Cold Process Gel with Beauty Science Labs

Watch Tumi Siwoku, Principal Chemist at Beauty Science Labs, and James Cardus from Silverson Machines as they demonstrate how to formulate a Cold Process Gel using a Silverson Laboratory Mixer.

In this video, Tumi shares her experience in the cosmetics industry and walks through the step-by-step process of creating a clear, viscous, aeration-free gel. Learn how pH-sensitive polymers like acrylates copolymer respond to sodium hydroxide and how proper mixing technique makes all the difference.

The resulting product is a cold-processed gel base. These neutral gels are widely used across the cosmetics and personal care sector, serving as the foundation for gel moisturizers, styling products, topical treatments, and various skincare formulations, and can be easily customized with active ingredients, fragrances, or colorants.
