He discovered glycerine accidentally while boiling collectively olive oil and lead monoxide, and he referred to as the resulting materials "the candy principle of fat," because of its slightly candy taste. Later, the French chemist Michel-Eug鑞e Chevreul named it glycerine (from glykys, the Greek phrase for sweet). Glycerine is a non-toxic, clear, viscous, water-soluble liquid with a high boiling level that may be found in both vegetable and animal fats. Chemically, it reacts like an alcohol in some situations, but it is generally stable for clinical and practical applications. Here are a simply few of the many makes use of for this miraculous stuff. Glycerine is an ingredient in many soaps, but strangely sufficient, soapmaking can also be a way to produce glycerine.
