Cyclohexylamine can be used as a synergist in fragrance manufacturing to improve the release effect of fragrance.
3.3.1 Improve aroma release
Cyclohexylamine can react with aroma components in flavors to generate compounds with higher volatility and improve the release effect of aroma. For example, amine compounds produced by the reaction of cyclohexylamine with alcohols in fragrances are more volatile and can release fragrance faster.
Table 3 shows the application of cyclohexylamine in aroma release.
| Fragrance type | No cyclohexylamine used | Use cyclohexylamine |
|---|---|---|
| Water-based fragrance | Release Effect 3 | Release Effect 5 |

| Solid flavor | Release Effect 3 | Release Effect 5 |
3.4 As a preservative
Cyclohexylamine can also be used as a preservative in flavor manufacturing to prevent microbial contamination of flavors during storage.
3.4.1 Anti-corrosion effect
Cyclohexylamine has certain antibacterial properties, which can prevent the deterioration of flavors during storage by inhibiting the growth of microorganisms. For example, cyclohexylamine can effectively inhibit the growth of bacteria and mold and extend the shelf life of flavors.
Table 4 shows the application of cyclohexylamine in antiseptic effect.
| Fragrance type | No cyclohexylamine used | Use cyclohexylamine |
|---|---|---|
| Water-based fragrance | Anti-corrosion effect 3 | Anti-corrosion effect 5 |
| Solvent-based fragrance | Anti-corrosion effect 3 | Anti-corrosion effect 5 |
| Solid fragrance? | Anti-corrosion effect 3 | Anti-corrosion effect 5 |
