HOW DOES WATERPROOF MASCARA WORK?

RELATES TO MY LIFE BECAUSE...

• I've worn waterproof mascara before
• I know it does not come off easy
• Went to a water park and mascara didn't come off
• Picked this question because I wanted to know more about it

WHAT DO I ALREADY KNOW?

• It's a struggle to take off
• Definitely stays on when wet
• Need to scrub to get off

NOTES

• Contains petroleum distillate and waxes and oils
• Hydrophobic molecules
• Can be dissolved in oil substance(oil based makeup remover)
• Has silicone and dimethicone copolyol in mascara and both are fat based
• Water won't mix with product. Oil and water don't mix, leaving mascara good

NOTES CONTINUED

• Waterproof mascara is called hydrophobic
• This kind of mascara has stronger hydrogen bonds
• Non polar

CHEM VOCAB

• Petroleum Distillate:
• Products made from crude oil
• That have been distilled in a refinery
• Then processed further and purified

CHEM VOCAB

• Hydrophobic molecules:
• A property of a substance to repel water
• Tend to be non polar molecules and group together
• Examples are oils and fats

CHEM VOCAB

• Fat based:
• Waterproof mascara is fat based
• Helps mascara not to run when crying or when eyes get wet
• Does not mix with water

HOW HAS THINKING CHANGED?

• Before I never knew how waterproof mascara worked
• Now I know it's the wax that keeps the mascara intact and to not come off

RESULT OF THIS

• Need to buy the right makeup remover
• to get mascara completely off.
