What is BP Grade?( Hydrogen peroxide )

what does BP grade mean – BP Grade: Otherwise known as pharmaceutical grade chemicals, this category is very similar to the American USP Grade. BP Grade chemical products conform to the standards established by the British Pharmacopoeia, which are based on the level of purity and lack of contaminants in a substance. HOWEVER it is still not fit to be used internally! so for drinking drops or nebulising only Food Grade should be used – BP grade can be used externally on wounds to clean skin when it is diluted to the correct 3 percent or less
