Bainilan successfully protects patent for rose oil extraction technique

Yunnan Bainilan Biological Resources Development Co. Ltd. has recently secured a patent for an innovative method of extracting essential oil from fresh rose flowers, which marks a significant advancement in the field of rose oil production. This method offers superior efficiency compared to traditional techniques, leading to higher yields of rose oil and reducing the environmental impact associated with the process. The company's method highlights its commitment to sustainable and innovative solutions in the biological resources industry.


Overview of the Extraction Method


The patented method revolves around using organic solvents to extract rose oil from fresh flowers, followed by molecular distillation to refine the product. Key steps in this process include:


1. Initial Solvent Extraction: Fresh roses are soaked in a solvent, such as petroleum ether, which dissolves the essential oils. This process is repeated four times to maximize oil extraction.

2. Filtration and Wax Removal: After extraction, the mixture is filtered and treated with ethanol to remove unwanted wax and other impurities. The liquid is then cooled to solidify and filter out the wax.

3. Secondary Extraction: The leftover flower material is re-soaked in a mixture of solvents to extract any remaining oils. This second extraction is again filtered and concentrated.

4. Molecular Distillation: Both the first and second concentrated extracts are distilled using molecular distillation. This step ensures that any remaining solvents, waxes, and pigments are removed, leaving behind a pure, aromatic rose oil.


The result is a high-quality rose oil that boasts a pure scent and a clear color, with an extraction efficiency three times greater than the traditional steam distillation method. This new approach not only improves yield but also reduces the environmental footprint of rose oil production, as it minimizes waste and optimizes resource use.


Patent and Protection


Bainilan applied for priority patent review on June 10, 2022, to safeguard this technology. The patent covers not only the extraction process but also methods for handling the by-products, such as rose flower residue, which is often discarded or underutilized in traditional methods. By using enzymatic and microbial fermentation techniques, the company is able to transform this waste into valuable raw materials for use in cosmetic and personal care products.


This innovation falls under the "biological manufacturing industry" category in China's strategic emerging industries, which emphasizes clean and sustainable technologies. The company has presented this invention as a solution to the ongoing environmental issues caused by rose flower waste and has outlined its significant benefits in reducing costs and improving sustainability in rose oil production.


Importance for the Industry


This patent is an important milestone for Bainilan, as rose essential oil is highly valued in the cosmetics and perfumery industries due to its unique fragrance and medicinal properties. Often referred to as "liquid gold," rose oil is known for its complex, sweet aroma and therapeutic benefits. However, traditional methods of extraction are inefficient, producing minimal yields and leaving behind significant amounts of waste.


The company's method addresses these challenges by:


Increasing the yield of rose oil to 0.1%, compared to the 0.03% yield typical of steam distillation.

Reducing waste by utilizing rose flower residue, a by-product that was previously discarded or used as fuel, which often leads to environmental pollution.

Lowering production costs through the use of efficient extraction techniques and the recycling of solvents and materials.


By advancing rose oil extraction methods and promoting sustainability, Bainilan is positioning itself as a leader in both the biological and cosmetic industries. This patent not only ensures the company's intellectual property is protected but also paves the way for further innovations in the use of natural resources.
