Product Name: Talcum Powder
Chemical Name: Hydrous Magnesium Silicate
Common Synonyms: Talc, French Chalk
Recommended Use: Body and facial powder, cosmetic ingredient, lubricant, filler in ceramics and paints
Manufacturer: Please refer to packaging or supplier
Emergency Contact: Refer to company-specific safety number provided with the product or packaging information
Hazard Classification: Not classified as hazardous in pure form under OSHA Hazard Communication Standard, but certain grades may contain asbestiform fibers and present respirable dust hazards
Signal Word: Not typically assigned
Primary Hazards: Inhalation of dust can cause respiratory irritation, long-term or repeated inhalation associated with chronic respiratory conditions
Potential Health Effects: Eye irritation, skin dryness upon prolonged contact, aspiration risk if misused near mouth or nose, potential carcinogenic risk with long-term inhalation of contaminated talc. International Agency for Research on Cancer grades inhaled talc as possibly carcinogenic to humans when containing asbestiform fibers.
Chemical Description: Hydrous magnesium silicate mineral
Chemical Formula: Mg3Si4O10(OH)2
Main Ingredients: Talc (content typically above 95%)
Impurity Information: Minor naturally occurring substances may include chlorite, dolomite, magnesite, asbestos fibers (prohibited in cosmetic grade talc). Trace crystalline silica may be present, raising inhalation safety issues.
Inhalation: Remove to fresh air, rinse mouth, seek medical attention if coughing or respiratory symptoms persist
Eye Contact: Rinse eyes gently with water for several minutes, remove contacts if present and easily doable, seek parental or medical advice if irritation continues
Skin Contact: Wash with soap and water, remove contaminated clothing, moisturize skin if dryness or irritation occurs
Ingestion: Rinse mouth, do not induce vomiting unless directed by medical personnel, seek professional care if large amounts ingested or adverse symptoms develop
Suitable Extinguishing Media: Talc is not flammable, but surroundings may burn; use water spray, foam, dry chemical, or CO2 for adjacent fires
Specific Hazards: Talcum powder itself does not support combustion, will not release hazardous fumes under normal conditions. Very fine dust in air may pose minor explosion risk in rare, confined conditions.
Protective Equipment for Firefighters: Standard protective gear including respirators for dust control
Precautions: Avoid creating dust, ventilate area, keep away from moistened floors to avoid slip hazards
Methods for Clean-Up: Scoop or vacuum up spilled powder using HEPA-filter equipped vacuum or wet methods to minimize dust. Dispose in accordance with local regulations
Personal Precautions: Wear dust mask and safety goggles if dust risk is present, gloves for sensitive skin
Environmental Precautions: Prevent bulk quantities from entering drains or waterways; sweepings may be disposed in municipal waste unless contaminated
Handling: Minimize creation of airborne dust, avoid inhalation and contact with eyes, wash hands after handling, use with adequate ventilation
Storage Conditions: Store in cool, dry, well-ventilated areas in tightly sealed containers. Avoid moisture uptake (clumps may form), keep away from incompatible substances such as strong acids. Store away from food and drink
Occupational Exposure Limits: OSHA PEL for nuisance dust: Total dust = 15 mg/m³, Respirable fraction = 5 mg/m³; ACGIH TLV: 2 mg/m³ (respirable fraction, non-asbestiform talc)
Engineering Controls: Use local exhaust ventilation and general area ventilation to keep airborne dust below permissible limits
Personal Protective Equipment: Respiratory protection (dust mask or respirator), safety goggles for dusty settings, gloves for prolonged skin exposure, protective clothing as necessary to keep talc off skin and clothes
Hygiene Practices: Avoid eating, drinking, or smoking in work area, wash hands and face after handling, use skin moisturizers to prevent dryness
Appearance: White to grayish, fine, odorless powder
Odor: None
pH: Neutral (range typically 7–9 in slurry)
Melting Point/Range: 900°C – 1000°C (decomposes)
Solubility: Insoluble in water
Density: Approx. 2.7–2.8 g/cm³
Other Properties: Stable in air, non-volatile, slippery texture, can form clumps when wet due to hydrophobic surface properties
Chemical Stability: Stable under normal temperature and pressure
Reactivity: Non-reactive with most chemicals under ambient conditions
Hazardous Decomposition Products: None under normal use. Heated above 900°C decomposes to magnesium oxide (MgO), silica (SiO2), and water vapor
Incompatible Materials: Strong acids (can decompose talc), hot concentrated phosphoric acid
Conditions to Avoid: Excessive heat, high humidity, incompatible chemicals
Acute Toxicity: Inhalation of dust may cause transient irritation of respiratory tract. Not absorbed dermally
Chronic Effects: Repeated or prolonged inhalation of respirable dust may increase risk of lung conditions, including talcosis, fibrosis, and in rare cases, cancer if asbestos contamination is present
Carcinogenicity: IARC Category 2B (possibly carcinogenic to humans if containing asbestiform fibers or used perineally); pure, cosmetic-grade talc free of asbestos not classified as carcinogenic for topical use
Other Health Effects: No evidence of mutagenicity or reproductive toxicity in humans with normal use. Aspiration risk in infants if inhaled or ingested accidentally
Environmental Fate: Non-biodegradable inorganic mineral; stays in soil and sediments
Aquatic Toxicity: Not expected to cause acute harm to aquatic organisms at typical exposure levels. Large discharges can cause siltation and disrupt habitat physically
Bioaccumulation: Not bioaccumulative
Mobility: Immobile in soil; does not dissolve in water
Other Ecological Effects: No known significant adverse ecological effects in normal consumer or industrial use scenarios
Product Disposal: Dispose of like household waste in accordance with federal, state, and local requirements unless contaminated with hazardous substances
Packaging Disposal: Rinse and recycle if possible, otherwise dispose as non-hazardous waste
Special Precautions: Prevent formation of dust during disposal, wear dust mask and gloves if handling large quantities
UN Number: Not regulated
Proper Shipping Name: Talc or Talcum Powder
Hazard Class: Not regulated
Packing Group: Not regulated
Special Transport Precautions: Maintain container integrity during transit, prevent dust leakage, handle gently to avoid packaging breakage and spills. No restrictions by air, sea, or ground for cosmetic or industrial grades not containing asbestos
OSHA: Considered a nuisance dust; pure talc not listed as a hazardous substance unless contaminated
TSCA: Listed
REACH: Exempt as a naturally occurring mineral
US State Regulations: California Proposition 65 listing if talc contains asbestiform fibers
Other Regulatory Listings: Cosmetic and pharmaceutical talc must meet standards for asbestos-free composition. Ingredient labeling required under FDA for cosmetic products. Workplace use governed by local occupational health authorities, requiring dust level monitoring and exposure controls.
