  1. Polymer Applications in Cosmetics Christopher Shoup Christopher Yanosko Erik Becker Kevin Chen Patrick Lathrop

  2. What are Cosmetics Cosmetics are substances used to enhance the appearance or odor of the human body.

  3. Common Consumer Products • Skin Treatments • Sunscreen • Nail Polish • Lipstick • Shampoos/Conditioners

  4. Common Consumer Products • Skin Treatments • Sunscreen • Nail Polish • Lipstick • Shampoos/Conditioners

  5. Silicones for Skin Treatments • Wrinkle Treatments • Polydimethylsiloxane • Skin Coloring • Cyclopolydimethylsiloxane (Cyclomethicone)

  6. History • Polydimethlysiloxane has been used in lotions since the 1950s. • Cyclomethicone was put into use in the 1980s.

  7. Role of the Polymers • Most skin care products are emulsions • Silicones are used as the emulsifiers

  8. Wrinkle Treatment • Polydimethylsiloxane • Delivers materials that reflect and scatter light • Absorbs Sebum • Dries into a film

  9. Skin Coloring • Cyclomethicone • Apply pigments like Titanium Dioxide • Evaporate and leave the pigment on the skin

  10. Common Consumer Products • Skin Treatments • Sunscreen • Nail Polish • Lipstick • Shampoos/Conditioners

  11. Background of Sunscreen • Sunscreen dates to 400BC • First documentation • Christopher Columbus’s visit to Hispaniola • First commercial sunscreen produced in 1928 • Water soluble • Caused skin irritation

  12. Polymer usage • Better deposition onto skin • Encapsulating sunscreen agent in polymer nanoparticles • Solvent displacement method • Slating out method • Increase water resistance

  13. Polymer usage (cont.) • Film forming polymers • Inorganic UV filters integration • Water resistant • Waterborne Polyurethane • Reduce absorbance into skin • Reduce migration of product across skin

  14. Common Consumer Products • Skin Treatments • Sunscreen • Nail Polish • Lipstick • Shampoos/Conditioners

  15. Nail Polish • History • 17th century • 19th century • 1920’s

  16. Polymers Used • Tosylamide/formaldehyde resin • Nitrocellulose

  17. Properties • Nail Polish Film • Plasticizers • Solvents • Pigments • Ultraviolet Stabilizers • Sparkling Particles

  18. Problems • Organic Solvents (Acetone) • Irritate skin around the nail • Produce onycholysis • Cause dryness or brittleness of the nail • Allergic Reactions • Contact Dermatitis or Eczema

  19. Common Consumer Products • Skin Treatments • Sunscreen • Nail Polish • Lipstick • Shampoos/Conditioners

  20. Polymer Applications for Lipstick • After seeing how polymers relate to uses in nail polish, we can examine how they apply to lipstick • Polymers are used in lipstick to make it more long-lasting, more comfortable, and optimize color • Lipstick is the least expensive and most popular cosmetic in the world today • “In 1986 lipstick sales in the United States were more than $720,000,000” 1 http://en.wikipedia.org/wiki/File:MAC_pink_lipstick_%281%29.jpg 1 Lucking, Peter S. "How Products Are Made." How Lipstick Is Made. Web. 07 Apr. 2012. <http://www.madehow.com/Volume-1/Lipstick.html>.

  21. Brief History of Lipstick • Egyptians used plants containing mercury to produce henna • Trace amounts of lead, cow brain tissue, and crushed beetle shells • Waxes, oils, pigments, and emollients are used http://moonhex.files.wordpress.com/2011/04/egyptianwomenapplyingmakeuptpic.jpg

  22. Polymers used in Lipstick • Polybutene • Binder, epilating agent, viscosity increasing agent • Formed by polymerizing isobutenes and butenes • Polyurethanes • Long-lasting, fast drying • Non-greasy, easy to remove Figures taken from Wikipedia

  23. Processing of Lipstick • Polybutene - $0.43 per pound • Lipstick - $4 to more than $60,000 Figures from: Lucking, Peter S. "How Products Are Made." How Lipstick Is Made. Web. 07 Apr. 2012. <http://www.madehow.com/Volume-1/Lipstick.html>.

  24. Common Consumer Products • Skin Treatments • Sunscreen • Nail Polish • Lipstick • Shampoos/Conditioners

  25. History of Shampoo Dates back to the mid 1700s First introduced as therapeutic head massage with natural oils and fragrances Commercialization began in early 1900s

  26. Shampoo Ingredients/Formulations • Detergents such as sodium lauryl sulfate • Thickeners • Fragrances/Preservatives

  27. Polymer Usage in Shampoos Advantage Increase comfort in shampoos Disadvantage Ineffective cleaning

  28. Polyquaternum • Cationic polymeric conditioner • Helps with wet combability and reduce electrostatic charging of hair • Polyquaternum 44

  29. Future Directions of Cosmetics • Lower cost • Increased efficiency with technology improvements
