Requirement

Barry M Cosmetics Ltd are the leading British colour cosmetics brand, offering a comprehensive range of lipsticks and lip paints.

The company is famous for on trend innovation – bright colours, even colour changing, plus naturals, in a choice of finishes from matte to satin—all with the Cruelty-Free formulation/ingredients pledge.

These products must provide a smooth flow onto the lips for application control and an expensive-feeling moisture-rich quality texture, whilst delivering a long-lasting effect and skin protection.

The solid bullet’s material properties need to be resilient and durable under application stresses – typically a cantilever bending load.

Barry M’s skilled cosmetics product designers and formulation chemists needed a quick and straightforward breakage test procedure with clear, immediate results for R&D and QA purposes.

Solution

Lipstick bullet fixture and motorised test stand enables one button compression testing.

Simple test process indicates peak load at failure to enable innovative products to be routinely back-to-back tested with existing successful lines

Mecmesin supplied a MultiTest 2.5-d motorised test stand with an AFG digital force gauge – the ideal configuration for quick and straightforward routine compression testing.

The test stand is compact for a laboratory benchtop and the 50 N capacity of the gauge enables optimum accuracy for the load range expected. The gauge and the stand communicate seamlessly for control and ease-of-use.

Mecmesin’s custom lipstick fixture securely holds the test sample horizontally, perpendicular to the smooth, flat-tipped probe’s loading direction. The lipstick is therefore bent, not cut, although the material may fail in shear, which would be valuable information.

This gripping solution also enables contact at a repeatable distance along the bullet, which is most vulnerable when new - at its initial maximum length - the worst time for the customer to experience a breakage resulting in maximum brand reputation damage.

The peak force is captured by the gauge for ultimate break strength comparison.

Barry M aims to let its customer choose a lipstick for the look and to be confident it will perform; ground-breaking without breaking—or shearing, fracturing or crumbling.

MultiTest-dVMotorised force tester

Product Tester
MultiTest-dV with AFG

The MultiTest-dV range integrates perfectly with our Advanced Force Gauge, making it a popular configuration for standalone applications that require the capture of a peak load value.

Expand its capabilities by connecting to VectorPro Lite software for presenting data graphically and performing calculations to see test results.

Materials Tester
MultiTest-dV with ELS

The MultiTest-dV range configured with an Enhanced Load Sensor, VectorPro MT software and an optional extensometer, transforms this motorised force tester into a basic materials tester.

This makes the MultiTest-dV the ideal choice for quality assurance checks in the QC lab and gives it the power necessary for more in-depth analysis of material properties in the R&D laboratory.

The MultiTest-dV is a versatile and easy to use stand-alone force tester.

Ideal for routine quality control in a production or laboratory environment, with three models rated to 0.5 kN, 1 kN and 2.5 kN.

A motorised test stand can be configured with a Digital Force Gauge for product testing or an Enhanced Load Sensor for basic materials testing.
