In the cosmetics industry, the milling of raw material to a fine powder is extremely important. Often this step of manufacture defines the quality of the finished product from the consumer’s perspective. Micronisers offers a gentle, low heat method of size reduction for a variety of applications including milling off-specification product, de-lumping/ de-agglomerating raw materials and coating/dispersing of fragrances in cosmetic preparations.

Typical development includes:

Material Evaluation:

A small sample will be requested to evaluate the raw material particle size distribution and physical properties. A material safety data sheet is also requested to determine occupational exposure limits (OELs) and explosivity.

Laboratory Trial:

Low cost “proof of concept” sample will be evaluated using laboratory milling equipment and will be returned to the customer to evaluate the benefit of the milling or micronisation in their application. The laboratory trial will also allow an estimation of throughput, cost and process parameters required for commercial scale milling.

Production Scale up:

Once laboratory sample is evaluated and approved by the customer, then limits for processing parameters, defining manufacturing batch documentation, labelling, cleaning requirements and analytical method will be defined prior to the commencement of scale up production.
