Common Uses: Antioxidant in food, supplement ingredient, cosmetic additive
CAS Number: 3650-09-7
Hazard Class: Generally classed as non-hazardous under typical handling conditions
Pictograms: Not usually required, but contact with eyes or skin may cause short-term irritation
Signal Word: Not assigned to high hazard, but basic protective steps make sense during handling
Routes of Exposure: Inhalation, skin, eye, and ingestion
Potential Effects: Eye stinging, mild skin irritation, coughing if dust is inhaled
Chronic Effects: Long-term risks tend not to stand out based on current data
Main Active Ingredient: Carnosic Acid
Concentration: Pure form or as rosemary extract with specified percentage
Other Ingredients: Rarely includes carrier solvents or food-grade excipients in commercial blends
Contaminants: May include trace amounts of other rosemary-derived compounds
Skin Contact: Rinse with mild soap and water
Eye Contact: Flush thoroughly with clean water for several minutes
Inhalation: Move to fresh air, seek support if symptoms stick around
Ingestion: Rinse mouth, rest, contact a health professional if feeling unwell
General Advice: Seek professional help for bothersome symptoms, avoid self-prescribing remedies
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide for surrounding area
Combustion Hazards: Smoke may irritate, burned material can release carbon oxides
Protective Equipment: Respiratory protection for fire-fighters in tightly enclosed spaces
Special Procedures: Avoid breathing dust and combustion by-products
Personal Precautions: Wear gloves, goggles, and dust mask
Spill Response: Sweep carefully to avoid raising dust, collect spill in a container
Environmental Measures: Prevent powdered material from entering drains or waterways
Clean-Up: Dispose of small residues by moist wiping, air out affected area
Handling: Keep containers closed, avoid raising dust, use in ventilated spaces
Storage Conditions: Store in cool, dry rooms away from sunlight
Incompatible Materials: Strong acids, oxidizing or reducing agents
Packing Material: Glass, plastic, or other sealed containers work best for shelf life
Eye Protection: Safety glasses or goggles reduce risk during weighing or mixing
Skin Protection: Long sleeves and gloves are practical in bulk processing
Respiratory Safety: Dust mask or particulate respirator as a realistic step for dusty tasks
Engineering Controls: Local exhaust ventilation improves air quality in confined spaces
Hygiene: Wash hands after tasks, avoid eating in work areas
Appearance: Pale yellow to off-white fine powder
Odor: Faintly herbal aroma, typical of rosemary
Melting Point: Around 195–200°C
Solubility: Not very soluble in water, dissolves better in ethanol or oils
Stability: Decomposes slowly with exposure to heat, air, or light

Other Notable Properties: Reacts moderately in alkaline media
Chemical Stability: Sits stable in sealed containers, breaks down with light, open air, or elevated temperature
Reactive Materials: Incompatible with strong oxidizing/reducing agents
Decomposition: Releases carbon monoxide, carbon dioxide when burned
Hazardous Polymerization: Not reported for carnosic acid
Acute Toxicity: Low oral and dermal toxicity based on lab data, not considered hazardous in trace dietary amounts
Skin Irritation: Mild irritation reported in rare cases
Eye Contact: Short-term burning, largely from dust particles
Respiratory Effects: Temporary coughing or sneezing if inhaled
Chronic Toxicity: Long-term adverse effects appear rare at typical exposure levels
Environmental Fate: Biodegradable in soil and water
Aquatic Toxicity: Low toxicity to fish and aquatic invertebrates at tested levels
Bioaccumulation: Unlikely due to breakdown in natural conditions
