Whether lipstick is considered a liquid depends on the context, particularly in relation to travel regulations. While in everyday terms, we might not think of lipstick as a liquid, some regulations classify it as such.
Lipstick Classification
According to Heathrow's website, cosmetics like lipstick can fall under the liquid rule because "a lipstick could be classed as a paste which therefore makes it come under the liquid rule". The website categories such as "creams, aerosols, pastes, gels..." are considered liquids for travel restrictions.
Why this Matters
This distinction is significant primarily for air travel. Many airports and airlines have restrictions on the quantity of liquids passengers can carry in their hand luggage.
- Example: You might be limited to carrying only small amounts of pastes, gels, and creams in your carry-on baggage, and these items must be placed in a transparent, resealable plastic bag.
Summary
Therefore, while not a liquid in the traditional sense, lipstick can be classified as a liquid (specifically a paste) under certain regulations, such as those governing air travel.
