PERSONAL CARE

KEY TERMS


MEMS


three dimensional objects that perform a
mechanical function, whose dimensions are between
1 to 100 micrometers


Nanoparticle


a particle of material at the nanoscale


Nanotechnology


a material or structure
purposefully manufactured with dimensions
between 1 and 100 nanometers to leverage the
unique properties it has at that size


Nanodispersion


the even distribution of nanoscale
ingredients in a liquid, gel, or powder



Nanoemulsion


two ingredients that don’t mix well;
particles around 50 nanometers in diameter



Nanoencapsulated


creating an outer layer on
another material




Nanosphere


a round particle with nanoscale
proportions



Nanosomes


microscopic lipospheres that deliver
active ingredients deeper into tissues. Much smaller
than human skin cells, they encapsulate compounds
within microspheres of material similar to skin to
reach deeper than standard carriers and boost the
effectiveness of active ingredients.

Hydroxyapatite


a calcium found in the dentin which
forms a protective barrier on teeth



OLED


An
organic light emitting diode

(
OLED
) is a
light
-
emitting diode

(LED) in which the
emissive

electroluminescent

layer is a film of
organic
compounds

which emit light in response to an
electric current. This layer of
organic semiconductor

material is situated between two electrodes

http://en.wikipedia.org/wiki/Oled



Phospholipids


Phospholipids are
fat

derivatives in which one fatty acid has been
replaced by a
phosphate group

and one of
several nitrogen
-
containing molecules.

WHY NANOTECHNOLOGY?


Using ingredients at the nanoscale allows
personal care products to penetrate deeper
into the skin to visibly improve its appearance


The whole point behind cosmetics is the
targeted delivery of vitamins, botanicals, and
other active ingredients into the skin. The
smaller their size, the better they’re able to
penetrate the skin’s outer layer in order to
moisturize and soften wrinkles.


CONTROVERSY WITH NANO IN PERSONAL
CARE PRODUCTS


How deeply can nanoparticles penetrate the
skin, whether they can enter the bloodstream,
and it so, then what?


Some believe using nanoparticles crosses the
line in terms of function


Others are concerned about whether the use
of nanoparticles is harmful


Nanoscale ingredients can
penetrate the upper layers
of the skin, which improves
the appearance of skin by
making it plumper and
more youthful looking.


Nanotechnology makes it
possible to use some
ingredients by
encapsulating them that
would otherwise cause
irritation on their own.


Most personal care
products leveraging
nanotechnology are
more widely available in
Europe and Asia. It
appears that they are
more open to using new
technology.

COLOR COSMETICS


Nanotechnology is used
in color cosmetics to
deliver ingredients
deeper into the skin to
hydrate and improve
skin texture and to
make sunblock
transparent

DEODORANT


Roll

nanoemulsion that results
in no white residue


Some spray deodorants
have a nearly gasless
approach that is more
concentrated which results
in a smaller can that lasts as
long or longer as a large can

HAIR CARE


Haircare products
benefit from
nanoparticles because
they are able to
penetrate the hair
shaft, rather than
simply coating it

market that decrease
teeth sensitivity by
utilizing nanoparticles

HENKEL’S TOOTHPASTE/NANIT
ACTIVE


Consists of nanomaterials,
in conjunction with the
saliva in the mouth,
encourage the formation of
a thin protective layer on
the teeth; the tooth
remineralizes itself, and as a
result tooth sensitivity is
reduced.

Nanotechnology is a young and growing field


An estimated two million skilled nanotechnology
workers will be needed worldwide by the year
2015


one million of them in the U.S.


Graduates are receiving salary offers up to
$55,000 per year with a two
-
year degree


Graduates with a baccalaureate degree can
expect salary offers up to $65,000 per year


Students who choose to continue their education
