In this free webinar, Dr Xuzi Kang (Postdoctoral Fellow, TRI Princeton) will describe several measurement techniques recently developed at TRI to evaluate the performance of lipsticks. She will explain how these methods can be used to substantiate product claims, and set your brand apart.
 

This presentation will describe tests that can measure the properties of the lipstick stick itself (hardness, stickiness and melting behaviour), lipstick spreadability (pay-off and layering friction), colour effects, and, lipstick transfer and longevity.
 

The care of the lips and prevention of dryness and cracking is always an important consumer need.  This presentation will, therefore, also describe the tests available to measure lip hydration, based on spectroscopy and on skin electrical impedance measurements. The pros and cons of these approaches will be discussed.
