Our Vegetable Glycerin is ethically and sustainably produced from non-GMO flax seeds. It is completely palm free and is a superior, vegan, pharmaceutical quality glycerin that meets USP standards. It is carefully produced, packaged and stored to maintain the purity, freshness, humectant and other beneficial properties of this versatile product. Vegetable Glycerin is the result of a sophisticated extraction method called hydrolysis, with the final product being referred to as vegetable glycerine. This system is based on the fats and oils of a raw product that are then split into crude glycerol fats, under the combined action of water, temperature, and pressure. These temperatures can exceed 400° degrees and the material is usually kept under pressure for 20-30 minutes. After this, phase this glycerol is isolated and further distilled to result in a standard 99% pure glycerine product.
