Is this unscented enough that I could use it as a carrier for essential oils to make my own liquid soap?

Yes you can! I have purchased it for this reason. I have added essential oils to it, and I have also added fragrance oils to it with great success!

Can this be used to wash laundry; either by hand or with a washboard?

Absolutely! 1 cup Castile soap, 1cup baking soda, 1/3 cup salt, 2 cups distilled water (warmed), essential oils (if you want a scent). Only laundry soap we use now. I use vinegar in the softener dispenser. Just don’t mix vinegar & the baking soda. One is an acid the other a base and cancel each other out.

what are the ingredients in Dr. Bonner's Castile Soaps?

I don't know contents, but know the "unscented" is very mild & I can use from head to toe, shampoo & body wash & doesn't agrivate my psoriasis.

I purchased a 32 oz. bottle of unscented baby-mild pure-castile soap. I was hoping for it to be truely unscented but it smells like peppermint. ??

It should not smell like peppermint. I purchased a two bottle set of the unscented product. One of the bottles was unscented and the other smelled of lavender. Some people may not have noticed the difference but I have a diagnoses of fragrance hypersensitivity along with asthma and allergies and as soon as I opened the second bottle I sensed the lavender fragrance. The thing is I've purchased this product many times with no issue. I wanted to believe this was a one off matter but reading your question makes me wonder if this is more widespread.
