SCIENTIFIC SESSIONS – MONDAY
3:30 pm – 5:00 pm
Hot Topics in Cosmetics and Color Additives
An increasingly global marketplace has resulted in
many novel and complex challenges for the analysis
of ingredients and contaminants (chemical and
microbiological), and the analysis of color additives in
foods and cosmetics. Consumers are as concerned
about the chemical composition and safety of cosmetic
products as they are about foods, both of which may be
imported from a variety of countries as well as domestically
produced. This has heightened interest in the alignment
of regulatory requirements for the marketing of cosmetics
and the international harmonization of scientific methods
and standards. This AOAC Scientific Session provides
initial briefings that speak to the challenges on both
the regulatory and analytical scientific fronts, including
the harmonization of analytical methods. This session
is intended to further develop our AOAC Community on
Cosmetics and Color additives.

Rapid Methods for Chemical Contamination:
Cell Based assay, Spectroscopy, Portable
Devices and Beyond
Chemical contaminants such as mycotoxins and dioxins
pose a major risk for human and animal health. Regulatory
limits are established globally to reduce human and animal
exposures to chemical hazards. Rapid assays for chemical
contaminants play an indispensable role in regulatory frame
work with regard to surveillance and compliance. Compared
to classical chromatography or mass spectrometry based
platforms, a variety of screening methods are less costly
and present much higher throughput, which facilitates
analyzing a large volume of samples in a rapid and eco-
nomic fashion. Other advantages of rapid methods include
enablement of on-site decision making by point-of-sampling
tests. The strengths and weaknesses of the rapid methods
will be elaborated and performance standards will be dis-
cussed in the first presentation. In the second presentation,
a non-main stream cell based assay for analyzing dioxin,
a group of persistent environmental pollutants and highly
toxic chemicals even at trace level concentrations (ppt) will
be introduced. The classical assay for dioxins is the high
resolution gas chromatography and mass spectrometry
analysis, which is tedious and time consuming. CALAUX, a
cell based bio assay has been developed and validated to
screen dioxin at trace level concentrations. Furthermore, a
field portable X-RAY fluorescence based platform will be
presented for analyzing mercury in face cream products
and providing reasonable agreeable results with the ICPMS
analysis results. Finally, the feasibility of using a surface-
enhanced Ramen spectroscopy based method to screen
aflatoxin in maize from 0 to 1000 ug/kg concentration range
will be presented. The session will offer audiences a broad
spectrum of some non-mainstream rapid chemical screen-
ing assays and their potential applications.
