  1. Acrylic (Methacrylate) Nails Module 28

  2. Editor’s note • All artificial nail enhancements products are based on ingredients from the acrylic family • Sub-branch called “methacrylate” • Two-part liquid and powder enhancement systems • “Acrylic” – general term for large group of ingredients

  3. Liquid and powder artificial nail enhancements products based on the methacrylate subcategory • Two-part liquid and powder enhancement system referred to as acrylic (methacrylate) nails

  4. Introduction • Acrylic (methacrylate) nail enhancements created by combining: • monomer liquid • polymer powder • Liquid and powder system

  5. Monomer • “Mono” means “one” • “Mer” stands for “units” • Monomer is one unit called a “molecule”

  6. Polymer • “Poly” means “many • “Mer” stands for “units” • Polymer means “many units” or “many molecules”

  7. “liquid and Powder Nail Enhancements” • Applied three basic ways • Natural nail as protective overlay • Over nail tip • Sculpted to extend natural nail using a flexible form • Natural hair brush best to apply products • Sable is best

  8. Brush immersed in monomer liquid • Natural hair bristles absorb and hold monomer like a reservoir • Tip of brush touched to surface of dry polymer powder

  9. Monomer absorbs polymer – small bead is formed • Bead is carefully placed on the nail surface and molded into shape with brush • Liquid is usually made from ethyl methacrylate monomer • Can contain other monomers used as customizing additives

  10. Polymer powder is also made ethyl methacrylate monomer • Polymer powder is made using a special chemical reaction called polymerization • Process • Trillions of monomers linked together to create long chains • Long chains create tiny beads of polymer used to create certain types of artificial nails

  11. Special additives blended into both liquid and powder • Ensure complete set or cure • Maximum durability • Color stability • Shelf life • Liquid is picked up by brush and mixed with the powder • Bead forms on the end of brush and quickly hardens • To happen special additives called catalysts

  12. Catalyst • Additive designed to speed up chemical reactions • Added to monomer liquid • Used to control the set or curing time • Monomer liquid and polymer powder combined the catalyst helps control the set-up or hardening time • Energizes and activates the initiators • Initiators start a chain reaction that leads to the creation of fantastically long polymer chains

  13. Polymerization process begins the second the liquid in the brush picks up powder from the container and forms a bead • Dominos

  14. Initiator • Added to polymer is called benzoyl peroxide (BPO) • Over the counter acne medicine • Different purpose in nail enhancements • BPO used to start chain reaction that leads to curing (hardening)

  15. Some monomers require more BPO than others • Use polymer powder designed for use with monomer liquid • Using wrong powder can create enhancements that are not properly cured • Could increase risk of client developing skin sensitivity or irritation

  16. Acrylic (methacrylate) Nail Enhancements using forms • Polymer powders • Many colors • Basic pink • White • Clear • Natural

  17. Used alone • Customized colors – blended • Shades of pink • Match or enhance nail beds • Bold primaries • Pastels • Wide range of designs and patterns

  18. Supplies for acrylic (methacrylate) nail enhancements • Acrylic (methacrylate) nail enhancements created by combining acrylic (methacrylate) monomer liquid with polymer powder • Acrylic (methacrylate) monomer liquid • Here’s a tip pp753 / 901

  19. Mix ratio • Amount of monomer liquid and polymer powder used to create a bead • “Dry Bead” • Equal amounts of liquid and powder • “Wet Bead” • Twice as much liquid as powder • “Medium Bead” • 50% more liquid than powder • Ideal mix ratio

  20. Typically ensures proper set and maximum durability of enhancements • Too much powder • Brittleness • discoloration • Too little powder • Weak • Risk developing skin irritation and sensitivity

  21. Acrylic (methacrylate) polymer powder • Choose color depends on methods used

  22. Nail dehydrator • Apply liberally to natural nail plate only • Avoid skin contact • Remove surface moisture and tiny amounts of oil • Both can block adhesion • Here’s a tip pp 753

  23. Nail primer • Acid-based primers (methacrylic acid) • Corrosive to skin • Potentially dangerous to eyes • Not used much nowadays • “Acid free” and “nonacid” primer developed in wide use today • Caution box pp 754 • Read mfg directions • Refer to MSDS for safe handling recommendations and instructions

