What is Isopropyl Alcohol? Isopropanol (IPA) is a secondary alcohol that has become indispensable in cosmetics and households. It is a clear, colorless liquid with a characteristically sharp odor. Unlike ethanol, it is mostly produced synthetically. Its superpower lies in its volatility: It evaporates in seconds without leaving any residue, making it the ideal cleaner.

Isopropanol is the gold standard when it comes to sterility. It is effective against bacteria, fungi, and many viruses.

• Tool Disinfection: Ideal for cleaning cosmetic tools such as tweezers, scissors, or brushes.
• The 70% Rule: For disinfection, a dilution to 70% (with 30% water) is more effective than 99%, as the water helps penetrate the bacterial cell walls.
• Nail Care: Before modeling or painting, it degreases the natural nail ("dehydrator") so that the polish adheres better.

Besides disinfection, IPA is an extremely strong grease solvent. It removes residues that water and soap fail to tackle.

The core competencies of IPA:

• Dissolves stubborn adhesive residues (e.g., from labels) and color traces.
• Cleans glass surfaces and mirrors absolutely streak-free.
• Removes the "sweat layer" (inhibition layer) from UV gel nails and ensures high gloss.
