Bleach Master

Activated Bleaching Earth for Edible Oil Refining

Acid-activated montmorillonite clay with industry-leading bleachability, low oil retention, and consistent quality — batch after batch.

Product Overview

Bleach Master

Bleach Master is our flagship activated bleaching earth — manufactured from carefully selected montmorillonite clay deposits, acid-activated at our Bhuj-Kachchh facility using a controlled sulphuric acid treatment process.

The activation process expands the clay's surface area to 290–310 m²/g, creating a highly porous structure with optimal acidity (pH 4.0) for adsorbing pigments, phospholipids, oxidation products, trace metals, and soaps from crude edible oils.

The result: clarified, colour-stable oil with improved oxidative stability — meeting the quality standards required by food-grade edible oil processors.

Technical Specifications

Complete Product Specifications

All specifications are tested and certified by our in-house quality control laboratory for every production batch.

Parameter Specification Significance
Appearance Off-white to light beige powder Consistent particle character
Bulk Density 0.55 g/cc Optimum for dosing equipment
Moisture 5–8% Prevents clumping, ensures flow
Residual Acidity ≤ 0.1% (as H₂SO₄) Safe for food-grade processing
Bleachability ≥ 75% Primary performance metric
Oil Retention ≤ 20% Lower = more yield per cycle
Surface Area 290–310 m²/g High porosity = more adsorption
pH (2% suspension) 4.0 Optimal for edible oil refining
Oil Applications

Engineered for Your Oil Type

Bleach Master's balanced pH and high surface area deliver effective bleaching across all major edible oil types.

Soybean Oil

Effective chlorophyll and carotenoid removal. Compatible with continuous and batch refining at standard dosage 0.5–1.5%.

Palm Oil

Superior carotene decolorisation. Works in both Physical Refining and Chemical Refining pathways for CPO and RBDPO.

Rice Bran Oil

Efficient wax and oryzanol adsorption alongside standard colour body removal. Reduces gummy deposits.

Sunflower Oil

Removes chlorophyll (critical for sunflower) and improves Lovibond colour scores. Low dosage requirement.

Peanut / Groundnut Oil

Reduces red pigment bodies and phospholipid residues post-degumming. Improves clarity and shelf life.

Industrial / Waste Oil

Effective for regenerating used industrial oils. Reduces colour, acidity, and oxidation products to reusable quality.

Why Bleach Master

The Refiner's Advantage

01

Reduces Refining Loss

≤20% oil retention means 80%+ of trapped oil is recoverable — directly improving your refinery's yield and profitability per tonne processed.

02

Consistent Colour Performance

Batch-to-batch bleachability ≥75% ensures your finished oil meets spec every cycle without over-dosing or re-processing.

03

Fast Filtration

Optimised particle size distribution results in clean filter cake formation and fast filtration — reducing cycle time in your bleacher unit.

04

Technical Support

Our team provides dosage recommendations, troubleshooting assistance, and specification consulting for your specific oil and process conditions.
