Yes, You Can Take Bar of Soap on a Plane Because soap bars are considered solids, they aren't subject to the same rules as liquid items. In other words, you can pack your favorite soap bar without worrying about a TSA agent throwing it away at the checkpoint.
Since a bar of soap is a solid rather than a liquid, TSA puts no restrictions on bringing them through airport security. You can bring a bar soap of any size or as many bars as you wish. And that's true for both your carry-on bag and your checked luggage.
Cosmetics (including soap and hair care products)
Cosmetic products are allowed into Australia if they are commercially manufactured and packaged and for the personal use of the person wishing to import the item. You may bring up to 10 kilograms or 10 litres for personal use.
This includes all drinks, toiletry and cosmetic items such as shampoo and shower gel, toothpaste, liquid/aerosol deodorant, hairspray, hair gel, mascara and foundation cream. It does not include solid deodorant sticks and solid bars of soap.
Firearms, ammunition, and fireworks are prohibited, as are all knives and safety razors (including pocket knives and Swiss Army knives). Straight razors and replacement blades for straight razors are also not allowed. Most tools also cannot be packed in carry-on luggage, as they have the potential to cause harm.
Most importantly, they should never be stored in something that is airtight - like a ziplock plastic bag.
A shampoo bar and body bar - or obviously, one that combines them both - is 100% easier to travel with. You can pack it anywhere. Don't need to take it out at security. And since most of those other products are all water based - the cost of use over time is WAY higher.
Absolutely, you can bring body wash in your carry-on bag, but while abiding by the TSA 3-1-1 liquids rule. Fill containers with a body wash. These must be less than or up to 3.4 ounces (100 ml). Put all of the containers in a quart-sized bag.
Since toothpaste is considered a liquid, paste, or gel by the TSA, most of us toss those tiny one-ounce tubes in our carry-on bags. However, if you want to ditch the hard-to-recycle packaging, consider toothpaste tablets, an ecofriendly alternative that's not subject to the 3-1-1 rule.
Limits on liquids, aerosols and gels
All liquids, aerosols and gel items must be in containers of 100 millilitres or 100 grams or less. Containers must fit into one transparent and re-sealable plastic bag, like a snap-lock bag.
In general, you may want to opt for stick products since they're easier to control and cause less product waste during use. You can carry a solid deodorant of any size onto your flight and don't have to adhere to a 3.4 oz rule.
Stick deodorant is fine in any size. Well, almost any size… Powders and crystals are good to go as well. Spray, Gel, Liquid, Cream, Pastes, and Roll-On deodorants need to be in containers no larger than 3.4 ounces and placed in a clear quart-sized baggie.
Deodorant And Antiperspirant Sizes
For example, many stick deodorants and antiperspirants come in sizes under 3.4 ounces, so it's fine to bring in your carry-on bag. However, roll-ons tend to be larger, meaning they must be packed in checked luggage.
Additionally, it's worth noting that the Centers for Disease Control and Prevention (CDC) makes no distinction between handwashing with liquid soap or bar soap to prevent sickness and endorses both types of soap equally.
Additional studies have been done over the years where environmental bacteria has been found on bar soaps, as well as the surface of liquid soaps. But, none have shown to be a source or risk of infection. Both liquid and bar soaps are equally cleansing.
And EVEN you're not sharing with family, numerous studies have shown that although bacteria levels on a used bar of soap are slightly higher than on unused soaps, there are no detectable levels of bacteria left on the skin's surface after using a bar of soap.
Soap bars love hanging out in a cool, dry place. Something like a drawer, a dark closet, or leave them in the shipping box it arrived in. If a bar is left in direct sunlight it is much more likely to experience what we call "scent fade".
Brush Down, Shake Out
Start by shaking out your bag to get rid of loose dust, dirt and crumbs. If you have a large, clean, soft bristle brush – like those used to clean suede shoes – gently brush the outside of your bag to knock off dust and dirt. If you don't have a brush, dust it off with a towel.
Tips on traveling with liquids limit
TSA has a limit on the size of liquids, gels and aerosols that travelers can bring in their carry-on bags. It's called the 3-1-1 liquids rule. Each item must be 3.4 ounces or less and must be able to fit inside a one-quart size clear zip-top bag. The limit is one bag per person.
Do not pack you portable charger (power pack) in hold luggage: Taking your portable phone charger (power pack) on a plane is fine, but just remember to pack it in your hand luggage. Do not put them in your hold luggage as this is not permitted and could result in your luggage not being loaded.
TSA classifies both solid deodorant and lipstick as solids. Neither needs to go in your liquids bag.
TSA considers tweezers to be completely safe, so they're allowed on planes. You can pack tweezers in hand or checked baggage without any packing restrictions. But TSA doesn't allow packing sharp objects in hand baggage because some of them could be used as potential weapons.
