Alternative items that would also be useful if you happened to have them.
OATMEAL - In the post apocalyptic world we are sure to be gross, sweaty and smelly. However, if you have an abundance of oatmeal stocked up, you can always use it to wash yourself. It makes a great scrub, plus it is moisturizing and calming. You can even use it on poison ivy stings.
Honey - Great source of energy, loooong shelf life (archaeologists have found pots of honey from Egyptian tombs that were still edible), antibacterial and anti-inflammatory. Great item for helping to heal wounds.
Baking Soda - Anti-acid, deodorant, teeth whitening, face & body scrub, mouthwash, relieve skin irritations and the list could keep going and going.
Tea Tree Oil - Anti-fungal, Antiseptic.
Coconut Oil - Great source of energy and makes a great hair conditioner.
