Our Vegetable Glycerin is a Kosher product derived from palm, & it is GMO-free and allergen-free. Glycerin is the result of a sophisticated extraction method called hydrolysis. This system is based on the fats & oils of a raw product (typically palm or coconut) that are then split into crude glycerol fats, under the combined action of water, temperature & pressure. Vegetable Glycerin is a clear, colorless, & odorless viscous liquid. It is used as an agent in cosmetics, toothpaste, shampoos, soaps, herbal remedies, pharmaceuticals, and other household items. Because it is soluble in both, water and alcohol, its versatility is a major benefactor in its purported growth and popularity within the manufacturing sector. It is invaluable as a natural source ingredient with emollient-like properties which can soften and soothe the skin and it assists the outer epidermis to retain moisture. This helps to explain why it is one of the most popular cosmetic additives used today.
