USDA Agency Grants License on Soy-Based
Sunscreen By Jan

SoyScreen, a biodegradable sunscreen derived from soybean oil, could
be a step closer to becoming a commercial product for health-conscious
On October 3rd, the Agricultural Research Service (ARS) granted an exclusive license on the
patented sunscreen technology (US no. 6,346,236) to iSOY Technology Corporation
of Cary, Illinois. The license stems from a cooperative research and
development agreement (CRADA) in which iSOY is working with ARS chemists
Compton to scale up production of SoyScreen, as well as create variations
of it having different properties.
They developed SoyScreen at the ARS
Center for Agricultural Utilization Research in Peoria, Ill., where 100
full-time scientists explore innovative new ways to create value-added products
from U.S. crops, particularly corn and soybeans.
In SoyScreen, they envision a skin- and hair-care product that could
expand the market for U.S. soy oil. Of the 17.6 billion pounds consumed
domestically, 628 million pounds of soy oil is used for industrial purposes,
according to the American Soybean
SoyScreen owes its sunburn-preventing properties to ferulic acid, an
antioxidant in rice, oats and other plants. To keep the antioxidant from
dissolving in water, the Peoria researchers chemically bound it to soy oil
using lipase enzymes and heat in an environmentally friendly process called
biocatalysis. The resulting lotion won't wash off from swimming or sweat, and
is non-polluting, according to Laszlo, in the ARS center's
and Processing Technology Research Unit.
In sun-protection-factor tests there, SoyScreen filtered out harmful
ultraviolet light as well as four chemical UV absorbers: oxybenzone,
dioxybenzone, octyl methoxycinnamate and padimate-O.
ARS patented the technology in February 2002 on behalf of the U.S.
Department of Agriculture (USDA). iSOY is
collaborating with Laszlo and Compton under a CRADA with ARS and the
Biotechnology Research and
Development Corporation, which helps finance commercial-sector development
of new lab-bench technologies. iSOY anticipates initial markets in skin-, hair-
and related personal-care products.
ARS is the USDA's chief scientific research agency.
