I said above "Odour-b-gone and napisan have the same active ingredient." but that was from a remark on the caravan
forum so I thought I would
check.
The correct answer is:
From the MSDS, Odour-B-Gone's main ingredient is Sodium peroxy carbonate - Na2CO4 - at between 10-30% by weight.
Nappisan and the various
home brand derivatives use Sodium Percarbonate - Na2CO3·1.5H2O - at varying concentrations up to 35% in some
home brand products.
Both work by breaking down to Hydrogen Peroxide and inert salts on contact with water. Hydrogen Peroxide - H2O2 - is a strong disinfectant that decomposes to oxygen and water.
Wikipedia notes about Hydrgen Peroxide that:
"It is a weak acid, has strong oxidizing properties, and is a powerful bleaching agent. It is used as a disinfectant, antiseptic, oxidizer, and in rocketry as a propellant."
Not too sure about the last one - perhaps you shouldnt smoke while on the thunder box or you might achieve orbit! :o)
