Just a wee quick post about a little test I did last week with three different gums: xantham gum, guar gum and carrageenan gum. These are used to thicken waters into gels, but as you’d expect, they don’t all give the same results.
The reason for doing these tests is that I have this idea for creating an under eye gel, specifically for puffy eyes. Don’t you just hate it when you wake up in the morning with these puffy rings under your eyes? I sure do. And although you could put cold tea bags on your eyes to get rid of them, seriously, who has time in the morning to drink two cups of tea and then wait for the bags to cool down? Besides, I’m a coffee drinker!
So here I am testing gums for my under-eye gel. I tested the three gums using the same ingredients and gum-to-water ratio:
93% cucumber hydrosol
My favourite so far is the xantham gum. It has the best gel-like consistency and is the thickest of the three. The other two are much runnier (carrageenan is the runniest at this ratio).
Transparency and colour, guar is slightly clearer than xantham, but it’s hardly noticeable. Carrageenan, as you can see in the picture, has a light yellow undertone to it.
Colour also is very dependent on the hydrosol you are using. For example, I noticed neroli hydrosol also results in a yellow tinge.
Best tip I learned from Formula Botanica this week: mix your gum with glycerine first, before adding the hydrosol to it. Otherwise, you’ll end up with a lumpy gel!
