  • SPHERILEX® 145: For a softer whitening experience

Evonik Business Line Silica launches new specialty product, SPHERILEX® 145, for the oral care industry. White teeth and a bright, perfect smile have been the largest oral care trend over the last decade and continues today stimulated by the visual social media environment. To meet these customer demands, Evonik now launches SPHERILEX ® as a new solution for toothpaste formulators.

With the launch of SPHERILEX® 145, Evonik introduces a new technology to the oral care industry. Thanks to the spheroidal shape of the product, high cleaning levels can be achieved while providing lower abrasion to dentin, enamel, fillings and other oral hardware. This effect also holds true in combination with other formulating whitening ingredients like phosphates and chelants.

Kristina Boedtger, Global Marketing Director for Oral Care Silica states, “SPHERILEX® 145 is our new whitening silica providing consumers with whiter smiles from their everyday toothpastes. The COSMOS label makes it ideally suited for natural products and a great addition to our diverse portfolio. Our SPHERILEX® technology really enhances customer’s formulations.”

All silica oral care products are produced under the highest safety and quality standards. SPHERILEX® 145 meets USP-NF ‘Dental-Type Silica’ and EP ‘Silica, dental type’ monographs, and is listed as a “derived mineral ingredient” in the Annex D of ISO 16128-1 with the INCI name “Hydrated Silica”. All Oral Care SPHERILEX® grades conform to COSMOS as a non-organic raw material and are certified Pareve, Kosher, Kosher for Passover, and Halal.

Evonik is a leading global manufacturer of silica. In addition to the fumed silica AEROSIL® and the precipitated silica ULTRASIL®, SIPERNAT®, ZEODENT® and SPHERILEX®, Evonik also produces silica based matting agents under the brand name ACEMATT® and other fumed metal oxides under the brand AEROXIDE®.
