Quat-80 + Fatty Alcohol
Hello all!
I’m an undergraduate intern at cosmetic chemistry company researching the effects of Quaternium-80 when combined with a mixture composed of a specific potassium salt derivative (soap), and a fatty alcohol. The research has shown that, when combined with Quaternium-80, this mixture is more substantive to keratin fibers than when mixed with any other quat/polyquat (that my company has on hand, anyways). I’m trying to figure out why that is.
From the scraps I’ve been able to collect from searching scholar/google/WOS/etc, Quaternium-80, or, dimethyl, 3-[3-[(3-coco amidopropyl)dimethylammonio]- 2-hydroxypropoxy]propyl may take part in an alkali-silica reaction? I can’t seem to find a mechanism if this is, in fact, the mechanism responsible for the improved substantivity.
I also read that when marrying fatty acid chemistry with silicon chemistry, it results in “unexpected solubility and surface active properties,” but whether “unexpected” connotes to “improved” or not is left at that.
At this point, I thought maybe someone from this community could nudge me in the right direction. I’m willing to provide additional information if necessary!
Thank you all so much.
