The product is produced using sulfuric acid and complies with international standards and technical requirements.
The quality of this product is first class and it also unique in that "reduces oil retention" and "increases whitening power", thus surpassing most international analogues. Comparatively less clay is required for oil bleaching and refining, resulting in cost savings and higher quality oils.
