Fifteen kinds of anionic surfactants were prepared by addition of sodium hydrogen sulfite with Diels-Alder adducts which are obtained via diene synthesis of alkyl-isobornyl-maleate (alkyl; ethyl, n-butyl, 2-ethyl-hexyl) and diene such as 1, 3-butadiene, isoprene, cyclopentadiene, 1, 3-p-mentha-diene and alloocimene. Thirty kinds of nonionic surfactants were prepared by addition of polyethylene glycol whose molecular weight being 400 and 600, with these Diels-Alder adducts. Thus synthesized surfactants were investigated for the surface activities such as for surface tention, foaming property, penetrating power, solubilizing power, solubilizing power and for emulsifying power. In these anionic surfactants, the surface activities of sodium sulfonate of adducts of alkyl-isobornyl-maleate and alloocimene were excellent as compared with Aerosol OT (sodium di-2-ethyl-hexyl-sulfosuccinate) and ABS (sodium dodecyl-benzene sulfonate). In the nonionic surfactants, some kinds of the surfactants showed almost similar surface activities as compared with LAS (sodium linear alkyl benzenesulfonate) and di-2-ethyl-hexyl-succinyl-polyoxyethylene ether.
