Texture Analysis in Action: the Sachet/Tube Extrusion Rig

Toothpaste extrusion test using the TA.XTplus Texture Analyser
The SACHET/TUBE EXTRUSION RIG (A/STE) is a device which extrudes the contents of sachet and tube style packaging.

It has been designed to allow manufacturers of pharmaceutical, cosmetic and personal care products to quantify the ease of removal and application of products such as ointments, creams and gels.

The rig positions the product vertically between two rollers, clamping the closed end with a grip at the top. The grip then pulls the sachet/tube upwards through the rollers, forcing the contents out whilst measuring the force required.

Product developers can analyse changes in a product’s consistency throughout its shelf-life and adapt formulations accordingly whilst also enabling manufacturers to assess the suitability of packaging material and its construction.

Some more information on this fixture
A large proportion of cosmetic products are now being produced in sachet or tube portions for the provision of smaller quantities of cosmetics for the purpose of travelling or to provide as samples.

For products in tubes, such as foundations, the ability to squeeze the product out effectively is essential and is fundamental to its ease of removal from the packaging when required. If the substance is too dense, consumers will experience difficulty extracting it; if it is too fluid, the product could leak. The higher the force recorded during the test, the more difficulty a consumer would experience in squeezing out the required amount.

Such a test at an early stage of production could spell the difference between a successful and appealing product and one which will destroy the possibility of upgrading from sample sachet to long-term purchase of the high value larger volume cosmetic product. For manufacturers, failure at the last hurdle would bring disappointment and huge material losses.

We can design and manufacture probes or fixtures
for the TA.XTplus texture analyser that are bespoke to your sample and its specific measurement.

Once your measurement is performed, our expertise in its graphical interpretation is unparalleled. Not only can we develop the most suitable and accurate method for the testing of your sample, but we can also prepare analysis procedures that obtain the desired parameters from your curve and drop them into a spreadsheet or report designed around your requirements.
