Conventional four step production of high quality face powders, requiring multiple machines is now being replaced by single machine mixing using the Hosokawa Micron Cyclomix.
Schematic of the Hosokawa Micron Cyclomix.
Unlike other cosmetic production processes no mill is required for dispersion of lumps. Lower investment costs, reduced cleaning and maintenance downtime and improved product quality are driving this change across the cosmetics industry.
It is essential that the fine cohesive powders used in face powders, eye shadows and blushers are mixed accurately and gently to produce the smooth, homogenous and streak free products that end users desire and this can be achieved consistently and quickly in the Cyclomix. The intensive but gentle mixing action of the Cyclomix is ideally suited for these requirements and with its constant circulation of the product the Cyclomix leaves little product residue within the unit after discharge making the machine easy to clean and improving yields.
The Hosokawa Micron Cyclomix is effective running batches from 20 to 100 percent of the working volume with product quality maintained.
CASE STUDY
Application:
Intensive mixing of pigments and talcum and addition of oil for the production of face powders.
Requirements:
- Homogenous pigment dispersion without streaking
- Lump free incorporation of up to 25% of oil
- Damage free mixing of brittle and heat sensitive materials
Solution
The Cyclomix disperses the pigments completely. Oil is introduced from the top of the mixer with the position of the nozzle guaranteeing good distribution of the liquid in the powder. During introduction of the oil the mixer maintains mixing so there is no over-wetting of parts of the mix and no lumps are formed. Due to the ability in changing the rotor speed from 3-30m/s it is possible to introduce fragile materials or pearls at the end of the batch and mix them gently without destroying the product structure.
Summary
Due to this unique combination product losses are minimal and down time for cleaning minimised.
