A study from the Hebrew University of Jerusalem, found that sperm counts among western men have more than halved in 40 years – and the reasons are unclear. Now a research in Poland found that men using parabens in grooming products were more likely to have abnormally-shaped sperm and sperm that does not move as well as it should.
They tested the preservatives butylparaben, ethylparaben, isobutylparaben, methylparaben and propylparaben, which has been used in the past in cosmetic products. They also found out that butylparabene was also linked to greater chances of DNA damage in the sperm.
In regulation (EU) 1004/2014 from 18. September 2014 the concentration of butylparabene and propylparabene is limited to 0,19 % total amount of bouth parabenes. Isopropyparabene is prohibited and the limits of ethylparabene and methylparabene are not changed.
But anyway butylparabene and propylparabene are further potential risk in meaning of the commission.
