Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com
The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Antimicrobial effect of trans-cinnamaldehyde, (-)-perillaldehyde, (-)-citronellal, citral, eugenol and carvacrol on airborne microbes using an airwasher.[Pubmed:
17077531 ]
METHODS AND RESULTS:
Citral, trans-cinnamaldehyde, (-)-Perillaldehyde, (-)-citronellal, eugenol and carvacrol were tested for their influence on microbial count in air by vaporizing with an air washer. The highest antibacterial activity was observed when (-)-Perillaldehyde was sprayed. The average reduce of germ count was 53%. On the other hand, the antimicrobial activity of eugenol was the lowest of these six compounds.
The average reduction of germ count was 13%. When water without volatile compounds was sprayed, the colony forming units increased.
CONCLUSIONS:
These results suggest the utility of selected aroma-compounds for the control of bacteria in the room.

Terpenoid biotransformation in mammals. V. Metabolism of (+)-citronellal, (+-)-7-hydroxycitronellal, citral, (-)-perillaldehyde, (-)-myrtenal, cuminaldehyde, thujone, and (+-)-carvone in rabbits.[Pubmed:
2815827 ]
METHODS AND RESULTS:
1. The metabolism of (+)-citronellal, (+-)-7-hydroxycitronellal, citral, (-)-Perillaldehyde, (-)-myrtenal, cuminaldehyde, thujone, and (+-)-carvone was studied in rabbits. 2. In (+-)-7-hydroxycitronellal,
(-)-Perillaldehyde , (-)-myrtenal and cuminaldehydes, both primary alcohols and carboxylic acids were formed. 3. In (-)-citronellal and citral, regioselective oxidation was found and a trans-positioned methyl group was carboxylated in each case. 4. In o-cuminaldehyde, reduction but not oxidation, was found.
