Propylene Glycol Cosmetic + USP Tank Selection

Storing Propylene Glycol Cosmetic? Start Here

Propylene glycol is a versatile ingredient used in cosmetics, lotions, shampoos, and pharmaceuticals. It's a humectant, which means it helps retain moisture, making it a staple in many personal-care products. If you're in the business of manufacturing or storing these products, understanding the best way to store propylene glycol is crucial for maintaining its quality and effectiveness.

Can you store it in a poly tank?

Yes, you can store propylene glycol in a poly tank. High-density polyethylene (HDPE) and cross-linked polyethylene (XLPE) tanks are both suitable options for storing propylene glycol at ambient temperatures. These materials are chemically compatible and commonly used in the cosmetic and pharmaceutical industries.

Key Storage Issue: Moisture Exclusion

Propylene glycol is hygroscopic, meaning it absorbs moisture from the air. This can affect its concentration and performance in formulations. Ensure your storage tanks are sealed properly to prevent moisture ingress. This is especially important in maintaining the quality of cosmetic and pharmaceutical products.

The safety that actually matters

• Ensure tanks are properly sealed to prevent moisture ingress.
• Maintain ambient storage conditions to avoid thermal degradation.
• Follow GMP cleanability and sanitization standards for your industry.
