GHS classification by the OSHA Hazard Communication Standard (29 CFR 1910.1200): Not a hazardous substance or mixture.
GHS Label Elements: Pictograms: N/A; Signal word: N/A.
Hazard and precautionary statements: None
Hazards not otherwise classified (HNOC) or not covered by GHS:None
Appearance: White to off-white powder
Odor: Odorless or slight characteristic odor
HPMC Full Form: Hydroxypropyl Methyl Cellulose
Solubility: Soluble in cold water (forms colloidal solution)
Viscosity: Varies by grade (e.g., 5–200,000 mPa·s at 20°C, 2% aqueous solution).
pH: ~6.0–8.0 (1% aqueous solution).
Stability:
Reactivity: Inert to most chemicals; avoid strong oxidizers (e.g., peroxides) and concentrated acids/bases.
Acute Toxicity:
Oral (LD50): >5,000 mg/kg (rat, OECD 423) – Practically non-toxic (GHS Category 5 or unclassified).
Dermal/Irritation: Non-irritation to the skin (OECD 404); mild eye irritation (OECD 405).
Inhalation (LC50): Not applicable (low dustiness, non-volatile).
Sensitization:No evidence of skin sensitization (OECD 406).
Chronic Effects:
No carcinogenicity (IARC/EPA unlisted), no reproductive toxicity.
Prolonged dust inhalation may cause respiratory irritation (mechanical effect).
Biodegradability:
Readily biodegradable (OECD 301B, >60% in 28 days).
Ecotoxicity:
Aquatic: LC50 (Daphnia magna) >100 mg/L – Low toxicity (GHS unclassified).
Terrestrial: No significant effects on soil organisms.
Environmental Fate:
Degrades via microbial action; no bioaccumulation (log Kow: -2.5).
OELs:
Not established (low hazard); general dust limit (e.g., 10 mg/m³ total dust).
Engineering Controls:
Local exhaust ventilation for powder handling.
Personal Protective Equipment:
Gloves: Nitrile or latex (minimal risk).
Eye Protection: Safety goggles if dust generation is possible.
Respirator: N95 mask for prolonged high-dust operations.
Personal precautions, protective equipment, and emergency procedures:
Avoid dust formation. Avoid breathing vapors, mist, or gas.
Environmental precautions: Do not let the product enter drains.
Methods and materials for containment and cleaning up:
Sweep up and shovel. Keep in suitable, closed containers for disposal.
Suitable extinguishing media: Use water spray, CO₂, or dry chemicals;
Special hazards arising from the substance or mixture: Carbon oxides
Advice for firefighters: Use a self-contained breathing apparatus (SCBA) for firefighting when required.
Inhalation: Move to fresh air.
Eye/Skin contact: Rinse with water for 15 minutes.
Ingestion: Rinse mouth; drink water (no induced vomiting).
Storage condition: Dry (<60% RH), closely sealed
Recommended storage temperature:Recommended storage temperature see product label.
More information on storage stability: Keep away from incompatible materials (oxidizers).
Precautions for safe handling: Provide appropriate exhaust ventilation at places where dust is formed.
Classification: Non-hazardous waste in most regions.
Disposal Methods: Landfill or incineration (follow local regulations) following the national and local regulations.
GHS Label : None required (non-hazardous per most jurisdictions).
Standards:
FDA: 21 CFR 172.874 (food-grade approved).
EU: REACH registered; E464 (food additive).
China: GB 1886.102-2016 (food safety standard).
