Nanoparticles in Dunkin’ Donuts? Do the math!
Over the past couple of years a number of articles have been posted claiming that we’re eating more food products containing nanoparticles than we know (remember this piece from a couple of weeks ago?). One of the latest appeared on The Guardian website yesterday with the headline “Activists take aim at nanomaterials in Dunkin’ Donuts” (thanks to @HilarySutcliffe for the tip-off).
While I’m sympathetic to the desire for consumers and consumer groups to know what’s going into food products, what caught my eye in this case is an analysis of the amount of nanoparticles in donuts that I just couldn’t make sense of. So I indulged in a bit of nano-donut math.
As You Sow ask for nano-clarity
First thought, the Guardian piece draws on the environmental group As You Sow’s campaign to raise awareness and transparency of the use of nanomaterials in food products, and their recent shareholder resolution to Dunkin’ Brands (who own Dunkin’ Donuts). This resolution requested that Dunkin’ identify products that may contain nanomaterials, and prepare a report assessing the risks of using these substances in foods. (18.7% of shareholders voted for the resolution).
This resolution was in turn based on a 2013 report from As You Sow that asked a commercial test lab (Analytical Sciences LLC) to measure the quantity of titanium dioxide (TiO2) nanoparticles in various donut product covered in powdered sugar.<more>

Reduce customs duty on titanium dioxide to 7.5%: Nadir Godrej
Customs duty on raw materials/feedstocks, which are short-supply in domestic market and are used in paints, polymers & plastics, and antimony trioxide industries, should be lowered
PPG is in the process of expanding its coatings business, having just bought Pittsburgh, US-based competitor Masterwork Paint Company for an undisclosed sum.
With the new government all set to take charge, CII National Committee on Chemicals has put forth its expectations from the new government for the benefit of the chemical industry. Given below are some of the recommendations for the chemical industry.
Manufacture of paint involves mixing of a wide variety of raw materials in various proportions. On an average raw materials account for 56% of the total expenditure in paint companies. Raw materials used can be broadly divided into three major groups - pigments (such as titanium dioxide, zinc oxide etc), solvent (such as mineral turpentine, ethylene glycol), and resins & adhesives
Titanium dioxide is the vital pigment used in paints. Pigments and preparations containing 80% or more of titanium dioxide are also used in paints. In the Budget 2012, customs duty on titanium dioxide under CTH 2823 00 10 was reduced from 10% to 7.5% to bring at par with other inputs vide sl. no. 150 of customs notification 12/2012. However, customs duty on this has been again increased to 10% with effect from May 8, 2013. The concessional customs duty of 7.5% needs to be restored to create differential in duty between paints and this vital input. Titanium dioxide also falls under CTH 3206 as pigments and preparations based on titanium dioxide. This is evident from antidumping duty customs notification 85/2009 on titanium dioxide where in both CTH 2823 and 3206 are mentioned. Therefore, customs duty on pigments and preparations of titanium dioxide under CTH 3206 11 also needs to be reduced from 10% to 7.5%.<more>
India’s Getting a New Titanium Plant
Style: Commentary Category: Company News, Ferrous Metals, Macroeconomics, Public Policy
India’s state-owned National Aluminum Co Ltd (NALCO) has signed a Memorandum of Understanding (MoU) with another public sector company, Indian Rare Earths Ltd (IREL), to jointly set up a titanium slag plant.
That could be good news for India’s space program. Why? The project envisages adding value to Ilmenite, a titanium-iron oxide mineral, to produce the slag. Slag is an intermediate product for making titanium sponge and titanium pigments. Titanium sponge is a porous substance formed in the first stage of processing of the naturally available titanium. The latter is high strength but has low density properties, and is also corrosion-resistant. It’s widely used in the manufacture of aircraft, among other things. Titanium-alloy components are also used to make missiles and satellite launch vehicles.
Incidentally, just a few weeks ago, The Indian Space Research Organization (ISRO) launched five foreign satellites, marking an important milestone in its space program.<more>

