Hi is me again I just tested liquid soap, in red and blue litmus papers. the blue did not turned red which means is not acidic, but the pink looked kind of turning blue and although I try it different times it still looks like wanting to turn blue, I don't know it its because the soap is green and that might have affected the results. I would like to know if liquid soap is in fact a base just to verify my answer.
Thanks again :)

Your soap is probably neutral-they try to get it as close to neutral as possible to be gentle

Most soaps are slightly basic. The "harsh" soaps are those that haven't washed as much of the alkali out of the product. The "better" soaps have washed most of the alkali out and usually a perfume of some kind is added.

'Neutral' soaps are slightly acidic, pH 5.5 or so.

Standard soap, sodium palmitate for example, is basic as it is the salt of a weak acid and strong base.
