shokubutsu

I just bought a refill pack of shokubutsu(tm of Lion Corp Japan) Orange and seaweed shower foam (love the smell) which the package says, contains "100% cleansing ingredients from plants"

So out of curiosity, I actually read the ingredients list (anyone here ever read the ingredients list on product packages and is able to make sense of it? heh that's what chemistry can do for you...)

So here's the list: Water, Myristic Acid, Propylene GLycol, Lauric Acid, Potassium hydroxide, Lauramine Oxide, Steareth-11, Acrylates Copolymer, Fragrance, Orange Peel Oil, Algae Extract, Hydroxypropyl Methylcellulose, Polystyrene, Tetrasodium EDTA, Bentonite.

Heh I can set a whole chemistry paper just from this ingredients list(does it look "100% plant extract"?), but I'd like to ask you a question:

What do you think the tetrasodium EDTA is for?

clue: this question can be answered by some concepts you will learn from your next(after next) topic, transition elements.


cheers :)

p.s. and (please), never believe in hoax chain mails about cancer causing "SLS" in toiletry products blindly; go study your chemistry first!

Hello!!!

Hi all!!

This is a new blog specially set up by rjc's chem dept for you. It'll be a great way to facilitate communications, for example, to make announcements (students keep bugging us for details of announcements already made in lectures and on notice boards >< ) , and FAQs etc.

I'll get around to doing up the relevant sections like a tag-board and a counter.. that'll be up soon... firstly we gotta get CT2 out of the way :)

cheers
