A fragrance-free travel kit

The short version

Two separate questions decide a fragrance-free travel kit. The first is size: what the security line lets into a cabin bag. The second is content: whether each small container is actually free of fragrance. The first is a rule you can look up. The second is a label-reading job, and the size of the bottle does not change how you do it.

What TSA says about size

The US Transportation Security Administration’s liquids rule is often called “3-1-1”. On the TSA page we read, the carry-on rule is that liquids, aerosols, gels, creams and pastes must be in travel-sized containers of 3.4 ounces (100 milliliters) or less per item, and that they may be carried in a quart-sized bag. TSA adds that containers larger than that belong in checked baggage.

Most toiletry categories fall under this wording, because lotions, body washes, shampoos and creams are all liquids, gels, creams or pastes. TSA lists two exemptions on the page we read: medications, and infant and child nourishments. TSA does not say there how they are screened, so check its page before you fly.

On screening, TSA says that putting these items in the small bag and separating it from your other carry-on items “facilitates the screening process”, and that anything that alarms during screening will require additional screening. We attribute these statements to TSA and have not read any airport-specific procedure.

TSA also notes that duty-free liquids over 3.4 ounces bought for an inbound international flight may be carried in a secure, tamper-evident bag under certain conditions, though the page recommends checking them. The conditions are on TSA’s page, and we do not restate them.

What the size rule does not tell you

A small container passing security says nothing about its ingredients. For fragrance-free travel, three points from the FDA matter.

• “Unscented” is not the test. The FDA says even some products labelled “unscented” may contain fragrance ingredients, because a maker may add just enough fragrance to mask the unpleasant smell of other ingredients. Our guide on fragrance-free versus unscented covers the wording.
• Fragrance can hide behind one word. The FDA says that under US regulations, fragrance and flavor ingredients can be listed simply as “Fragrance” or “Flavor”. Where a list shows that word, the maker has not itemised what is in it. See the FDA fragrance labelling rule and how to read an ingredient list for parfum and aroma.
• Label claims are not pre-approved. The FDA says it has no list of approved or accepted claims for cosmetics, and that claims must be truthful and not misleading. A front-of-pack phrase on a travel pack is therefore not a check; the ingredient list is.

This site’s fragrance-free test looks for fragrance, parfum, aroma, perfume, essential oils or fragrance chemicals in the maker’s published ingredient list. It is our rule, not a legal definition. The overview in fragrance-free products sets it out.

How to apply this when packing

1. List what you actually use, then decide for each item whether you need it in the cabin bag or can put the full size in checked baggage.
2. For each item you already trust, find the list for the size you will carry. A mini and a full-size bottle can carry different labels. The sources we read do not say how often formulas differ, so treat the travel pack as its own product until its list is read.
3. Read the travel pack’s own list in the shop, or the maker’s page for that size, before buying. Reject any list with “fragrance”, “parfum”, “aroma”, “perfume” or an essential oil.
4. Pack them together in the quart-sized bag, as TSA describes.

Where our roundups help by category

These pages cover full-size products against the same test. Use them to find a maker whose list is clean, then look for the maker’s small size and check its list.

• Body and bath: body wash, soap and hand soap.
• Hair: shampoo and hair products.
• Underarm: deodorant.
• Skin: lotion, hand cream, moisturizer, face moisturizer, cleanser and the broader skincare roundup.
• Lips and make-up: lip balm and makeup.

We have no roundup yet for toothpaste, hand sanitizer or conditioner, so we say nothing about them here. The evidence level for each product is stated on its roundup, and whether a given size was checked is stated there too; where it is not, assume it was not.

What was not checked

We did not read airline or non-US rules, and TSA’s page did not give a per-passenger bag limit or say how solid products are treated. Refills and decanting into your own small bottles are not covered by any source we read, so we make no claim about them, including about how a transferred product keeps its label information. If you have a skin condition or a reaction history, ask a clinician or an allergy or dermatology society about what to pack; this page is not medical advice.
