How to Store Glycolic Acid Safely and Effectively
A common alpha-hydroxy acid (AHA), glycolic acid is well-known for its efficacy in chemical peels, skincare products, and other industrial uses. To preserve its strength, stability, and safety, glycolic acid must be stored properly. Chemical deterioration, loss of efficacy, and even safety risks like skin irritation or unintended chemical reactions can result from improper storage. The solution to storing glycolic acid is to adhere to stringent safety procedures, material compatibility, and storage conditions.
Prior to shipping, Lab Alley ensures that every glycolic acid product is properly packaged, labeled, and stored. Following the same safety precautions after delivery is equally crucial for maintaining a safe working environment and protecting product quality.
In this article, we’ll explain:
1. Recommended Storage Conditions
2. Storage Containers & Packaging
3. Segregation & Chemical Compatibility
4. Safe Handling in Storage Areas
5. Regulatory Compliance & Labeling
Recommended Storage Conditions For Glycolic Acid
Glycolic acid needs to be stored in a controlled environment to maintain its integrity. By taking these precautions, the acid is kept stable and degradation is lessened:
- Temperature: Store glycolic acid at room temperature, ideally between 15–25°C (59–77°F). Avoid extreme temperatures, including both heat and freezing conditions, as these can destabilize the solution.
- Humidity Control: Always keep containers tightly sealed. Exposure to moisture can dilute the acid and reduce its effectiveness.
- Light Exposure: Glycolic acid should be stored in opaque or amber-colored containers to protect it from UV light, which can cause chemical breakdown over time.
- Ventilation: Store in a well-ventilated area and away from reactive chemicals such as strong bases and oxidizers.
Storage Containers & Packaging
The type of storage container you use also impacts glycolic acid’s shelf life and safety:
- Use corrosion-resistant containers, such as high-density polyethylene (HDPE) or glass, to prevent chemical reactions with the container.
- Make sure all containers are tightly sealed with screw caps or chemical-resistant lids to prevent evaporation, contamination, or air exposure.
- Label containers clearly with hazard symbols, concentration, expiration dates, and safety warnings in compliance with GHS (Globally Harmonized System) standards.
Segregation & Chemical Compatibility
Because glycolic acid can react with certain substances, it’s important to store it separately from incompatible materials:
- Incompatible Chemicals: Keep glycolic acid away from strong bases, oxidizers, and reducing agents, which can trigger hazardous reactions.
- Segregated Storage: Use designated acid storage cabinets and store glycolic acid separately from flammable or reactive chemicals.
- While glycolic acid is not highly flammable, it should still be stored away from ignition sources as a safety precaution.
Lab Alley guarantees that all glycolic acid is handled and transported in complete accordance with legal requirements, utilizing suitable containers and packaging to maintain quality. To guarantee long-term stability and safe use, customers should continue to adhere to the correct handling and storage procedures after delivery.
Safe Handling in Storage Areas
Handling concentrated glycolic acid requires care, even in storage environments:
- Wear proper PPE: Gloves, safety goggles, and lab coats are essential when handling glycolic acid to prevent skin or eye irritation.
- Use safe transfer methods: When pouring or transferring glycolic acid, use chemical-resistant containers or a transfer pump to avoid spills.
- Spill Response: Have spill kits on hand with neutralizing agents such as sodium bicarbonate. Ensure adequate ventilation and follow your facility’s chemical spill procedures.
Regulatory Compliance & Labeling
To stay compliant with safety regulations, follow these guidelines:
- OSHA & GHS: Ensure that all labeling and storage practices comply with OSHA’s hazard communication standards and GHS labeling requirements.
- DOT Regulations: If glycolic acid needs to be transported, follow Department of Transportation (DOT) guidelines for handling and shipping hazardous materials.
- Industry-Specific Standards: Depending on your application, you may also need to comply with EPA, NFPA, or REACH storage and safety protocols.
Whether glycolic acid is used in industrial formulations, lab research, or skincare products, proper storage guarantees long-term stability, efficacy, and regulatory compliance.
You can be sure that your glycolic acid will be safe, dependable, and effective from the time of purchase to the end of its useful life if you adhere to these best practices and work with a reputable supplier like Lab Alley.
