Why vaseline became yellow starting with white colour?
I want from expert giving thoughts why the vasline became yellow starting from white one? <div>
just a constatation, why all the vasline which changed the colour is in the same line?
And is there any solution to prevent this coloration changing?

Oxidation is the answer. Hydrocarbons in Vaseline chemically change by reacting with air, UV light, introduced contaminants. Heating can also speed up oxidation. To slow it down, keeping it stored in a cool dark place might help.

Thanks a lot Perry, I thought that vasline is soo stable versus oxidation.
So in bad condition of storage can just two months make vasline have oxidation ?
Then can vitamine or can you propose uv filter to solve the problem?

I agree with @Perry44 about the oxidation. Now, what could happen is that your vaseline wasn’t as refined as some others, and those traces could contain materials prone to oxidation.
