FAQ

Q: How to choose between DPG and propylene glycol (PG)?

A: DPG has stronger moisturizing properties and evaporates more slowly, but the cost is higher; PG is more suitable for products that need to evaporate quickly.
Q: Will it cause skin irritation?

A: The sensitization is lower than PG (rabbit skin test PII=0.3), but the recommended dosage for sensitive skin is ≤5%.
Q: Can it be used for e-cigarette oil?

A: It can be used as an alternative solvent for VG/PG, but the atomization stability needs to be verified.
