Storing Sorbitol? Start Here

Sorbitol 70% solution is a key ingredient in many personal-care and pharmaceutical products, acting as a humectant, sweetener, and bulking agent. It's commonly used in toothpaste, mouthwash, and cosmetics. When storing sorbitol, it's important to maintain the right conditions to prevent crystallization, especially in cooler climates. This solution is typically stored in HDPE tanks with heat tracing to keep it at a stable temperature.

Can you store it in a poly tank?

Yes, sorbitol 70% solution can be stored in HDPE or XLPE rotomolded tanks. These materials are standard for cosmetic and pharmaceutical applications, provided the tanks are kept warm to prevent crystallization.

Watch out for crystallization

Sorbitol 70% solution can crystallize if the temperature drops below 15°C. To avoid this, tanks should be equipped with insulation and electric heat tracing, maintaining a temperature between 25-40°C.

The safety that actually matters

• Ensure tanks are made from FDA-approved food-contact materials.
• Maintain proper temperature to prevent crystallization.
• Follow GMP cleaning and sanitization practices to prevent microbial growth.
