FAQs:
Q1: How is the solubility of your products?
A: Our micronization process improves the solubility of our product in simulated gastric juice by over 30% compared to ordinary raw materials. We can provide solubility equilibrium data under different solvents according to your process requirements.
Q2: What if my customs environment is very strict? Do you offer any guarantees?
A: We have our own global logistics system. For sensitive regions such as the US, EU, and Brazil, we use non-sensitive product labels and distributed shipping methods. If customs clearance is impossible due to our packaging issues, we promise to resend once free of charge.
