A simple thickener that gives water-based cleaning and personal care recipes body, helping them cling to surfaces rather than running straight off. When paired with Glycerine, it disperses smoothly without the frustrating lumps. Use it to thicken everything from dish liquid and hand wash to shower and toilet gels.

What is it & does


Xanthan Gum is a fine powder produced through fermentation and used as a thickener and stabiliser in everything from personal-care products to household formulations.

It doesn't clean, degrease or descale.

Its job is to change the way a liquid behaves.

When Xanthan Gum hydrates in water, it increases the liquid's viscosity. A runny spray can become a gel that clings to a wall. Diluted Castile Soap can become a thicker hand wash or dish liquid that is easier to dispense.

That matters in cleaning because sometimes your active ingredient is already exactly right; you simply need to keep it on the surface long enough to do its job.

Important Info

Start small
Xanthan Gum is extremely effective in tiny quantities. Add too much and your smooth gel can quickly become far thicker than you intended.

Never throw it straight into water
Xanthan hydrates so rapidly that dry powder added directly to water can form gel-coated lumps with dry powder trapped inside.

Mix it thoroughly with Glycerine first.

Give it time
Xanthan continues to hydrate and the finished product may thicken further as it settles. Get close to the consistency you want, then allow it some time before deciding it needs more.

Storage
Moisture is the enemy. Keep the powder tightly sealed and completely dry so it does not begin hydrating or clumping in storage.

Understand why this works

Learn why Xanthan Gum clumps the moment it meets water, how Glycerine keeps those particles separated and why combining the two first gives you smooth gels with surprisingly little effort.
