“Analytical
Techniques to Ensure the Performance and Quality of
Encapsulates”
Abstract:
Fragrance
ingredients are used in a wide variety of household and
personal care products. However, it is often the case that
hedonically important fragrance molecules are incompatible
with various bases, are not substantive, or would be more
impactful if they could be released at specific points of
product use. This can be achieved through development of a
more complex fragrance system that contains encapsulated
fragrance ingredients.
The ability to
create successful fragrance capsule systems and products
requires a tremendous amount of analytical support to ensure
quality, monitor stability and confirm performance. This
presentation will address the development of
chromatography-based methods that we have employed to
evaluate fragrance capsule systems, how our lab has
incorporated automation to handle large volumes of samples
for these various methods and how chromatography data fits
in to creation of successful capsule-containing products.
Biography
Danielle DiNallo
is currently a Research Investigator at International
Flavors & Fragrances Inc., located in Union Beach, NJ. In
the 10 years that she has worked at IFF she has focused on
trace chromatography techniques for the study of a variety
of commercial systems including contaminants in raw
materials, detection of heteroatom containing constituents
and headspace-based sampling methods. Many of these
headspace methods have been applied to capture volatile
materials from products and other systems to establish a
correlation with olfactive data. Danielle has also worked
extensively on developing a highly automated approach to
determine the fate of polymerization byproducts using
integrated preparation/analysis systems.
Danielle
obtained a BS degree in chemistry from The College of New
Jersey and a MS degree in chemistry from Seton Hall
University. Her graduate research was in drug and steroid
analysis by SPME on-fiber derivitization with GC/MS.
