Description
Cottonseed Oil-Specific Activated Clay | Core Advantages
1.Targeted gossypol removal
It has a high affinity for gossypol, a toxic substance unique to cottonseed oil, effectively reducing its content to meet food safety standards.
2.High-efficiency decolorization
It deeply adsorbs dark pigments and impurities in cottonseed oil, significantly improving the oil's clarity and appearance.
3.Food-grade safety
It is non-toxic, odorless and compliant with food safety regulations, ensuring no harmful residues in refined cottonseed oil.
4.Low oil loss rate
Its porous structure focuses on adsorbing unwanted substances rather than oil molecules, minimizing oil loss during the refining process.
5.Easy filtration & regeneration
It features good filterability, enabling fast solid-liquid separation; it can be regenerated for repeated use, cutting production costs.

Suggested Use
Heat the oil to 100–120°C. Slowly add 3%–7% activated bleaching clay and stir for 20–30 minutes. Allow the mixture to settle, then remove the clay by filter press.
Notes
Store in a dry and ventilated place away from direct sunlight.
Protect the product from mechanical impact and rain.
The product begins to lose crystal water above 300°C, which may change its structure and affect the decolorization effect.
The product surface easily absorbs moisture, so moisture-proof storage is required.
