Interesting thread. It reminds me that I was going to post about something related and that is the use of natural crystal deodorants.
I had always used bog standard non perfumed underarm deodorants but my brother persuaded me to try a small piece of some natural mineral salt crystal instead during the summer hols. Personally I was pretty sceptical and not the 'crystal' type
Basically it is a naturally occurring alum crystal he brought a great big lump back from Morocco (no not black sticky stuff
) which he has used for years and swears by it.
Natural crystal
Lots of products
I had read about how normal deodorants work by blocking your pores to stop sweating and thus the BO associated with it. I do not like the idea of using chemicals unless necessary or blocking up pores etc so I gave it a shot.
After only a few days I was pretty amazed. It felt a LOT more healthy, I sweated more freely which was a bonus in the hot weather but the normal BO smells were really reduced, (not that I really smell normally just that after a couple of days most people start to pong). So after 5 months I use this crystal twice a day after a quick wipe down to remove build up of body salts. If water is tight I just use the crystal slightly moistened to allow it to be applied. I use a reasonable chunk normally and a smaller bit for outdoor use. It weighs only around 20-30 gms and keep it in a small plastic zip bag.
I am sure a lot of people here know more about them than me and have more experience using them. I can say they are defintiely not just for tree huggers
If you lick your finger with some on it has a slight acid taste. This kills the bacteria which cause BO but does not block the pores so you can sweat naturally. I also thought to try a wipe as a control of crotch rot and it really worked too! Given the slight acidity you don't want to get it on cuts or grazes as it stings and as with any skin product I guess you are best trying it in a small patch first.
I may well try it out on my feet next (rubbing in hands then applying) as a natural alternative to Mycil. I have seen it advertised for feet use and you can get a powdered version which you use like Mycil.
From my experience as an initial sceptic, I would say they are well suited to outdoor use or normal use everyday.It would be interesting to hear if other people use these. You can buy them in a lot of places now and they are not too expensive (you can get all kinds of prepared ones but natural ones are fine and cheaper. for example £5.35 for 60gm piece) and last a long time. Easy to carry etc.
I found some detailed info on them:
Deodorant Stones are Natural - Key Points to Remember
Alum is a natural compound in nature, is present in the water we drink, in almost all the foods we eat, and in the air we breathe. According to a study conducted at the University of Wisconsin, the average American adult diet includes between 20 to 60 milligrams of alum per day, of which 20 to 50 milligrams come from FDA-approved food additives. Another 2 to 10 milligrams come from the natural content of the foods eaten.
In its natural form, alum is the third most abundant element in nature, after oxygen and silicon. It has been part of our environment since the beginning of time and is one of the basic building blocks of our universe. It makes up almost 8% of the earths crust, surpassed in quantity only by oxygen at 47% and silicon at 28%. It is in soil and clays that only when processed produce metallic aluminum products.
Deodorant Stones feature physically large potassium or ammonium alum molecules and are not absorbed into the skin/blood. Water has a molecular weight of 18. A potassium alum crystal molecule has a molecular weight of 474.38. A potassium or ammonium alum crystal molecule, in solution, is hydrated 24 times and consequently has a molecular weight of 654. It is impossible through natural means to get water to permeate the skin. Witness the large number of moisturizers available at the cosmetic counter and imagine how difficult it would be for a molecule that weighs 36.3 times as much as water to permeate the skin.
The pH of the solution resulting from the topical application of potassium alum with perspiration is typically in the slightly acid range of 4 to 5.
