@Doreen - That is the link. I’ve tagged it so it is one of the first discussions and never leaves the front page.
@Shubh123 - You can find sources for free formulas here.

A great opportunity for a knockout experiment.
-
Sounds like a pretty good guess.
-
@Mamo808 - It is impossible to disprove anything. What you should be looking for is evidence that a claim is true. You should also be open to having your mind changed by evidence. What evidence would change your mind about toners?
On toners, they’re probably an extra step that has little benefit but if people enjoy the experience of using them, they should.
-
@curiouslisa - you raise some interesting questions.
“Is there any mathematical way to calculate the right amount of antioxidants…”
Probably. But it’s not worth the time and effort to do it since the system is so varied. Better is to use trial and error, erring on the side of using too much. Antioxidant supplier will give you a suggestion.
“Will rosemary powder have the same antioxidant effect as rosemary C02 extract? Both have the same INCI, but I’m not sure if they’ll serve the same purpose.“
Not sure, but probably. Ask the supplier.
I wouldn’t recommend selling products that don’t have preservatives. Even if you can pass a microbial challenge test you have no defense if someone later sues you because of being injured due to microbial contamination.
-
Good article!
-
Your formula only adds up to 23.5%. What’s in the other 76.5%?
-
Gluten free is pretty easy to achieve too.
-
With that INCI name, I guess it’s an orange extract.
-
Maybe. They don’t follow proper labeling rules so it’s hard to say what they’re doing.
-
Does there exist a product like that already on the market?
-
My guess is they use meditation and don’t even think about their lips.
-
@Bill_Toge - good point!
-
It’s hard to say but having a listing of the whole formula would help.
pH drift perhaps. Water evaporation?
-
What are you using the natural herbs for? What benefit are they providing?
If there is a quantifiable benefit, you could conduct a test to see if they meet your requirements. If there isn’t a quantifiable test…well that’s probably a problem.
-
It’s difficult to say without seeing your whole formula but the most effective preservatives would be methyl / ethyl paraben and maybe DMDM Hydantoin. All of these are vegan.
-
I don’t know how the rules work in Australia but yeah you should report it to someone.
-
Glycerin is added to the water phase
-
@Zink - as you can imagine this is a complicated question. If it were easier, you would have gotten more serious answers.
My starting point would be vaseline. Then maybe a coating of hair spray. If that worked, you may be able to combine them into one formula.
-
@crazybean - You have to decide what kind of formulator you are going to be.
Are your formulation decisions based on science or are they based on your gut feelings?
The only evidence I could find related to the effectiveness of bee venom was a study that looked at 0.006% treatment. There is no scientific evidence to support putting in a higher level.
From a safety standpoint there is no good reason to use more of an ingredient than has been proven effective. There are good reasons to avoid using too much because there are frequent adverse reactions by consumers. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4440710/
@belassi - lol!
-
You’ll need to provide more information than that. Specifically, what ingredients are in your formula?
-
What would be your definition of “lasts 24 hours”?
I’m sure you could take any old petrolatum based lip balm and find traces of it still on the lips after 24 hours.
-
I honestly don’t know what you are looking for.
0.006% was tested in the study I referenced. So, if you want the results that they got in that study, use that amount.
-
@jeremien - what are formulators using instead?
-
According to this study, you would use 0.006%. Of course, the study is not a high quality one because they didn’t test against a standard moisturizer. Any moisturizer would give better results than the results from this study.
If personal experience is your guide then you use a high enough amount that convinces you it’s working. Only you can determine that.
Based on the research I’ve seen, I remain skeptical that it is a worthwhile ingredient to use for an antiwrinkle effect.
