Whether face powder, compact powder, eye make-up of soft powder, microfine powders ensure intensive, uniform colors and are easy to apply evenly and comfortably. The manufacture of such high-grade cosmetic articles is complex. The production of powder mixtures made up of pigments, carriers, fragrance and care components is challenging because all constituents need to be uniformly micronized. The manufacture takes place under stringent statutory hygiene conditions.
Frequent product and color changes call for uncomplicated cleaning and a perfect cleaning result. Not least because of these challenges, many leading cosmetics manufacturers produce high-grade, cosmetic products in powder form using Hosokawa Micron/Alpine systems.
INDIVIDUAL SOLUTIONS FOR THE COSMETICS INDUSTRY
Hosokawa Alpine grinding systems are developed especially with the requirements of the cosmetics industry in mind. Not least because of our experience in the pharmaceuticals branch, our perfected cGMP system design delivers excellent results when micronising critical materials which have a tendency to deposit. It goes without saying that if the product is changed often, the system can be cleaned quickly and without residues – if desired fully automatically.
With compact systems, a maximum yield is achieved in the case of high-grade products. The optional wear protection prevents the grey film caused by metal abrasion. The high degree of automation and the comprehensive documentation guarantee constant high quality.

| Product | End-product fineness | Throughput [kg/h] | Machine size |
|---|---|---|---|
| Talc-pigment mixture | 97% < 20µm | 35 | 160 UPZ |
| Cosmetic powder | 99% < 25µm | 25 | 200 AS |
| Face powder | 99% < 100µm | 100 | 315 UPZ |
| Talc-pigment mixture | 99.9% < 15µm | 2 | 100 AS |
| Make-up powder | 99% < 15µm | 5 | 100 AS |
| Face powder | 99% < 20µm | 25 | 200 AS |
Mixing powders with the Cyclomix
The Cyclomix can produce face powders in homogeneous, lump-free batches by spraying continuously from its central spray nozzle and rotating at variable rotor speeds of 3 – 30 m/s, including low speeds gentle enough for mixing fragile or heat-sensitive components. The Cyclomix disperses pigments thoroughly and does not over-wet the mixture, eliminating the risk of lumps and the need for additional milling. This unique combination minimizes product losses and helps avoid downtime for cleaning.
Milling and micronizing face powder
Powders form a considerable part of the base materials needed for cosmetics. The production of these powders requires milling and micronizing, which is a specialism of Hosokawa Alpine. Hosokawa Alpine has established itself as an expert in dry powder processing and supplies complete systems for the formulation of powdery cosmetics. This includes systems for fine grinding of dry raw and base materials and the micronizing of face powder.
Containment Technologies
Our range of industry-leading processing equipment includes containment solutions for the safe handling of powders and solvents during the production process. The equipment is renowned for its ability to process high-grade materials, its excellent build quality and ease of cleaning, harnessing our extensive experience in the cGMP pharmaceutical sector.
The Hosokawa Group’s primary centre of expertise for containment technology is Hosokawa Micron Ltd. in the UK. Their smart downflow booths and laminar flow booths for powder and solvent handling can be fitted with their unique, dynamic Hosokawa Gen4 intelligent software, while their range of isolators, gloveboxes, drum handling and filling and weighing systems are perfect for the safe containment of ultra-fine powders, including those comprising nano-size particles.
