Rosehip oil is increasingly popular in cosmetics industry due to its extraordinary benefits as a natural beauty product. It contains a lot of essential nutrients, including vitamins, essential fatty acids, therapeutic ingredients and more. Because of its clarifying and rejuvenating beauty effects, rosehip oil has amazingly magical natural healing and beauty functions.
There are many methods to extract rosehip oil, including Cold Pressing, Chemical Extraction, Supercritical Extraction and Sub-critical Solvent Extraction. The quality of rosehip oil is largely decided by its processing procedure, so choose the right method procedure is a key step for rosehip oil extraction.
Analyzing of Different Rosehip Oil Extraction Procedures
| Extraction Procedure |
Advantages |
Disadvantages |
| Cold Pressing |
- Simple oil extraction process;
- Low investment for equipment;
|
- High residual oil ratio in in oil cake/meal;
- High energy consumption;
- The natural active component within the original material will be destroyed by frictions and heating;
|
|
Chemical Extraction
(Haxane)
|
- Higher oil yield than mechanical pressing;
|
- Large solvent residue;
- Has a certain degree of polluting;
- Complicate processing procedures;
- The natural active component within the original material will be destroyed by high processing temperature;
|
| Supercritical Extraction |
- No solvent residues
- High quality oil
|
- Suitable for small scale oil extraction
- Highest investment and strict requirements for extraction machines
|
|
Subcritical Solvent Extraction
(Butane & Propane)
|
- High quality final oil and low residual oil ratio
- Low investment and simple extraction procedures;
- Wide application and suitable for small and large scale oil production;
|
- Newly developed technology (invented by Dr. Qi Kun in 1991, China);
- Compare to traditional press machine and solvent extractoin, its investment is a little higher

The best procedure for extracting rosehip oil is the one that can be carried out to preserve its active components and reveal a golden amber amber color and slight fragrance. And, our sub-critical solvent extraction procedure has been proven to keep all the valuable contents of the oil intact. This advanced extraction technology produces rosehip oil of the highest quality.
