Covalumine Pigments offer an exceptional balance of colour and transparency with a hint of pearlescence. Patent-pending and globally accepted, they provide a luxurious soft feel to applications and finish to a satiny appearance giving the impression of a natural "skin glow".

Covalumine Pigments improve product performance because Unipure™ colorants are coated onto a special platelet alumina and then surface treated to improve skin adhesion and water resistance while bonding the colorant to the substrate. This has the added benefits of eliminating dispersion problems and excessive grinding associated with traditional pigments, regularising the oil absorption of the pigment and improving formula stability. Obsessive quality checks ensure that dE<1.2 providing a consistent colour and reducing the need for significant colour modification in production.

Covalumine Pigments can be used alone, in combination with each other, or with Covapearl™ pearls enhancing the ability of the formulator to deliver unique and multiple refractive colours.
