CHAPTER 20 — CHEMISTRY FOR NAIL PRODUCTS
Louisville Beauty Academy (LBA) — YES I CAN™ Understand the Science Behind Safe, Beautiful Nails
Chemistry is the engine behind everything we do:
- acrylic sets because of chemical reaction
- gel cures because of light energy
- polish dries because of evaporation
- adhesive bonds because of chemical attraction
At Louisville Beauty Academy, we teach:
“When you understand chemistry, you control your craft.”
This chapter turns complicated chemistry into simple, clear, student-friendly knowledge.
🔥 SECTION A — ACRYLIC CHEMISTRY (Liquid & Powder)
Acrylic systems involve two parts:
1. Monomer (Liquid)
Meaning: Liquid chemical that reacts with powder.
Sentence: “Monomer must be used with correct ratio for strength.”
LBA Tip: Liquid part.
2. Polymer (Powder)
Meaning: Acrylic powder made of pre-formed polymers.
Sentence: “Polymer combines with monomer to form the nail enhancement.”
LBA Tip: Powder part.
How Acrylic Works (Simple Explanation)
✔ Monomer liquid + polymer powder
✔ Brush picks up bead
✔ Chemical chain forms (polymerization)
✔ Hardens into durable structure
This is NOT drying — it is a chemical reaction.
Acrylic Ratio (VERY IMPORTANT)
Correct Ratio = Strong Nail
- Bead is smooth
- Bead is workable
- Enhancement lasts
Too Wet = Weak, Lifts Easily
- Runs
- Bubbles
- Allergies risk increases
Too Dry = Crumbles / Breaks
- Won’t stick
- Grainy
LBA teaches:
“Perfect ratio = perfect chemistry.”
⚡ SECTION B — GEL CHEMISTRY (UV/LED Curing)
Gels do NOT “dry.”
They cure when exposed to specific light wavelengths.
1. UV Gel
✔ Cures with UV light
✔ Slower but deep cure
✔ Used for builders & overlays
2. LED Gel
✔ Cures faster
✔ Uses LED wavelength
✔ Many modern gels are LED-compatible
How Gel Cures (Simple)
✔ Light → activates photoinitiators
✔ Photoinitiators → start curing reaction
✔ Gel → becomes solid
Oxygen Inhibition Layer
Meaning: Sticky layer after curing.
Sentence: “This layer is normal — don’t remove until top coat.”
LBA Tip: Do NOT wipe between layers unless instructed.
Heat Spikes in Gel
Meaning: Sharp heat during curing.
Reason: Reaction too fast.
Fix:
✔ Use thinner layers
✔ Flash cure
✔ Lower heat lamp mode
LBA says:
“Thin layers cure safely.”
💅 SECTION C — POLISH CHEMISTRY
1. Nail Polish
Dries by evaporation
✔ Solvents evaporate
✔ Resin + pigment remains
2. Base Coat
✔ Helps adhesion
✔ Prevents staining
3. Top Coat
✔ Protects polish
✔ Adds shine
✔ Seals free edge
🧲 SECTION D — ADHESIVES (Nail Glue, Resin, Gel Adhesive)
1. Nail Glue (Cyanoacrylate)
Meaning: Fast-bonding adhesive.
Use: Tips, quick fixes.
Avoid: Skin contact.
LBA Tip: Fast glue.
2. Resin
✔ Thicker adhesive
✔ Used with activator
✔ Stronger than glue
3. Gel Adhesive
✔ Thick, slow-setting
✔ Used for rhinestones & attachments
✔ Cures with lamp
🧼 SECTION E — PRODUCT SAFETY & ALLERGY PREVENTION (LBA PRIORITY)
Chemicals can cause allergies if used incorrectly.
LBA teaches students to avoid:
❌ Oversaturation of monomer
❌ Touching skin with gel or acrylic
❌ Pools of uncured gel
❌ Uncured gel under enhancements
❌ Using MMA monomer (illegal in Kentucky & most states)
❌ Mixing brands without knowledge
❌ Working in poorly ventilated areas
Allergy Warning Signs
✔ Itching
✔ Redness
✔ Swelling
✔ Blisters
✔ Peeling skin
If ANY appear → STOP SERVICE.
Say:
“For your safety, we cannot continue. Please see a medical professional.”
🧪 SECTION F — PRODUCT COMPATIBILITY
Mixing different brands can cause:
- lifting
- burning
- poor adhesion
- cracking
- improper curing
- allergies
At LBA we say:
“Same brand = safer chemistry.”
🛑 SECTION G — AVOID MMA (Methyl Methacrylate)
Illegal in many states
Too strong for natural nails
Causes:
❌ Allergies
❌ Permanent nail damage
❌ Natural nail tearing
❌ Over-strong adhesion
Use EMA monomer only.
🧼 SECTION H — STORAGE & HANDLING OF CHEMICALS
✔ Keep containers closed
✔ Avoid sunlight
✔ Store cool & dry
✔ Keep SDS documents
✔ Label everything
✔ Use small amounts at a time
✔ Ventilate workstation
❤️ LBA HUMANIZATION APPROACH™ — CHEMISTRY WITH CARE
Products are powerful.
Your hands bring them to life with intention and love.
At Louisville Beauty Academy, we teach:
✔ Respect chemicals
✔ Use correct amounts
✔ Practice safe application
✔ Protect client’s skin
✔ Follow manufacturer rules
✔ Keep everything clean
✔ Never rush reactions
Say it:
YES I CAN™ understand product chemistry.
YES I CAN™ avoid allergies and protect clients.
YES I CAN™ apply safely and professionally.
Soon I WILL say: I HAVE DONE IT™.”
