Filter Aids and Clarifiers

One of the steps in the manufacturing of vegetable oils and animal fat derivatives (such as soaps and soap bars) is the clarification, consisting of the removal of undesirable compounds which affect the color of the final product. The raw materials used in this production stage are known as Bleaching Earths. Buntech is the pioneer in domestic manufacturing of high quality Bleaching Earths. From selected mineral supplies, and through processes developed in our Technical Center, we produce the Bleaching Earths - CLARIGEL. With a combination of knowledge, innovation and technical services, we take our Bleaching Earths to the most important companies in the edible oils and fats industry for the production of soaps and soap bars.
