Nipagin esters were synthesized by the esterification of dodecyl and octadecyl alcohol with p -hydroxybenzoic acid in the presence of vitamin C.

Then-octyl gallate was prepared by esterification of alcohol and gallic acid in catalysis system of dodecyl benzene sulfonic acid.

And the results were anhydrous sodium sulfite 0.2%, sodium lauryl sulfate 7%, fatty alcohol polyoxyethylene lauryl ether sulfate sodium 12% and dodecyl betaine 4%.
