Diatomite - Damolex C

Damolex C (calcined Diatomaceous Earth) is used as a carrier, an absorbent and as a soil / turf coditioner.

Diatomaceous Earth is an absorbent mineral formed from the remains of diatoms, and is composed mainly of amorphous (non-crystalline) silica.  Alternative names include diatomite and kieselguhr. 
Diatoms are microscopic unicellular algae of the phylum Bacillariophyta, and can occur in marine or fresh water. Structurally in two halves – hence their name - their cell walls are impregnated with silica which builds up into large beds.  Diatomaceous earth is therefore found close to the sites of current or former water bodies.

Calcined diatomaceous earth has been processed by heating to a high temperature, converting much of the amorphous silica into crystalline forms.  This improves the mineral's absorption properties, and enables the manufacture of robust granules which won't break down when they become wet.


The properties which make diatomite valuable include low density, high porosity, high surface area, abrasiveness, insulating properties, inertness, absorptive capacity, brightness, and high silica content.   Diatomite has a wide variety of uses, and is a component in hundreds of products, or vital to the manufacturing process of thousands more.

Functional Additives:  In paints, diatomite alters glass and sheen, extends primary pigments, adds bulk and strength, controls permeability and enhances coating adhesion.  In plastics, diatomite serves as an antiblocking agent which helps in the separation of plastic parts in manufacturing, and in the separation of plastic bags by the consumer.
Absorbents:  Due to such characteristics as porosity and high surface area, diatomite is highly absorbent and is very useful in the clean-up of spills in the automotive, industrial, janitorial and waste remediation industries. 
Soil Amendments:  When Diatomaceous earth is incorporated into soil, it serves to reduce compaction, and increase water and air permeation.  It also increases plant available water, firms soggy soils, loosens hard to work soils, provides better drainage, aids in nutrient transfer, and improves root growth. In such applications as golf courses, and other landscaped areas it helps absorb and hold water, reducing the amount of water used.
DE is excellent for breaking up and conditioning heavy clay soils. For sand soils it helps prevent water naturally draining away but holds it in place for plants to take up.
It can be mixed with fertilisers or applied directly to soil. As a rule of thumb use at a ratio of 1:10, Diatomaceous Earth to soil.

HAZARD IDENTIFICATION: Classification (EC 1272/2008)
Physical and Chemical Hazards: Not classified.
Human health: Not classified.
Environment: Not classified.
Classification (67/548/EEC): Not classified.
Human health
This product does not meet the criteria for classification as hazardous as defined in the
Regulation EC 1272/2008 and in Directive 67/548/EEC. Depending on the type of handling
and use, airborne respirable crystalline silica may be generated. Prolonged and/or massive
inhalation of respirable crystalline silica dust (particles up to 10 microns in size) may cause
lung fibrosis, commonly referred to as silicosis. Principal symptoms of silicosis are cough
and breathlessness. Occupational exposure to respirable crystalline silica dust should be
monitored and controlled.
The product is not expected to be hazardous to the environment.
Physical and Chemical Hazards
This product is an inorganic substance and does not meet the criteria for PBT or vPvB in
accordance with Annex XIII of REACH. This product should be handled with care to avoid
dust generation.
