Texture analysis in action: Finding new ways to measure stickiness

Stickiness is a major consideration for manufacturers of certain products. Whilst stickiness can be a desired property for certain products it can also be an unattractive sensorial property that can be very off-putting for consumers. However, it is a simple property to measure and that is where a Texture Analyser comes in.

Recently in the lab we have been expanding the application of a rig that was originally designed for the measurement of nail polish adhesion. During the test, a channel 20cm long is filled with the sample to a depth of 0.5 mm and 5-10 adhesion tests are performed at points along this channel. The probe is held on the surface of the sample at 750g for 5 seconds to allow a bond to form between the probe and sample before withdrawing quickly and measuring the stickiness (the force to separate the two surfaces) and stringiness (the distance/time pulled away before separation occurs). The ability to prepare a sample and test it in several different regions along its length increases sample throughput – a particularly important factor in sample testing efficiency.

Typical curve and annotation of analysis using this method

We found that this rig could be successfully expanded to provide great comparison and development of the following tested products which are now available as application studies and sample projects in the latest version of Exponent and Exponent Connect software.

• Comparison of the adhesive properties of handcream, body butter, Vaseline and moisturising cream

• Comparison of the adhesive properties of icing, caramel sauce and buttercream

• Measurement of the adhesive properties of lip gloss samples and petroleum jelly

• Comparison of the adhesive properties of hair wax, gel and pomade
