        应         用
          With its broad spectrum of activity,good solubility in water and generally good compatibility, Preventol IT 14 is a versatile preservative which is easy to use.
          Preventol IT 14’s spectrum of activity covers bacteria, including formaldehyde-resistant species, fungi, yeast and algae.
          Preventol IT 14 can be incorporated at any stage of the production process but is best added already to the feedwater. If higher temperatures (>40℃)or pH values(>9)are likely to occur during the manufacturing process, the product should be added at the end of the process. However,in this case care should be taken to distribute the preservative homogeneously within the product to be protected to ensure an even effect. Because of its low viscosity, Preventol IT 14 can be used undiluted or with water added. It can also be pre-dissolved in alcohols or alcohol/water mixtures.
          The use of preventol IT 14 in the preservation of aqueous formulations does not generally cause any undesirable side-effects. In contrast to preservatives which contain active ingredients that release formaldehyde, Preventol IT 14 is ideal for preserving products containing proteins(e.g.casein).
          Before Preventol IT14 is used in new products or application, it is advisable to carry out compatibility trials and test ist microbiological effectiveness.
