>>> Why is 0.50% called "Full Strength"? The term "Full Strength" refers to the highest concentration tolerable to the skin, which is Sodium Hypochlorite 0.50%. "Full strength" has been the standard industry term since it's inception.
>>> Any strength must be buffered before it can be used on the skin. Never apply diluted bleach directly to the skin without buffering it first.
>>> Century's Sodium hypochlorite products are buffered (lowering the pH to about 10), which is much more tolerable to the skin when compared to diluted bleach.
