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.

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.

Growth and characterization of butyl 4-hydroxybenzoate single crystal by vertical Bridgman technique for third order nonlinear optical applications[Reference:
WebLink]
In order to improve the antimicrobial activity of paper, the antimicrobial activity of the paper manufactured with the kraft pulp which was treated with laccase/buty1 4-hydroxybenzoate was evaluated.
METHODS AND RESULTS:
The experimental results showed that, the handsheet paper containing laccase and Butyl 4-Hydroxybenzoate showed a greater efficiency against the growth of bacteria, which resisted s.aureus, bacillus subtilis, e.coli, salmonella to 94.50%, 90.87%, 98.99%, and 99.12% respectively. There was little change of anti-bacteria effect of the handsheet paper after washing four times, which indicated that the chemical bonds between Butyl 4-Hydroxybenzoate and fibers probably were formed in the presence of laccase.
CONCLUSIONS:
After the enzymatic treatment, kappa number increase compared with the control sample, and the observation of scanning electron microscope(SEM) indicated that fibers treated by laccase and Butyl 4-Hydroxybenzoate were agglutinated together in wide area, which indicated that the phenol compounds may be linked to the surface of fibers by covalent bond to some extent.
