Hi,

I am not bragging I am highly knowledgeable of the topic. If I was I would not pose the question.

 I certainly did not miss the point of your discourse. I am aware that that the ingredients of the intended use have already been pre approved as but there is multiple other ways the final formulation can go wrong or become non-purposefully contaminated and that is why safety testing is needed if one aims for large or even small scale manufacturing to test a number of qualities of the product.

 And as a point of interest as a person that I assume knows much more than me on topics such as this, I imagine you also know there is a lot of animal testing still taking place with species under no protection of federal law (most of them) or just kept away from public eye. It is extensive despite being inhumane and not an area of research I am particularly fond of.

 Lead and urea were only assumptions of ingredients that may appear restricted in some countries in the formulation of products such as lipsticks.

Thank you for your reply johnb! You are right, maybe testing does not differ so much from other cosmetic products. My only worry was the fact it is applied on the mouth and this would require more tailored testing approach.

Based on what I could dig out as information there will be the standard testing methods: animal, human testing and in vitro sampling. Also something more specific to look out for in lipstick samples will be lead or urea. I have come across some other oral examination of makeup but if I am right this is not safety but efficacy testing instead.
