The objective of this study was to determine the influence nonionic surfactants on effectiveness preservatives used in emulsions containing high surfactant content. Mixtures different concentrations were prepared between polyethoxylated (40) hydrogenated castor oil (PHCO) and polyoxyethylene sorbitan monooleate (PSO), with methylparaben, phenoxyethanol, ethylparaben, propylparaben, isobutylpara...

A chemical study on the n-BuOH-soluble fraction of the 95% EtOH extract of red yeast rice fermented with the fungus Monascus pilosus BCRC 38093 (Eurotiaceae) has resulted in the isolation of one new natural pyrrole derivative, designated as monascuspyrrole (1) together with nine known compounds, 3β-hydroxystigmast-5-en-7-one (2), β-sitostenone (3), monascin (4), ankaflavin (5), N-trans-feruloyl...
