Diatomaceous earth

Diatomaceous earth (DE) is a naturally occurring, soft, siliceous sedimentary rock that is crushed into a fine powder. It’s primarily composed of the fossilized remains of diatoms, which are tiny, aquatic organisms. DE is known for its abrasive and absorbent properties, making it useful for various applications, including pest control, filtration, and as a natural additive in products like toothpaste and paint.
Key Characteristics:
Composition: Made of fossilized diatoms, which are primarily composed of silica (silicon dioxide).
Appearance: Fine, white to off-white powder with a particle size typically ranging from 10 to 200 μm.
Properties: Abrasive, absorbent, and lightweight.
Forms: Available in food grade and filter grade.
Uses:
Pest Control:
DE can be used to control insects and other pests by damaging their exoskeletons and causing them to dry out. It’s effective against a variety of pests, including bed bugs, fleas, cockroaches, and ants.
Filtration:
DE is used as a filter medium in swimming pools and industrial applications.
Natural Additive:
DE is added to products like toothpaste, paint, and certain food products.
Other Applications:
Used in insulation, absorbents, and as a catalyst in some chemical reactions.
Safety:
Food Grade DE:
Generally considered safe for ingestion in small amounts, but its effectiveness and safety for this purpose are not well-researched.
Filter Grade DE:
Contains higher levels of crystalline silica and is not intended for ingestion.
Inhalation:
Inhaling DE dust can irritate the respiratory system and cause coughing or shortness of breath. Prolonged inhalation of crystalline silica can lead to lung problems.
Skin Contact:
May cause dryness or irritation on the skin.
Important Considerations:
Food Grade vs. Filter Grade: It’s crucial to use the correct type of DE for the intended purpose.
Safety Precautions: Wear appropriate protective gear (mask and gloves) when handling DE to avoid inhalation and skin irritation, especially when using filter grade DE.
Consult Professionals: For specific applications, it’s always recommended to consult with a professional or refer to product instructions for safe and effective use

Diatomaceous Earth
Diatomaceous Earth is a natural, inorganic mineral composed of fossilized remains of tiny aquatic organisms called diatoms. It is typically offered as a white to light gray powder with a highly porous and lightweight structure, making it an excellent adsorbent and filtration aid.

The Food Grade version of Diatomaceous Earth is specially processed and refined for use in the food, pharmaceutical, and cosmetic industries, and it is free from heavy metal contamination or harmful impurities.

Applications in Oil Filtration:
Purification and clarification of edible oils such as sunflower, soybean, palm, and canola

Removal of suspended particles, waxes, phospholipids, pigments, and undesirable odors

Suitable for degumming, bleaching, and filter press operations

Enhances production efficiency and reduces the need for frequent filter replacements

Technical Features:
High purity and free from metallic impurities

Porous structure with large surface area

Excellent filtration capacity without altering the oil’s chemical properties

Non-toxic, odorless, and safe for direct contact with food products

Advantages:
Improves clarity and stability of the final oil product

Reduces overall filtration costs

Chemically inert with oils

Complies with international standards (FDA, EU Food Grade)
