Cylinder / Needle Probes For Hardness Measurement

Lipstick Hardness is an important determination and is described in the ASTM Standard Method of Test D1321-95 which specifies the use of a needle penetration test. Besides determining lipstick Hardness , this test may also indicate the presence of unwanted trapped air bubbles, or a "grainy" texture as a result of either incomplete colorant dispersion or the working and chilling processes during manufacture.
