Bleaching Earth

Original price was: $6,500.00.Current price is: $5,700.00.

Bleaching earth is a vital industrial adsorbent that purifies oils, fats, and fuels by removing impurities, improving quality, and ensuring stability. Its effectiveness, versatility, and cost-efficiency make it indispensable in food processing, biofuels, petrochemicals, and environmental applications.

 

Description

Bleaching Earth

Primary Uses of Bleaching Earth

Edible Oil Refining

  • Decolorization: Removes pigments (chlorophyll, carotenoids) from vegetable oils (soybean, palm, sunflower, etc.).
  • Removal of Oxidation Products: Adsorbs peroxides and secondary oxidation byproducts.
  • Reduction of Trace Metals: Binds heavy metals (iron, copper) that promote oil rancidity.

Mineral Oil & Petroleum Refining

  • Purification of Lubricating Oils: Removes impurities, color bodies, and residual catalysts.
  • Bleaching of Paraffin & Waxes: Clarifies waxes by adsorbing color and odor compounds.
  • Fuel Oil Treatment: Helps in reducing contaminants in diesel and other fuel oils.

Biodiesel Processing

  • Removal of Soaps & Phospholipids: Used in biodiesel refining to improve clarity and stability.

Used Oil Re-refining

  • Regeneration of Waste Lubricants: Cleans used motor oils by adsorbing sludge and oxidation products.

Secondary Uses of Bleaching Earth

Industrial & Chemical Processing

  • Purification of Fatty Acids: Used in stearic acid and oleic acid production.
  • Catalyst Carrier: Acts as a support material in certain chemical reactions.

Environmental Applications

  • Wastewater Treatment: Adsorbs oils, greases, and organic pollutants.
  • Spill Cleanup: Used in oil spill remediation due to its high absorbency.

Food & Beverage Industry

  • Clarification of Wines & Juices: Removes unwanted color and haze.
  • Animal Fat Processing: Used in lard and tallow refining.

Cosmetics & Pharmaceuticals

  • Bentonite Clay in Beauty Products: Used in face masks and skincare for oil absorption.
  • Pharmaceutical Adsorbent: Helps in purifying medicinal oils.

Other Miscellaneous Uses

  • Foundry & Metal Casting: As a binding agent in molding sands.
  • Pesticide & Fertilizer Carrier: Helps in slow-release formulations.

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE)

  • Respiratory Protection:Wear an N95 dust mask or half-face respirator in dusty environments.
  • Eye Protection:Use safety goggles to prevent eye irritation.
  • Skin Protection:Wear gloves (nitrile or latex) and long-sleeved clothing to minimize skin contact.
  • Foot Protection:Use closed-toe shoes or boots to avoid slips and spills.

Handling & Storage

  • Store in a cool, dry, well-ventilated areaaway from moisture.
  • Keep containers tightly sealedto prevent dust dispersion.
  • Use proper lifting techniques(avoid manual handling of heavy bags).
  • Avoid creating dust clouds—use gentle pouring methods or mechanical handling.

Ventilation & Dust Control

  • Work in well-ventilated areasor use local exhaust ventilation.
  • Avoid dry sweeping—use wet cleaning methodsor industrial vacuums to control dust.

Spill & Leak Control

  • Small spills:Sweep up carefully or use a HEPA vacuum (avoid creating dust).
  • Large spills:Dampen with water to suppress dust before cleanup.
  • Dispose of waste according to local environmental regulations.

Inhalation (Dust Exposure)

  • Move to fresh air
  • If coughing or breathing difficulty occurs, seek medical attention.

Skin Contact

  • Wash affected area with soap and water.
  • If irritation persists, apply a moisturizing creamor seek medical advice.

Eye Contact

  • Flush eyes with clean waterfor at least 15 minutes, holding eyelids open.
  • If irritation continues, seek medical help.

Ingestion (Swallowing)

  • Rinse mouth with water.
  • Do NOT induce vomiting.
  • Seek medical advice if large amounts are ingested.

Bleaching earth is non-flammable and non-combustible, but dust clouds may pose an explosion hazard in high concentrations.

Extinguishing Media

  • Use water spray, foam, dry chemical powder, or CO₂if surrounding materials catch fire.

Firefighter Precautions

  • Wear self-contained breathing apparatus (SCBA)if in a dusty environment.
  • Avoid creating dust clouds that could ignite
