PPD content in henna and Bronsun

Deborah Hendren

PPD -
Ok, I swear I don’t just sit and look at this all the time, although I am STILL in lockdown in Glasgow till 11th, so maybe I’m just super bored 😂😂
Firstly, I’ve attached the MSDS for bronsun, you’ll see PPD levels are 2%, EU regulations have them set at 2% maximum, which is why this is the max %,
Henna has in different forms. PPD - and interestingly enough the MSDS for dyotics shows 5-10% PPD. Which is curious as that’s supposedly too high. But Henna is subject to a different set of rules when it comes to the % of p-phenylenediamine,
The PH level of the hair and the processing time in henna. Means it can have a higher % of PPD, in some cases up to 10% - but that’s subjective,
Elleebaana henna appears to be PPD free, but does contain p-aminophols :
All permanent hair dyes contain a ‘primary intermediate’; these are often p-diamines or p-aminophenols. They are oxidised by hydrogen peroxide to give reactions which then go on to react with couplers to produce dyes.
Finding a ppd free product generally doesn’t last, but anything with a skin stain will have some sort of PPD (or intermediate)
The real dangers are black henna, which have up to 30% ppd which is why that’s banned. It’s a real issue for people to have allergic reactions, but bronsun is no higher than hennna, just don’t forget to patch test
Another interesting article below and it’s actually a good reference point for learning
