My go to soap is ALL TERRAIN's Wonder Wash ... I have two backup bottles.
- fragrance free (of course)
- pH neutral (which makes it a multi-purpose soap)
- biodegradable (it is advertised as a Hiker's soap) ... it probably isn't environmentally friendly/neutral, but biodegradable is a good start
- filled with eight ingredients ONLY
I've used this to: clean my makeup brushes, degrease my body, wash my hair, and wash my face (no eye stings). I have not yet used it to bath dogs, but I'm sure it will happen eventually.
This product receives a low 1/10 on the hazard scale at Cosmetics Database. I thoroughly recommend it to those with sensitive skin.
