Where can you buy glycerin?

Answer:

Purchasing glycerin

Glycerin is a colorless liquid used in soaps, skin treatments, cooking, animal care, crafts, and fine arts. It can be purchased at pharmacies (including big chains like Walmart or Target) in small quantities. Or, it can be found in bulk online or at certain supply stores. The source of this information, and more details are available at the eHow article linked below.
In addition, vegetable glycerin, which has a rich oily texture, a hypoallergenic glycerin derived entirely from vegetable oil. (Non-vegetable glycerin is usually derived from pork or other animal fats.) All glycerin with a "USP" (United States Parmacopoeia) mark is safe for food and cosmetic purposes. Vegetable glycerin can be purchased online at the Netrition link below.


I generally just go to google and put in search words like "buy vegetable glycerin."
Several popular sites that pop up are Natures Flavors, Amazon, and google products.
I would shop around to find the best price/size that fits your needs.
