ROTOFORM BEAD PRODUCTION FOR COSMETIC BASE INGREDIENTS

Mass production of cosmetic products requires industrial quantities of base materials, and easy transport, storage, handling and dosability of these ingredients is essential.

Rotoform systems

IPCO’s Rotoform system, first used for chemical solidification more than 40 years ago, is capable of solidifying low and high viscous melts (up to 40 000 mPas) at temperatures up to 300 °C. A range of systems enables processing of everything from micropastiiles and small batches of between 10-20 kg/hr (important where small quantities of expensive materials are used), to high capacity requirements of 3 000 kg/hr.

Bead production using Rotoform systems

The product is delivered to the system in melt form. The Rotoform consists of a heated cylindrical stator and a perforated rotating shell that turns concentrically around the stator. Drops of the product are deposited across the width of a continuously running stainless steel cooling belt.

System enhancements for GMP compliance

While the Rotoform process is inherently clean and hygienic, a GMP-compliant process requires additional properties and features

These include all-stainless steel framework and piping and the use of food grade lubricants. Other features can include special materials for seals and gaskets, a Rotoform drive with belt instead of chain, and an enclosed belt washing box with hot water or steam spraying nozzles and subsequent jet air for drying.
