So I have taken this as the topic for my investigatory project in chemistry, however I am not able to find any convenient way to do it.
How can we prove that a lipstick contains lead in it or a foundation and concealers have color in them, in a simple way.
And can we do it with the process of qualitative analysis, like showing a precipitate of lead in lipsticks??
I need answers ASAP.
Thanks...

Does your lab at school, have the equipment to test for this ?

No simple way. Lab tests using Qualitative and Quantitative analysis.
