[quote="llerickll"]The story of
Niacinamide Hydrolysis reaction becomes
Niacin Under acidic pH, refer to this study
https://jpharmsci.org/article/S0022-3549(15 )33604-2 /pdf He said 10% solution
Niacinamide at heating 120c x 20 min Not found
Niacin Happens, another setting at pH 2 + 90c takes 75 hours to find
Niacinamide change to
Niacin At 50%, every 10c increase in temperature doubles the reaction rate. If calculated backwards, at pH 2 + our home temperature of 30c, it's expected to take 4800 hours, or about 6 and a half months. We should have been bitten by acid pH 2 in another study
https://pubs.acs.org/doi/abs/10.1021/ac60053a025 The solution was stored at 45c x 6 weeks in acidic conditions (pH not stated). Found
Niacin not more than 2% if it is room temperature at 25c x 6 weeks found
Niacin less than 1% In addition to pH, viscosity affects the reaction rate, for example: together, the more viscous the serum, the change from
Niacinamide to
Niacin also the slower, so the skin care
Niacinamide change to
Niacin and flushing the face red. It should be found quite a bit
Wow, this information is very clear. Similar to Aunt Paula's description on her brand's website, she said that she used it and applied it over and it had more benefits than negative effects. and belief in prohibition
It's very ancient. what about this Thank you very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very very much
