Cosmetic eye shadows, particularly those containing glitter or metallic powders, are composed of particles with highly irregular shapes and reflective properties. These characteristics enhance visual appeal but also introduce challenges in achieving a homogeneous and stable formulation. Oversize particles or contaminants can lead to poor spreadability and uneven coverage on the skin.

The classification process is critical to remove coarse fractions and foreign bodies, ensuring a fine and consistent powder that can be easily applied. This step directly influences the final product quality, including texture, adhesion, and visual uniformity, which are key parameters in the cosmetics industry.
Vibrating sieving is particularly suitable for this application, as it allows precise separation while preserving the integrity of delicate particles. Parameters such as mesh size, throughput, and installation point must be carefully defined, especially when handling small production batches or high-value formulations.
MLT Cuccolini VPB vibrating sieves are well suited for the classification of eye shadow powders, typically installed after mixing or before final packaging. They provide accurate separation of oversize fractions while maintaining gentle handling of the product, preventing degradation of metallic or glitter particles.
For applications requiring flexibility and the ability to handle limited batch sizes, the X-Line CS multifrequency sieve offers an effective solution. Its design allows efficient sieving even at low throughputs, making it ideal for cosmetic production environments where frequent product changes and small batch processing are common.
Both solutions are available in stainless steel execution and are designed for easy cleaning, supporting high hygiene standards and minimizing cross-contamination risks. Their controlled vibration ensures consistent results while preserving the visual and functional properties of the final product.
Using MLT Cuccolini vibrating sieves for glittered eye shadow classification ensures a uniform and refined product, improving application performance and final appearance. The removal of contaminants and oversize particles also enhances product reliability and user satisfaction.
The flexibility to manage both continuous processes and small batches makes these solutions particularly suitable for the dynamic and quality-driven cosmetics industry.
