Chemical name: Hydrolyzed Casein
Common names: Casein Hydrolysate, Hydrolyzed Milk Protein
Appearance: Off-white to yellowish powder, faint dairy odor
Main uses: Food industry applications, dietary supplements, laboratory media
Origin: Milk protein subjected to enzymatic or acid hydrolysis
Solubility: Dissolves readily in water, forming slightly cloudy to clear solutions
Main users: Food processors, research labs, nutraceutical companies
Physical hazards: Powder may cause respiratory irritation if inhaled, dust can settle on surfaces, creating slip risks
Health hazards: People with milk allergies or sensitivities might react, skin contact rarely causes irritation, eye contact can cause mild discomfort
Environmental hazards: Not known to pose significant environmental threats under normal handling, spills in waterways unlikely to create toxic effects
Signal words or pictograms: Typical labeling lacks hazard pictograms as it is not classified under GHS as hazardous, but standard precautions are followed where allergies are a concern
Substance: Hydrolyzed Casein
Chemical formula: Mixture of peptides and free amino acids from casein breakdown
Key components: Derived from milk casein, contains peptide fragments of varying molecular weights, trace lactose and minerals from milk may remain
Allergenic potential: Dairy origin makes it unsuitable for those with milk allergies
Inhalation: Move person to fresh air, monitor for signs of allergic response, rinse mouth and nose gently with water if coughing or throat irritation occurs
Skin contact: Wash skin thoroughly with soap and water, remove contaminated clothing if irritation develops, consult a physician for persistent rash
Eye contact: Rinse immediately with clean running water, gently separating eyelids, seek medical advice if discomfort does not resolve
Ingestion: Rinse mouth with water, never induce vomiting, seek attention if allergic reactions, such as swelling or difficulty breathing, become apparent
Suitable extinguishing media: Water spray, foam, dry chemical, or carbon dioxide
Combustion hazards: Dust may fuel a fire in confined spaces, decomposition products may include carbon monoxide, carbon dioxide
Special safety procedures: Firefighters need self-contained breathing apparatus, avoid stirring up powder in the air during cleanup after a fire event
Personal precautions: Avoid breathing dust, use suitable masks if a large quantity is spilled, ventilate enclosed areas immediately, watch for slippery residues after spills
Cleanup procedures: Scoop or vacuum material into sealable containers for proper disposal, avoid dry sweeping to keep dust down, wash area with water to eliminate residue
Environmental precautions: Prevent large amounts from entering drains, minimize release into soil to protect local water quality
Handling practices: Work in well-ventilated spaces, avoid dust generation, wash hands after handling, refrain from eating or drinking in processing areas
Storage conditions: Keep in tightly sealed containers, away from strong odors, direct moisture, or sunlight, store at ambient temperature in a dry place
Preventive measures: Segregate from strong oxidizers and acids, post allergy warnings prominently
Engineering controls: Use local exhaust ventilation where dust appears, maintain good hygiene facilities on site
Personal protection equipment: Dust masks or respirators if airborne levels exceed comfort, gloves to reduce skin contact, safety goggles if transferring bulk quantities
Exposure guidelines: No established workplace exposure limits, but keeping airborne dust low follows good industrial hygiene practice
Appearance: Light to yellowish-white powder
Odor: Slight protein-like or dairy scent
pH (solution): Typically mildly acidic to neutral, varies depending on the degree of hydrolysis and concentration
Melting point: Not applicable since decomposition occurs before melting
Solubility in water: Readily dissolves, sometimes leaving a slight haze
Bulk density: Moderately light, settles over time during storage
Stability under normal handling: Remains stable in cool, dry conditions
Chemical stability: Stable in sealed packaging under recommended storage
Conditions that provoke reactions: Strong oxidizers, acids, and bases can break down peptides further, avoid high humidity which encourages clumping or spoilage
Hazardous decomposition: Burning or extreme heating releases carbon oxides and possible nitrogen oxides in smoke
Oral toxicity: Generally regarded as safe to ingest for healthy individuals with no milk allergy
Dermal contact: Skin reactions are rare, mainly limited to allergic responses
Eye contact: Short-lived discomfort, extensive or ongoing irritation is infrequent
Respiratory exposure: Dust can irritate sensitive airways, asthma or allergy sufferers might react
Environmental persistence: Degradable by soil microbes, broken down by waterborne bacteria
Aquatic toxicity: No significant risks to aquatic life observed at normal concentrations
Bioaccumulation potential: Bioaccumulation unlikely, natural breakdown occurs in most environments
Precautions for large spills: Prevent entry into streams or lakes only as a best practice to avoid nutrient loading
Recommended methods: Small quantities can go with normal organic waste, larger amounts should be handled according to local waste management rules
Recycling and reuse: Reuse or composting possible if not contaminated
Environmental impact: Low risk if disposed of responsibly, avoid burning in open conditions due to smoke
UN classification: Not regulated as a hazardous material for road, air, or sea
Special handling during transit: Secure containers tightly, keep dry, protect from direct sun or moisture which can degrade product during shipping
Spill response during transport: Gather spilled powder quickly, contain for disposal, report allergies if exposed staff react
Food safety regulations: Hydrolyzed casein follows basic food safety rules, included on GRAS (Generally Recognized as Safe) lists for many countries
Workplace labeling: Requires allergy warnings and standard identification, no major restrictions in most regions
Occupational health standards: Companies follow general good manufacturing practices, especially regarding dust, labeling, and hazard communication for milk-derived proteins
