Vanish is Sodium percarbonate.
Yes it has that but i wanted them to confirm whether its the same product as sold in the UK or whether there are some changes. They refused to answer.
I think it is because the price is comparable. Around Rs.1k for
1.5kg in the UK or Rs.200 for
400gm in India. Price is generally a good indicator of parity.
Does this mean other products that use this 'oxy' term also contain percarbonate ? like Henko's stain champion with 'oxygen power'
For that need a way to test for the presence of percarbonate. Easy. 5g in a steel flask and then pour boiling water slowly half full. Then wait for the fizz.
This happens with Vanish. But there is no fizz with Henko's
stain champion with 'oxygen power'
So the term Oxy is used in a marketing sense only with other products.
I'm trying to come up with an affordable and effective way to do tub cleaning that can be performed regularly.
Pure Sodium percarbonate on its own needs 50 degrees and above to be effective.
Percarbonate releases hydrogen peroxide which then releases oxygen and this process does the cleaning.
Vanish can work at lower temperatures because it contains a bleach activator called TAED. It's out of patent so its there in the Vanish sold in India.
With a bleach activator the percarbonate is turned into peracetic acid which is even better at cleaning and this process begins at 25 degrees on. The cleaning increases further at higher temperatures.
It's that peracetic acid that oxidises aluminium vessels turning them black in a dish washer. Don't want aluminium vessels to turn black then use a dishwash detergent that does not contain percarbonate like
Fortune. Price is less because it does not contain percarbonate. Same applies with laundry detergents when compared with their western equivalents. Ariel sold in the west has percarbonate. What about the one sold in India ? do the boil test and see.
Dishwasher tablets also contain percarbonate and bleach activators but the safety data sheets i've seen indicate it contains only a third of the percarbonate of vanish.
So Vanish is a better candidate than dishwash tablets to clean washing machines but the problem with Vanish is it foams too much.
