How mold release lubricants help a cast bullet leave its cavity and what their residue does afterward — migration into surface haze and interference with cup/base grip. The program records the lipstick tube family's 28 catalog models, mechanism diameters Ø12.1 mm and Ø12.7 mm, recorded…

A cushion formula leans on volatile solvents — isododecane among them — for its airy feel, and the compact's job is to keep them in. No evaporation-rate or compression-set value is published; weight-loss verification is a project protocol, anchored by the 16-model compact family, its…

How friction-pin interference and multi-pan lid mass govern hinge torque retention over the life of a palette. The program records the compact family's 16 catalog models, pan capacities 1.7 ml to 20 ml, a nine-pan 0.9 ml layout, and torque and drop testing; no multi-chamber…

A flocked applicator is an adhesive system wearing a fiber coat: the fibers stay where the adhesive holds them, and the adhesive stays where its chemistry holds up against the formula it touches. Flocking is not a recorded decoration capability, and no liquid-eyeshadow packaging model…

A magnetic compact is really two opening systems in one case: the magnet that snaps the lid home and the hinge that controls how that snap feels. The subject this month is the hinge's damping — the resistances that smooth the lid into a deliberate,…

A high-coverage foundation that stops delivering mid-bottle usually fails at the wet end of the pump: residual formula dries on the nozzle tip, film formers skin over exposed surfaces, and the elastomeric check element must reseal cleanly between strokes. This article anchors that problem in…
