DIY baby detergent

I am wondering if anyone has experience making their own baby laundry detergent? I found some recipes online for Dr bronners Castile soap and baking soda plus some essential oils of choice. And for softener vinegar. Any opinions or advice? I don't wanna use commercial soaps as they have lots of chemicals and my skin is very sensitive I can't even use them myself. Would this mix of ingredients be fine for baby?
