Determining The Water Content in Hand Cream
Application note L 492 provides a method for determining the water content in hand cream (hand balm). The properties of this sample did not permit a determination of the water content under standard working conditions. The sample was not sufficiently distributed and it was impossible to detect the sample water completely. Parts of the sample coated the indicator electrode and interfered with the endpoint indication. Various tests showed that heating the medium in the titration vessel improved the distribution of the sample.
