How is bisabolol obtained?

Whether derived from plants, synthesized, or produced through biotechnology, bisabolol is a molecule with a thousand benefits. This gentle active ingredient is particularly favored by sensitive and weakened skin. Discover the various methods of obtaining bisabolol used in cosmetics and their respective advantages and disadvantages.

What is bisabolol?

Bisabolol, also known as levomenol, is a monocyclic sesquiterpene alcohol found in certain essential oils. It is particularly present in wild chamomile and candeia. The bisabolol is a very commonly used active ingredient in cosmetics due to its numerous benefits for the skin, the scalp and hair. It is suitable for all skin types and is particularly well-suited for sensitive, irritated, or dry skin.

As anhumectant, bisabolol works by retaining the water present in the skin and reducing insensible losses, which helps to maintain the skin barrier. In addition, it has antioxidant properties that allow it to protect the skin against oxidative stress. Finally, several studies have highlighted the healing and soothing effects of this ingredient, as well as its anti-inflammatory and antibacterial properties.

Vegetable Bisabolol: Its Extraction Process.

The bisabolol found in cosmetic products is often ofplant origin. Here is its extraction process when it comes from the candeia plant. Its method of obtaining from wild chamomile is substantially the same.

  1. Harvesting and Preparation of Candeia Bark : Candeia trees, primarily grown in Brazil, reach sufficient maturity for root harvesting around the age of ten. These roots are harvested in a way that preserves the trees and the surrounding ecosystem. The candeia bark is then cleaned and dried to remove moisture. After which, it is reduced to small particles using grinders or mills. This facilitates the subsequent extraction of the desired compounds.

  2. Steam Distillation : The branches are placed in a still where steam is introduced. The steam passes through the branches and carries away the volatile compounds, including the essential oil, found in the plant tissues. It is then cooled, which allows the water to condense and separate the essential oil. The candéia oil, being less dense, forms the upper phase.

  3. Crystallization and Purification : To extract bisabolol from the essential oil, a crystallization process is carried out. The solution is cooled to form bisabolol crystals, which are then purified through filtration and successive washings, to remove any remaining traces of the essential oil.

  4. Drying : once purified, the bisabolol is dried using a desiccator, creating a partial vacuum, to eliminate any residual moisture.

This process of obtaining bisabolol results in an active ingredient pure enough to be subsequently incorporated into cosmetic products and has the advantage of being environmentally friendly. However, it is relatively expensive. The bisabolol used in Typology skincare products is extracted using this method.

Synthetic Bisabolol: Its Extraction Process.

It is also possible to obtain bisabolol through laboratory synthesis, following several successive chemical reactions.

  1. Preparation of Precursors : The precursors used for the synthesis of bisabolol are generally petrochemical compounds. These precursors are purified before they are made to react with each other.

  2. Diels-Alder Reaction : The key reaction for the synthesis of bisabolol is the Diels-Alder reaction, which involves the cyclo-addition of a diene, a compound with two double bonds, with an alkene, a molecule having a double bond. This allows for the production of a compound referred to as a bisabolol precursor.

  3. Hydrogenation : The cyclic precursor obtained from the Diels-Alder reaction undergoes a hydrogenation step, where double bonds are reduced to single bonds. This leads to the formation of bisabolol alcohol.

  4. Purification and Refinement : The synthesized bisabolol is then subjected to stages of purification and refinement to remove impurities and obtain a pure form of bisabolol.

This chemical synthesis typically allows for the production of a more pure form of bisabolol than plant extraction. However, it is more polluting.

Bisabolol derived from biotechnology: how is it obtained?

Still under development, the third method of obtaining bisabolol involves advanced biotechnologies. It is done by bacterial fermentation, meaning that it is bacteria, often of the Escherichia coli type, that produce the bisabolol. Here are the main steps followed:

  1. Bacterial Strain Selection : A strain of bacteria, often E. coli, is selected for its ability to express α-synthase, the gene responsible for the synthesis of bisabolol. This gene can notably be obtained from the German chamomile flower.

  2. Construction of the Expression Vector : The α-synthase is inserted into an expression vector, which is then introduced into the cells ofE. coli. This vector allows the bacterial cells to produce the necessary enzymes for the conversion of metabolic precursors into bisabolol.

  3. Cell Culture and Fermentation : The E. coli cells containing the expression vector are grown in a suitable culture medium. The culture conditions, such as temperature, pH, and medium composition, are optimized to promote the production of bisabolol. Fermentation typically lasts several days.

  4. Bisabolol Extraction : Once the fermentation process is completed, bacterial cells are harvested and bisabolol is extracted from the culture medium. Various extraction methods can be employed, such as solvent extraction or distillation extraction.

  5. Purification : The extracted bisabolol is then subjected to purification stages to remove impurities and obtain a purer form of the compound. Purification may involve techniques such as chromatography or crystallization.

This method of obtaining bisabolol allows for reducing production costs and is environmentally friendly. However, it requires advanced knowledge in genetic engineering and specialized facilities.
