MSDS you say... I did before I posted. The ingredients in Drano are:
HYPOCHLOROUS ACID, SODIUM SALT; (SODIUM HYPOCHLORITE)
SODIUM HYDROXIDE
Broken down:
HYPOCHLOROUS ACID= This is a derivetive of Chlorine (not chlorine)
SODIUM SALT= Is a dietary mineral essential for animal life, composed primarily of sodium chloride.
SODIUM HYPOCHLORITE= Is not Beech, Household bleaches usually contain about 5% sodium hypochlorite (about pH11, irritant), and more concentrated bleaches contain 10-15% sodium hypochlorite (about pH13, corrosive).
SODIUM HYDROXIDE = Is lye and caustic soda. (The killer)
Again the injection is less than 0.5ml per shot. Thanks to those who hung on the subject.
