Solubility and Mixing of Xanthan Gum in Lotion Formulation
Question
I am trying to make a DIY lotion using Xanthan Gum. I am confused about the difference between dissolving and dispersing and how to disperse Xanthan Gum in oil before adding water. Could you please explain the proper method for mixing and hydrating Xanthan Gum in a lotion formula, including why pre-dispersing in oil or glycerin is recommended?
Answer
Xanthan Gum Solubility in Oil
Xanthan Gum is a thickening agent that dissolves in water, not oil. Your observation that it precipitated and did not form a gel when mixed only with oil is correct because it is not soluble in oil.
The product information confirms that Xanthan Gum dissolves in water. The method of mixing it with oil or glycerin first, as mentioned in the product description, is a technique to help the Xanthan Gum powder disperse more easily. This dispersion prevents the powder from clumping when it is subsequently added to water, making it easier to achieve a smooth, lump-free gel texture when it dissolves in the water phase of your formulation.
To properly dissolve Xanthan Gum and form a gel, you need to mix it with water. High-speed stirring or vigorous shaking is typically required to ensure complete dissolution and hydration. While heat is not strictly necessary, warming the water slightly can sometimes assist in the dissolution process.
In summary, Xanthan Gum requires water to dissolve and form a gel. Mixing it with oil beforehand is a helpful step for dispersion, but it does not dissolve in the oil itself.
We offer several types of Xanthan Gum, including:
- Xanthan Gum (clear gel type, smooth texture)
- Xanthan Gum (clear gel type, normal texture, 200 Mesh)
- Xanthan Gum (clear gel type, normal texture, easy to spread)
- Xanthan Gum (clear gel type, normal texture, 80 Mesh)
