Glycerin
Also known as: Glycerol
What it is: A viscous, crystalline liquid formed when FAT molecules
split, forming free fatty acids and glycerin. About half as sweet as sugar,
glycerin is used as an ADDITIVE to keep baked goods, jelly beans,
marshmallows and even tobacco moist, to plasticize cheese, gelatin desserts,
processed meats, hot fudge sauces and chewing gums. GENERALLY RECOGNIZED AS
SAFE when used according to FDA standards.
************************************************
I got this by consulting the http://www.askjeaves.com search engine site.
There's loads of other information there regarding glycerin, but the links
are so long they'd take up more space than my letter, and I couldn't weed
out the important bits.
The pure chemical product is called glycerol, and is an alcohol. The impure
product is glycerin. Glycerin is always present during the making of soap,
however large manufacturers have the means to separate the glycerin from
their less expensive products. They then use it to create more expensive
products, or sell it as a separate product. Home soapmakers cannot (and
probably would not) perform this complex process, and so their soap retains
the natural glycerine content. No wonder I like it better.
