How Does Filtration Help?

Filtration is a critical step in the production of cosmetics and personal hygiene products to ensure that raw materials, blends and final product are free from impurities, contaminants, and particulates.

Unique filtration requirements of cosmetic formulations

Lotions and Creams – typically use a combination of surface and depth filtration to ensure a smooth texture.
Serums and Gels – often require depth filtration and fine membrane filtration for clarity and sterility.
Shampoos and Conditioners – use screen and depth filtration to remove particulate matter and ensure consistency.
Filtration of Makeup Products – ensures that products like foundation and mascara are free from clumps and contaminants.

How we can help

Filter Media Selection: Siga Filtration can help in the selection of a filter media that is compatible with the cosmetic formulation to avoid chemical reactions or degradation.
Process: We can help select the appropriate pore size based on the type and size of impurities to be removed and ensure the filtration system can handle the required flow rate without clogging or slowing down production.
Sterilisation: Our sterilising grade filters produce a sterile product and can be integrity tested to ensure compliance.
Regulatory Compliance: Our filters are constructed from FDA compliant materials and meet or exceed the requirements of EC1935/2004. The sterile membranes are integrity testable and offer the highest level of protection from biological contamination. All products for cosmetics industry meet strict quality requirements and are manufactured in the European Union and United Kingdom..

Coarse Filters or Screens

Coarse filters or screens remove large particles and protect downstream equipment. Suitable for raw materials, intermediates and viscous products.

Depth Filters

Depth filters are used to capture smaller particles throughout the depth of the filter medium. Particles are captured in progressively finer layers. Also suitable for viscous products.

Sterile Filtration

Sterile Filtration: Removes microorganisms to ensure the sterility of the product. Employs filters with very small pore sizes (typically 0.22 micron). Critical for products that need to be free from microbial contamination, such as eye drops or injectable cosmetics.
