CAS Number: 149-38-8 (Primary pigment: Monacolin K/Lovastatin)
Hazard Classification: Not classified as hazardous under GHS standards
Signal Word: None
Hazard Statements: May cause respiratory irritation if high quantities of powder become airborne; dust can cause mild skin and eye irritation
Precautionary Statements: Avoid breathing dust, wash hands thoroughly after handling, use personal protective equipment as required
Potential Health Effects: Inhalation of high volumes of dust might cause mild respiratory discomfort; skin or eye exposure can be irritating for sensitive individuals
Other Hazards: People with mold allergies or asthma may react to airborne particles; product stains skin, clothing, and surfaces
Main Ingredient: Fermented rice (Oryza sativa) colonized by Monascus purpureus mold
Pigments: Primarily monascorubrin, rubropunctatin, ankaflavin, monascin
Bioactive Compounds: Monacolin K (Lovastatin analogue), citrinin (may be present at low levels)
Additional Components: Minimal water content, trace proteins, carbohydrates, and fats from rice base
Impurities: Diligent manufacturers screen for citrinin contamination due to health concerns
General Advice: Remove from exposure, wash exposed skin thoroughly, seek medical attention if discomfort persists
Inhalation: Move person to fresh air, keep comfortable, seek medical care if breathing becomes difficult
Skin Contact: Wash gently with soap and water; stain may persist temporarily, irritation should resolve
Eye Contact: Rinse cautiously with running water for several minutes; remove contact lenses if present, continue rinsing, consult a physician if irritation persists
Ingestion: Rinse mouth, drink water; seek medical attention if large amount consumed or if feeling unwell
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemicals, or foam
Specific Hazards from Combustion: Burning may produce carbon monoxide, carbon dioxide, and minor organic gases
Special Protective Equipment: Firefighters should use full protective gear and self-contained breathing apparatus
Fire/Explosion Risks: Dust may form explosive mixtures with air if concentrations are high; avoid creating clouds of airborne powder
Advice for Firefighters: Stay upwind, contain firefighting water, avoid inhaling smoke
Personal Precautions: Avoid formation and inhalation of airborne dust, use dust mask and gloves
Spill Handling: Gather spilled material with a shovel or vacuum fitted with HEPA filter
Environmental Precautions: Keep material away from drains and water sources, prevent large releases from entering soil or waterways
Cleanup Methods: Dampen spilled powder before sweeping to avoid dust; wash with copious water, use soap to remove staining
Waste Disposal: Collect in suitable containers for approved disposal or composting
Handling: Use in a well-ventilated setting, minimize dust, avoid contact with eyes and skin, wash hands after handling
Safe Practices: Use dedicated utensils, wear protective clothing to prevent staining
Storage Requirements: Keep in tightly closed containers, store in cool, dry, well-ventilated places away from direct sunlight, moisture, and ignition sources
Incompatible Materials: Avoid contact with oxidizers, high humidity, and strong acids
Storage Life: Stable under recommended storage for at least two years
Exposure Limits: No specific occupational exposure limits established
Engineering Controls: Provide local exhaust or general room ventilation; use dust extraction when transferring bulk material
Personal Protective Equipment (PPE): Wear dust mask or particulate respirator for high exposure, protective gloves and goggles, long-sleeved clothing
Hygiene Measures: Change contaminated clothing, wash hands before eating, drinking or smoking
Environmental Controls: Avoid releases to the environment, contain spills quickly

Solubility: Partially soluble in water, soluble in ethanol
pH: Neutral to mildly acidic in aqueous suspension
Vapor Pressure: Negligible
Bulk Density: 0.6-0.9 g/cm³ (varies by processing)
Staining: Strongly stains surfaces and fabrics
Stability: Color degrades with prolonged exposure to direct sunlight or heat
Stability: Stable in original, sealed packaging under dry, cool conditions
Reactivity: Non-reactive under normal storage and usage
Incompatibility: Strong oxidizing agents, extremes of pH, moisture, direct sunlight
Decomposition Products: Thermal decomposition can produce carbon oxides and pungent organic vapors
Hazardous Polymerization: Does not occur
Acute Toxicity: Generally recognized as safe when consumed in food amounts; very large quantities may cause gastrointestinal upset or allergic reactions
Chronic Toxicity: Regular intake of high-dosed, unregulated supplements linked to mild liver function changes in some users due to monacolin K
Allergic Reactions: Possible in individuals sensitive to molds or rice proteins
Carcinogenicity: Primary concern surrounds possible contamination with citrinin (nephrotoxin and possible carcinogen)
Other Information: No evidence of reproductive or developmental toxicity in food-level exposures
Eco-Toxicity: Not identified as harmful to aquatic or terrestrial life in small quantities
Persistence and Degradability: Readily biodegradable as an organic material
Bioaccumulation: Unlikely
Mobility in Soil: Limited mobility; colored compounds may stain soil and surfaces
Other Adverse Effects: High dust concentrations may cloud waterways temporarily
Waste Disposal: Dispose of in accordance with local, regional, and national regulations; can be treated as biodegradable food waste for small amounts
Packaging Disposal: Containers may contain residue; triple-rinse and recycle or discard as solid waste
Prohibited Disposal: Do not discharge into natural water bodies or sewage systems in powder form
