The concentration of the therapeutic compound in the microreservoir droplets is between 4070% by weight of the saturation concentration, wherein the amphiphilic solvent is diethylene glycol
The next step was adding 9% diethylene glycol
(DEG) to the resin and then repeating the test to see if there would be a difference.
Richard Brooks, from the county's trading standards team, said: "The recent discovery of fake tubes of Sensodyne toothpaste, with no active ingredient and contaminated with toxic levels of diethylene glycol
, on sale at car boots in the UK, is also a reminder that counterfeit goods can also be of poor quality and unsafe, thus putting consumers at risk."
All the tubes of fake Sensodyne contaminated with toxic levels of diethylene glycol
should be thrown away.
is usually used in antifreeze but can be used to thicken toothpastes as a cheap alternative to glycerine.
The New York Times reported on the weekend that the Taixing Glycerine Factory in eastern China's Jiangsu province had passed off cheap diethylene glycol
as glycerin, an additive in many medicines and foods.
The firm's production permit has been revoked, the reports said, adding the company apparently used much cheaper diethylene glycol
instead of propylene glycol in making the drugs.
Ethylene glycol will undergo a list price increase of $0.06 per pound in North America and diethylene glycol
will undergo a list and off-list price increase of $0.03 per pound in North America.
On the other hand, the diethylene glycol
scandal in Germany, if overblown, was giving winegrowers there fits.

This report summarizes the preliminary findings of this ongoing investigation, which indicate that this outbreak was associated with diethylene glycol
(DEG)-contaminated glycerin used to manufacture acetaminophen syrup.
Shrinking profit margins are promoting a shift from the older phthalic anhydride process to dicyclopentadiene (DCPD), since the latter process permits the use of lower cost ethylene glycol and diethylene glycol
. However, DCPD-based resins are more difficult to formulate and require greater technical competence.
