Why Are Clean and Clear Oil Absorbing Sheets Made With Mineral Oil?
Posted Oct 07 2011 2:01am
Mandy must know…I remember using Clean & Clear oil absorbing sheets a few years ago, I wanted to try them out again. However I read the ingredients and I noticed it had mineral oil. What is the purpose of the mineral oil & do I need to be worried about using these on my oily skin? (via Facebook)

Great question, Mandy! Why in the world would an oil absorbing sheet contain oil? To get the answer we have to take a look at the ingredients.
Polypropylene
This is the plastic material used to create the sheets.
DMDBS
Also known as 3, 4 Dimethylbenzyl Idene Sorbitol, this is a modifier added to the melted polypropylene to form a complex nanofabril structure that gives the sheets their characteristic flexibility and helps “wick” oil away from the skin.
Mineral oil
Modifier for the plastic that reduces the cycle time for shaping and processing the sheets. It’s also conceivable (although this is just a theory on our part), that the mineral oil in the plastic matrix may help with oil absorption due to the chemical principle of “like dissolves like” (that’s for all you hard core chemistry geeks in the audience.)
Zinc stearate
Opacifier that makes the sheets look creamy not clear.
Ultramarines
Pigments which give the sheets their characteristic baby blue color.
Clean & Clear Oil absorbing sheets are a great way to degrease your face. The mineral oil used in their production won’t make your oily skin any worse.
