1. Chemical Formula: C6H14O3
2. Molecular Weight: ~134.17 g/mol
3. Appearance: Clear, colorless liquid
4. Odor: Mild, pleasant odor
5. Boiling Point: ~202°C
6. Flash Point: ~96°C (closed cup)
7. Density: ~0.99 g/cm³ at 20°C
8. Solubility: Miscible with water and many organic solvents
9. Viscosity: Low viscosity, making it an excellent flow enhancer

Applications:

1. Cleaning Agents:

• Household and Industrial Cleaners: Acts as a solvent for grease, oils, and resins.
• Glass Cleaners: Provides streak-free drying due to its low evaporation rate.
• Metal Degreasers: Effective for removing oils and contaminants from surfaces.

2. Paints and Coatings:

• Coalescing Agent: Enhances film formation and durability in waterborne coatings.
• Solvent: Used in paints, varnishes, and lacquers to improve flow and leveling.

3. Personal Care and Cosmetics:

• Solubilizer: Used in hair sprays, perfumes, and lotions to dissolve active ingredients.
• Humectant: Retains moisture and prevents drying in formulations.

4. Textile and Leather:

• Acts as a dye carrier and solvent in textile and leather processing, ensuring even penetration and vibrant colors.

5. Inks and Printing:

• Used in printing inks for enhanced drying and consistent print quality.

6. Agrochemicals:

• Solvent for pesticide and herbicide formulations due to its high solvency.

7. Pharmaceutical Applications:

• Occasionally used as a carrier or solvent in certain pharmaceutical formulations.

Handling and Safety:

Hazards:

1. Low Toxicity: Considered relatively safe but can cause mild irritation to the skin, eyes, or respiratory system if exposed.
2. Flammability: Combustible liquid. Keep away from open flames or high heat sources.

Personal Protective Equipment (PPE):

• Gloves: Chemical-resistant gloves (e.g., nitrile or rubber).
• Eye Protection: Safety goggles or face shield.
• Respiratory Protection: Use in a well-ventilated area or wear a respirator if exposure limits are high.

Storage:

• Store in a cool, dry, and well-ventilated area.
• Use tightly sealed containers, preferably stainless steel or HDPE.
• Keep away from heat, sparks, and open flames.

First Aid:

1. Inhalation: Move to fresh air; seek medical attention if symptoms persist.
2. Skin Contact: Wash with soap and water.
3. Eye Contact: Flush eyes with plenty of water for 15 minutes. Seek medical attention if irritation persists.
4. Ingestion: Rinse mouth with water. Do not induce vomiting; seek immediate medical attention.

Advantages:

1. High Solvency: Dissolves a wide range of materials, including oils, greases, and resins.
2. Low Evaporation Rate: Ideal for applications where controlled drying is necessary.
3. Wide Compatibility: Miscible with water and organic solvents, enhancing its versatility.
4. Eco-Friendly: Biodegradable and less toxic than many alternative solvents.

Dilution and Usage:

• Can be diluted with water or other solvents as required for specific applications.
• Always mix slowly to avoid splashing or uneven dispersion.
