This is the energy required to overcome the strength of the internal bonds within the sample.1 business day. The area under the graphs is a measure of the work done to penetrate the samples. From Figure 1, Sample A is significantly harder than Sample B. The higher the peak force value, the harder the sample. The highest peak value then becomes the force required to penetrate the sample to the specified distance.

When a trigger force of 10 g is achieved, the probe begins to penetrate the sample to a defined distance (e.g., 8 mm) at a set speed of 2mm/s. The soap penetration test can also indicate whether there are trapped air bubbles or a grainy texture seen as fluctuations in force as the probe comes into contact with air bubbles or hard particles.įigure I A graph comparing the hardness of two different bar soap formulations tested at 20 oC. Test temperatures must therefore be reported in the results. The penetration test can also monitor hardness over temperatures that the soap may be subjected to during transportation and storage. Consequently, for comparison purposes, penetration distances must always be reported. In addition, resulting hardness values will increase relative to the increased penetration depths. The penetration distance can be modified however, the target distance chosen should be such that the probe does not touch the base of the container otherwise the instrument will be overloaded. This will ensure that the force capacity covers the range for other future samples. The firmest sample is better tested first in order to anticipate the maximum testing range required for subsequent samples. For comparison purposes, samples should be placed into the confectionary jig in the same orientation. If the chosen bar soap is curved, use a sharp blade (knife) to flatten the testing surface if necessary. After each test, clean the cylinder probe before proceeding to the next test.Lower the probe to about 5 mm above the confectionary jig.Any further tightening will compress the sample. Tightening should be to the point of first resistance from the sample.

Put the sample into the confectionary jig such that it is centrally aligned to the aperture of the fixture then tighten into position using the four screws.Once the alignment is complete, tighten the thumb nuts of the fixture base table.Align the aperture of the confectionary jig to the probe above by repositioning the base table and ensure that the probe can penetrate the aperture of the confectionary jig without friction effects with the sides of the jig.Place the confectionary jig onto the fixture base table and tighten into position using the side screws.Place the fixture base table onto the base of the instrument and loosely tighten with the thumb screws to enable some degree of mobility.Attach the 2 mm cylindrical probe onto the instrument.Remove the samples from storage and allow the samples to equilibrate to the testing temperature (room temperature in this case). TA-CJ - Confectionary Jig, TA-BT-KIT- Fixture Base Table Results are influenced by product formulation. The penetration test is an Empherical test for the ease of penetration of soap.
