I like Karen's answer. H2O+ is the free radical of water.
It is not useful in beauty produces.

Subject: Re: [TN] H2O+
My first thought was H2O+ is an ion that would be generated in a mass
spectrometer with water as a sample. I looked up - H2O ion radiation -
on Google and got better links. Strong radiation can kick an electron
off
a water molecule, leaving H2O+, a reactive free radical, i.e. a molecule
with an unpaired electron. Unstable free radicals will quickly react
with
other molecules, and this can have deleterious effects on living
organisms.
The H2O+ in beauty products just means the product contains humectants,
chemicals that absorb and retain water, such as glycerol. Retained
moisture improves the appearance and texture of skin and hair. H2O+
radicals would have the opposite effect.

Please respond to TechNet E-Mail Forum, "Stadem, Richard D."
I have a technical op sheet that deals with E-beam irradiation for space
product that will enter the atmosphere or land on a planet other than
ours,
or will re-enter our own atmosphere after having been elsewhere. In
order
to meet Planetary Protection standards we do the irradiation.
In the document, it describes collateral byproducts of the irradiation,
all
of which I understand except the term H2O+ . When I tried to look up
H2O+
all I could find was beauty products. Does anybody know what H2O+ is,
from
a chemical standpoint?
