Coco Glucoside with lower water content?
I would like to incorporate Coco Glucoside in a “self-preserving” formula that I’ve been developing. All the Coco Glucoside I have found for purchase is normally at about 40-60% concentration, with the rest being water. If I could change that ratio to 80% CG / 20% water or ideally lower this would help a lot.I am tempted to just boil the water off a small batch to see what happens, but then I’m thinking there must be a reason that I haven’t seen waterless Coco Glucoside for sale.So my question is, is there a chemical reason why Coco Glucoside can’t exist without water? And what would the lowest water percentage that one could buy/achieve through modification? -

Yup: without water as diluent that surfactant is a gummy mess.

Very interesting, thank you! I’ll have to see if I can work with gummy. At least I don’t seem to be pointlessly trying to break a chemical rule (thinking of the obvious impossibility of acidic shampoos containing soap for example).I did a small test with some Coco Glucoside in a fan oven for 3 hours at 50°C, which reduced it to 70% of the original amount. My starting batch had 55% Coco Glucoside, so assuming mostly water evaporated, I should be left with just about an 80/20 ratio. At 50°C it’s less viscous than the original product at room temperature, but I’ll wait to see what happens when it cools down and will try to work with it tomorrow.Edit: I just tested a bit of the very gummy scrapings from the sides of the container (near 100% CG?) and some of the presumed 80/20 mix, just washing my hands with them. The lather seems hard to work up and very fine/creamy.
