Are there solvent residues in the osmanthus flower wax? Is it safe?
Although solvent extraction is used, the solvent is removed under vacuum after extraction, and residual levels are strictly controlled and tested on every batch.
Safety Control Measures
- Vacuum removal — solvent is evaporated under reduced pressure after extraction
- Batch testing — residual solvent is analyzed by GC and reported on the COA
- Compliant limits — residues meet the limits for cosmetic and fragrance raw materials
- Food/cosmetic grade options — available for stricter applications such as personal care
Our process is designed so that the final wax meets the safety expectations of the EU Cosmetic Regulation (EC 1223/2009) and common IFRA guidelines for botanical raw materials.
Share your target residual solvent specification, and we will confirm compliance with the COA of your batch.
