Material: Elastin, an insoluble protein collected from the connective tissue found in bovine neck ligaments.
Physical State: Usually presented as a fine, light-yellow powder or fibrous off-white solid after processing.
Odor: Mild, characteristic of processed animal protein, not especially pronounced.
Common Use: Utilized in research settings, regenerative medicine studies, and some cosmetic or pharmaceutical applications.
GHS Classification: Not classified as hazardous if handled under recommended conditions; presents organic dust hazards.
Health Hazards: May cause irritation to skin, eyes, and respiratory system, especially when powder becomes airborne.
Physical Hazards: Fine organic powder can form explosive dust-air mixtures; not considered flammable in typical conditions.
Chronic Exposure: No conclusive link to chronic illness; avoid constant inhalation or skin exposure to limit risk.
Main Component: Elastin protein chain, primarily composed of hydrophobic amino acids.
Source: Purified tissue from bovine neck ligament; minimal residuals of collagen or glycoproteins.
Impurities: Processed to remove fats, salts, and cellular debris, though trace residues may persist.
Eye Contact: Rinse gently with water for several minutes; remove contact lenses.
Skin Contact: Wash with mild soap and running water; seek medical attention if irritation develops.
Inhalation: Move to fresh air, monitor for cough or persistent discomfort; seek medical support if symptoms persist.
Ingestion: Rinse mouth thoroughly; seek medical guidance as a precaution.
Suitable Extinguishing Media: Water spray, dry chemical, foam, CO2.
Special Hazards: Fire releases nitrogen oxides and carbon oxides; avoid inhaling combustion gases.
Protective Equipment: Full protective gear, including self-contained breathing apparatus, essential during significant fires.
Fire Behavior: Organic dust may contribute to fire risk; avoid excessive accumulation.
Personal Precautions: Minimize dust formation, ventilate area, use appropriate PPE.
Cleanup Methods: Sweep up without generating dust; place in sealed containers for disposal.
Environmental Precautions: Prevent entry into waterways or drains; not known to cause immediate hazards in small quantities.
Handling: Use gloves, protective clothing, and respirators where risk of dust inhalation exists.
Hygienic Practices: Clean up spills immediately, maintain clean storage spaces, avoid eating or drinking near material.
Storage Conditions: Keep container tightly closed, store in cool, dry, ventilated place; avoid sources of ignition and strong oxidizers.
Engineering Controls: Local exhaust ventilation is important in workspaces where powder could become airborne.
Personal Protective Equipment: Laboratory coats, safety glasses, gloves, and suitable dust masks or respirators.
Exposure Limits: No government-established exposure limits for elastin, though best practices align with nuisance dust limits (such as OSHA PEL for particulates not otherwise regulated: 15 mg/m³ total dust, 5 mg/m³ respirable fraction).
Form: Powder or fibrous solid.
Color: Off-white to yellowish.
Solubility: Insoluble in water, soluble in strong acids and alkaline solutions.
Odor: Mild, not offensive.
Melting Point: Not applicable (decomposes before melting).
Stability: Stable at ambient temperature, degrades with prolonged moisture or strong chemical exposure.
Chemical Stability: Stable under normal laboratory and storage conditions.
Incompatible Materials: Strong oxidizers, concentrated acids, or bases can break down protein structure.
Hazardous Polymerization: Not expected.
Decomposition: High enough temperatures or strong chemical attack lead to breakdown, producing carbon oxides, nitrogen oxides, and ammonia gas.
Acute Effects: Minor irritation expected to eyes and upper respiratory tract if dust is present; skin sensitivity rare.
Chronic Effects: No convincing evidence supports chronic toxicity in users exposed in occupational settings.
Allergenic Potential: Individuals with sensitivities to animal proteins could experience allergic reactions; symptoms may include sneezing, coughing, skin rash.
Carcinogenicity: Elastin from bovine source not listed as carcinogenic by IARC, NTP, or OSHA.
Aquatic Toxicity: No known acute hazards to aquatic life in reasonable spill quantities; large releases may contribute to oxygen demand as material decays.
Persistence: Natural biodegradation occurs gradually in soil or aquatic systems,
Bioaccumulation: Not expected due to proteinaceous nature that breaks down with microbial action.
Disposal Method: Collect into sealed containers for incineration or landfill in line with local waste regulations.
Avoid Release: Do not wash material into sewers, surface water, or drainage systems.
Hazardous Waste Classification: Not classified as hazardous waste by federal criteria, but follow regional requirements for disposal of laboratory animal byproducts.
UN Number: No specific UN number or hazard class designated for elastin from bovine ligament.
Shipping Status: Classified as non-dangerous goods under most transport regulations when packed appropriately.
Precautions in Transit: Protect from moisture and physical damage; avoid exposure to extreme temperatures or rough handling that could damage packaging and create dust.
Global Regulations: Not included in controlled lists for chemical safety (such as REACH, TSCA, WHMIS) except where animal derivative rules apply.
Labeling: Standard laboratory or research use labeling sufficient; may require additional documentation in settings with animal protein restrictions.
Worker Safety: Employers must provide training on general handling of animal-derived protein powders, including protective equipment and proper cleaning.
