Are any of these ingredients humectants?
 
I've been using the Walgreen's brand AVG as a leave in and was getting great results for the past few weeks. Lately though, I've been getting a lot of frizzy and loss of definition. I'm not sure if the AVG is the culprit but the weather has been very cold here lately and I know that humectants can be drying in cold weather. I was wondering if any of the ingredients in the AVG are humectants.

These are the ingredients:

Aloe Vera Gel , Triethanolamine , Tocopheryl Acetate , Carbomer 940 , Tetrasodium EDTA , DMDM Hydantoin , Diazolidinyl Urea

What do you think?
Thanks!

Aloe Vera is considered an humectant or "water-binding agent". Diazolidinyl Urea is a preservative and Triethalomine is a PH balancer.

We just had another conversation about this very thing, and Jillypoo says aloe vera is not a humectant... http://www.naturallycurly.com/curlta...19962#poststop

I don't know what her source is, but I checked out your link (which is awesome, by the way!), and it does list aloe vera as a "water-binding agent," which, according to the same source, is synonymous with "humectant."

Nowhere does the CurlChemist list aloe vera as a humectant, which seems like a gross oversight if this is the case. (See http://www.naturallycurly.com/curlre...tants-and-hair and http://www.naturallycurly.com/curlre...are-humectants)

I think this is kind of a big deal. :( I've been using aloe vera gel under the impression that I was imparting more moisture into my hair!! If I find out it's a humectant after all... I'll be very disappointed.

Aarrgh! This stuff is so confusing! I will try to leave it out for the next few days and see if it makes a difference.
Btw, Afrosheenqueen, thanks for that link. Great info!

I think part of the problem is the various uses of the word humectant itself. It's often used in different ways, to mean anything from "moisturizing", to "attracting water" which to me are contradictory, one implying that it gives moisture and the other that it takes moisture up.

I can't find them right now (I'll try to track them down when I have more time), but a couple of the study results I've read about aloe refer to its polysaccharide content as preventing moisture loss. There are different types of polysaccharides and they are not the same things as disaccharides (like honey or agave nectar are comprised of) since they of course have a different structure and may not attract water molecules in the same way that disaccharides do.

As complex polymers, with a different structure that the disaccharides or glucoses that comprise them, I think they would be more like film-formers. I've seen the polysaccharides in aloe referred to as mucilaginous polysaccharides which seems significant to me. So since aloe juice/gel is itself 99.5% water, I've taken that to mean that rather than attract water to itself like a true humectant would do, it forms a film once dried. Since we're putting it onto hair which is naturally porous to a certain extent, my understanding is that the hair absorbs the aloe's water content and consequently that moisture is bound inside by the film that is formed as the aloe dries. Not that the aloe itself attracts moisture from other sources.

Of course, I could be totally wrong. :D :p I do wish our Curl Chemist would join in...

I really appreciate the info! We really do need some of our chemistry pals to show up!

I've never considered Aloe Vera a humectant myself but I'm having too many up an down days with AOMM to be sure now. Its nothing but AVG and herbs. I personally think its moisturizing but not water attracting.

I think Paula's site gives very good information. More inclusive than anything found on the internets beside this one that uses info from the FDA. http://www.cosmeticsinfo.org/index.php

I use both to bounce information off of each other. I also don't see anything wrong with silicones. There are not the devil. If your on the CG routine though they can build up big time which is why you should avoid them.

This is great, Koukla! I could have saved myself some typing in another thread by just directing people to what you just said! The most cogent description I've yet to read about what aloe vera does. Thank you very much!

You are much too kind. I should actually link from my blog to what you wrote!

But really, I agree with redcelticcurls who said in the related post that these nerd posts are just the best. There is so much information out there that eludes those of us who aren't scientists... When we get a little piece of it, we feel like we've cracked a secret code or something.