New nanoprocess will improve coatings
Sandia National Laboratories has come up with an inexpensive way to synthesize titanium-dioxide nanoparticles and is seeking partners who can demonstrate the process at industrial scale for everything from solar cells to light-emitting diodes.
Titanium-dioxide (TiO2) nanoparticles show great promise as fillers to tune the refractive index of anti-reflective coatings on signs and optical encapsulants for LEDs, solar cells and other optical devices. Optical encapsulants are coverings or coatings, usually made of silicone, that protect a device.
Industry largely has shunned TiO2 nanoparticles because they’ve been difficult and expensive to make, and current methods produce particles that are too large.
Sandia became interested in TiO2 for optical encapsulants because of its work on LED materials for solid-state lighting.
Current production methods for TiO2 often require high-temperature processing or costly surfactants – molecules that bind to something to make it soluble in another material, like dish soap does with fat.
Those methods produce less-than-ideal nanoparticles that are very expensive, can vary widely in size and show significant particle clumping called agglomeration.
Sandia’s technique, on the other hand, uses readily available, low-cost materials and results in nanoparticles that are small, roughly uniform in size and don’t clump.
“We wanted something that was low cost and scalable, and that made particles that were very small,” said researcher Todd Monson, who along with principal investigator Dale Huber patented the process in mid-2011 as “High-yield synthesis of brookite TiO2 nanoparticles.”<more>

Benjamin Moore sued for racial discrimination after paint company 'named brown hues after black employee'
Clinton Tucker worked for the company's website in New Jersey starting in 2011
He says he was fired for repeatedly complaining about their paint colors Clinton Brown and Tucker Chocolate
A black New Jersey man is suing his former employer Benjamin Moore for discrimination after he says the paint company named two brown paint tones after him.
Clinton Tucker's suit claims he was given the boot in March after he repeatedly complained about the colors Tucker Chocolate and Clinton Brown.
Tucker alleges one of the colors was a part of the company's Williamsburg Collection, a project he helped market.
A New Jersey man named Clinton Tucker is suing former employer Benjamin Moore, claiming discrimination regarding the paint company's colors "clinton brown" and "tucker chocolate."

Note: This is a repetition of the last month. We will come up with a new session next month
I hope that you and your family are well. Long time no see. How is your business?
I have a question, regarding Qualicoat Class 1 approval. For polyester-TGIC powder coating the gloss should not be less than 50% after 1000 hours Xenon Arc exposure.I want to know if a powder based on a standard polyester-TGIC resin will pass this test (approximately equivalent to 1year Florida). Or do we need another type of polyester resin for class1 or no?
My pleasure will be hearing from you.
All is well here. We celebrated our oldest daughter's birthday today. It was a wonderful day. I hope you and your family are well. And my business is doing well – we continue to grow each year.
A standard grade TGIC-polyester will meet the Qualicoat Class 1 specification. It is important to confirm mortar and sulfuric acid resistance performance and to select your polyester resin from a reputable resin supplier. In addition it is wise to make sure that the pigments and additives are weather resistant. Some waxes are not UV durable. In addition many organic pigments will fade from one year Florida exposure. So choose you additives and pigments wisely.
I hope that this helps.
What is the best way to measure weatherability and cheapest way?QUV,Xenon Arc or Solarbox?I want to get machine for my laboratory.What is your suggestion?
The very best way to ascertain resistance to outdoor conditions is natural exposure (this is expensive and takes years). Second best weathering simulation technique is exposure to concentrated sunlight through the use of solar reflectors and water mist and is commonly known as EMMAQUA or equatorial mount with mirrors for acceleration and water (ASTM D4141). This technique utilizes real solar energy but because the energy is concentrated by mirrors the duration is significantly reduced. ASTM D4141 testing requires the careful measurement of UV light exposed to. The amount measured is then compared to historical data of Florida exposure and correlated to the number of months of typical exposure. This is also very expensive.
Next best technique is Xenon Arc Weatherometer (ASTM D-6695). For artificial tests the wavelengths of xenon arc emission best simulate sunlight. These cabinets are relatively expensive to buy and costly to operate.
Click here for answer with pictures and graphs
Next in relevance is QUV (ASTM D-4587). This is tried and true, but not as representative of sunlight as the tests described above. I would use 340-A lamps as the shorter wavelengths (B-313) are selectively too damaging to polyester resin backbones. QUV cabinets are much less expensive than Xenon Arc units. I bought a used one for less than $2000. New ones cost around $10,000 to $12,000.
You may want to consider building a rack and exposing test panels at your own facility as well.
Hope this helps.
