For security reasons, the quantity of liquids and gels in your hand luggage is strictly limited. What is meant by "liquids and gels"?
Under Commission Regulation (EU) Nr. 2015/1998 LAGs carried by passengers may be exempted from screening if the LAG is:
(a) packaged in individual containers with a capacity smaller than 100 millilitres or its equivalent in one transparent, re-sealable plastic bag that can contain no more than 1 litre, whereby the contents of the plastic bag fit comfortably and the bag is completely closed; or
(b) to be used during the trip and is either required for medical purposes or a special dietary requirement, including baby food; or
(c) obtained airside beyond the point where boarding passes are inspected and from outlets that are subject to approved security procedures as part of the airport security programme. However, only on the condition that the LAG is packed in a STEB, inside which satisfactory proof of purchase is provided so that security can verify that it was bought at Brussels Airport’s airside on that day; or
(d) obtained in the security restricted area from outlets that are subject to approved security procedures as part of the airport security programme; or
(e) obtained at another Union airport, on condition that the LAG is packed in a STEB inside which satisfactory proof of purchase is provided so that security can verify that it was bought at that airport’s airside on that day; or
(f) obtained onboard an aircraft of a Community air carrier, on condition that the LAG is packed in a STEB, inside which satisfactory proof of purchase on board that aircraft on that day is displayed.
If the LAGs do not meet one of the conditions above, the LAG will be confiscated with no possibility of recovering it afterwards.
