AMETEK Sensors, Test & Calibration Offers Range of Lipstick Testing Kits

HORSHAM, PA – The measurement of texture and the mechanical strengths of lipsticks are key manufacturing parameters for lipstick manufacturers. AMETEK Sensors, Tests & Calibration (STC), manufacturer of Chatillon and Lloyd Instruments test equipment, offers a range of lipstick testing kits for testing break-strength, firmness and rupture as well as slicing, shear and flexure of the lipstick grape.

For decades, leading cosmetics manufacturers in France have used Lloyd Instruments test equipment for testing lipsticks, as well as lipstick packaging. The most popular of which is the LS1 materials testing machine, equipped with a special fork-type fixture for lipstick break-strength testing.

The fork-type fixture was developed by AMETEK STC in co-operation with the French cosmetics houses. It consists of two parts and will accommodate lipsticks up to 20 mm in diameter. The lower part of the fixture provides a gripping mechanism to hold the base of the lipstick during the test, while the upper fixture, shaped like an inverted Y, attaches directly to the loadcell.

When applying a force directly to the lipstick using this fixture, a bending action equivalent to that experienced by the product when in use is simulated, measuring the break-strength of the lipstick. The fixture has a maximum capacity of 50 N.

AMETEK STC also developed an upper fixture with a fine wire attached. It is ideal for slicing the lipstick grape to achieve accurate rupture test results. AMETEK STC’s range of specially engineered lipstick testing kits are available, including a V-type fixture for shear and rupture testing.

Tests performed on the LS1 test machine can be fully automated with NEXYGENPlus software that offers high-precision analysis, a complete library of test setups adherent to international standards, and easy export of data directly to Excel® or Word® templates.

Among the most common tests performed by Lloyd Instruments’ LS1 test machine are spreadability, stickiness, extrudability, compaction strength, compression strength, peel strength and actuation force of pumps and sprays.

Lloyd Instruments is a brand of AMETEK STC, which offers a comprehensive range of materials testing equipment for cosmetics, foods, packaging, plastic, rubber and many other materials.
