Packaging requirements

Packaging materials: Propylene glycol should be packaged with materials that comply with national standards, such as plastic drums and stainless steel containers. The packaging materials should have good corrosion resistance and sealing performance to prevent the leakage and contamination of propylene glycol.
Packaging capacity: The packaging capacity should be determined based on transportation requirements and safety standards. A smaller packaging capacity can reduce the risk of leakage and contamination, and also facilitate handling and loading/unloading.

Functions and Effects

Propylene glycol is a chemical raw material and also an organic compound, with functions such as moisturizing, nourishing and antiseptic.
Propylene glycol is a colorless, odorless and transparent liquid. It is a chemical raw material and also an organic compound. It can be used in the production of cosmetics, skin care products, medicines and other items, and can also be used in thermos cups. Propylene glycol can also be used as a preservative. It can inhibit bacterial growth and improve the moisture retention of products, preventing them from decomposing into water and carbon dioxide

Storing chemical materials safely requires careful planning and adherence to established safety guidelines. 

Understand the Chemical's Properties

Check the Safety Data Sheet (SDS): This document provides critical information on storage, hazards, and handling.

Know if the material is:

Flammable

Corrosive

Reactive

Toxic

Oxidizing

Hygroscopic (absorbs moisture from air)

Use Proper Containers

Use containers that are compatible with the chemical.

Ensure they are labeled clearly with:

Chemical name

Hazard symbols

Date received/opened

Use sealed containers to prevent leaks, evaporation, or contamination.

Storage Environment

Store in a well-ventilated, cool, and dry area.

Avoid exposure to direct sunlight or heat.

Control humidity and temperature as per SDS recommendations.

Segregate Incompatible Chemicals

Keep incompatible groups apart:

Acids vs. Bases

Oxidizers vs. Flammables

Water-reactives away from moisture

Peroxides isolated in tight containers

Use secondary containment trays or cabinets to prevent cross-contamination.
