1. Fixatives are used to preserve and protect artwork, drawings, and sketches from smudging, fading, or deteriorating over time.
2. Fixatives come in various forms such as aerosol sprays, pump sprays, and liquid solutions.
3. Fixatives create a protective barrier over the surface of the artwork, preventing the media from being easily disturbed or rubbed off.
4. Fixatives can enhance the colors and vibrancy of the artwork, making it appear more vivid and long-lasting.
5. Fixatives are typically transparent and do not alter the appearance of the artwork or change the texture of the surface.
6. Fixatives are quick-drying and easy to apply, allowing artists to work efficiently and effectively.
7. Fixatives are non-toxic and safe to use, making them suitable for all types of artwork and artists.
8. Fixatives can be easily removed with solvents or erasers if needed, allowing for corrections or adjustments to be made to the artwork.

Properties of a Fixative:
1. Penetration and Distribution:
- Ability to infiltrate and distribute evenly throughout the tissue to ensure complete fixation.
- Rapid fixation rate to prevent tissue autolysis and denaturation.
2. Protein Cross-Linking:
- Reacts chemically with tissue proteins to form cross-links, preserving their structure and preventing degradation.
- Covalent bonds provide stability and resistance to solubilization.
3. Preservation of Morphology:
- Maintains the structural integrity of cells and tissues, preventing distortion or shrinkage.
- Preserves the relationship between different tissue components.
4. Irreversibility:
- Once fixed, tissues become permanently preserved and cannot be rehydrated or returned to their original state.
- Irreversible cross-linking ensures the permanence of the fixed sample.
5. Chemical Compatibility:
- Compatible with subsequent processing techniques, such as staining, immunohistochemistry, and nucleic acid analysis.
- Should not interfere with downstream analyses or alter the chemical composition of the tissue.
6. Toxicity and Safety:
- Should not pose significant health risks to the user or the environment.
- Proper handling and disposal are necessary to minimize potential hazards.
7. Convenience and Efficiency:
- Easy to use, with minimal preparation or special equipment required.
- Efficient in terms of time and resources, allowing for rapid tissue fixation.
