Vegetable Glycerine EP/USP Grade Our vegetable glycerine is a clear, colourless and odourless, hygroscopic, viscous liquid with a purity of 99.5% minimum. It is a pure and natural allergen free product, derived from a variety of natural sources. It is completely biodegradable and therefore creates minimal environmental impact. Our vegetable glycerine has not been tested on animals. Our vegetable glycerine is also produced without the use of raw materials originating from the Jatropha plant or its oils - the Jatropha plant is classified as a noxious weed in some countries. The oil produced from the Jatropha plant contains carcinogenic substances and presents a significant human and animal health risk.
