Tareq, welcome to the forum. I cannot answer that question specifically. The VG recommended here in the states has to be 99.5 % pure. We are advised to look for the U.S.P. label (pharmaceutical grade, which is higher than the food grade).
Edit: I looked at the product web page, and Bells is owned by a company in India. Other than that I couldn't find any information on the specific product. It appears it is sold in Europe, so maybe one of our european vapers will have the answer.
