Xanthan Gum is an effective thickening agent and stabilizer to prevent ingredients from separating.
Only a small amount is required between 0.1% and 2% of the solution you are trying to thicken. The easiest and most effective option is to blend Xantham Gum with Glycerine and it will make a paste that can be easily dispersed into water.
Xanthan gum is produced by natural fermentation of corn, soy, wheat, or cabbage. The bacteria digest the sugars in these vegetables and produce a complex sugar polymer. Alcohol is added to make it drop out of solution. The xanthan gum is then dried and converted into a powder that can be used in food and other products.
