Follow the instructions for use: When using 1,3-propanediol-related products, be sure to follow the product instructions and relevant regulations to avoid overdose.

Pay attention to sensitive people: For people with sensitive skin or a history of allergies, products containing 1,3-propanediol should be avoided, especially in skin care products.

Choose trustworthy products: When purchasing food, cosmetics or medicines containing 1,3-propanediol, make sure they are from reputable manufacturers and check the ingredients and usage concentration of the product.

Maintain appropriate contact time and dosage: Avoid long-term exposure to high concentrations of 1,3-propanediol, especially in industrial production environments. Wearing proper protective equipment can reduce potential health risks.


Conclusion

Overall, propanediol is a widely used and relatively safe chemical that plays an important role in food, cosmetics, pharmaceuticals and industrial products. For most people, 1,3-propanediol is safe at compliant concentrations and can provide stability, moisturizing and a good use experience for products.
