This is a penetration test that measures sample hardness. In the standard method, a penetrometer determines the distance of penetration when applying a specified force over a period of 5 seconds. The method described here is an alternative method .
Lipsticks were stored at room temperature for 24 hours before testing. A CTX texture analyzer with a 1.5 kg load cell was used with a TA-LC apparatus to perform a bend test. This test bends the lipstick a set distance and measures the force required to bend the lipstick. This folding test measures the firmness of the lipstick. Acceptable solid lipsticks for the consumers should achieve at least 30 g-force (gf) at 20 °C for 8.1 and 12.7 mm diameter stick, as reported for current patented lipsticks [30,31,32]. Consequently, hardness values of all lipsticks were considered acceptable since values were above those of the commercial formulation or above 30 gf at 25 °C. Hardness testing can be applied to various types of materials, some of which are listed below: Metals and alloys. Ceramics. Elastomers. Polymers and plastics. Films. Rocks and minerals.
