2. INTRODUCTION
• Nanotechnology-
– National Nanotechnology Initiative (NNI)
definition
I. Research and technology development at the atomic,
molecular, or macromolecular levels (1-100nm)
II. creating and using structures, devices, and systems that
have novel properties and functions because of their size
III. The ability to control or manipulate on the atomic scale

3. APPLICATIONS OF NANOMATERIALS
Biomedical
Optical
Electronic
Mechanical
Consumer goods
 Foods
 Cosmetics

4. Potential Uses of Nanomaterials in
Foods
• Dietary supplements
– Nanosized mineral supplements which have
dramatically increased absorption
– Nanoemulsions that increase absorption of
botanical ingredients
• Enhance flavor and color

5. Potential Uses of Nanomaterials in Foods
• Decrease microbial contamination in food and
improve packaging
– Nanocomposite minimize the leakage of carbon dioxide
– Kill microbes directly- Silver Nanoparticals

6. – Sensor to alert consumers or retailers of potential
spoilage
– Tracer to identify the source of contamination

7. • Titanium nitride was approved as a nanosized
recycling aide for polyethylene terephthalate
(PET) used as food contact material

8. Uses of Nanomaterials in Cosmetic
Products
• Nanodispersed Systems
– Liposomes (nanosomes)
– Nanoemulsions
– Solid lipid nanoparticles
• Other Nanoparticles
– Metal Oxide Nanoparticles

9. Nanodispersed Systems
 Liposomes – lipid bilayer
 Nanoemulsion and lipid
nanoparticles – lipid monolayer
 Core can be hydrophilic or
hydrophobic depending on the
number of phospholipid layers
 Deliver water or lipid soluble
ingredients

10. Cosmetic Nanoemulsions
• Nanoencapsulation of
ingredients
• May be found in skin and
hair care preparations
 Useful in typical cosmetic
formulations
 Light or oxygen sensitive
actives can be protected
 Vitamin A and Vitamin E

11. Potential Lipid Nanoparticle
Advantages
• Improved stability of ingredients
• Controlled release of ingredients
• Improved skin hydration
• Incorporation of lipophilic ingredients
• No or low carrier biotoxicity

12. Solid Hydrophobic Nanospheres
• Highly cationic charge density of surface layer leads
to strong interaction with skin/hair
• Solid hydrophobic core protects water soluble and
volatile ingredients
• Found in fragrances, vitamins

13. Metal Oxide Nanoparticles
• Metal oxides, such as TiO2 and
ZnO, are found in many
commercial applications

14. Potential Advantage of Metal Oxides
• Small crystal size and controlled particle size
give excellent dispersibility, make skin feel
attractive, and is transparent on the skin
• May increase
protection against
both UVA and UVB
rays
