Checking for Stabilizers in H2O2
★★★★★
Almost all H2O2 sold in drug stores will have stabilizers, actually to discourage people to use them internally. So you can use this as a way to compare them. Basically, hydrogen peroxide poured into a clean glass and left out in a sun covered by a dish should not have air bubbles. If it does, there are metal contaminants. If you are asking for trouble, a drop of ammonia solution in H2O2 mixed in water will cause a rapid air bubble generation. It is more unstable if it has stabilizers. You can try the experiment and compare the results.
The test for this is not perfect one, but the key is the color, even when you add just a small amount of water in direct sunlight. Also, a good quality H2O2 doesn't get small bubbles during storage.
By the way, an easy way to test the quality of your drinking water is to add 10% of 3% H2O2 to 90% Water and perform the test by noticing air bubbles. If there are a lot of air bubbles for the next 6 hours, then the water has either too much organic residues OR heavy metals. During the test please keep in places AWAY from children. After the test immediately discard the contents into the sink. Ted"

I went to Wal-Mart to purchase some HP and when I got it home I noticed that my bottle of HP had the skull and cross bones on the front of it. Yikes!! The lable reads "POISON" because this particular brand contains stablizers. The previous brand that I bought did not have stablizers in it and did not have the skull and cross bones symbol on the front. I dont't think I want to try to ingest the poison type of HP. I think readers should be made aware that there is a difference and to be careful when buying HP, to make sure they find one without stablizers."
09/17/2007: Ted from Bangkok replies, "Remedies require food grade H2O2 except in instances of external use. H2O2 can't be labelled poison if it is for external use (as in antiseptics) since other contact poisons go directly through the skin killing you. Stabilizers can't do this. Most labeling no longer uses the skull and bones, at least not on H2O2, since hydrogen peroxide more often causes skin burns only if used in high concentration and are classified as caustic solutions. Even hydrochloric acid might also be considered a poison, but our stomach produce plenty of it. I don't think labels are consistent in classifying it"
