Cosmetic additives with function
Alumina
In the field of cosmetics, aluminium oxide alumina is successfully used in toothpaste. This gives a particularly high degree of whiteness. In the discussion about aluminium, it is important to point out that this is the chemically inert aluminium oxide and not a salt or an easily soluble compound. The INCI designation that can be used here is: Corundum, as it is Al₂O₃ in all cases. It is also used by the dentist for professional tooth cleaning.
Zink Oxides
We also offer zinc oxide in cosmetic quality. Zinc oxide has an anti-inflammatory, anti-irritant, antimicrobial and drying effect. As it has a high covering power, reflects visible light and effectively absorbs UV radiation in micronised form, it is also used in sun creams. To cover a broad spectrum, it is often combined with micronised titanium dioxide. Micronised zinc oxide must be declared as a nanomaterial.
Kaolinite
The naturally occurring mineral kaolinite is a phyllosilicate. The name kaolinite is derived from the rock kaolin, of which it is the main component.
Kaolinite has a Mohs' hardness of 2 to 2.5, a density of 2.61 to 2.68 g/cm³. In water, the mineral becomes plastically deformable. The mineral is ubiquitous as aluminium silicate in the soils of warm, humid regions. It is purified and calcined before it is used in industry. In cosmetics, it is found in exfoliating masks and as a thickening component. It is also an alternative to plastic-based thickeners, depending on the formulation.
