Recommendation: carry solid stick or crystal underarm products in the aircraft hold when possible. Aerosol sprays and pump mists should be kept to a minimum, placed in carry-on only if each container is ≤ 3.4 fl oz (100 ml) and stowed inside a single resealable 1‑liter plastic bag for security screening.
For cabin bags: sprays, roll‑ons and creams must meet the 3‑1‑1 liquids rule (containers ≤ 100 ml, one clear bag per passenger). Liquids larger than that will be refused at the security checkpoint unless exempted as medication or baby formula with supporting evidence.
For hold baggage: most airlines accept consumer personal‑care aerosols subject to dangerous‑goods limits used by IATA and many civil aviation authorities – typically a total net quantity limit per passenger (commonly cited as up to 2 kg / ~70 oz) with a per‑item maximum (often 0.5 kg / ~18 oz). Flammable propellant products are typically prohibited from both cabin and hold. Always place cans upright, snap on the protective cap, seal in a plastic bag and cushion to prevent crushing and leakage.
Practical tips: prefer solid sticks or creams in travel tubs to avoid screening issues; transfer larger liquids into compliant travel bottles for the cabin; keep original labeling for quick verification; check the airline’s policy and the departure/arrival civil aviation authority before packing; when unsure, purchase sprays at destination or ship them separately.
Pack antiperspirant products in hold baggage with format-specific limits and protective packing
Place solid sticks and roll-ons in hold baggage without container-size limits; aerosol sprays and pump mists require extra attention – many airlines accept personal-care aerosols but commonly limit each can to about 500 ml (≈17 fl oz) and the aggregate non-flammable aerosol allowance per passenger to roughly 2 kg (≈70 fl oz). Flammable-propellant cans may be restricted or prohibited by individual carriers and national aviation authorities, so verify the operator’s hazardous-goods guidance before travel.
Packing steps
Secure lids and snap-on caps, place each item in a sealed plastic bag, cushion with clothing, and position upright in the centre of the bag to reduce impact risk. For sprays, add an extra layer of tape across the actuator to prevent accidental discharge. Avoid storing cans near heat sources; temperature and pressure changes in the hold can cause expansion – do not pack near lithium batteries or sharp objects that could puncture containers.
If a leak or stain occurs
Contain spilled liquid with absorbent material, separate affected garments, and wash as soon as possible; for carpet or upholstery treatment see how to clean carpet with cat urine. Report any damaged or ruptured items to airline staff at the ticket desk so they can note the bag and advise on inspection or disposal rules.
Aerosol and spray antiperspirant: airline and security restrictions for hold baggage
Pack aerosol and spray antiperspirant products in hold baggage only when each container is 500 ml (500 g) or smaller and the total net quantity per passenger stays at or below 2 L; any item labeled flammable or with propellants such as butane/propane must not be transported in either cabin or hold.
Carrier and security checkpoints – specific actions
Verify the carrier’s hazardous-goods guidance before travel; some airlines impose lower per-item or per-passenger limits or ban aerosols entirely on certain aircraft. Keep containers in original retail packaging with the safety cap fitted. If a can is dented, leaking, or missing a nozzle guard, remove it from your baggage. For quantities above the carrier’s published threshold, declare the item at the airline desk – failure to declare can lead to confiscation or fines.
Packing and transit recommendations
Place each aerosol inside a sealed resealable plastic bag, tape the nozzle guard, and position cans upright in the center of hold baggage cushioned by clothing to reduce puncture risk. Do not place aerosols near heat sources or battery packs. Prefer solid-stick or roll-on antiperspirants for hand baggage; for checked items, consider consolidating multiple small cans into one compliant container to keep the total under limits. For identification and easier recovery if an airline inspects baggage, add a durable tag – best luggage tags for checked bags.
Solid, stick and crystal products: packing tips to avoid damage and odors
Pack solid sticks in rigid screw‑top tins (15–50 g travel size) and place each tin inside a resealable polyethylene bag; squeeze out excess air before sealing to limit scent transfer.
Clean the rim and threads of containers before closing; wrap lids with one layer of cling film and apply a 1 cm strip of packaging tape across the seam to prevent accidental opening during transit.
For crystal salts and glass vials, cushion with 5–10 mm foam or microfiber cloth, then enclose in a small hard case or tube to prevent chipping; avoid loose placement next to sharp items.
Prevent softening: store sticks away from sustained heat sources and direct sunlight; formula softening commonly begins around 40–45 °C – if a stick softens, refrigerate upright for 4–6 hours to re‑solidify rather than freezing.
Control odors by adding an odor absorber: place a 1–2 teaspoon baking soda sachet or a charcoal pouch in the same sealed bag as the product; replace sachets every 7–10 days on long trips.
