| Light lotion or body milk | 100–1,000 cP | Standard plastic bottle with a stable shoulder and narrow-to-medium opening | Disc-top cap, flip-top cap, or low-output lotion pump | 0.5–1.5 mL | Body moisturizers, hand lotions, after-sun products | Choose a closure that limits leakage during transport. A smaller opening can improve control for thin formulas. |
| Medium-viscosity lotion | 1,000–5,000 cP | Rigid bottle with a broad shoulder and sufficient internal clearance | Lotion pump or medium-orifice flip-top cap | 1.0–2.0 mL | Daily facial moisturizers, body lotions, family-care products | Confirm that the formula flows consistently after storage. The bottle should support easy evacuation without excessive squeezing. |
| Rich lotion or cream-lotion | 5,000–15,000 cP | Wide-shoulder bottle or inverted squeeze bottle | High-output lotion pump, wide-orifice cap, or squeeze dispensing system | 1.5–3.0 mL | Rich body creams, intensive hand care, cold-weather moisturizers | Use a larger flow path to reduce clogging and improve priming. Inverted designs can help the product move toward the closure. |
| Very thick cream | 15,000–50,000 cP | Wide-mouth jar, wide-neck bottle, or soft squeeze pack | Wide-mouth access, large-orifice cap, or specialized high-viscosity pump | 2.0–5.0 mL | Barrier creams, intensive foot creams, concentrated treatment products | Test product recovery, air exposure, and user handling. A narrow neck may make the pack difficult to empty. |
| Formula with suspended particles | Varies; measure under actual conditions | Bottle with a wide, unobstructed product pathway | Large-orifice pump or cap designed for particulate formulas | 1.0–3.0 mL | Exfoliating lotions, mineral-containing body products, scrub lotions | Check particle size, sedimentation, valve clearance, and repeated-actuation performance to reduce blockage risk. |
| Air-sensitive or oxidation-sensitive lotion | Usually 500–15,000 cP | Opaque or low-light-transmission bottle with a protected dispensing system | Airless pump or low-backflow pump | 0.2–1.5 mL | Active skincare, antioxidant lotions, formulas with sensitive botanical ingredients | Evaluate oxygen exposure, light transmission, compatibility, and priming. Packaging performance depends on the complete formula-pack system. |
| Travel-size lotion | 100–10,000 cP | Compact bottle with reinforced closure and leak-resistant fit | Flip-top cap, screw cap, or compact pump | 0.5–2.0 mL | Trial sizes, hotel amenities, gym kits, travel retail | Prioritize impact resistance, closure security, label space, and compliance with applicable carry-on or transport requirements. |
| Large household or family-use lotion | 500–10,000 cP | Large-volume bottle with a broad base and ergonomic grip area | Lockable lotion pump or controlled-flow flip-top cap | 1.5–3.0 mL | Family body lotion, workplace hand lotion, bathroom dispensers | Consider one-handed operation, drop resistance, pump lockability, refill frequency, and stability when the bottle is nearly empty. |
