Who accused his mate and was it connected to bathtime?
If this is "ishoo" based (and such an over reaction does come under the umbrella of ishoo) then it needs to be worked through.
Unless you want your child to potentially grow up under the merky cloud of a father going on to withdraw to an even greater extent as she grows, based on fear of being seen as a person who sexually attracted to his own child.
I am the (formerly teenage) child who had a mother who made an utterly false accusation of paternal sexual interest.
So I know false accusations are not impossible.
But we as parents have to keep perspective and fight back agaisnt fears and feelings that don't make a whole lot of sense nonetheless, and sort out anything irrational or demonstrates skewed risk aversion that is not "small potatoes league" becuase our children need us to.
It's one thing for your kids to pick up a parental irrational fear of large hairy spiders.
It's another for them to grow up sensing something is "off" or withheld in their relationship with a parent, becuase the parent is afraid of being seen as too close or sexually predatory.
And your husband needs to sort it out for his own sake too. He needs to work out if he is over compsating becuase he has doubts about his friend's innocence and feels dislyoal for having those feelings, there is something lurking in his past triggering it, or he has started to view "society" as a bit too dangerous and unpredicatable on a personal level.
Nobody can be feeling well chipper and at peace when they are lugging around a signifcant fear that an false accusation of a horrible, vile crime against their own child is a real possibility.
And it is not a healthy fog to hang over the family in any way shape or form.
