Ltd. is producing the basic elements below for the pharma sector.
Thioglycolic acid (TGA), was
first developed in the early 1940's as an active material for cold wave
permanents and depilatories. TGA soon found major use as a key raw
material in the manufacture of organotin stabilizers for PVC. Other
applications in pharmaceutical, agrochemical, leather processing, and
oil field chemicals soon followed. TGA continues to be used in the
cosmetics area particularly for depilatories and hair straightening. TGA
can also be used as a water soluble chain transfer
agent for certain
acrylic polymers. In the oil field area, its anti-corrosive properties
are particularly useful in down-hole applications.
TGA's unique properties make it
an ideal candidate for a wide variety of chemical reactions including
addition, elimination, or cyclization reactions. TGA's sulfur group will
react in the presence of bases, acids, ketone groups or organic halogens.
In the presence of alcohols or amines, the carboxylic group will react
The esters of TGA, including 2-ethyl
hexyl mercaptoacetate (2EHMA) and isooctyl mercaptoacetate (IOMA), are
key raw materials because they are able to react as regular mercaptans,
remain stable for longer lengths of time, and provide a useful route to
heterocylic compounds. 2EHMA and IOMA are also key intermediates in the
manufacture of tin stabilizers for PVC.
As a leading producer of TGA and
its esters, both in the United States and Europe, ATOFINA is ready to be
your global supplier.
