Update and info on glycerine.

I've spoken to a techie from this company and he told me...

Glyceryn BP 100% v/v (E422) (mine is Thornton and ross) is a vegetable glycerine derived from coconut oil. It is pharmaceutical grade and although he couldn't tell me whether this was comparable to food grade it is intended to be ingested internally so he saw no problems with adding it to a cart or liquid and ingesting it this way.

This glycerine is a bottle i bought from a supermarket for mixing with lemon juice to sooth sore throats.



Edit: Food grade is apparently not tested as thoroughly as pharm grade for safety, purity and raw materials.

Great thread, very useful Jedi

That information on BP/USP pharmaceutical grade being tested for safety more that food grade is interesting. We've had a few conversations about that here and nobody knew which was best. You seem to have answered the question. Was it the manufacturer who told you that?

Here are a couple of links that folk might find useful -

36mg + Xmg =24mg?

The company was Thornton and Ross. When i looked up the make of the glycerine i had in my cupboard it seemed they supply a lot of the UK. Im not sure about supplies to other countries. I saw on another thread though not on the beginners forum that someone had asked about some glycerine they had bought and it was also BP v/v (E422). I dont know if is also vegetable based but it seemed a coincidence.

I discovered that Food grade and pharm grade Glycerine must be at least 95% pure and the differences between Food grading and Pharm grading is that with food, the grading only really applies to the beginning products which go into the finished product. With Pharm grading all ingredients are tested both at the beginning and the end for purity, potency, safety and efficiency.

Unfortunately the place i got the grading info wasn't reffering to Glycerine in particular but dietary supplements.

Another issue im really not sure about yet is that with Pharm grading being a purer product does this make it a more dangerous product. I don't know. On my bottle of Glycerine it does state that if taken in large doses it is harmful.

Also (and interestingly) possible side effects of Glycerine are Headaches, nausea, vomiting, stomach upset, diarrhoea, thirst, dizziness, mental confusion, irregular heartbeat and severe dehydration. Diabetics are advised to stear clear.



And from another site:http://www.panama-guide.com/article....61014223042713

Several grades of glycerin are marketed, including high gravity, dynamite, yellow distilled, USP (U.S. Pharmacopoeia), and CP (chemically pure). USP grade is water-white and suitable for use in foods, pharmaceuticals, and cosmetics, or for any purpose where the product is designed for human consumption.

Im guessing then that BP is for British Pharmacopoeia.
