The types of equipment for the decomposition of oils and fats

Process Features: o Tailor-made design for crude glycerine feedstock with different quality and impurities o High yield o Refined glycerine product with low ester content and good color o Continuous salt removing with decanter system particularly (*suitable for crude glycerine from biodiesel plant)

Production of Vegetable Glycerine

There are two different types of glycerine − vegetable and petrochemical glycerine. Nowadays, the petrochemical production process is only seldom used. Vegetable oils, so-called triglycerides form the basis for the production of glycerine.
Today, vegetable glycerine is produced on a large scale using three established processes. What they have in common is that the glycerine is a by-product of a reaction that is mainly used to manufacture another product. Glycerin is therefore a so-called co-product.

• 
  Saponification – co-product in soap production 
  
• 
  Hydrolytic cleavage – co-product in fatty acid production 
  
• 
  Transesterification – co-product in biodiesel production
  

Uses of Vegetable Glycerine

Cosmetics

As it is harmless for health and environment, skin-friendly and odorless, glycerine is used both as a humectant and an emollient in cosmetics, personal care products and household products.
In creams, glycerine is a moisturizing component. It supports skin care and, at the same time, prevents the cream from drying out. As glycerine is also odorless, it is a good base for adding perfume and is used as a substance carrier in personal and hair care products.
The production of toothpaste, for example, is a large area of application. Here glycerine is used to improve the taste, prevent dehydration and lend a shine. Toothpaste can contain 20-30% glycerine.
