Keeping Homemade Liquid Laundry Soap from Separating?

Try adding a squirt of dishwashing liquid. I read somewhere that it helps with splitting.
I used to have the issue of my homemade liquid splitting and I use the borax washing soda and soap recipe.

I tried extra blending with a hand blender and also used a jug blender but it still split after a few hours.
I did a trial... about a cup of the liquid and about a teaspoon of dish soap mixed in a small jar checking for 2 days and it worked perfectly...no splitting.
I now add a squirt to each 2lt bottle I use to store and have not had any splitting what so ever.
I have not added it to the main pot... only added after, when separating into smaller bottles. I still shake prior to use as it does tend to get a bit thick at the top but it evens out.
