Method DIN 53160-2:2010-10 specifies an artificial perspiration solution that is used to determine the colorfastness of articles for common use. The test method is applicable to all articles of daily use, independent of the coloring procedure applied (dyeing, staining or coating). Method BS EN 1811:2011 is used for the testing of nickel release from jewelries and other products that come with prolonged contact with skin. The primary perspiration components and pH described by methods BS EN 1811:2011 and DIN 53160-2:2010-10 are the same, we now offer a buffered version of the original formulations. Phosphate ions do not affect color migration rates nor the rate of nickel release, so these modified formulations can be used for the same tests. The buffered formulation is offered at pH 6.5, specified by DIN 53160 and BS EN 1811:2011 methods. Stabilized formulations contain a preservative to prevent bacteria growth and can be stored at room temperature. This solution is Buffered

This artificial saliva formulation has a mineral composition and pH close to human saliva. Mucin is added to increase the viscosity and lubricating ability of the artificial saliva. This solution can be used for dental, drug delivery or pharmaceutical studies. The two-part non-stabilized formulation comes with dry pre-weighted mucin powder to be mixed in before use. Non-stabilized solution should be stored refrigerated. The pH of the formulation is 6.8. Amylase is the main enzyme in human saliva and is needed for starch digestion. As some applications require studying the effect of enzymes in saliva, Pickering Laboratories offers an easy way to add biological activity to your chosen artificial saliva product. Once added to the 200 mL bottle of artificial saliva, our Amylase product will provide 80 U/mL of enzyme activity
