Mannual
of Glycerin Product
Glycerin,s chemical name is propanetriol,with the chemical formula
of C3H5(OH)3
and the chemical weight of 92.It is an important basic organic chemical
raw material,applicable to such manufact uring
industries as dynamite,pharmaceutical,synthetic resin,polyether,
cosmetic,tobacco and food.
The biologically transformed glycerin produced by our factory is
much better in product transforming rate, product quality and product
output than the glycerin produced with other processes,thanks to
its unique process,advanced technique,and high technical content.
It has much lower level in such important indexes as the content
of chloride, heavy metal,arsenic and ash than the glycerin produced
with other processes.Presently it has developed such various serial
products as those of pharmaceutical grade,food grade and industrial
grade with different purity,different usage etc.It has shown its
unique superior performance at domestic and international markets,and
is paid high regards by customers from all circles.
Glycerin has very strong water absorptivity,so it can be oxidized
and decomposed under the action of sunlight,air,and bacterium.Consequently,it
should be hermetically sealed during transportation,application
and storage.
