Skin Irritation from a Liquid

  1. Mar 31, 2005 #1
    This is sort of an unusual question (and I'm not even sure this is the right forum for it) but here goes. I'm doing a project where theoretically a human would be kept immersed in a liquid for long periods of time and I'm wondering what liquid would be the best for this. The most obvious choice would be water, but long term exposure to water causes skin irritation because water removes the surface layer of oil off the skin that normally locks in moisture so when the person got out of the water the skin would feel extremely dry. I'm curious if anyone knows of a liquid, or maybe a gel-like material, that doesn't cause this and is safe enough for direct contact with skin for extended periods?

    Sensory deprivation tanks use an Epsom salt solution in water. People float in sensory deprivation tanks for hours:

    What effect does salt water have on my skin and hair?

    The Epsom salt solution seems to be beneficial to the skin. We have listened to some opinions that say Epsom salt is very good for strengthening the hair. We know it's good for roses, why not hair? You thoroughly rinse the salt from your hair and body when you leave the tank.

    Also the primary moisturizer in human skin is NaPCA. You can buy it at Beyond A Century and apply it when you get out of your sensory deprivation chamber.

    Water immersion wrinkling--physiology and use as an indicator of sympathetic function.

    You can try vinegar, it would most likely irritate the skin due to it's acid content. Or maybe sulfur enriched water, so as that from a geyser (cooled off of course :p)

    I would just use Aloe. It's definately safe for your skin, you can even eat the stuff, and you get to be all green and gooey, which is generally a bonus.
