Welcome to Imerys Performance Minerals

Compressibility and cohesion

Compressibility and cohesion ImerCare® 100% natural minerals improve cohesion in dry and wet processed powders

Imerys 100% natural minerals are excellent solutions for improving compressibility and cohesion in pressed powders without affecting sensorial properties.

Imerys Mica

ImerCare® 6M mica is ideal for achieving both transparency and cohesion in pressed powder compacts.

Highly prized in make-up applications, natural mica has unique optical and physical properties which make it ideal for powder foundations, eyeshadows and
blushes. However, its incorporation rate is generally limited due to the lack of cohesion it can produce in pressed powders.

Sustainably sourced from our mica deposit in northwest France, our 100% natural, ImerCare® 6M mica grade has been carefully engineered so that it can be incorporated at high levels in powder based make-up products  whilst still providing a much sought-after transparent and luminous finish.

ImerCare® 6M:

  • Can be incorporated at a high percentage
  • Is highly cohesive compared to a standard mica
  • Provides good pick-up and sensorial properties
  • Imparts high whiteness and transparency
  • Offers a good compromise between matte finish and luminosity

ImerCare® 6M is 2 x more cohesive than standard micas

Imerys Talc

ImerCare 100% talcs are ideal for preventing cracking in dry- and wet-processed pressed powders and compacts.

Compared to standard talcs and other additives used in pressed powders, our premium talc product  ImerCare® Dolce  demonstrates high fracture resistance, improving the compressibility and cohesion of dry pressed powders and compacts.

ImerCare® Dolce improves cohesion (drop test results)

Method: For each formulation, three dishes are dropped from a height (22cm) in an upright position inside a cylinder onto a glass plaque. This is repeated until the pressed powder formulation cracks and the number of drops is recorded.

We also recommend our ImerCare Talc range to improve cohesion in dry-processed pressed powders.

ImerCare® SheerSilk and ImerCare® Velluto are ideal for use in wet processes where they prevent cracking. 

The new global trend for producing pressed powders is to use a wet processing method which consists in adding the powder in a slurry form and then vacuum pressing it to produce the dry pressed powder. Conventional talcs are susceptible to cracking during this process.

ImerCare® SheerSilk and Velluto are compatible with wet processes where they prevent cracking

Photo compressed powders


All Imerys cosmetic products are natural, high quality, chemically inert and offer good skin tolerance. They are not treated with chemicals during processing. These attributes enable them to be used in cosmetic products that comply with cosmetic directive regulation (EC) n° 1223/2009.
