GHS-compliant Safety Data Sheets for every SEMISIL fumed silica grade, available in six languages with one-click download.
6 Languages available8 SEMISIL fumed silica grades coveredGHS Rev.9 Classification standard
Every SEMISIL Safety Data Sheet follows the 16-section GHS format mandated under REACH (EU) and HCS 2012 (OSHA). For fumed silica grades, the most critical sections for formulators are Section 3 (composition — synthetic amorphous SiO₂, CAS 112945-52-5 for hydrophilic; CAS 68611-44-9 for hydrophobic variants), Section 8 (occupational exposure limits — typically 2 mg/m³ respirable dust TWA per ACGIH), and Section 9 (physical properties including BET surface area, tamped density, and pH in 4% suspension). Each document is revision-controlled and updated within 90 days of any regulatory reclassification.
Select the SEMISIL grade you need from the table below, choose your language, and enter a business email address. The PDF is delivered instantly to your inbox — no approval wait. Registering your email also ensures you receive automatic SDS revision alerts whenever a document is updated for GHS harmonization changes or new toxicological data. All downloads are logged for REACH Article 31 traceability, which simplifies your own downstream-user documentation obligations.
An SDS tells you how to handle a product safely — it does not tell you how to formulate with it. For application-specific data such as viscosity build curves, recommended loading levels (typically 1–5 wt% for thixotropy, 3–8 wt% for reinforcement), and dispersion parameters (rotor-stator at 10–20 m/s tip speed), refer to the corresponding Technical Data Sheet in our TDS Library. For ISO 9001 and IATF 16949 certificates of compliance, see the Certifications page. For a broader view of how fumed silica is classified across REACH, TSCA, K-ECLA, and KKDIK, visit our Regulatory Overview.

The library covers all SEMISIL hydrophilic grades (150–380 m²/g BET range) and hydrophobic grades (100–200 m²/g BET range, surface-treated with DDS, HMDS, or PDMS), plus the SEMISIL H100 matting grade (230–270 m²/g). Documents are available in English, Chinese, German, Spanish, French, and Japanese — matching the six primary regulatory jurisdictions where SEMISIL fumed silica ships. If your jurisdiction requires a specific local-language SDS not yet listed, request it through the download form and our regulatory team will issue it within five business days.
| Grade | Type | BET (m²/g) | SDS Languages |
|---|---|---|---|
| SEMISIL 150 / 200 / 300 / 380 | Hydrophilic | 150–380 | EN, CN, DE, ES, FR, JA |
| SEMISIL R272 | Hydrophobic (DDS-treated) | 100 ± 20 | EN, CN, DE, ES, FR, JA |
| SEMISIL R620 | Hydrophobic (HMDS-treated) | 200 ± 20 | EN, CN, DE, ES, FR, JA |
| SEMISIL R202 | Hydrophobic (PDMS-treated) | 100 ± 20 | EN, CN, DE, ES, FR, JA |
| SEMISIL H100 | Matting (treated) | 230 – 270 | EN, CN, DE, ES, FR, JA |
Download the SDS for any SEMISIL grade in your preferred language — then pair it with the matching TDS for complete formulation and handling guidance.
Each SEMISIL SDS contains all 16 GHS-mandated sections: hazard identification, composition (CAS 112945-52-5 for hydrophilic, 68611-44-9 for hydrophobic), first-aid measures, handling and storage guidelines, exposure controls (2 mg/m³ TWA respirable dust), and physical-chemical properties including BET surface area and tamped density.
Synthetic amorphous fumed silica is not classified as a carcinogen under GHS — that classification applies only to crystalline silica. SEMISIL grades carry no H-statements for chronic toxicity. The primary workplace hazard is respirable nuisance dust, managed by keeping airborne concentrations below 2 mg/m³ TWA.
SDS revisions are issued within 90 days of any regulatory reclassification or new toxicological finding. Routine reviews occur annually. Registered users receive email alerts automatically when a new revision replaces an existing document, ensuring your files stay audit-ready.
All major SEMISIL grades have SDS in six languages: English, Chinese (Simplified), German, Spanish, French, and Japanese. These cover REACH, TSCA, K-ECLA, ISHL, and most LATAM regulatory jurisdictions. Additional languages are available on request within five business days.
An SDS covers safe handling, hazard classification, exposure limits, and emergency response — it is a regulatory compliance document. A TDS covers product performance: BET surface area, particle size distribution, viscosity build data, and recommended loading levels for specific formulation applications.
Yes — a business email is required. This enables automatic revision alerts so your files stay current for audits, and satisfies REACH Article 31 traceability requirements for downstream-user SDS distribution chains. The PDF is delivered to your inbox instantly after registration.
