NANOTECHNOLOGY
IN
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derivatives in which one fatty acid has been
replaced by a phosphate group and one of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.

Microparticle – has a dimension of 200
nanometers

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.

• L’Oreal launched the
first nano-based
product in 1997.

• Nanoscale titanium
dioxide and zinc oxide
has a whitening effect
by leveraging photonic
effects to improve the
appearance of skin

• Lancome Renergie
Morpholift eye cream
• Lancome Soleil Instant

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

• Nanoscale ingredients
help lipstick to last
longer, smear less,
reflect light, and glow in
vibrant colors
• Nanoscale ingredients
help foundations and
powders to have a
smoother finish and are
much lighter and
translucent
M.A.C. PRODUCTS
• Plushglass lip gloss and
volumizer uses
nanosomes to deliver
phospholipids. It is a
super moisturizing
formula

DEODORANT

• Roll-on deodorant uses
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

o-1.html
SUNSCREEN
• Uses a nanoscale
amount of zinc oxide
and titanium dioxide to
provide the best
protection for your skin
from the sun; also
referred to as a
microparticle
http://shop.cancercouncil.com.au/store/c-75-sunscreen.aspx
TOOTHPASTE
• There are several
toothpastes on the
market that decrease
teeth sensitivity by
utilizing nanoparticles
of hydroxyapatite

HENKEL’S TOOTHPASTE/NANIT
ACTIVE
http://www.magicessence.com.au/neem-activetoothpaste
• 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.
HAIR DRYERS
• MEMS thermopiles
monitor the hair’s
temperature while
drying and help to
automatically regulate
the heat output to
reduce damage to the
hair

NANO-CERAMIC PRODUCTS
http://www.britannica.com/EBchecked/topicart/251916/138779/Hairdresser-using-a-curling-iron
• Nano-ceramic products
use ultra-smooth
technology that reduces
friction, which results in
the surface of curling
irons and flat irons less
likely to catch and break
hair and prevent
corrosion on the
product
SHAVERS
• Norelco Cool Skin shaver
uses the Nanoflex stainless
steel strip in the stationary
cutter head, rotating cutter
knife, and hair lifter
resulting in being corrosionresistant, strong and
formable
• Some shavers have small
OLED displays to illustrate
the battery’s remaining life
