Clorox going green?

Most if not all of you have probably seen these products advertised by Clorox, the new GreenWorks line. They are touting it as a "natural" cleaner, safer for the environment and the user, etc. etc. etc. Most of you may also know that my background is in chemistry, and today I had a few minutes to take a look into the ingredients of these "natural" cleaners. I add the quotes, because the word natural as it is used by corporations is a completely unregulated and VERY loosely used term. OK, so what's the verdict, is it natural or not. Well we will get to that shortly, first let me just list to you the ingredients per their labels:
water, alkyl polyglucoside, ethanol SDA-3C, glycerine, lemon essential oil, preservative (Kathon) and colorant (Milliken Liquitint Blue HP dye and Bright Yellow dye X) and also some of them contain sodium lauryl sulfate and lauramine oxide.

Now a good general rule of thumb with these sorts of things is, if you can't tell right away where something comes from, then it probably isn't natural. Alkyl polyglucoside??? Turns out is pretty readily available from chemical manufacturers such as Dow. Clorox says that it is derived from Coconuts. OK then. The use for this surfactant (which basically means a wetting agent that lowers the surface tension of a liquid) is to help form nice soapy bubbles and act as the main detergent ingredient. This is basically the meat and potatoes of the cleaning product. The other stuff is added for smell, color and preservation. So what exactly is it? well it is a synthetically produced chemical. It does appear to degrade pretty quickly (28 days) I do not know the path to degredation though, so I have no idea why it doesn't just break down in the bottle, most likely what the preservatives are preventing, as well as the prevention of bacterial growth. Dow says they are quite stable in a caustic environment, meaning pH higher than 8 or so, which is common for soaps and cleaning products.

The other eyebrow raisers; Sodium Lauryl Sulfate, Lauramine Oxide (an emulsifier, meaning it allows oil and water to be mixed). could both definitely be construed as very un-natural and SLS sounds downright scary. The others, preservatives and dyes.. eh.. Then you have corn based ethanol, which I don't have a problem with using in a cleaner personally, but there is the little problem of the creation of that ethanol taking up huge amounts of energy both in production and in the transport of corn, etc.

Anyway, about the only thing truly natural in this bottle would probably be the water, the rest are synthetically extracted or produced wholly in a lab. I think I'll just use some vinegar and water...

Six Degrees Could Change the World

I watched this last night, and I just have to say that it is a MUST watch for really anyone. Not just the people like me that are obsessed with the planet, but even the sceptics among us. I really encourage anyone to check it out and the webpage if they get a chance. It is far superior to the horribly dumbed down special that CNN put together a couple months ago. This one gets a bit spectacular with the visuals, but by most accounts they are being pretty conservative with the predictions.

It is pretty scary stuff. We all know the troubles we could be in if nothing is done, but unless something really big happens soon, we might as well all invest in the future breadbasket of the world in north-central Canada.
