Compressibility and cohesion ImerCare® 100% natural talcs improve cohesion in dry and wet processed powders
ImerCare 100% natural 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.
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
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.
All ImerCare® talc grades are Cosmos approved. Certificates of origin and additional documentation are available upon request.
We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
