Formulation view Built on ethyl acetate and denatured alcohol volatiles, this formula uses nitrocellulose as the primary film-former, reinforced with tosylamide/epoxy resin for adhesion. Polyvinyl butyral adds hardness, while dimethicone ensures smooth application. The design balances rapid drying with glossy durability for professional manicure scenarios. Factory perspective highlights precise solvent ratio control to manage drying speed versus film flexibility, preventing brittleness.

Ingredients explained
- Ethyl Acetate
- Organic solvent/fragrance carrier, fast evaporation; ventilation needed during production
- Alcohol Denat
- Denatured ethanol; solvent, penetration enhancer, and quick-dry agent; high % may compromise barrier in dry skin.
- Sd Alcohol 40-B
- Denatured solvent for fragrance/oil dilution, contains trace isopropyl thiol (sensitizer), irritating at high levels
- Butyl Acetate
- Volatile solvent and fragrance; has distinct odor, used as diluent, high levels can irritate nasal passages.
- Heptane
- Volatile solvent for spray or quick-dry systems; flammable, require packaging and storage compliance.
- Nitrocellulose
- Film former for nail/gel products; insoluble in water, requires organic solvents, flammable.
- Tosylamide/Epoxy Resin
- Film-forming plasticizer for water-resistant makeup; heat-sensitive, check sensitization risk.
- Isopropyl Alcohol
- Alcohol solvent at 1–10%; fast-evaporating, high levels may cause dryness/irritation
- Trimethyl Pentanyl Diisobutyrate
- Trimethyl pentane diisobutylate; plasticizer and solvent; improves product flexibility; low toxicity, no known allergen data.
- Polyvinyl Butyral
- Film-forming polymer for hair or nail lacquers, providing gloss and adhesion; poor water solubility, match specific solvent systems.
- Camphor
- Denaturant and fragrance with irritant and allergenic potential; strict concentration limits required for sensitive skin.
- Benzophenone-1
- Not decoded yet
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Ci 17200
- Acid Red 33 hair dye; restricted use, potential scalp irritation
- Ci 60725
- Solvent Violet 13 synthetic dye; restricted in certain products, potential allergen, strict regulatory compliance needed.
