1 NANOTECHNOLOGY IN PERSONAL CARE

2 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

3 Nanodispersion – the even distribution of nanoscale ingredients in a liquid, gel, or powder Nanoemulsion – two ingredients that dont mix well; particles around 50 nanometers in diameter Nanoencapsulated – creating an outer layer on another material

4 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.

5 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 light-emitting diodeemissive electroluminescentorganic compoundsorganic semiconductor

6 Phospholipids – Phospholipids are fat derivatives in which one fatty acid has been replaced by a phosphate group and one of several nitrogen-containing molecules.fatphosphate group Microparticle – has a dimension of 200 nanometers

11 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 theyre able to penetrate the skins outer layer in order to moisturize and soften wrinkles.

12 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

13 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.

14 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. a-map.html

21 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 orant.jpg

22 HAIR CARE Haircare products benefit from nanoparticles because they are able to penetrate the hair shaft, rather than simply coating it o-1.html

23 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

24 TOOTHPASTE There are several toothpastes on the market that decrease teeth sensitivity by utilizing nanoparticles of hydroxyapatite toothpaste/dentifrice-toothpaste-931.html

25 HENKELS 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. toothpaste

26 HAIR DRYERS MEMS thermopiles monitor the hairs temperature while drying and help to automatically regulate the heat output to reduce damage to the hair

27 NANO-CERAMIC PRODUCTS 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 art/251916/138779/Hairdresser-using-a-curling-iron

28 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 corrosion- resistant, strong and formable Some shavers have small OLED displays to illustrate the batterys remaining life removal/electric-shavers/

29 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 can expect salary offers of $100,000
