Applications |
|
|
◆ |
With its broad spectrum of activity, good solubility in water and low acute toxicity, Preventol D 7 is a versatile preservative which is easy to use. |
|
|
◆ |
Preventol D 7’s spectrum of activity covers bacteria, including formaldehyde-resistant species, fungi, yeast and algae. |
|
|
◆ |
Preventol D 7 can be incorporated at any stage of the production process but is best added to the feedwater first. If higher Temperatures(>40℃)or pH(>9) Values are likely to occur during the manufacturing process, the product should be added at the end of the process, however. In this case take care to homogeneously distribute the preservative within the product to be protected. Because of its low viscosity, Preventol D 7 can be used undiluted or with water added. |
|
|
◆ |
The product can also be pre-dissolved in alcohols or alcohol/water mixtures. The use of Preventol D 7 in the preservation of aqueous formulations does not generally cause any undesirable side-effects. In contrast to preservatives containing active ingredients which split off formaldehyde, Preventol D 7 is highly suitable for the preservation of products which contain protein (e.g.casein).
|
|
|
◆ |
It is advisable to carry out compatibility tests before Preventol D 7 is used in new products or applications. |
