FTM, laundry detergent help please

Samantha • Semi-professional tiny human wrangler
So hubby brought home some ECOS laundry detergent because we had heard it was great for babies, it is free of dyes etc and is plant based... however the particular one he brought home says it has built in fabric softener? 
Should I not use this one? Thoughts? This laundry detergent shenanigans has me a bit confused. Thanks in advance.
