Much maligned ingredients week

When this series on preservatives ends on November 4th, I'm planning a week of much maligned ingredients week, including propylene glycol and mineral oil, and some of those on the Suzuki Foundation's list. Since I tend to be out of the loop about what's bad this week, I'm looking to you - my amazing readers - to let me know what concerns you! Comment below on what you'd like to see researched!

I have an idea in mind but will hold it till you talk about my hero- the completely "synthetic"!! cosmocil. (I just love saying poly amino propyl biguinide!)

I swear though, sometimes I just want to add about 5 tablespoons of salt and an oz of vodka, just for simplicities sake, and yell out my window- There's your preservatives flowerchild! Now sit 10 mins with the engine running in a drive thru, eat non organic strawberries (highest pesticide agriculture), buy plastic bottled water- daily, eat bread(highly processed- yeast, baking= fuel aka ghost of carbon's future... But I digress.....

Sorry :)

Hurdle technology? Yeah, hurdle of teaching common sense cosmetics to the nuts......

Keep up good work!

I'd be interested in hearing about alternative ingredients for people with allergies. For example, sweet almond oil and soy-based ingredients come up a lot, and nuts and soy are two of the more common food allergens.

Great idea! From that Suzuki list, I'm interested in the claims about PEGs, which I've heard before but from similar sources, which makes me skeptical.

I'm interested in claims about deodorant ingredients. I'm still not sure about aluminium - I know most claims are alarmist, but apparently there is also proof that people with renal conditions can't eliminate it, so I'm wondering if it's best avoided for those of us with other health conditions.

Beyond this, I hear claims that anything antiperspirant interferes with toxin elimination through sweat - which more credible sources say is BS, but I would love to hear about why exactly it's BS.

One natural cosmetics company even says in their FAQ that if you start to stink after switching to their deodorant, it's only because at first you are 'detoxing'. (They literally state, if you use our product, you will start to detox... is this even a legal claim?)

I'm also wondering about how bad fragrance really is for the skin. I don't use it at all due to sensitivity, but Paula Begoun believes it's not something we should never put on our skin. She says it's an irritant which will cause damage even if we don't get an obvious reaction.

^ correction: *it's not something we should EVER put on our skin.

Hi,

I was wondering about propylene glycol. I've heard that it is suppose to break down the skin's natural barrier system so that nutreints can be absorbed more readily. unfortunatly it would also make our skin vunerable to toxins because they will also go through. I was just wondering if that was true? This ingredient is in "everything"...well almost anyway. What's your take on the subject?

My first post in this series is in propylene glycol (look for it on the 6th). I can assure you it doesn't break down our skin's natural skin barriers, although it is a penetration enhancer for other ingredients. Our skin is remarkably good at resisting toxins - think of all the things that could hurt us every day and they don't penetrate our skin (viruses, bacteria, and so on) - and using propylene glycol won't you more vulnerable to anything!

I wanted to here about extracts. I have seen their inci in many many different ways. But how about the ones that just say, for example "grean tea extract". What is an extract? Or is every extract different? Thanks!

I have a whole section of the blog on extracts and a PDF you can download about green tea. I'm not really sure how this fits into maligned ingredients because I don't think there's really a controversy about green tea. Most people seem to like it.
