Texture Analysis in Action: the Eye Shadow Test

Eye Shadow test using the TA.XTplus Texture Analyser The EYE SHADOW TEST uses standard Cylinder Probes P/2 – P/6 to perform a puncture test on the pressed tablet form of eyeshadow, which is today probably the most popular form of this product.

An essential purpose of binders, and other raw ingredients, is to provide stability to the tablet to prevent it from crumbling, flaking and dusting both during shipment and use. This property is judged by measuring the hardness or ‘cake strength’ of the tablet by penetration tests.

Selection of the various ingredients and their respective quantities is dictated by their ability to aid in compression of the tablet (that is, how easily they pack together) and prevent its crumbling, whilst providing a soft feel on the skin and contributing to adherence to the eyelid.

Such properties are similar to those necessary for formulation of compressed face powders.The test shown above can indicate the presence of air pockets beneath the sample surface, which may be undesirable, and the optimal pressing time and weight.
