What does Xanthan Gum do?

It has a few functions but the main one is to thicken liquid solutions naturally. You will find it as a thickening agent in shampoos, conditioners, detergents & a lot of cosmetics. 

Can I add the xanthan gum without glycerine?

Yes, but you will need to be extremely patient as it will be very lumpy & can take some time to whisk. If you do it this way, you may want to use a stick blender. Bearing in mind if you use a stick blender the mixture will foam up & almost double in size, so make sure your bowl is big enough. You may need to let it 'rest' overnight to reduce back down. 

Why do you mix glycerine with xanthan gum? 

It acts like a ‘roux’ (a mix corn flour & butter) used to thicken a soup, the butter helps spread the flour more evenly through the soup so there are less lumps. The glycerine works the same way with the xanthan gum as it does not react with it like water does. It's amazing really. 

Is this safe for septic tanks?

The ingredients are mild, safe & biodegradable which should not affect the bacteria in septic tanks like harsh chemicals can. 

Can I thicken Vinegar instead?

You sure can, just follow the steps to add Xanthan Gum & it will create a similar product

This is a truly effective cleaner. I won’t be going back to commercial cleaners after trying this. It only costs cents to make and does a fabulous job cleaning the toilet. Also does a great job on soap scum in the shower and bath tub.
