This has been a recent topic of discussion in my International Travel News newsletter. One traveler wrote in that he deals with the problem of liquids, gels and pasts by not carrying any of them.
Dann Halverson of Houston, TX gets a big Thank You for providing the following information.
Shampoo: J.R. Ligett's solid shampoo
Shaving Cream: uses the solid shampoo
Toothpaste: Daily Care Toothpowder
Face Cream or Lotion: Use Dove body soap instead
Laundry Detergent: Scent Killer laundry powder available at outdoor stores like Bass Pro Shop
Body Powder: Scent-A-Way also available at stores like Bass Pro Shop
The above two items, as Mr. Halverson notes, are meant for hunters ... he figures if the deer can't smell the hunter, then the person traveling next to you won't smell you either.
