Keep it tightly sealed, keep away from the sun, avoid contact with air, and store in a cool, dry and ventilated place. Store and transport in accordance with toxic chemicals regulations.
1. Container: Use airtight containers made of compatible materials, such as glass or certain plastics, to prevent contamination and evaporation.
2. Temperature: Store in a cool, dry place away from direct sunlight and heat. Ideally, keep the temperature below 25°C (77°F).
3. Ventilation: Make sure the storage area is well ventilated to avoid vapor accumulation.
4. Incompatibility: Glyoxylic acid should be kept away from strong oxidants, bases and other reactive substances to prevent dangerous reactions.
5. Label: Clearly label containers with chemical name, concentration, and hazard information.
6. Safety Precautions: Use appropriate personal protective equipment (PPE), including gloves and goggles, when handling and storing glyoxylic acid.

This product is a colorless or light yellow liquid. It is miscible with water, slightly soluble in ethanol and ether. Insoluble in esters and aromatic solvents. The solution is extremely stable and does not deteriorate when placed in the air, and glyoxylic acid exists in a hydrated form in the aqueous solution. Corrosive.
When transporting glycolic acid, several precautions must be taken to ensure safety and adhere to regulations. Here are some key considerations to take into account:
1. Packaging: Use containers suitable for glyoxylic acid, such as glass or some plastics. Make sure the container is tightly sealed to prevent leakage and evaporation.
2. Label: Clearly label all containers with the chemical name, hazard symbol and any relevant safety information. This includes indicating that it is a corrosive and potentially hazardous substance.
3. Personal Protective Equipment (PPE): Ensure that personnel involved in transportation wear appropriate PPE, including gloves, goggles, and protective clothing to minimize exposure.
4. Temperature Control: If necessary, transport glyoxylic acid in a temperature-controlled environment to avoid extreme temperatures that may affect its stability.
5. Avoid Mixing: Do not transport glycolic acid together with incompatible substances (such as strong oxidizers or bases) to prevent dangerous reactions.
6. Emergency Procedures: In case of spills or leaks during transport, develop emergency procedures. This includes having spill kits and first aid supplies ready.
7. Regulatory Compliance: Ensure compliance with local, national, and international regulations regarding the transportation of hazardous materials. This may include obtaining necessary permits and adhering to specific shipping guidelines.
8. Training: Ensure that all personnel involved in the transport of glyoxylic acid are trained in the handling of dangerous goods and are aware of the risks associated with glyoxylic acid.
