Description

Talc is a clay mineral composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2.


Talc is used as a thickening and lubricant agent, it's udsed as ingredient in ceramics, paint and roofing material, and it s also one of the main component in many cosmetic products. Talc is also a food additive ruled as Talc E553b as defined in Article 2 of Regulation (EC) No 178/2002.

Talc presents a high number of basic properties - platyness, chemical inertness, softness, water repellency and affinity for organic matter.


Talc is an inherently hydrophobic mineral. Particles of talc have the shape of platelets due to the layered structure of the mineral. The basal surfaces are hydrophobic, while the edge surfaces are hydrophilic.


Sprayed on plants it creates a physical barrier against insects and fungus with also a highly effective protective action against sunburn.


Specifications as food grade must comply with those laid down for Talc E553b in the Commission Regulation (EU) No 231/201210:

  • Loss on drying : Not more than 0,5% (105 °C, 1 hour)
  • Acid soluble matter: Not more than 6%
  • Water soluble matter : Not more than 0,2%
  • Acid-soluble iron : Not detectable


Revelant impurities:

Arsenic : Not more than 10 mg/kg

Lead: Not more than 2 mg/kg

Asbestos free.

< 0.1% of Respirable Crystalline Silica
