5. NANO AND CONSUMER PROTECTIONS
“IN NOVEMBER 2009, THE EUROPEAN
UNION PASSED A LAW THAT WILL SOON
FORCE MANUFACTURERS OF COSMETICS
TO STATE ON THE LABEL IF THEIR
PRODUCTS CONTAIN NANOPARTICLES.”
GOES IN EFFECT JULY 2013
THE GUARDIAN, MARCH 30, 2012 “A USERS GUIDE TO
EU COSMETIC REGULATION 1223/2009
“U.S. LAW DOES NOT SUBJECT COSMETIC
PRODUCTS AND INGREDIENTS TO PREMARKET
APPROVAL BY FDA (WITH THE EXCEPTION OF
COLOR ADDITIVES THAT ARE NOT INTENDED FOR
USE AS COAL-TAR HAIR DYES).
RATHER, FIRMS AND INDIVIDUALS WHO MARKET
COSMETICS HAVE A LEGAL RESPONSIBILITY TO
MAKE SURE THEIR PRODUCTS AND INGREDIENTS,
INCLUDING NANOSCALE MATERIALS, ARE SAFE
UNDER LABELED OR CUSTOMARY CONDITIONS OF
USE, AND THAT THEY ARE PROPERLY LABELED.”

http://nice.asu.edu/nano/nanoemulsion-techniques-enhance-effectiveness-nutraceuticals Food scientists and researchers are develioping new ways to improve neutraceuticals and the nutritional value of processed foods. Nanoemulsion techniques can increase the water solubility, increase the absorption, and decrease the amount of nutrients required to make foods more nutritious. Nanoemulsions are currently made via high-pressure homogenization, but other techniques such as ultrasonic homogenization and electrified coaxial jet emulsification are being used in lab settings to further enhance the stability and absorption of nutraceuticals. Additionally, researchers are developing nanoencapsulation techniques using micellar cells for more targeted nutrient delivery.
http://nice.asu.edu/nano/titanium-dioxide-protective-food-additive TiO2 “Titanium dioxide (TiO2) particles are used as a food additive that can prevent a broad spectrum of ultraviolet light from penetrating containers, which decreases the spoiling time and increases the shelf life of food. Titanium dioxide is also used as an additive to make food/paint/consumer goods appear white and more attractive to the consumer.” “When Titanium Dioxide is exposed to UV light, it becomes a photocatalyst and absorbs the UV light, disposing it as heat. This property allows the titanium dioxide to be used as a sterilization/anti-fouling/deodorizing/self-cleaning agent. Since titanium dioxide is not irritating to the skin, and does not discolor when exposed to UV light, it is often used in sunscreen and other products where discoloration/irritation would be a detractor to the value of the product, such as in food.”
http://www.ncbi.nlm.nih.gov/pubmed/22260395 Pub Med: This study quantifies the amount of titanium in common food products, derives estimates of human exposure to dietary (nano-) TiO(2), and discusses the impact of the nanoscale fraction of TiO(2) entering the environment. The foods with the highest content of TiO(2) included candies, sweets, and chewing gums. Among personal care products, toothpastes and select sunscreens contained 1% to >10% titanium by weight. While some other crèmes contained titanium, despite being colored white, most shampoos, deodorants, and shaving creams contained the lowest levels of titanium (<0.01 μg/mg). For several high-consumption pharmaceuticals, the titanium content ranged from below the instrument detection limit (0.0001 μg Ti/mg) to a high of 0.014 μg Ti/mg. Electron microscopy and stability testing of food-grade TiO(2) (E171) suggests that approximately 36% of the particles are less than 100 nm in at least one dimension and that it readily disperses in water as fairly stable colloids. However, filtration of water solubilized consumer products and personal care products indicated that less than 5% of the titanium was able to pass through 0.45 or 0.7 μm pores.
