Why did I buy that again" Siligel
This is a neat new gelling agent that's considered green, eco-friendly, and natural. Siligel (INCI: Xanthan Gum (and) Lecithin (and) Sclerotium Gum (and) Pullulan) can create gels, be used as a stabilizer in emulsions, suspend things like exfoliants in gels, and enhance skin feel. (They say it may be a substitute for silicones.)
It comes as a water soluble beige powder that we use anywhere from 0.3% to 2% depending upon the application. It has a 12 month shelf life, and it's hygroscopic, meaning it can draw water to itself so keep it well sealed with a few silica packages for good measure.
It can tolerate quite a lot of electrolytes at up to 20% - you'll see this shortly as I used it with magnesium chloride - as well as up to 15% alcohol. You can use it in facial products in which you might want to add hyaluronic acid, AHAs like glycolic acid, or salicylic acid as it can handle a huge pH range of 2 to 10. It can handle up to 2% oils, but it's not a great emulsifier.
The down side is that it can't really be used with more anionic surfactants (negatively charged) or amphoteric surfactants (like cocamidopropyl betaine) at more than 5% active matter or cationic ingredients, like Incroquat BTMS-50 or a cationic polymer, like Honeyquat or polyquat 7. It can be used with decyl glucoside and other non-ionic surfactants, like polysorbate 20 or 80 and caprylyl/capryl glucoside. (Remember to alter the pH there!)
It can take up to 24 hours to reach its final viscosity, so...
