anhydride for preparating environmental friendly waterborne adhesives and coatings,So the study of synergetic effect of duplicate mixed emulsifier of sodium dodecyl sulfate and sulfonated castor oil is very valuble theoretically.Furthermore,sodium dodecyl sulfate and sulfonated castor oil belong to anionic surfactants,the study on synergetic effect of anionic surfactant and anionic surfactant is very much few.By measuring surface tension of sodium dodecyl sulfate and sulfonated castor oil in water by usingJK99C surface tensiometer,the condition of producing, synergetic effect for them was made sure.
