Any problem with azulen?
Azulen was was trending in the 80’s and 90’s. Suddenly, it almost disappeared. Does anyone know if there is a relevant reason for this? I’ve read it can stain the machinery, but I’m not sure.
I’m not a formulator, but I’m thinking about to ask the formulator to put azulen in my products that he’s formulating - due the fact I want colorant free products with a nice blue color (LOL). -

@pma, I don’t see any problems with Azulene, but price. The pure substance in crystal form costs around Euro 700 per kilo. However I know many European manufacturers still widely use this ingredient in their lines, mostly for professional and salon Cosmetics( they can afford to use some expensive ingredients). Another source of the natural Azulene ( Chamazulene and Guaiazulene) is Chamomílla Matricária and some other plants. But the % of the active in them rarely exceeds 15%….

TKS Vitalys. I didn’t knew azulene is so expensive… Anyway, I think about 0.05% is enough to give a blue color…

@pma, I guess it depends on the Azulen form. I find Guaizulene in crystal form the best choice

@pma, Do you plan to put it only like a pigment or use it’s other ( main) capabilities for your product?
