Safety Studies
One study performed in 2000 raised safety concerns about octyl methoxycinnamate by demonstrating toxicity to mouse cells at concentrations lower than typical levels in sunscreens. However, a more recent study concluded that octyl methoxycinnamate and other sun screening agents do not penetrate the outer skin in sufficient concentration to cause any significant toxicity to the underlying human keratinocytes. Estrogenic effects were noted in laboratory animals at concentrations close to those experienced by sunscreen users and were also shown in test tube experiments. A study published in 2011 explored the effects of pre- and post-natal exposure to high doses of octyl methoxycinnamate in rats and showed, for example, that the testes weight and testosterone levels were significantly reduced in male rats.

Famous quotes containing the words safety and/or studies:
“There was only one catch and that was Catch-22, which specified that a concern for one’s own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to.”
—Joseph Heller (b. 1923)
“Even if one studies to an old age, one will never finish learning.”
—Chinese proverb.
