Hi,
As we all know sun cancer is a problem that concern all of us and we
look for "proteccion" as recommended by the people that know about
this subject.
We believe on them an carry on sailing.
Cheers

The other day selecting a sun barrier cream I notice that there are
two types: one without chemical absorvents and the other (the most
popular)without comments about "absorvents"
After done same research on the Net I come with the attached *.doc
Please read it and Drs. in the group explain to us about it. Looks to
me that it is not "plain sailing"04 Oct 00 - Food Safety -
Sunscreens 'may be toxic'
BBC
BBC News ... Wednesday 4 October 2000
A chemical used in most sunscreens to protect against skin cancer
could damage human cells , according to a study.
Research carried out in Norway found that octyl methoxycinnamate
(OMC), which is used in 90% of sun creams to protect against ultra
violet rays, could be harmful if it seeps into a person's blood
stream.
The scientists based their findings on tests they carried out on mice.
They added small concentrations of the chemical to an ethyl alcohol
solution containing mouse cells.
They found that while over 90% of the cells survived when put in this
solution, half were killed when the OMC was added.
They then place the solution under a lamp for two hours to simulate
the effects of the chemical in sunshine.
Under these conditions, the chemical was found to kill even more
mouse cells.
The scientists, from the Norwegian Radiation Protection Authority,
suggest that this is because the chemical becomes twice as toxic when
it comes into contact with light.
They add that the chemical could damage human cells if it penetrates
the skin and warn the public only to use sunscreens that contain OMC
when they have no other choice.
But the findings of the study have been dismissed by the Cosmetic
Toiletry & Perfumery Association, which represents sunscreen
manufacturers in Britain.
OMC has been approved for use as a sunscreen for many years and has
been thoroughly tested for safety said a spokeswoman for the Cosmetic
Toiletry & Perfumery Association, the findings could not be applied
to people who use sunscreens normally.
She added that the chemical had been "thoroughly tested" and was
approved by authorities in the UK and US.
"OMC is approved and listed in the Cosmetics Directive and is also
approved in the Food and Drugs Administration Sunscreen Monograph in
the USA as a safe and effective sunscreen.
"OMC has been approved for use as a sunscreen for many years and has
been thoroughly tested for safety."
Advice Dr Charlotte Proby, a consultant dermatologist with the
Imperial Cancer Research Fund said: "It is difficult to extrapolate
from laboratory experiments in mice to humans out in the sun.
"Undoubtedly the best advice is to avoid the sun and cover up with
clothing, and wear a hat and sun-glasses.
"However, using sunscreens to prevent sun damage to cells is likely
to reduce the risk of skin cancer development, and is far better than
not using any sun protection at all."