Limit quantity carried in a single container to 15–50 g for easier sealing and reduced risk of large spills; transfer a few days’ supply into travel tins rather than transporting full‑size bars.
Separate scented solids from clothing using a secondary hard container or zip bag; if a spill occurs, treat garments immediately with cold water and enzyme detergent before drying.
Label travel tins with product name and date to avoid accidental mixing of scent types; for multi‑item organization consider compartmentalized pouches or small hard boxes to keep items upright and immobile.

Roll-ons and gels: size, pressure and temperature rules for hold baggage
Pack roll-on and gel containers in leak-proof, sealed bags and limit individual bottles to 500 ml or less; decant larger quantities into purpose-made travel tubes when possible.
Quantity limits: For aerosol-format products the IATA Dangerous Goods Regulations set a maximum net quantity of 2 kg (2 L) per passenger stowed in the aircraft hold, with no single aerosol exceeding 0.5 kg (500 ml). Non‑aerosol roll-ons and gels do not have a universal civil aviation volume cap for the hold but many carriers enforce a 500 ml per item practical limit–check the carrier’s policy before travel.
Pressure effects: Pressure differentials during ascent and descent can force caps to leak or push roll‑on balls out. Reduce risk by filling containers no more than 80% of internal volume, tightening caps firmly, placing a layer of cling film directly over openings before capping, and taping the cap to the bottle. Use rigid toiletry cases or hard-sided containers to prevent impact damage.
Temperature effects: Aircraft holds may be temperature-controlled on many modern jets, but extremes are still possible on some routes. Avoid exposing products to temperatures above 49 °C (120 °F) (risk of expansion/rupture) or prolonged freezing (gels can expand and crack plastic or glass). Pack sensitive items in the centre of the bag insulated by clothing, or use a neoprene pouch to buffer short temperature swings.
Leak prevention and packing method: Place each bottle in a sealed, heavy-duty zip bag; double-bag high-value or liquid‑dense items. Surround containers with soft clothing, position them away from seams and external walls, and insert an absorbent towel or paper to catch any leaks. For roll-on heads, secure the ball with a small strip of medical tape before capping.
Special-case items: Alcohol‑based gels, high‑viscosity products and glass containers have higher rupture/leak risk–transfer to sturdy plastic travel tubes rated for pressure changes. Aerosol cans with flammable propellants are subject to stricter hazardous‑goods rules; follow IATA DGR and carrier guidance for permitted net quantities and packaging requirements.
Final check: Confirm carrier-specific size and hazardous‑goods rules before departure, label fragile toiletry cases, and isolate all liquid/gel items from electronics and paper documents inside the bag.
Flammable or pressurised aerosol antiperspirants: declaration procedure and items likely to be seized
Declare any flammable or pressurised aerosol antiperspirant at the ticket counter and present the original container(s) for inspection; failure to declare often results in immediate seizure.
- What to present: original retail packaging with ingredient list and any UN/ID numbers (UN1950 for consumer aerosols), the net weight of each can, and the total number of cans.
- Where to declare: at the ticket counter or bag-drop desk before security screening; if already at security, inform the officer and surrender the item for assessment.
- Paperwork: airlines may require a Dangerous Goods acceptance stamp or a short written declaration on their form; staff will note whether items meet carrier dangerous-goods limits.
- Inspection process: agent inspects seals and labels, checks for removable valves or damage, and verifies that propellant type and content match permitted categories. Damaged, leaky or unlabeled containers are refused.
- Acceptance vs refusal: accepted aerosols typically are tagged and placed in hold storage as per airline DG procedures. Refused items must be surrendered, returned to sender, or shipped separately as hazardous cargo by a specialist carrier.
- If refused at security: options are immediate disposal, return to the vehicle/shipper, or shipment via approved dangerous-goods channels; keep receipts for items surrendered.
Common examples of items that will be seized
- Homemade or unlabeled spray mixtures (no manufacturer label or ingredients).
- Self-defence sprays (pepper/OC sprays) in jurisdictions that prohibit carriage on aircraft.
- Refillable gas cylinders, lighter-refill cartridges, and small pressurised canisters not designed as consumer aerosols.
- Spray paint, industrial aerosols, and solvents with flammable propellants lacking passenger-appropriate classification.
- Damaged, dented or leaking cans and containers with pressure-relief failures.
Practical recommendations
- Check the carrier’s dangerous-goods guidance and national aviation authority before travelling; note that some countries and airlines ban specific propellants and self-defence sprays outright.
- Present containers at the ticket counter early to allow time for inspection or alternative arrangements; do not attempt to conceal pressurised items during screening.
- If an item is refused, request written confirmation of confiscation or disposal for records and potential reimbursement queries.
