AFTER A LENGTHY recession marked by job cuts and reduced R&D budgets, the mood was definitely
upbeat at last month’s annual meeting of
the Society of Cosmetic Chemists (SCC).
The meeting was held in New York City,
Dec. 9-10, and attracted nearly 1,200 industry executives—which represented an
increase over 2009 attendance, according to
the Society. Attendees heard presentations
on a variety of subjects, including hair
styling, sun protection and genomics. Yash
Kamath received the SCC’s highest honor,
the Maison G. deNavarre Medal, during
the awards luncheon (see p. 93).
The annual meeting got underway with
opening remarks by chairman Robert Y.
Lochhead of the University of Southern
Mississippi. Randy Wickett of the University of Cincinnati succeeded Lochhead as
“We have great attendance,” observed
Lochhead.“It shows that we are doing well
even in recession.”
The Dec. 9 morning session was de-
voted to sunscreen, and was moderated by
Howard Epstein of EMD Chemicals. He
noted that non-government organizations
(NGOs) are raising questions about sun-
screens that must be addressed.
Johann Wiechers did just that with a
presentation on the skin penetration of
nanoparticles from sunscreen formulas. According to Wiechers, the number of sunscreen products containing nanoparticles

has risen from 54 in 2005 to more than
1,000 in 2010.
“There is no epidemiological evidence
of risk,” he told the audience, and he urged
the industry to inform the consumer and
not hide from NGOs that disparage the science and the industry. According to Wiechers, nanoparticles do penetrate into the
stratum corneum, but do not penetrate into
the viable layers of the epidermis.
Wiechers noted that when nanoparti-
cle size is smaller than 10nm, the material
can penetrate the SC. However, the indus-
try uses particles ranging in size from 10-
60nm. In addition, titanium dioxide and
zinc oxide often agglomerate to form larger
particles. Moreover, these particles have an
anionic coating that does not favor skin
penetration. With this information in hand,
cosmetic chemists should be confident
about incorporating nanoparticles in their
sunscreen formulas, he told the audience.
