Cosmetic wand-package testing: temperature and altitude
The work evaluated three anonymized package variants, separating temperature-related formulation and applicator behavior from leakage risk under reduced pressure.
Selected findingAt 40 °C, maximum losses were 93 mg, 52 mg, and 51 mg; the 93 mg result came from one anomalous unit, while the maximum among the remaining Variant A units was 46 mg.
