What stability test is recommended for eye cream (heat, freeze-thaw, shelf life) for U.S. sales?

Quick Answer (for busy buyers)

Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.

• For an eye cream sold in the U.S. (including Amazon), we usually propose a stability package that covers: accelerated heat (e.g., 40C with humidity where applicable), freeze-thaw cycling (multiple cycles to stress emulsions), and real-time shelf-life at ambient conditions.
• We also include packaging compatibility (formula vs. tube/bottle/closure) to reduce risks like separation, discoloration, odor change, leakage, or viscosity drift.
• We can support documentation and testing coordination (e.g., stability protocol, COA for raw materials/bulk, micro-related checks, and third-party reports).
• We do not guarantee regulatory approval, but we can help prepare the files and arrange send-out testing and report tracking as needed.
• Operationally, our MOQ is typically 1000-3000 pcs (simple items may start at 1000; more complex sets often 3000).
• After formula and sample confirmation, bulk lead time is usually 10-20 working days; packaging ordering is often 10-30 working days.
• Common eye-cream packaging lead times: unit carton about 15 days; glass bottle 15 days; acrylic bottle 30 days; tube 15 days.
• Full turnkey brand landing is generally 45-60 days depending on design and testing cadence.
