Xanthan Gum is a natural gum polysaccharide created through fermentation of sugar (glucose or sucrose) by Xanthomonas campestris bacteria. Xanthan Gum is used as a food additive, and in cosmetics, as a thickener or rheology modifier and emulsion stabilizer. Xanthan Gum produces a large increase in the viscosity of a liquid with the addition of a very small amount of gum. Generally 1%, but as little as 0.1% can be used in many applications. Xanthan Gum is an excellent natural source thickener for lotions, creams, liquid soap, shower gels, body washes and shampoos.

Xanthan Gum Clear is a higher purity, cosmetic grade made without hydration retardants for quicker thickening. It produces the clearest gels.

Please Keep Your Products Out of Humidity, Heat, Direct Light and in a Dark Cabinet When Possible 

Exfoliating Acid - products have a shelf life of 9-12 months. The only things we don't suggest refrigerating are the Mandelic Acid Serums or Salicylic Acid Serums, as they can crystallize in the refrigerator. If this happens, you can set the product into a hot water bath to see if the crystals will dissolve.

Additional Items That Require Refrigeration and/or Kept in the Dark

Hydrosols and Distillates - remove 1 ounce of hydrosol and add it to a separate, sterilized spray bottle and spritzer. Keep the larger bottle in the refrigerator.
Carrier and Exotic Oils - generally refrigerate all carrier oils, although some very rich oils will solidify. This is fine. All you have to do is take the oil out, warm it up at room temperature, and it should liquefy. If not, set the bottle in a hot water bath and occasionally shake the bottle, which will hopefully turn into a liquid. Some oils, like coconut cream and jojoba oil, have a super long shelf life.    

Refrigeration of The Following Ingredients is Not Necessary, But it Won't hurt

Essential Oils - essential oils are best stored in a cool, dark place.   
Co2 Extracts - these should continually be refrigerated.
Butters - we suggest refrigerating our "skincare" butters. You can remove
what you need and keep the rest in the fridge.
Clays - keep in a dry, dark place. Shelf life is at least 2 years.
Herbs All herbs <i>(whole or ground)</i> should be kept in a dark, cool, and dry location.
Herbal (liquid) Extracts are created using grain alcohol. The alcohol pulls the constituents (properties) from each herb, root, trunk, leaf, and flower. They have a shelf life of 3-5 years.
They can be stored in the refrigerator or a dark, dry place.
Other Raw Ingredients - such as Sodium PCA, Honeyquat, Oat Beta Glucan, etc., will all have different shelf lives.
