I'm making a low pH facial cleanser formula and currently using powdered green tea as a colorant, but it's quite expensive. Any other good potentially beneficial green colorants that would go well in such a formula? I have green chromium oxide, but don't think it's beneficial.

The most famous case in the field showed that you would have to leave the cleanser on for 2 minutes to have active effect.

There is no particular info on the case of green tea:

In my opinion they would probably give you the same effect.
The study shows that want seems to be a topical emulsion does when used post wash.
I like my cosmetics to have supporting background, I just wish it wasn't just a gamble of should or could.
Would you be willing to sponsor a study showing that your cleanser with green tea has any advantage over non green tea formulated cleansers?
Also, for the purpose of critical thinking, the study is very poorly designed, they are studying panthenol versus nothing, when it should be panthenol versus other known humectant. They have no positivecontrol which makes the study a bit moot. Not to mention that the test subjects did not apply placebo vs concentration test, they applied concentration test vs other concentration test, which means there was no control for any of the subjects.
So I don't quite understand, do you want to add these products to your cleanser because they are a formulation improvement or because they might be?
It makes a huge difference for those on the consumer side.
Panthenol needs to be shuttled through the cell membrane, needs to be converted from the alcohol for to the acid and finally needs to be shuttled to the mitochondria where it can act as a cofactor for co-enzymes. In the study they actually use a foam roller during the washes (I suppose to exfoliate the are to improve absorption post application). Some things just need a bit of time/right ph/right concentration. For the case of polyphenols I don't think there is data for that.
Jojoba beads would be a great add-on to the formula or even some forms of clay.

-Jojoba has one of the lowest comedogenic indexes and it is together with mineral oil, kukui and neem one of the best tolerated by acneic skins
- Regarding abrasives, I don't know if you are using that as a tecnical term or the same way I understand it, anything that will help with keratinocite function will help, so, jojoba is both low comedogenic index and acceptable exfoliante given their bead sizes, and so are many of the kaolin and bentonite clays due to their sulphur content.
Also I would consider abrasives, mandelic acid, glycolic acid, konjac sponges, Lactic Acid and the basic clarisonic and they are the some of the best resources for acneic skin.

These are mechanical exfoliants that are pretty ubiquitous :

As I noted, using it as a colorant with potential benefits, using powdered green tea AND green tea extract. Whether the consumer thinks that's a good idea is up to them. I will include instructions to leave the cleanser on the face for longer to increase the chances of a positive effect.
Now keep in mind this thread is about colourants
Wow, that makes me really sad
Think you for being so frank. I am going to double my attention on what I buy
So basically the FDA doesn't want to see any ingredients that are purely used as colorants except for the ones they've approved?
Can someone post sources?
