We got the following preparation: Hydrogen peroxide 6% (20V %0) 50g Ammonium hydroxide to pH 9.5 Water up to 100ml hairs over lip decolouring

To begin with, my knowledge is the concentrated solution hydrogen peroxide or Perhydrol 30% or 100 volumes. Just oxygen water is 3%. I thought that for white colors of her 10% was used. But for the lip, we may have to be more cautious. So I think 6% perhydrol 50g will be sufficient.
