Scientists at the USDA Agriculture Lab in Peoria may have discovered a way to protect skin from
sun damage without harming the environment. The Great Lakes Radio Consortium’s Tanya
Koonce reports the new mixture has a soy bean or vegetable oil base:
Right now most sunscreens are made from a cream or petroleum base that doesn’t break down in
the water. Two scientists at the Ag Lab in Peoria think they may have a way to remedy that by
using soybean oil and another plant based product called ferulic acid. Joe Lazslo is the lead
scientist who came up with the idea.
“The ferulic acid is present in plants. And if plants were worried about getting sunburned they
already have their sunscreen present. We’re just taking it out of plants and putting it into
soybean oil so that it can then be incorporated into cosmetics or other suntan lotions, that type of
thing.”
Laszlo and his colleague Dave Compton are standing in the lab next to a bottle of Kroger brand
vegetable oil. They use the same soybean oil in the lab you’d buy at the store. Lazslo says it gets
the job done. He says they’ve been working on their so-called soy screen mixture for
more than a year:
“There are many aspects or uses of the process that we are doing right now that are very
environmentally sound. We don’t pollute with this process. All the starting materials and
products are very environmentally benign. That means Soy Screen itself does not accumulate in the
environment. It’s biodegradable. All these types of things.”
Lazslo says most importantly Soy Screen doesn’t build up in the water supply. But because it’s
just barely out of the lab, doctors and other scientists are not willing to weigh in on its pros or cons
for human use. Specifically they are quiet on the dermatological effects – like whether the
vegetable oil-based product clogs skin pores.
But Lazslo says other scientists have found anti-oxidants like ferulic acid prevent wrinkling and protect against the sun’s rays that are known to cause
skin cancer. He says before Soy Screen makes its way into face lotions and other consumer
products licensing companies will have to confirm these claims.
While doctors aren’t ready to sing the praises of Soy Screen, soybean growers are. In the best
case scenario, Soy Screen would require about a million pounds of soybean oil each year. That
just barely scratches the surface
of the 800 million pound annual surplus. But the Soybean Growers Association’s Theresa Miller
says it does have an impact on public perception.
“We always are looking for any new use that might develop. You know as much as anything, of
course getting a product like a soy sunscreen or soy crayons or some of these uses that maybe don’t
mean a lot in terms of bushels, they do mean a lot in terms of public relations. In terms of getting
the word soy out in front of consumers and making them more aware of what all those soybeans out in
the field get used for.”
Soy Screen is likely years away from receiving the FDA’s blessing, despite the perks it may offer
the environment and soybean growers. Co-developer Dave Compton says it takes several years
and several million dollars for the FDA to approve something as a sun block:
“Currently the FDA regulates these active ingredients as “category one” drugs. So you have to have
FDA approval to claim an SPF. So before you will see a packaged retail item with the word Soy
Screen and an SPF we would have to go through an FDA approval of the Soy Screen.”
Compton says in the meantime Soy Screen will likely work its way into cosmetic products that
claim anti-aging effects. He says the money earned from its use in those anti-aging cosmetics will
help defray the cost of the FDA approval process. For the Great Lakes Radio Consortium, I’m
