Silverson Machines has released two videos in collaboration with Beauty Science Labs UK, demonstrating the capabilities of the former’s L5M-A Laboratory homogeniser mixer in two different cosmetic applications – a cold process gel and a hot process emulsion.
In the cold process gel video, Tumi Siwoku (pictured, right), principal chemist at Beauty Science Labs, walks Silverson’s James Cardus (pictured, left) through the step-by-step process of creating a clear, viscous, aeration-free gel using a Silverson laboratory mixer.
She explains how pH-sensitive polymers like acrylates copolymer respond to sodium hydroxide and how proper mixing technique makes all the difference.
In the second video, Siwoku explains the concept of a hot process emulsion and how the Silverson laboratory homogeniser enables the formation of high-quality creams and lotions.
She also explains the different phases, the ingredients in each phase and the importance of mixing each of the phases at the correct temperature.
Viewers are able to see how the Silverson Laboratory mixer is able to maintain uniform mixing throughout, delivering a consistent, stable emulsion.
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 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,” said a spokeswoman.
“With this method, ingredients are fully incorporated and any agglomerates are eliminated.”
Silverson Machines will be exhibiting at NYSCC Suppliers’ Day in New York City on 3-4 June at booth 532.
