A-Z Ingredients

This dictionary is a work in progress. Every Saturday, I publish a new post in my Know Your Ingredients series, and then add the link to this page. I thought it’d be handy to have them all gathered together, so if you’re wondering what an ingredient in your favourite moisturizer or mascara does, you can easily and quickly look it up. If the ingredient you’re looking for is not listed here yet, feel free to contact me and request it.

    • Marie, Zea Mays seed flour is a substance derived from corn that is used to dilute or increase the volume of a product and, in pressed products, to hold the ingredients together. In addition, it also has absorbent properties. Hope this helps. :)

        • Marie, as far as I know this ingredient would be used in an exfoliate product to give it a certain consistency/texture but it doesn’t have any exfoliant properties. While it is a safe and good ingredient, if you’re looking for an exfoliating agent, I’d recommend AHAs (like glycol acid or lactic acid) and BHA (Salicylic Acid), which are gentle and effective.

  2. Missing a couple that I thought important:

    Ferric Ammonium Ferrocyannide, Iron oxides, Chrome Oxide (color) & Chrome Hydroxide (color, as in Greens).

    • JL, thanks for your comment. You’re right, some important ingredients are missing. That’s because th dictionary is still a work in progress. Every Saturday I post about a new one in my Know Your Ingredients series and then add the link here. I will write about the ones you mentioned soon.

    • Boa, this dictionary is still a work in progress. Every Saturday I add a different ingredient to it. So far, I’ve added Methylparaben, the other parabens will follow shortly. :)

  3. Very nice blog! But if you check out Paula Begouns web site you can read that silicone doesn’t actucally cloge pores and therefore a perfect ingredient for acne prone skin.

    Well done tho! =)

    • Micke, thanks for your comment. I’ve just checked her website and you’re right. I never really believed that silicones suffocate skin but I thought that the less volatile types such as dimethicone could cause problems for people with sensitive or acne-prone skin who are easily irritated. I’m glad that’s not the case.

    • Eli, Perlite is formed from the expansion of volcanic rock, and is used in cosmetics as an absorbent. Maltitol is an humectant and a skin conditioning agent. It helps increase the water content in the skin, and hold the moisture in, thus helping to keep skin soft and smooth. Hope this helps. :)

      • Thanks, they don’t sound as something dangerous, so it’s OK – they are ingredients in Garnier’s new BB cream for oily skin :)

    • Michela, that’s a humectant: it attracts water from the environment into the skin, helping it to stay hydrated.

  4. I’m trying to find out if Kiko Make Up Milano products have salicylates in them. I cannot find ingredient lists on any of their eye make up products.

    • Cindra, I think some Kiko products use salicylates, but I’m not sure if they are included in the eye ones. I think your best option would be to contact Kiko directly and ask them. Sorry I couldn’t be of more help.
