Which ingredient is commonly used as a film-former in nail polish?
Polyethylene glycol
Polylactic acid
Polyurethane
Nitrocellulose
Nitrocellulose is the primary film-forming agent in most nail polishes. It forms a smooth, durable film that holds pigment on the nail.
What is the primary function of a base coat in a manicure?
Adds a glossy finish
Protects nails and improves polish adhesion
Cures polish under UV light
Removes cuticle debris
A base coat adheres polish to the natural nail and protects it from staining. It also improves the longevity of the manicure.
Which nail polish finish has no shine?
Metallic
Shimmer
Matte
Gloss
Matte finishes are designed to diffuse light and eliminate shine. In contrast, glossy or metallic finishes reflect light and appear shiny.
On a product label, "3-free" indicates the polish is free of which chemicals?
Formaldehyde, acetone, and camphor
Toluene, ethyl acetate, and water
Formaldehyde, toluene, and dibutyl phthalate
Dibutyl phthalate, ethanol, and silicone
"3-free" nail polishes omit formaldehyde, toluene, and dibutyl phthalate. These chemicals have been linked to health concerns and are common in older formulations.
Which product is specifically used to nourish cuticles?
Cuticle oil
Nail hardener
Base coat
Top coat
Cuticle oil is formulated to soften and nourish the cuticle area. It moisturizes the skin around the nail and promotes healthy growth.
Which solvent evaporates fastest in nail polish formulations?
Acetone
Ethylhexyl palmitate
Glycerin
Water
Acetone has a low boiling point and evaporates more quickly than water or larger molecules. This property makes it the fastest-drying solvent in polish formulas.
A client presents with brittle, splitting nails; which nail treatment is most appropriate?
Moisturizing cuticle oil
Quick-dry top coat
Protein-enriched strengthening treatment
Matte finish polish
Protein-enriched treatments supply structural building blocks to brittle nails. The added proteins help reinforce nail integrity and reduce splitting.
Which statement best indicates a product with reduced allergenic potential?
Water-based
Cruelty-Free
Alcohol-Free
Labeled "Hypoallergenic"
Products labeled "Hypoallergenic" are formulated to minimize common allergens. This designation implies testing and reformulation to reduce the risk of reactions.
What differentiates gel polish from regular polish?
Contains higher nitrocellulose content
Requires UV/LED curing to harden
Dries by air evaporation
Only used for French manicure
Gel polish cures through a photoinitiated reaction under UV or LED light. Traditional polishes dry by solvent evaporation and do not require curing lamps.
When removing gel polish, what precaution is recommended to protect the natural nail?
Soak nails in acetone no more than 15 minutes
File nails before soaking
Apply heat to speed removal
Use metal drill bits for removal
Limiting acetone soak to about fifteen minutes helps prevent over-drying and damage to the nail plate. Prolonged exposure can weaken the natural nail.
Which ingredient acts as a plasticizer in nail products to improve flexibility?
Dibutyl phthalate
Ethyl acetate
Camphor
Nitrocellulose
Dibutyl phthalate is a common plasticizer that makes the polish film more flexible. It helps reduce brittleness in the finished product.
Which nail enhancement should be avoided for clients with active fungal infections?
Strengthening treatments
Cuticle oil
Gel overlays
Topical antifungal primer
Gel overlays create a sealed environment that can trap moisture and worsen fungal infections. Clients with active infections should avoid sealed enhancements.
What does "no-wipe" refer to in gel top coats?
No wiping needed around cuticles
No sticky residue after curing
Dries without UV light
Does not require removal
No-wipe gel top coats cure to a tack-free surface without a dispersion layer. This eliminates the need to wipe off any sticky residue after curing.
A nail polish labeled "5-free" excludes five harmful chemicals. Which chemical is typically omitted in 5-free formulations but not in 3-free?
Water
Formaldehyde resin
Nitrocellulose
Ethyl acetate
Formaldehyde resin is commonly excluded in 5-free formulations but not necessarily in 3-free. It can release formaldehyde and contribute to sensitivity.
According to recommended usage, gel polishes should be allowed to cure under LED light for what duration?
2 seconds
30 seconds
5 minutes
2 minutes
Most LED gel systems require about thirty seconds of curing per layer. This ensures proper polymerization without overexposing the nail.
In acrylic nail application, what is the role of the initiator benzoyl peroxide?
Generates free radicals to polymerize monomer
Acts as a plasticizer
Provides pigmentation
functions as a solvent
Benzoyl peroxide decomposes to generate free radicals that initiate monomer polymerization. It is essential for curing the acrylic mixture.
Which finish utilizes ultrafine particles to diffuse light for a soft-focus effect?
Glossy finish
Velvet matte finish
Metallic chrome finish
Holographic finish
Velvet matte finishes contain ultrafine particles like silica that scatter light. This produces a soft-focus, nonreflective surface.
A client shows signs of allergic contact dermatitis after a nail service. Which ingredient is most likely responsible?
Methacrylates in gel products
Vitamin E oil
Water-based polish pigments
Nail buffer dust
Methacrylates used in gel and acrylic products are common sensitizers. They can trigger allergic contact dermatitis in susceptible clients.
When analyzing an MSDS for a nail primer, which information indicates potential respiratory hazard?
High viscosity
Low flash point and volatile organic compounds
Presence of iron oxide
High pH level
A low flash point combined with high VOC content signals volatile chemicals that can vaporize and be inhaled. This poses respiratory risks during application.
For long-lasting acrylic nails, what is the critical ratio of monomer to polymer powder?
Approximately 1:1 by volume
Equal weight to powder by mass
3:1 by volume
1:3 by weight
A roughly equal volume ratio of liquid monomer to polymer powder yields a workable consistency and proper polymerization. Significant deviations can weaken the enhancement.

Cheat Sheet

  2. Personalize Treatments Like a Pro - Clients have different nail strengths, style goals, and sensitivities, so a one-size-fits-all approach won't cut it. Tune into their nail health, color cravings, and allergy risks before picking a treatment. This way, you'll deliver dazzling, safe manicures every time. FDA Nail Care Guide fda.gov
  3. Decode Safety Labels - Product labels love throwing terms like "3-free" or "5-free" around, but what do they really mean? These codes reveal which harmful chemicals have been left out of a formula. By decoding them, you'll spot the safest polishes and avoid nasty surprises. Time Nail Polish Chemicals time.com
  4. Master the Formula Family - Traditional polish, gels, and dip powders all have their own perks and playtime rules. Traditional coats dry in minutes, gels need curing lamps, and dip powders bring extra durability. Get hands-on with each style to expand your nail-art playground.
