Pursuing better release and retention of F&F materials
n RACHEL GRABENHOFER, Managing Editor, Cosmetics & Toiletries
If you’ve ever endured a long commute to work, you’ve likely had that lucid moment wondering, “Isn’t there a better way?” I have good news for you: there is. Teleportation and time travel are already possible and in our
future—at least, if you believe Andrew Basiago, a
Vancouver, Washington, USA-based attorney.
Basagio’s been speaking very publicly, and convincingly, about his participation as a child in secret
government tests to teleport through time. He knows
how this sounds, and was of course given a “gag
order” to not divulge this information, which is why
he says he went public; to protect himself.
Whether you believe Basiago or not, pausing to
consider the technology may, in fact, exist brings
hope; and if it does exist, it’s because someone didn’t
give up trying.
This parallels the struggle F&F developers face,
to keep trying new ways to improve the delivery
and duration of flavors and fragrances for consumers. These trials are the focus of the current review;
there’s not teleporting or time travel in here, but
that’s not to say they never will be.
A study in the Journal of Food Processing inves-
tigated the characteristics, release behavior and
antioxidant activity of clove essential oil-hydroxy-
propyl beta-cyclodextrin (CEO-HPbCD) inclusion
complexes. Here, the clove oil was encapsulated by
the kneading method with HPbCD in a 1: 1 ratio.
The in vitro release profile indicated slow and
sustained release. DPPH-scavenging activity of free
clove essential oil and encapsulated particles was
25.20% ± 1.02 and 28.70% ± 0.77, respectively. The
total phenolic content of free clove essential oil
was 18. 59 ± 1. 60 mg GAE/100 mg oil, while total
phenolic content of particles was 22. 57± 1. 48 mg
GAE/100 mg oil. These results revealed that using
HPbCD to encapsulate clove essential oil could
benefit food and pharmaceutical applications. 1
According to work presented in Cellulose, the way
essential oils and plant extracts in micro- or nano-sized capsules are applied to fabric can affect its
properties. This is primarily due to evaporation. These
authors compared the simultaneous in situ encapsulation/stabilization of essential oils applied to cotton
fabric with a process of UV-curing nanocapsules.
FT-IR and UV-vis analysis confirmed the presence of
encapsulated peppermint oil on the cotton fabric.
Longer controlled release and increased fabric
stiffness were observed in the case of UV curing,
