When you're almost done with liquid soap and can't pump any more out will adding H20 make soap less effective?

Question

sometimes people want to use up as much soap as they can so they add water to the bottle. Will that dilute the soap so much that it won't be as effective?

Answer 1

Well yes but don;t you mix it with water anyway when you use it?

Answer 2

yes,it may dilute the solution and may lessen the effect too...but it even depends upon the ratio of soap solution and water
