Solubilizers: Caprylyl/capryl glucoside

I wrote a bit about this solubilizer caprylyl/capryl glucoside in this post on glucoside surfactants, but let’s learn more about it now!

Caprylyl/capryl glucoside (aka octyl/decyl glucoside or C8-10 alkyl polyglucoside) is an Ecocert non-ionic solubilizer with a pH of 5.5 to 6 that can be used as a solubilizer and a very gentle surfactant. It comes to us as a 60% active ingredient product, and the suggested usage is 1% to 10%. It can be used in our surfactant based products to increase viscosity and boost foaming, which is always a bonus, and it can also be used as a very gentle surfactant in things like make-up removers. It may be compatible with liquid soaps, but I haven’t had a chance to experiment with that. (If you have, let me know!)

“Decyl glucoside is produced by the reaction of glucose from corn starch with the fatty alcohol decanol which is derived from coconut(s).” (From Wikipedia) Both Voyageur and The Herbarie note that it is of vegetable origin, but there isn’t a specific origin noted. It is considered to be biodegradable and created from a renewable resource. As I mentioned, it’s also Ecocert. And as I’ve seen it called natural all over the web, I think it’s safe to call it that.

If you want to use it as a solubilizer to add oil based products to a water based system, there isn’t a hard and fast rule about how much you’ll need. I generally start with equal parts of the oily ingredient to the solubilizer. So start with 1% fragrance oil to 1% caprylyl/capryl glucoside and see if that gives the results you want. If it doesn’t, go to 2:1 solubilizer to oil and continue on until you reach 10:1 (although if you need that much, you might want to consider another solubilizer!)

As an aside, this is something I found on Clorox’s website about this ingredient: “Caprylyl/capryl glucoside (also known as octyl/decyl glucoside or C8-10 alkyl polyglucoside) is a mild surfactant used in household and commercial cleaning products. It is known for its foam boosting ability, lack of streaking, easy rinsing, and is ideal for glass cleaners.” And this from this website about decyl glucoside: “APGs are very suitable for hard surface cleaners, such as bathroom cleaners and glass cleaners because of their excellent hydration, little water spot and little residue.Because of its strong tolerance to strong alkali, APG is very important in preparing high alkaline industrial cleaners.” 

I regularly see people condemning ingredients like SLS or propylene glycol because they are used in commercial cleansers…It isn’t looking good for caprylyl/capryl glucoside if that’s how you determine what ingredients you’ll use. Having said that, I’m trying this in a glass cleaner for my car! I’ll step off my soapbox now…

Join me tomorrow for more fun formulating with caprylyl/capryl glucoside!

As a note, there’s a great discussion that happened on the original post on the old blog, so I encourage you to check it out!
