That doesn’t happen with high CAPB, low glucoside. -
@Gunther exactly! I add a tiny amount of decyl glucoside to boost the foam but I didn’t know its used as a primary surfactant. It’s however considered quite mild based on zein test.

Both via anecdotal evidence and studies, Decyl Glucoside is hardly non-irritating. https://www.jaad.org/article/S0190-9622(17)32539-2/fulltext

Any ingredient is going to have some subpopulation that will have some sort of sensitivity to it … look at is this way … 98% to 99% of the population don’t have any sensitivity to Decyl Glucoside.
-
Yes, but in my anecdotal experience, I have seen 5-6 lines in the last 3 years move away from the alkylpolyglucosides. @Belassi has experienced this as well if you followed some of his relevant posts.

Well, There’s Science and then there’s Anecdotes … The Science says that 98% to 99% of the population do not have any sensitivity to alykylpolyglucosides.

I understand the differences quite well.The issue is simply that the bias against these products is growing. I get approached about once a quarter now from lines that want to respond to the bias and reformulate.My key point was to dispute that it is considered “quite mild.” I believe that I have made a great case that this is not necessarily the case.
-
I personally don’t like glucosides. Especially for hair products (that is why my question was “why decyl glycoside”). The reason why I said it is considered to be mild is a result of zein test according to which it can be classified as mild comparing to other surfactants (such as SLS, SLES). The result of zein test isn’t 100% proof but it is a piece of scientific evidence. I didn’t mean that there are no people (and animals?) who are sensitive to it. I don’t have experience with animal products but my first guess would be CAPB, not decyl glucoside.
-
Actually, decyl glucoside ranks a bit milder than CAPB … but I’m sure not appreciably enough to make much of a difference unless someone is predisposed to an contact reaction to either one.
-
Decyl Glucosdie actually is mild, that what the science proves. As for companies reformulating … well, who wants “Allergen Of The Year” on your label … that is probably more for marketing purposes than anything.
This “Allergen Of The Year” competition is quite dangerous … you can see several ingredients that are perfectly fine for 99% of the population fall out of favor based on these kinds of articles. Look at what happened to parabens.
-
Just to be clear, my own opinion is that glucosides are OK in rinse-off products in reasonable concentrations. I can’t abide its use in a leave-on product though.
-
All good points.

It’s a tree from the fam. Polyquaterniumeae. :smiley:

@ngarayeva001 - This is why I contend that everything is natural. And this will be true until someone can prove the supernatural exists.

Agreed
