Citric Acid



Protex International Limited is Chinese owned and operated since 1998. Not only do we supply a full range of ingredients and additives to food, beverage and nutritional supplement manufacturers, but we also actively source the needs of animal feed manufacturers as well as companies involved in the production of non-food items such as cosmetics, soaps, detergents, cleaners and disinfectants. We are also producers of wooden flooring and veneer. Now we are expanding our base for materials to other countries as well.



The latest developments in our expansion program include our new Citric Acid and Citrate factory located in Rayong, Thailand. It is equipped with state-of-the-art equipment and machinery to generate world-class quality products and has massive production capacity. In addition to this we have established a sales office in Seoul, Korea to handle our export business of high-quality, wooden construction materials.
