STORAGE AND HANDLING of Protectol PE:
Keep Protectol PE container tightly closed.
Store Protectol PE in a cool, dry place away from direct sunlight.
At temperatures below 9°C, Protectol PE may solidify, if this happens heat gently (max. 60°C), shake to homogenize.
Storage of Protectol PE:
Phenoxyethanol products are very stable over a wide pH and temperature range.
Raised temperature storage trials have shown that there was no indication of instability even when stored at temperatures of up to 50 °C for 12 months.
Under normal storage conditions shelf life of Protectol PE is 2 years.
Protectol PE should be stored at ambient temperature in sealed containers as supplied, in dry conditions.
For bulk storage, phenoxyethanol products may be stored in tanks constructed of normal carbon steel (e.g. A283 grade) or stainless steel (e.g. AISI TP 321).
Protectol PE is recommended that the products are stored under a blanket of dry nitrogen.
If exposed to atmospheric oxygen, a small amount of decomposition may occur, the breakdown products being aldehydes and acids.
This process can be accelerated by humidity resulting in a deterioration of quality, especially over long storage periods.

Case Study:
Protectol PE is commonly used in Metal Working Fluids (MWF) to protect the diluted fluid from microbial spoilage during usage.
The following study was carried out to demonstrate the efficacy of Protectol PE in this application area.
The method used is an adaptation of the IBRG MWF Challenge Test Method to evaluate biocidal compounds in an aqueous based functional fluid.
A supplied Metal Working Fluid Concentrate was diluted to use levels (5% w/w).
One part of this dilution was dosed with Protectol PE at 1% while the other part was used unpreserved as control.
Three different inocula were used in separate tests.
On the one hand a mixed aerobic bacterial inoculum was used prepared from cultures of Alcaligenes faecalis, Shewanella putrefaciens, Pseudomonas aeruginosa and Citrobacter freundii containing 108 cfu/ml each.
As a second inoculum a mixed fungal suspension of 107 cfu/ml was used prepared from cultures of Rhodotorula rubra, Acremonium strictum and Fusarium solani.
A mycobacterial inoculum prepared from a culture of Mycobacterium chelonei was used as well (107 cfu/ml).
Aliquots of the preserved and the unpreserved diluted Metal Working Fluid were inoculated with each of the inoculi in separate samples (1:100 dilution resulting in a final germ load of 105 cfu/ml) and incubated for 7 days at room temperature.
After 7 days the current microbial load was determined and the samples were reinoculated until three challenges were achieved.
To determine the microbial load, the samples were streaked out on specific recovery media and incubated at relevant temperatures.
The growth was assessed using the rating system described below.
In accordance with the criteria described in the IBRG method, “control of microbial challenges” is defined as protecting the diluted working fluid from microbial spoilage for at least one more challenge than the inoculated control samples while the term “Protection” is defined as achieving a subjective score of 0 or 1 when the control has a subjective score of >2.
