PP food storage containers and LDPE bags with Silver Nanoparticles
Information given by producer:
‘FresherLonger containers are infused with silver
nanoparticles because silver in microscopic particle
form is a safe, medically proven antibacterial agent
that fights the growth of mold and fungus. In tests
comparing
FresherLonger
to
conventional
containers the 24‐hour growth of bacteria inside
containers,
FresherLonger containers was reduced by over 98
percent. ‘

Production process usually involves sandwiching of the layer of nanoclay
in between two layers of polymer, so the nanoclay itself does not have
contact with food product directly.

Nano‐encapsulated CoQ‐10
Information given by distributor:
‘Fat
Fat‐soluble
soluble nutrients are essential to health but are not very
bioavailable. That is because in order to be absorbed, they
must first be converted in the body to a water‐soluble form.
Unfortunately, this "pre‐processing" is imperfect, causing a
significant — and sometimes near‐total — loss of active
ingredient.
A Solgar first, Nutri‐Nano is a patent‐protected
nanotechnology that transforms fat‐soluble nutrients into
water‐soluble ones — significantly increasing absorption.
How? Through surrounding the fat‐soluble molecules with a
water‐soluble shell called a micelle, which is only 30
nanometers in diameter.
diameter (A nanometer is one‐billionth
one billionth of a
meter). The micelles carry the fat‐soluble nutrient directly to
the absorption site, where it is released and absorbed.’

‘Argentum plus/ Colloidal Silver 10 ppm was first developed
by Living Energy Systems in the 1990’s to be absorbed
straight into the blood stream when held under the tongue
for 30 seconds or into the epidermis when applied topically.
Its silver concentration of 10 ppm (parts per million) is
comparatively low, but the very small silver particle size of
0.001‐0.002 micron means that in a dose of 5 ml there are
more than 200 thousand elemental silver particles present,
which are on average made up from 12‐16 ionized silver
atoms each, thus creating a very potent silver effect.’
