Decyl Glucoside Synthesized by Direct Glucosidation of D-Glucose Over Zeolite Catalysts and Its Estrogenicity as Non-Endocrine Disruptive Surfactant

The estrogenicity of decyl glucoside was asserted as a non-endocrine disruptive surfactant with its preparation method using zeolite catalysts. Its estrogenicity was estimated using E-assay method. The decyl glucoside was synthesized by direct glucosidation from D-glucose with 1-decanol. The conversion and yield were improved with increasing of amount of acid sites of the zeolite catalysts. The decyl glucopyranoside is more hydrophilic than nonylphenol and has a high wettability. The decyl glucopyranosides exhibited extremely lower proliferation of estrogenic cell compared with nonylphenol.

Estrogenicity of Octyl Glucoside Synthesized by Direct Glucosidation as Non-Endocrine Disruptive Surfactant

The estrogenicity of octyl glucoside was studied with its preparation method using microporous zeolites. Its estrogenicity was estimated using E-assay method to confirm the possibility as non-endocrine disruptive surfactant. The octyl glucoside was synthesized from D-glucose with 1-octanol by direct glucosidation. The high conversion of D-glucose was obtained on H-FAU zeolite which has a mild acid strength. The conversion and yield were improved with increasing of acid site amount of the zeolite catalysts. The octyl glucopyranoside is more hydrophilic than nonylphenol and has a high wettability. The octyl glucosides represented extremely lower estrogenic cell proliferation compared with nonylphenol.
