In hair care products, betulin can help inhibit the degradation of proteins in hair fibers, improve the smoothness and shine of damaged hair, and has potential applications in scalp health maintenance and hair growth promotion. Therefore, it is widely used in repairing shampoos, conditioners, hair masks, and scalp care products. The recommended addition level in cosmetics is generally 1%–2%, and the specific addition ratio can be optimized according to the product formulation.
Beyond the cosmetic industry, birch bark extract, due to its natural source and rich bioactivity, is also receiving widespread attention in functional foods, dietary supplements, and pharmaceutical research and development. Related studies show that it has potential value in many aspects, including antioxidant, immunomodulatory, antibacterial, and supportive of bodily health, providing high-quality plant-based active ingredients for the development of functional products.

How to make White Birch Bark Extract ?
Raw Material Preparation
Before production begins, the purchased birch bark undergoes rigorous raw material acceptance testing, checking for appearance, moisture content, impurities, and other quality indicators to ensure it meets production requirements. Qualified raw materials are cleaned and dried, then pulverized using a grinding device to achieve a suitable particle size. This increases the contact area between the raw material and the extraction solvent, improving the extraction efficiency of subsequent active ingredients.
Ethanol Extraction
The pulverized birch bark is added to 80% ethanol as the extraction solvent and extracted under heating with continuous stirring. Depending on the industrial production scale, various processes such as maceration extraction, reflux extraction, percolation extraction, decoction extraction, or continuous extraction can be used, and multiple extractions can be performed according to process requirements to fully release betulinol and other triterpenoid active ingredients in the bark. After extraction, the extracts are combined, and plant residues are removed through filtration to obtain a clear birch bark extract.
Purification and Crude Betulin Preparation
The filtered extract enters the purification system, where it is adsorbed and eluted using macroporous adsorption resin to effectively remove sugars, pigments, and other polar impurities, increasing the enrichment of the target component. After the eluent is concentrated under reduced pressure to recover ethanol, dichloromethane is added to the precipitated crystals for dissolution, and the pH of the system is controlled at 2.0–2.5. The solution is then allowed to stand and filtered, and repeatedly washed with purified water until neutral to obtain crude betulin extract. The crude extract is purified by sequentially adding dilute acid and bicarbonate aqueous solution, followed by thorough washing with pure water, finally collecting a white powdery insoluble residue.
Recrystallization and Drying
The obtained powdery intermediate is dissolved thoroughly in methanol and recrystallized under controlled process conditions, causing betulin to gradually precipitate into high-purity crystals. The crystals are washed after solid-liquid separation to further remove residual impurities and solvents, and then thoroughly dried using a vacuum drying device to reduce the product's moisture and residual solvent content. After drying, the crystals are crushed and sieved to ensure uniform particle size and good flowability, ultimately yielding birch bark extract powder.
Quality Inspection
After production, each batch undergoes comprehensive quality control testing, including betulinol content (HPLC), product appearance, color, odor, moisture, ash content, particle size, residual solvents, heavy metals, and microorganisms. This ensures the product meets the company's quality standards and customer technical requirements. Only products that pass the tests proceed to the packaging process, guaranteeing stable purity, excellent quality, and good batch consistency for each batch.
Packaging and Storage
The qualified birch bark extract powder is packaged in a clean packaging workshop, typically using food-grade double-layer polyethylene inner bags combined with aluminum foil bags or cardboard drums to effectively prevent moisture, oxidation, and contamination. The packaged product is stored in a cool, dry, and light-protected environment to maintain its stability and active ingredient content. The entire packaging and storage process is managed according to standardized requirements to ensure the product maintains excellent quality during transportation and long-term storage.
White Birch Bark Extract benefits
White Birch Bark Extract for skin
Related studies have shown that birch-derived active ingredients can reduce inflammatory cytokines and improve skin cell stimulation, decrease the expression of inflammatory-related cytokines (such as IL-1β, IL-6, and IL-8), and inhibit the overactivation of inflammatory signaling pathways such as MAPK and NF-κB, thereby helping to alleviate skin discomfort caused by external stimuli and improve skin comfort.
Meanwhile, birch-derived ingredients also demonstrate a supportive effect on skin barrier function, improving skin hydration, reducing transepidermal water loss (TEWL), alleviating irritation-related symptoms such as redness and epidermal thickening, and helping to maintain epidermal barrier integrity and skin health. These research results indicate that birch bark extract, as a natural plant-derived cosmetic ingredient, has significant application value in the development of formulations for soothing and repairing, moisturizing and locking in moisture, barrier maintenance, and sensitive skin care.
White Birch Bark Extract for antibacterial
Studies have shown that birch bark extract possesses strong antibacterial activity against a variety of Gram-positive bacteria associated with skin health. Furthermore, in an in vitro scratch model, birch bark extract also demonstrated a wound-closing effect, exhibiting better wound repair performance than the control group, indicating that it not only helps inhibit the growth of some skin-associated microorganisms but also supports the skin's natural repair process.
Due to the synergistic effect of its antibacterial activity and repair-promoting capacity, birch bark extract has become a promising bioactive ingredient derived from natural plants.

Study On The Hypolipidemic Effect Of Birch Bark Extract
In recent years, the incidence of hyperlipidemia has shown a trend of increasing year by year and becoming younger. It is mainly a disease in which the lipid level in plasma is higher than normal due to abnormal fat metabolism, and it is the main factor leading to atherosclerosis. , can cause serious cardiovascular and cerebrovascular diseases, therefore, the development of safe and effective lipid-lowering drugs has a good prospect.
White birch (Betula platyphylla Suk.) is widely distributed in Northeast my country. It is a plant belonging to the Betaceae Betula family. Jaundice, mastitis and other diseases. Among them, birch triterpenoids have a tumor inhibition rate of more than 30% on each tumor strain, and a tumor inhibition rate of 51.4% on melanoma B16, which is better, and it can also promote macrophages. Cells and spleen cells secrete tumor necrosis factor (TNF), which increases the cytotoxic activity of macrophages. Another study shows that betulinic acid has significant anti-melanoma and anti-HIV activities.
At present, there are no reports on the blood lipid-lowering effect of birch bark extract at home and abroad. This experiment preliminarily studied the blood-lipid-lowering effect of birch bark extract on hyperlipidemia, aiming to provide a basis for the development of birch bark extract as raw material. Provide a theoretical basis for the blood lipid-lowering health products.
