Body Wash for Sensitive Skin

My grandmother recently underwent chemotherapy and always complained to me that her skin became very sensitive, and there are no good body wash products advertised to those who are undergoing chemotherapy. For this reason, I am working with a few other people, oncologists, and dermatologists to build a body wash that is chemical-free (no SLS, DEA, etc) and fragrant-free (nausea-inducing). I was wondering if other people who are undergoing or have undergone chemotherapy feel the same way as my grandmother, and think the body wash I am thinking of would be beneficial.

Any feedback would be beneficial, and thank you for all the support!