  24. Acid-based primers • Relatively dry brush • Using a light dotting action • Carefully dab the brush tip to center of properly prepared nail • Primer will spread out and cover nail plate • Avoid product running into skin • Causing burns/injuries • Read mfg. suggested use and precautions

  25. Non-acid and acid-free nail primers • Slightly damp brush • Ensure nail plate is completely covered • Avoid too much product • Running onto skin • Causing skin irritation/sensitivity • Treat 2 -3 nails before dipping back into container • Read mfg suggested application procedures and precautions

  26. abrasives • Medium grit • 180 – 240 • Natural nail prep and shaping • Smoothing • Fine grit • 350 or higher • buffing • 3 way buffer • Create shine for no polish

  27. Coarser grit • Lower grit • Avoid using • Can damaged fresh nail enhancement • Acrylics can take 24 – 48 hours till peak strength

  28. Nail Forms • Placed under free edge • Used to extend nail enhancements beyond fingertip • Creates additional strength • Extra boxes on PP 902 - 903

  29. Nail tips • Pre-formed extensions • Wide variety • Shapes • Styles • colors

  30. Nail Adhesive • Cyanoacrylate monomers • Each types uses different customized additives to enhance • Set times • Strength • Other properties • Small size bottle • Short shelf life • 6 months after date of purchase • Depends on storage and usage

  31. Obtain maximum shelf life • Close cap securely • Set upright • Store out of direct sunlight • Room temperature - 60º - 85º • Nail adhesive may harden in tube and need to be thrown away

  32. Dappen dish • Poured into special holder • Monomer • Polymer • Small narrow openings – minimize evaporation • Do not use open-mouthed jars or containers with large openings • Must be covered with a tightly fitting lid when not in use

  33. NEVER pour unused portion back into original container • contaminated • Avoid skin contact with monomer to avoid skin sensitivity or irritation • Wipe clean with acetone • Store in a dust free location

  34. Nail Brush • Sable hair • Synthetic/less expensive brushes do not pick up monomer or do not release liquid properly • Avoid overly large brushes – • Hold excessive amount of liquid • Risk touching client’s skin with monomer • May increase risk of developing skin irritation or sensitivities

  35. Safety eyewear • Protect eyes from flying objects • Accidental splashes

  36. Dust masks and protective gloves • Dust masks • Worn over nose/mouth to prevent inhalation off excessive amounts of dust • Provide NO protection from vapors • Gloves

  37. Acrylic (methacrylate) nail enhancements pre-service • Complete pre-service sanitation and disinfection procedure (ch. 25, pp672/817) • Wash implements • Rinse implements • Immerse implements • Wash hands with liquid soap • Rinse and dry implements • Set up standard manicuring table

  38. Greet client and direct to wash hands with liquid soap and warm water • Perform client consultation

  39. Application of acrylic (methacrylate) nail enhancements using forms • Pages 757 – 761 • FYI pp762 • Pages 912 - 915

  40. acrylic (methacrylate) nail enhancements post-service • Make another appointment • Take-home product recommendation • Clean up around table • Clean brush • Store acrylic products • Discard used materials • Clean table - clean and disinfect implements and multiuse tools

  41. acrylic (methacrylate) nail enhancements over nail tips or natural nails • Pages 763 – 766 • Caution box pp766 • Pages – 908 - 911

  42. Maintenance and removal of acrylic (methacrylate) nail enhancements • Regular maintenance prevents nail enhancements from lifting or cracking • If lifting/breaking greater risk of infection and other problems • Full and proper rebalance must be performed every 2 – 3 weeks

  43. rebalancing • Method for maintaining the beauty, durability, and longevity of artificial nail enhancements • Do not let clients go too long without proper rebalance - more repairs • Nail is thinned down –apex of nail removed – entire nail enhancement reduced in thickness • Procedure pages 768 – 769 / 916 - 918 • Caution box page 769 / 917

  44. Crack repair • Addition of enhancement product to repair cracks • Similar procedure to rebalance • Procedures – page 770 / 919 - 920

  45. removal • Perform as soon as possible after request is made • Procedure pp771 921 - 922 • Condition surrounding skin with nail oil/lotion
