CAS Number: 8013-31-8
Application: Used in probiotics, dairy fermentation, research
Supplier: Manufacturer information as per packaging
Emergency Contact: Local poison control center or emergency services
GHS Classification: Not classified as hazardous under GHS guidelines
Main Hazards: May trigger mild respiratory or skin reactions in sensitive individuals; risk mainly relates to high dust levels
Label Elements: No hazard pictogram required; precautionary language for handling biological materials
Potential Health Effects: Inhalation may irritate respiratory tract; ingestion in large quantities can disrupt gut flora for immunocompromised persons
Chemical Name: Lactobacillus casei
Concentration: Lyophilized culture, generally >90% viable organisms by weight, carrier substances vary
Common Carriers: Non-reactive substrates such as maltodextrin or skim milk powder
Impurities: None intentionally added, small amounts of production residues possible
Form: Powder or freeze-dried pellet
Inhalation: Move person to fresh air, rinse mouth and nose with water if irritation appears, seek medical attention for persistent symptoms
Skin Contact: Wash with soap and water, remove contaminated clothing; persistent soreness or rash may need medical review
Eye Contact: Flush eyes with water for 15 minutes, seek care if discomfort remains
Ingestion: Normally not harmful, but large intake may cause gastrointestinal distress; drink water, monitor symptoms, seek advice for unusual reactions
Suitable Extinguishing Media: Water spray, dry chemical, CO2, foam
Unsuitable Methods: Strong water jet could spread the powder
Hazards from Combustion: Burning can release traces of carbon monoxide, carbon dioxide, or nitrogen oxides
Protective Equipment: Standard firefighting gear, respirator if heavy smoke present
Personal Precautions: Wear dust mask, gloves, safety goggles; avoid breathing dust
Environmental Precautions: Sweep up gently, keep out of drains and water courses to prevent potential biological impact
Clean-up Methods: Use damp cloth or HEPA vacuum, collect in sealed container
Disposal: Sealed, clearly marked as biological waste; follow local regulations
Safe Handling: Work in well-ventilated area, avoid breathing dust, avoid skin and eye exposure
Storage Conditions: Keep tightly closed, store cool and dry, refrigerate or freeze as per label specifics, avoid excessive heat or moisture
Incompatibles: Strong acids, alkalis; avoid sunlight
Hygiene Practices: Wash hands after use, keep food away from work area
Ventilation: Local exhaust recommended for bulk handling
Personal Protection: NIOSH-approved dust mask or respirator for dusty conditions, protective gloves, lab coat or protective clothing, safety glasses
Occupational Exposure Limits: No established limits, minimize exposure to dust
Other Controls: Eyewash station, wash facilities near work area
Appearance: Off-white to beige powder
Odor: Faint, slightly sour or cheesy
Odor Threshold: Not determined
pH: Typically 6–7 (1% solution)
Melting/Freezing Point: Not applicable (biological powder)
Boiling Point: Not applicable
Flash Point: Not flammable
Solubility: Disperses in water
Bulk Density: 0.3–0.6 g/cm³
Stability: Stable in dry, cool conditions; loses potency with heat or humidity
Reactivity: Non-reactive with most substances in storage
Chemical Stability: Stable under recommended storage, viability declines with age, heat, and moisture
Hazardous Reactions: No dangerous reactions under normal conditions
Incompatible Materials: Strong acids, alkalis, oxidizing agents
Decomposition Products: Not hazardous under intended use
Acute Toxicity: No evidence of toxicity in healthy adults; reports focus on allergic reactions only
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Symptoms: Mild irritation possible in sensitive users, rarely allergic response
Chronic Effects: Not associated with long-term harm in non-immunocompromised persons
Cancer, Mutagenicity, Reproductive Toxicity: No reported effects
Ecotoxicity: Indigenous lactic acid bacteria; unlikely to disrupt native microflora in controlled release, large spills in aquatic environments could alter microbiota temporarily
Persistence and Degradability: Organism not persistent in harsh outdoor conditions
Bioaccumulation: No bioaccumulation expected
Mobility: Limited due to inability to multiply outside culture
Other Adverse Effects: Not noted
Disposal Methods: Incinerate or autoclave as biological waste; small amounts can go to landfill with tight containment
Precautions: Prevent release to drain and surface water, follow national and local protocols
