"The FDA granted clearance to Oculus, Inc. for the use of their stable Microcyn
superoxidized water wound care system:

Hoji Alimi, founder and president of Oculus Innovative Sciences, today
announced that the company has received its first 510K clearance from the U.S.
Food and Drug Administration to market Dermacyn(TM) Wound Care, formulated with
Microcyn(TM) Technology, as a medical device for moistening, lubricating and
debriding of acute and traumatic wounds and burns.

Microcyn(TM) Technology is a super-oxidized, pH-neutral solution that is
ready for use with no dilution or mixing, and requires no special handling or
disposal. It is manufactured using a sophisticated, multi-chamber electrolysis
process in which ionic species are selectively produced and isolated. This
process allows for the production of a pH-neutral solution while minimizing the
level of chlorine in the final product. "

"The FDA granted clearance to Oculus, Inc. for the use of their stable Microcyn
superoxidized water wound care system:

From their web site:

"Microcyn technology is a pH-neutral, super-oxidized water that
contains oxidizing species generated by the electrolysis of sodium
chloride and water. During this patented multi-chamber
electrolysis process, these molecules are pulled apart and ions
are formed."

In other words, ordinary laundry bleach. A description is given here:

-------------------------------------------------------------------

http://www.chem1.com/CQ/ionbunk.html

Some "water ionizer" devices depend on the presence of ordinary
salt (sodium chloride, NaCl) to make the water more conductive.
Electrolysis of a salt solution yields chlorine at the positive
electrode because Cl- ions lose electrons more readily than H2O
molecules; in this case the overall reaction yields an alkaline
solution:

2 Cl- + 2 H2O --> H2 + Cl2 + 2 OH-

but as noted at the bottom of the diagram, if the products of
electrolysis are allowed to combine, the result is a dilute
solution of hypochlorous acid, HOCl. This weak acid is a powerful
oxidizing agent and disinfectant, and is the active disinfecting
agent in chlorinated drinking water.

In the presence of sodium ions (required to maintain
electroneutrality), the resulting solution is known as sodium
hypochlorite. This is the main ingredient of ordinary household
bleaches such as Chlorox. To characterize such waters as
having"antioxidant" properties is incorrect; both HOCl and OCl-
(hypochlorite ion) are quite strong oxidizing agents.

------------------------------------------------------------------

There are many similar products on the market. This one shows the
electrolysis process:

HOW STERILOX WORKS

Sterilox solutions are produced by a unique, patented electrolytic
cell

Often referred to in the past as super-oxidized water, Sterilox
solutions are produced by the electrolysis of brine solutions. A
proprietary electrochemical cell is controlled by a patented
process and contained in a series of proprietary generators. It
produces a dilute mixture of mild oxidants at nearly neutral pH
from the brine solution. The primary active ingredient in the
product stream is hypochlorous acid, an extremely powerful
high-level disinfectant that is non-toxic at the low
concentrations necessary for high-level disinfection with Sterilox
solutions.

The Center for Disease Control has a short description:

CDC - New Disinfection and Sterilization Methods

A New Disinfectant: Superoxidized Water

The concept of electrolyzing saline to create a disinfectant is
appealing because the basic materials, saline and electricity, are
cheap and the end product (water) is not damaging to the
environment. A commercial adaptation of this process, Sterilox, is
available in the United Kingdom. The mode of action is not clear
but probably relates to a mixture of oxidizing species. The main
products are hypochlorous acid at a concentration of approximately
144 mg/L and free chlorine radicals. This disinfectant is
generated at the point of use by passing a saline solution over
titanium-coated electrodes at 9 amps. The product generated has a
pH of 5.0-6.5 and an oxidation reduction potential of >950 mV.
Equipment to produce the product may be expensive because
parameters such as pH, current, and redox potential must be
closely monitored. The solution has been shown to be nontoxic to
biological tissues. Although the solution is claimed to be
noncorrosive and nondamaging to endoscopes, one flexible endoscope
manufacturer has voided the warranty on its endoscopes because
superoxidized water was used to disinfect them (12).

The antimicrobial activity of this new sterilant has been tested
against bacteria, mycobacteria, viruses, fungi, and spores
(13-15). Recent data have shown that freshly generated
superoxidized water is rapidly effective (<2 minutes) in achieving
a 5-log10 reduction of pathogenic microorganisms (Mycobacterium
tuberculosis, M. chelonae, poliovirus, HIV, MRSA, Escherichia
coli, Candida albicans, Enterococcus faecalis, Pseudomonas
aeruginosa) in the absence of organic loading. However, the
biocidal activity of this disinfectant was substantially reduced
in the presence of organic material (5% horse serum) (14).
Additional studies are needed to determine if this solution may be
used as an alternative to other disinfectants.

Sounds very similar to the results from ordinary laundry bleach!

Chlorox bleach. More diluted, less salty, with pH adjusted close to
neutral. Normal alkaline bleach would be bad for wound healing.

Their description is pure salesman goobledygook - bleach use for
disinfecting wounds is not patentable so they have to dress up their
"proprietary technology" in fancy words. If you look up the active
substance declared in their FDA submission, you see "sodium
hypochlorite and hypochloric acid."

At least that means it is not a snake oil - I suppose that's what
attracted Dirk attention. "super-oxidized, pH-neutral solution" -
they only didn't mention they use water particles smaller then
normal Smile)))
