As a result of this guidance (FAQ 6.3.8. onhttp://echa.europa.eu/reach/faq_en.asp), to (pre)-register the chemically surface treated products, it isnecessary to (pre)-register the base particles (i.e., synthetic amorphous silica) and the surface treatmentsubstances.• We confirm that Cabot Corporation haso registered untreated fumed silica under REACH, meeting the December 1, 2010 deadline (REACHRegistration Number: 01-2119379499-16) and

opre-registered the surface treatment substance• The different obligations within the EU REACH legislation are described in a specific Cabot REACH statementseparate from the present one. This statement is regularly updated to address the list of Substances of VeryHigh Concern (SVHC) which is frequently modified by the EU Authorities. The current version of Cabot’sREACH statement is available from our website in the “Downloads” section at www.cabot-corp.com. Pleaserefer to this informationNOTE: Non-EU producers that import substances into the EU may need to use the service of our OnlyRepresentative to be covered under REACH. For further information, please contact your Cabot salesrepresentative.Inorganic and Organic ImpuritiesCAB-O-SIL® hexamethyldisilazane (HMDZ) treated fumed silica products are not routinely analyzed for thepresence of the following organic and inorganic impurities. To the best of our knowledge, Cabot Corporationbelieves these chemicals are not present in the raw materials used in the manufacture of our CAB-O-SIL®hexamethyldisilazane (HMDZ) treated fumed silica products nor are these substances used in our production andhandling processes. Therefore, they are not expected to be present in CAB-O-SIL® hexamethyldisilazane (HMDZ)treated fumed silica product(s) above trace concentrations (i.e., low ppm or less).Organic Impurities• Acrylamide• Aliphatic and aromatic solvents• Azo compounds, aromatic amines and dyes• Bisphenol A diglycidyl ether (BADGE); Bis (hydroxyphenyl) methane bis (2,3-epoxypropyl) ethers (BFDGE);and novolac glycidyl ethers (NOGE)• Endocrine disrupters, such as phthalates and bisphenol-A• Furans• Formaldehyde• Glycol ethers• Aliphatic chlorinated hydrocarbons, dioxins, polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls(PCBs), polychlorinated terphenyls (PCT), and fluorinated hydrocarbons• Brominated hydrocarbons and flame retardants, such as polybrominated biphyenyls (PBB), polybrominateddiphenyl ethers (PBDE), pentaromodiphenyl ether (pentaBDE), and octabromodiphenyl ether (octaBDE)• Ozone depleting substances (ODS), such as CFCs and HCFCs• Hazardous air pollutants (HAPs), as defined by United States regulations and EU directives• Latex• Organotin derivatives• Phenols• Perfluorooctane sulfonates (PFOS ) and Perfluorooctanoic acid (PFOA) and its salts as regulated by EUDirective 2006/122/EC• Pesticides, insecticides, fungicides (including Dimethyl Fumarate – DMF as regulated by EU Directive2009/251/EC), rodenticides, herbicides and biocides• Volatile organic compounds (VOCs), as defined by United States regulations and EU directivesInorganic Impurities• Asbestos• Heavy metals: lead, mercury, cadmium, and hexavalent chromium – are not intentionally added to CAB-O-SIL® hexamethyldisilazane (HMDZ) treated fumed silica products during their manufacture or handling

processes. In addition, to the best of our knowledge, the sum of the incidental concentration levels of lead,mercury, cadmium and hexavalent chromium present in a CAB-O-SIL® hexamethyldisilazane (HMDZ)treated fumed silica product does not exceed 100 parts per million by weight.RoHS EU Directive 2002/95/EC as amended and modified by Commission Regulation 2005/618/ECCabot Corporation does not routinely test its CAB-O-SIL® hexamethyldisilazane (HMDZ) treated fumed silicaproducts for the presence of RoHS substances. However, to the best of our knowledge, Cd, Cr VI, Hg, Pb,polybrominated biphenyls or polybrominated diphenylethers derivatives (including decabromodiphenyl ether) are notused during the production of Cabot HMDZ-treated fumed silica products.Presence of GMOTo the best of our knowledge, Cabot Corporation’s CAB-O-SIL® hexamethyldisilazane (HMDZ) treated fumed silicaproducts do not contain any genetically modified organism (GMO) products or materials, nor do they come intocontact with any GMO product or material during their manufacture and handling.Products of Animal OriginTo the best of our knowledge, Cabot Corporation’s CAB-O-SIL® hexamethyldisilazane (HMDZ) treated fumed silicaproducts do not contain any product of animal origin, nor do they contain any animal product associated with BovineSpongiform Encephalopathy (BSE) or Creuzfeldt-Jakobs Disease (CJD). The regulated chemicals that typically areassociated with the development of BSE or CJD are not involved in the production and handling processes of ourCAB-O-SIL® hexamethyldisilazane (HMDZ) treated fumed silica products.EU Food Contact InformationPlease contact your Cabot Area Sales Manager for specific information.US Food Contact InformationNot permitted for direct nor indirect food contact use.Japan Food Contact InformationNot permitted for direct nor indirect food contact use.Pharmaceutical InformationNot permitted for pharmaceutical use.Cosmetics ApplicationsThese products have the following INCI (International Nomenclature of Cosmetic Ingredients) names assigned byThe Personal Care Products Council (formerly called Cosmetic, Toiletry, and Fragrance Association - CTFA) andcan be included in cosmetic preparations for their designated uses with no restrictions:‘SILICA SILYLATE’ - CAB-O-SIL® hexamethyldisilazane (HMDZ) treated fumed silica and similar products for useas antifoaming agents, emollients and viscosity controlling agents.Cabot CAB-O-SIL® hexamethyldisilazane (HMDZ) treated fumed silica products have not been tested for cosmeticpurposes. CAB-O-SIL® hexamethyldisilazane (HMDZ) treated fumed silica products have been tested in animals forskin sensitization/irritation effects and have been designated as non-sensitizing and non-irritating. See section 11 ofthe product’s material safety data sheet (MSDS) for additional toxicology information.Cabot has and will perform animal testing when required by law and/or when it is necessary to protect the health ofour employees and customers.
