| Property | Value / Note |
|---|---|
| Composition | Proteins produced by fermentation (e.g. protease, amylase, lipase, cellulase). Often supplied in granulated or liquid stabilized form. |
| Physical properties | Non-volatile; dusts may become airborne during handling or drying; readily denatured by heat or extreme pH. |
| Odour | Mild organic / fermentation odour; not an indicator of concentration. |
| Stability | Stable under cool, dry conditions. Sensitive to heat, oxidants, and strong acids/alkalis. |
| Typical sources | Detergent manufacture, bio-ethanol or food fermentation exhaust, enzyme formulation or spray-drying plants. |
*Properties are typical for enzyme preparations; always verify via supplier SDS and exposure assessment data.
