The legislative voted overwhelmingly for an urgent review of the EU-wide law that makes it illegal for passengers to carry containers of liquids or gels in their hand luggage that are larger than 100ml.
In a resolution, the Parliament said that unless new evidence can be found in favour of the legislation then it should be repealed.
While promising to keep the restrictions under review the European Commission stood up against the resolution saying that the limits would remain in place until technology is found that can screen liquid containers.
As the European Parliament has limited law-making powers, the final say rests with the Commission making it unlikely that the criticisms will lead to the scrapping of the ban.
The measure was introduced in November last year after a plot to bring down US-bound planes from London Heathrow using liquid explosives was foiled by UK police.
MEPs claimed that the ban has inconvenienced passengers who have had their beauty products and medicines confiscated, and proved expensive for airports and airlines.
"The European Parliament is concerned that the cost of the regulation may not be proportionate to the added value in terms of additional security," stated the resolution.
Although the restrictions have given headaches to travelling beauty consumers, the fast-moving packaging industry has reacted quickly to help them comply with the restrictions.
This has meant that a host of new packaging products have been introduced, leading to the creation of a new niche in personal care packaging.
Graham Packaging and Alpha Packaging are among the companies that have produced packaging lines specifically designed to conform to the new regulations.
