In the latest video from Silverson Machines 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 moisturisers, styling products, topical treatments, and various skincare formulations, and can be easily customised with active ingredients, fragrances, or colourants.
The gel is created using a Silverson multi-purpose Laboratory mixer. Silverson Laboratory mixers are used for a variety of mixing processes from simple liquid/liquid blending, forming emulsions and reducing particle size to more complex mixing applications. They are ideal for all routine laboratory work, research and development, QA analysis and small scale production.
The ‘standard’ L5M-A model is the latest development in high shear laboratory mixing. The advantage of a Silverson over simple agitators and stirrers stems from the specially designed rotor/stator workhead; the high speed rotation of the rotor blades draws materials into the workhead where they are intensively mixed, before being projected back into the body of the mix at high velocity. With this method, ingredients are fully incorporated and any agglomerates are eliminated.
With its integral tachometer, ammeter and programmable timer, the L5M-A offers a level of instrumentation invaluable in applications where process validation and repeatability are required.
