Important Information if a Cooling Pack Fails

Please consult your health care professional prior to using UnderCool or any body cooling product for a medical condition. ThermApparel Cooling Packs are designed for the specific objective of cooling the body. ThermApparel LLC will not be liable for injuries or damages resulting from misuse or misapplication of our products.

GHS (Globally Harmonized System) classifies our cooling packs as not a hazardous substance or mixture with no hazardous ingredients. 
 ThermApparel Safety Data Sheet.

Tips for Cleaning

The Phase Change Material is similar to vegetable oil. Any cleaning solution you would use to clean up vegetable oil should work. For clothing, carpet or upholstery, use a cleaner that works on oil or grease stains. Test a small area first with the cleaner, to make sure it won’t cause any damage or discoloration. 

First Aid Measures

If inhaled: If breathed in, move person into fresh air. If symptoms persist, call a physician.

In case of skin contact: In case of contact, immediately flush skin with plenty of water wash with soap and water. Remove contaminated clothing and shoes. If symptoms persist, call a physician.

In case of eye contact: In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

If swallowed: Call a poison control center or doctor immediately.

When using UnderCool's cooling packs, DO NOT: 

  • Do Not put in dishwasher, washing machine, dryer or microwave. (They will explode or us, we've tried and it's messy.)
  • Do Not keep near an open flame, sharp objects or pets.
