and a few other alphabet stews common to chemical sunscreen have also been found to be toxic to coral.
The site lists other chemicals that can be harmful to corals: octinoxate (octyl methoxycinnamate), homosalate, octocrylene
, avobenzone, octisalate, homosalate, fragrances and nano-particles ("clear"; TiO2; ZnO).
The innovative lotion described in this article filters out UVA by combining zinc oxide and titanium dioxide, while the spray version blocks UVA with a combination of avobenzone and octocrylene
Key ingredients include avobenzone, homosalate, octisalate, and octocrylene
The ones identified in filters drinking water are benzophenone-3 (BP3), octocrylene
(OC), 2-ethylhexyl 4-methoxycinnamate (EHMC), 3-(4-methylbenzylidene) camphor (4-MBC), and 2-ethylhexyl 4-(dimethylamino) benzoate (OD-PABA).
If your skin is sensitive, zinc oxide or titanium dioxide are natural minerals with stellar UVA coverage; otherwise, you may want the longer-lasting protection of chemical-based SPF with UVA-blocking avobenzone or octocrylene
The polyurethane dispersion can significantly increase the SPF in formulations containing Octocrylene
, Ethylhexyl Triazone (both UV-B filters), bis-Ethylhexyloxyphenol Methoxyphenyl triazine (BEMT) or Benzophenone 3 (broad band UV filters), although the dispersion itself does not contain any UV-absorbing groups.
In 2005 a series of experiments using sunscreen containing octocrylene
, octylmethoxycinnamate and benzo-phenone-3 revealed that within one hour of application according to manufacturer's instructions, the chemicals were generating more "reactive oxygen species"(ROS) in the skin than people wearing no sunscreen were getting via direct UV radiation.
Redermic [U], on the other hand, contains neurosensine, a calming ingredient to neutralize micro inflammation of nerve endings in the skin, as well as a patented combination of octocrylene
with avobenzone and octisalate to provide broad-spectrum sun protection.
This product line features the Cell-Ox Shield: a combination of two sun filters, avobenzone (3%) and octocrylene
(5%), plus an antioxidant complex to protect skin from environmental damage and a photostabilizing booster for longer-lasting sun protection.
(used with avobenzone helps to improve overall stability)
The sunscreen also includes two well-known but relatively unstable UVA organic absorbers, octocrylene
and avobenzone (Parsol 1789).
