Clariant TONSIL Bleaching Earth Catalyst – Frequently Asked Questions (FAQ)

Q1: What is the primary function of TONSIL Bleaching Earth Catalyst in refining processes?

A: TONSIL Bleaching Earth Catalyst is a highly active, acid-activated bentonite-based adsorbent designed to remove impurities such as polar compounds, oxidation products, trace metals, and color bodies from edible oils, biodiesel, and other organic liquids during refining or purification steps.

Q2: How does TONSIL differ from standard bleaching earths?

A: TONSIL grades are engineered for enhanced adsorption capacity and selectivity, particularly toward chlorophyll, carotenoids, and degradation by-products. They offer improved filtration performance and lower residual ash content compared to conventional bleaching clays, supporting cleaner final products and reduced processing time.

Q3: Is TONSIL suitable for use in food-grade applications?

A: Yes — TONSIL Bleaching Earth Catalyst is manufactured under strict quality control and complies with international food safety requirements for processing aids in edible oil refining. It is widely accepted for use in food-grade systems where regulatory approval for clay-based adsorbents applies.

Q4: What factors influence the optimal dosage of TONSIL in a given process?

A: Dosage depends on feedstock quality, desired purity level, temperature, contact time, and equipment configuration. It is typically used at low concentrations and generally ranges from 0.1% to 2% by weight of the treated material — optimization is recommended via lab-scale trials prior to full-scale implementation.

Q5: Can TONSIL be regenerated or reused after processing?

A: No — TONSIL is intended for single-use as a disposable adsorbent. Once saturated with contaminants, its adsorption capacity is significantly reduced and regeneration is not commercially viable or recommended for maintaining consistent product quality and process reliability.
