How pore-blurring primers work: silica and PMSQ powders scatter light, silicone elastomers fill texture, and absorbent powders hold the matte finish all day.
Compare silicone vs water-based primer bases for private label makeup: cost drivers, filling, stability data, skin-type fit. Get GMPC and ISO 22716 formulas.
Face primer texture stability problems: syneresis, gelling, phase separation, pilling. Know which stability data to request from an OEM factory pre-launch.
Mono-material packaging means one resin across every part of a cosmetic package. See where single-resin lipstick and gloss designs work, and what to check before tooling.
PCR plastic in cosmetic packaging cuts virgin resin use but risks color shift, odor, and brittle hinges. Learn how to specify tiers, tolerances, and testing.
