Esempi
I have done a bit of homespun research of my own into this group of compounds, of which there are five: butyl, ethyl, isobutyl, methyl and propyl paraben .
Twenty breast tumours have been found to contain high concentrations of paraben , a chemical that mimics estrogen in the body.
The family's common names follow the standard alkane hydrocarbon sequence: methyl paraben, ethyl paraben, propyl paraben, butyl paraben , etc.
