Cosmetics Sterilization

UHT Infusion for Cosmetics


SPX FLOW is a world leader in UHT technology with a comprehensive portfolio of tried and tested UHT plant solutions including plate, tubular, injection and infusion UHT plant technologies. Infusion is the most efficient technology for UHT sterilized products. UHT infusion involves heating products very rapidly from 20°C to 150°C with clean steam, keeping the product at that temperature for a few seconds and cooling it down to 30°C very rapidly. The high temperature, combined with strong thermal shocks, destroys the most resistant micro-organisms. The rapidity of heating and cooling avoids any product deterioration. This treatment is applied to end products and the equipment can be easily installed between existing process tanks and filling machines.

Why UHT treat cosmetics?

Cosmetics usually contain different chemical additives in order to avoid bacteria and fungi contamination. But more and more consumers are concerned about possible health effects that preservatives such as parabens in cosmetics present. Alternatives to preservatives, such as alcohol or essential oils…can also create allergies. A unique solution to avoid using additives is sterilizing products with Ultra High Temperature (UHT) treatment. The product must then be filled in adequate packaging to keep the sterility, even after use by the consumer. SPX FLOW brand APV has applied its vast knowledge of UHT systems, and adapted UHT infusion, to cosmetic applications.

UHT Pilot Plant to test your Products

SPX FLOW Innovation Centre:

The SPX FLOW Innovation Centre operates several UHT pilot plants capable of running all the main UHT systems. These pilot plants are used for product testing and new process development. Our customers also test new processes and optimize existing process parameters assuring production scalability. Because the centre is equipped with mixing tanks, aseptic filling machines, complete laboratory facilities and all utilities, customers can simulate complete process line before investing.
