What is the Gel in Ice Packs?

In pharmaceutical cold chain logistics, gel ice packs play a crucial role. Here’s a detailed overview:

1. What is a Gel Ice Pack?

A gel ice pack is an ice pack filled with a special gel material primarily used for temperature control during refrigeration, frozen transport, and storage. These packs can freeze and maintain low temperatures for extended periods, ensuring the proper temperature is maintained during transportation and storage.

2. What is the Gel Component in the Ice Pack?

The gel in ice packs typically consists of the following components:

• Water: The main component, providing basic cooling functionality.
• Polymer Polymers: Such as sodium polyacrylate, which have excellent water absorption and retention properties, forming a gel-like substance.
• Preservatives: Like ethylene glycol, to prevent the gel from deteriorating during long-term use.
• Thickener: Such as sodium carboxymethylcellulose, to increase the gel’s viscosity and stability.

3. Characteristics and Risks of Different Types of Gel Ice Packs

Gel ice packs are available in various types, each with unique characteristics and potential hazards:

• Ordinary Gel Ice Pack:
