Homemade or aluminum free deodorant

Has anyone tried this? A dermatologist friend told me to be cautious with it since the baking soda can irritate some people, so I just wondered if anyone has tried this?? What was your experience?

I have super sensitive dry skin, so wearing normal deodorants every day all day really irritates my skin to the point of dry and itchy and bleeding sometimes. I found a recipe with coconut oil, corn starch or arrowroot powder, baking soda, and scent of your choice. I made it with less baking soda and added a tiny bit of local honey and some vanilla extract and it smells so good and is so moisturizing so far, so I’m feeling hopeful. I’m not a very sweaty person and I don’t really smell even not wearing any deodorant on a normal day so I’m hopeful 🤞
