PRODUCT BULLETIN
SODIUM HYPOCHLORITE 12.5%
APPLICATION
Sodium Hypochlorite 12.5% is a strong sanitiser and bleaching agent suitable for use in all food, dairying, soft drink, fruit juice and brewing plants.
PHYSICAL & CHEMICAL PROPERTIES
Sodium Hypochlorite 12.5% is a water based solution and is a strong oxidising agent. It decomposes in the presence of heat and light and contains a small quantity of caustic soda. It will release chlorine gas when mixed with acids.
DIRECTIONS
For general sanitising use 1 volume to 420 volumes or 2.4mls per litre of cold water to give nominal 300ppm available chlorine. Contact period should be a minimum of 2 minutes.
PUBLICATIONS
Australian Standard 1087-1991 “Sodium Hypochlorite Solution for use in Dairy Industry”. Extract: E2 (a) Solution containing 12.5%M/V should not be used if more than 4 months have elapsed since date of analysis.
(b) If more than 3 months have elapsed - increase solutions by a factor of 2.
(d) Since heat accentuates decomposition - use at ambient temperatures.
SAFETY PRECAUTIONS
Take care not to splash on skin or eyes. If splashed, bathe thoroughly with water and remove contaminated clothing. if swallowed send for a Doctor; meanwhile give copious droughts of milk or water, preferable containing one dessertspoonful of bi-carbonate of soda.
HANDLING
Refer to appropriate Material Safety Data Sheet (MSDS)

50 gm/L 49 gm/L
100 gm/L 77 gm/L
125 gm/L 96 gm/L
8 Keeping Quality
of the product under normal storage conditions shall be such that the available chlorine shall not be less than the relevant minimum shown below :
Nominal Concentration Available Concentration after 28 days
50 gm/L 49 gm/L
100 gm/L 80 gm/L
125 gm/L 100 gm/L
Appendix A
a) It is recommended that Sodium Hypochlorite solutions containing nominally 12.5% (gm/L) available chlorine are not used if more than 4 months have elapsed since date of analysis.
b) If more than 3 months have elapsed, it is advisable to increase the strength of the use of solution by a factor of 2, so as to maintain germicidal activity.
c) Essential all surfaces are clean as deactivation occurs in the presence of organic matter.
d) Since heat will accelerate decomposition, sanitising operations should be performed at ambient temperatures.
e) Sanitising should be done not more than 30 minutes prior to use of the plant.
f) As a guide 2 min contact at nominal available chlorine concentration of 300ppm is considered satisfactory.
