ParabensUpdated a month ago

A family of preservatives used in food, pharmaceuticals, and beauty products. They include Benzylparaben, Butylparaben, Ethylparaben, Isobutylparaben, Isopropylparaben, Methylparaben, and Propylparaben. There is some evidence that parabens can accumulate in human breast tissue. Clinical studies on animals have indicated that parabens may mimic estrogen and act as a potential hormone (endocrine) system disruptor.

Benzylparaben: is a broad-spectrum preservative. There is evidence that it can trigger growth responses in estrogen-sensitive breast cancer cells. The injections of benzylparaben were also shown to increase the weight of the uterus in mice, which indicates it may be hormone-disrupting.

Butylparaben: may mimic estrogen and act as a potential hormone (endocrine) system disruptor. It has also been reported to have adverse effects on the male reproductive system in animal studies.
