Know your ingredients: Mineral Oil (Liquid Petrolatum)

mineral oil cosmetics

What it is
Mineral Oil (also called liquid petrolatum) is a clear and odourless oil derived from petrolatum. It then undergoes a strict purifying process that gets rid of all the toxic stuff and makes it safe for use.

What it does
Mineral oil is one of the best moisturizing ingredients available. It creates a protective barrier on the skin that prevents moisture loss.
It is also a solvent used to remove makeup and temporary tattoos.

Side effects
Mineral oil doesn’t clog pores. However it is an occlusive agent, and if you use it with products that have comedogenic ingredients, they will get trapped under the skin, causing pores to clog. However, it can make acne worse.

    Baby oil has a high concentration of mineral oil, doesn’t it? I try to avoid mineral oil and petrolatum as much as I can although they are good moisturizers. Guess what, La Mer is choke full of them! I wrote about it a while ago.

    Lydia: I’m glad you enjoyed the post :)

    Dao: yes, baby oil has a very high concentration of mineral oil. I don’t mind using it as a moisturizer, although I try to use products that don’t contain when I can. I’ve just read your post about La Mer, it is very interesting. I’ve been wondering whether to but La Mer products or not. Everyone keeps saying how good they are, but they are also so expensive! I’ll keep the info in mind, thanks.

    I got baby oil in my eye. How do you get rid of the blurred vision? It’s been about 24 hours now and not any better.

  4. says

    Monique, I’m sorry to hear that. When you get baby oil in your eyes you should flash it out with water straight away and the blurred vision should go away shortly after. But if you stil have problems after 24 hours, you should consult a doctor immediately.
