Specialty chemicals group has created an environmentally friendly alternative to microplastic beads

Specialty chemicals group Evonik has created an environmentally friendly alternative to microplastic (polyethylene) beads in exfoliants. SIPERNAT is a specialty silica that formulators an environmentally friendly and economically viable alternative for polyethylene and polypropylene exfoliants, according to Evonik.

The company is launching two variants on SIPERNAT - SIPERNAT 2200 PC and SIPERNAT 22 PC, and reports that a number of prominent personal care players are already using the new specialty silica in their product offerings.

SIPERNAT 2200 PC features particles with a size of approximately 20μm, while the particle size in SIPERNAT 22 PC is approximately 120μm. Both formulas have a microsponge structure. In addition to providing a cleansing function, the structure also carries the advantage of absorbing liquid active ingredients and scents, holding for release at a desired point, such as the application of the end product.

The International Natural and Organic Cosmetics Association (NATRUE), lists SIPERNAT 2200 PC and SIPERNAT 22 PC as nature-identical. This means the substance (in this case silica or SiO2) is already found naturally, but is not usually available in the required purity.

"All leading manufacturers of cosmetics and body care products are currently working to replace abrasive microplastics particles," explained Andreas Fischer, head of the Silica Business Line of the Evonik Resource Efficiency Segment. "The specialty silica SIPERNAT with its high purity level is an ideal solution because it fully meets the requirements for abrasive particles."
