thermoscientific APPLICATION NOTE Extrusion of color cosmetics Author Dirk LeisterThermo Fisher Scientific， Karlsruhe，Germany Executive summary Color cosmetics are a fast-growing segment of the cos-metics and personal care products market. Manufacturerscan gain a competitive advantage by developing morenew formulations for this segment at a faster pace. Compounding solutions from Thermo Fisher Scientific canhelp speed up the process for formulation development ofeyeshadow.Utilize a parallel twin-screw extruder to mixpowder and liquid ingredients into a homogeneous productwithin a single process. The compact design of the Thermo ScientificTM Process 11Hygienic Extruder allows users to optimize the processand develop new cosmetic formulations on a laboratoryscale， with significantly reduced test time， sample sizeand waste. The challenge Within the cosmetics industry， decorative cosmetics arethe fastest growing segment. Consumers’desire for newand innovative products has generated a high demandfor new mascara， eyeshadow or facial makeup products. Developing new formulations in batch processes is quitetime consuming， requiring repetitive steps of milling andblending until the final product homogeneity is achieved. Transitioning from batch to a continuous process reducesthe number process steps and gives a distinct advantageto manufacturers of cosmetic products. The result of sucha transition is a more homogeneous product and a largernumber of new formulations for the same amount of timespent in the laboratory.

An eyeshadow formulation usually consists of fillers， absorb-ents， binders， colorants and preservatives 2]. Most often thepigmented powder products are mixed first with the basematerial (e.g.， talc) for a proper color extension， which setsthe appearance that the product will have after the custo-mer has applied it. After having achieved the desired degreeof homogeneity in the mix of initial substances， the remainingingredients are added. The more sensitive components areoften mixed mildly toward the end of the process. Fig. 2 shows a typical setup of a screw that has differentmixing zones as well as openings along the processing areato introduce ingredients throughout in the process. Inaddition to powder materials， liquids such as silicone oilsmay also be added during the compounding process. At the end of the extruder barrel， a die can be mounted topress the material through giving it a preliminary shapethat helps to facilitate the final filling process into godets.Figures 1 and 3 show an example setup of eyeshadowformulation being processed on a Process 11 benchtoptwin-screw extruder. The powder and liquid componentsare mixed continuously within the extruder and the result-ing compound is formed by pressing it through a die. Fig. 3： Pressing the final formulation through a die. Conclusion Combining different process steps into one continuouslyoperating instrument， a twin-screw extruder can help sig-nificantly speed up formulation development of new makeupproducts. The precise control of process parameters alsomitigates or even eliminates the risk of batch-to-batchvariations. The modular setup of the Process 11 instrumenthelps manufacturers adapt their analyses for differentprocess requirements. Process 11 Hygienic Extruder： The Process 11 Hygienic Twin-Screw Extruder has specialfeatures and benefits for cosmetic applications： -Compact bench-top extruder with small footprint - Intuitive process control via touch screen with data logging - Allows setup， testing and cleaning by a single user in alaboratory environment -Eight electric， heated and actively cooled temperaturezones for exact temperature control and temperatureprofiles - Seven positions along the process to feed multiplecomponents like powders， water， oil or waxes - Flexible screw design with interchangeable mixing andconveying elements， to optimize the compounding ofingredients - Suitable for scale-up to industrial production Further information We invite you to learn more or contact us to see how wecan support you at thermofisher.com/cosmetics.
