The BELSIL® eco range currently comprises six silicone fluids. They are linear, unmodified polydimethylsiloxanes (dimethicones), which are distinguished by their low surface tension and good spreading properties. These products cover a particularly crucial viscosity range in cosmetics between 5 and 60,000 centistokes (mm2/s) and are therefore suitable for the formulation of moisturizing creams, lotions, sunscreens, shampoos, conditioners and other cosmetic preparations.
For every BELSIL® eco product there also exists a silicone fluid based on petroleum-derived methanol. Chemically speaking, both products have the same raw material base. This means that there is no problem in replacing conventional silicone fluids with their corresponding BELSIL® eco products. Technical modifications or recipe or formulation adjustments are not required.
“The demand for cosmetic products which are made from raw materials that conserve our natural resources continues to rise,” emphasizes Dr. Robert Gnann, President of WACKER SILICONES. “With our new product line we are in an excellent position to meet this demand. For BELSIL® eco, we use certified biomethanol produced exclusively from plant residue such as straw or grass cuttings.”
As biomethanol is exclusively made from renewable raw materials, the carbon balance of BELSIL® eco products is more favorable than that of petroleum-based silicone fluids. According to WACKER’s calculations, around 1.6 metric tons of carbon dioxide can be saved per metric ton of biobased silicone fluid. Gnann: “With BELSIL® eco we are not only strengthening the sustainability of our own product portfolio. The cosmetics industry can also benefit considerably from silicone products made using biomethanol and conserving resources.”
WACKER uses both petroleum-derived methanol and biomethanol. A certified mass balance procedure helps to calculate and determine the share of products sourced from biomethanol. As a result, WACKER can ensure that all BELSIL® eco products are manufactured from 100 percent plant-based and therefore resource saving raw materials. The procedure is certified according to the TÜV SÜD Standard CMS 71 and is checked every year by external evaluators.
