TSA & United Airlines Liquids Rule
49 CFR § 1540.111 — Aviation Security Authority
Title 49 of the Code of Federal Regulations (§ 1540.111) dictates the 3-1-1 liquids rule for passenger cabin baggage. Containers carrying makeup brushes must be 3.4 fluid ounces (100 milliliters) or smaller by capacity. Larger containers that are only partially full are still prohibited in cabin baggage unless they fall under medical or infant care exemptions. Containers larger than 3.4 oz must be packed in checked luggage.
Security Checkpoint Screening Procedure
When passing through the TSA checkpoint with makeup brushes, place your travel-sized container (3.4 oz / 100 mL or less) inside a clear, quart-sized plastic bag. If standard 2D X-ray machines are operating at your lane, extract the quart bag and lay it flat in a screening bin. At airports equipped with modern 3D CT computed tomography scanners, you may leave your liquids inside your bag unless instructed otherwise by Transportation Security Officers. Medical liquids or baby nourishment exceeding 3.4 oz must be declared immediately prior to screening for manual inspection or explosive trace detection (ETD) testing.

Sharp beauty tools such as nail scissors under 4 inches are generally permitted; check TSA guidelines for any bladed accessories.
Place fragile glass bottles inside bubble wrap or a padded cosmetics case to prevent breakage inside your bag.
