Ice
Rigid, melts into a wet mess, doesn't conform to the skin.
The ice pack that stays soft when frozen.
Ice is too hard. Gel packs freeze solid. Eaureco stays flexible like silicone — conforming to the curves of the face, ankle, or joint — and it's grown from natural seaweed, not petroleum.

Is your current cold pack actually comfortable for patients?
Traditional options create pressure, gaps, and inconsistent relief when patients need comfort most.
SAP Gel Packs
Freeze rock-hard, won't fit facial or ankle contours.
After a procedure, patients need cooling that hugs the skin and lasts.
A cold pack that starts by cleaning the ocean.
Sargassum is an invasive seaweed that smothers coastlines and chokes marine life. We harvest it, extract a natural seaweed-derived material, and turn a coastal problem into a clinic-ready cooling material — no petroleum-based gels required.
Recover
Invasive Sargassum is collected before it washes ashore and rots into ocean waste.
Refine
We extract alginate, a natural seaweed-derived polymer, using a water-based process.
Reimagine
It becomes a soft, long-lasting cold-pack gel for clinics and patients.

Three Advantages.
One better cold pack.
Flexible Conformity
Stays soft and pliable even when frozen. Conforms seamlessly to the curves of the face, ankle, or joint for even cooling.
Long-Lasting Cold
Stays cold through a full cooling session, so packs are swapped out less often.
Quick Turnaround
Refreezes in a standard clinic freezer, so packs cycle back into use on busy days.
Use Cases
Designed to conform where rigid cold packs cannot.
Plastic Surgery / Dermatology
Post-op facial cooling, post-laser cooling. Soft conformity to facial contours.
Dental
Post-extraction, post-implant, wisdom tooth surgery. Wraps naturally around the jawline and cheek.
Orthopedics
Ankle sprains, post-op swelling, everyday recovery. Conforms to ankles, knees, and wrists.

PatentKorean patent filed (January 2026)
Eaureco cold packs are general consumer goods, not a licensed medical device. They are not intended to diagnose, treat, cure, or prevent any disease. Please follow your clinician's guidance on post-procedure cooling.
Turning the ocean's burden into everyday materials
Every year large volumes of sargassum wash ashore from Jeju to Florida and Puerto Rico, cleared away at significant public cost. Over the same period, single-use petroleum-based ice packs and gels are thrown away at scale. Eaureco turns this discarded ocean resource into a seaweed-derived gel that replaces the petroleum-based SAP inside the pack.
Cold that performs, without petroleum SAP.
Born from ocean waste
Biodegradable seaweed-derived gel inside; the pouch is plastic and is not biodegradable
Beyond cold packs: cold chain and hygiene materials
A materials startup founded by a KAIST researcher.
Eaureco develops a new class of cold-pack materials from a seaweed-derived material extracted from Sargassum — an invasive seaweed that damages coastlines worldwide. By engineering with nature instead of against it, we replace petroleum-based gels with a soft material that keeps post-procedure cooling comfortable.
Science-led
Built on our own seaweed-derived gel process, filed as a Korean patent application in January 2026.
Ocean-positive
Every pack starts by removing invasive seaweed from coastlines.
Patient-first
Soft conformity and cold that lasts, for comfort after a procedure.
