Homemade laundry detergent

So I read a little article about how the top laundry detergents are putting chemicals that cause cancer and damage to the nervous system in them. The article also said that they are NOT listing these chemicals on the box with the other ingredients. I took the $30.00 box of TIDE that I had just purchased from Costco straight back to the store and started researching how to make my own detergent at home. As it turns out it is easy and so inexpensive. I was pretty surprised. I am a couple loads into my first batch. It is working very nicely and the clothes feel like they also have been treated with fabric softener. I love the smell of it (you can't smell the vinegar no matter how hard you try)
I plan to experiment with several and stick with the one I like the best.
Here is the recipe for the 1st one. It is one of the only recipes I was able to find for powder.

1 cup Vinegar (white)
1 cup Baking Soda
1 cup Washing Soda
1/4 cup liquid castile soap

• Mix well and store in sealed container.
• I find it easiest to pour the liquid soap into the bowl first, stirred in the washing soda, then baking soda, then added the vinegar in small batches at a time (the recipe foams up at first). The mixture is a thick paste at first that will break down into a heavy powdered detergent, just keep stirring. There may be some hard lumps, try to break them down when stirring (it really helps to make sure the baking soda isn’t clumpy when first adding). Use 1/2 cup per load
