“I’ve had a wonderful day today explaining to the fluffy bunnies about the joys of Crystal Deodorants.
I’ll admit they look quite cool in a rustic tree huggy sort of way. The trouble is that tree huggy products come along with tree huggy vendors who don’t always understand the nasty technical details. A prime example is here, but it is echoed across the web. I’m a chemist. I like things to be basically right Warning BS Alert
If you can’t bear to give them hits, I’m doing a step by step below
“It is a pure, natural crystal of potassium alum, (nothing to do with aluminium) formed from non toxic minerals in mother earth. It is hypoallergenic and has been used for centuries“
Hmmm lets see. Google for a MSDS (Health and safety data sheet) for potassium Alum This was the first one found Courtesy of JT Baker a chemical supply house in New Jersey Well its Potassium ALUMINIUM Sulphate. That says to me thats a lot to do with Element 13. Also hypoallergenic may be a bit strong considering the pH of a 0.2M solution in water is 3.3, and it is described as an irritant, though to be fair most roll on Anti perspirants based on Aluminium Chlorohydrate are much the same.
If they’ve done the testing and it comes out hypoallergenic I’ll let that lie
“1) A natural anti-bacterial action within the crystal eliminates the bacteria that causes odour.
Well its acidic and sits on the skins surface …..(Just like proper FDA approved Anti-perspirants that give you cancer)
2) On application a little of the crystal dissolves and sits on your skin’s surface as an invisible microscopic protective film, eliminating odour for 24 hours or until you next wash.”
(Just like proper FDA approved Anti-perspirants that give you cancer)
3) The crystal’s molecular structure is too big to pass into the body. This means your pores are not blocked as with anti-perspirants. Instead your body’s natural processes continue to operate but without the associated odour.
(Just like proper FDA approved Anti-perspirants that give you cancer, but with a twist).
Alum is not approved on the FDA monograph, as it really isn’t quite up to snuff, performance wise
Next two sections I shall ignore as they are hints for use. Thats up to the consumer to be honest
Now lets see
“What is NOT in it (and often found in other deodorants):
1) Perfume (Bit difficult as you would have problems dissolving fragrance oils into a solid block) Unfragranced is a relevant market strategy
2) Preservatives (An effective deodorant inhibits bacteria on the skin. they rarely require preserving)
3) Emulsifiers or oils (As contained in the finest Creams and moisturisers)
4) Aluminium chlorohydrate – linked to Alzheimer’s & breast cancer (I’m not going to justify this). The FDA mandate that the warning “Ask a doctor before use if you have kidney disease” is put on pack, but this is to do with concerns about putting Aluminium anywhere near anyone with renal Failure. Google the phrase “Dialysis Encephalopathy” for information. Basically people with kidney problems are likely to suffer buildup of Aluminium in the system. It can cause problems
5) Parabens (linked to breast cancer) See the previous post on this blog for that
6) Anything that may stain your clothes (If you’ve done the stain tests….)
Time to take a stand. The ASA has hit 3 cosmetic companies this week. Prehaps that should be four
