What is Cashew Nut Shell Liquid (CNSL)?
Cashew Nut Shell Liquid (CNSL) is a special industrial oil obtained from the hard shell covering cashew nuts. Although it cannot be used in food like other common oils, cashew nut shell liquid is of great value in many fields thanks to its unique chemical properties. With a high content of useful compounds such as anacardic acid, cardanol and cardol, this oil has become a valuable raw material in industries such as paint, plastic, rubber and chemical production.
Cashew Nut Shell Oil
The main components of cashew nut shell oil include:
Anacardic acid: This is the compound with the highest proportion in cashew nut shell oil, with strong antioxidant and antibacterial properties.
Cardanol: A product converted from anacardic acid, used in the production of paints, plastics, insulators, and anti-corrosion products.
Cardol: Another compound in CNSL, which is corrosive and used in the adhesive and chemical manufacturing industry.

Specific component content
Cashew Nut Shell Liquid (CNSL) contains many unique chemical compounds, with specific contents often including:
Anacardic acid (60-65%):
The main component in CNSL, has antibacterial, antifungal and antioxidant properties. Anacardic acid is widely used in pharmaceutical and cosmetic products due to its anti-inflammatory and cell-protective properties.
Cardanol (20-25%):
A derivative of anacardic acid when heat treated. Cardanol has the property of reducing the brittleness of plastics and increasing their thermal and chemical resistance. It is widely used in the plastics, paint, insulation and rubber industries.
Cardol (10%):
It is corrosive and is often used in special chemical applications, such as the production of waterproofing agents, anti-rust agents and adhesives.
Other minor polymers (about 5%):
A number of other minor compounds exist in CNSL, which play a supporting role for industrial applications.
Oil extracted from the shell of the cashew nut
Cashew nut shell oil can vary in composition depending on the extraction and processing. In industry, it is processed to increase the cardanol content because this compound has a high value in the production of synthetic materials. Anacardic acid also has many potential medical applications due to its antibacterial and antioxidant properties.
Cashew shell oil is commonly used in industries such as:
Plastics and rubber industry: Used to produce synthetic resins and heat-resistant and chemical-resistant rubber.
Paint and varnish production: CNSL is used as a raw material for the production of paints and anti-rust and anti-corrosion products.
Insulation industry: Thanks to its good insulation and heat resistance.

Conclusion:
Cashew shell oil is not only a by-product of cashew processing but also an important industrial resource. With its wide range of applications in various industries, from the production of anti-corrosion materials to the manufacture of synthetic resins and insulators, cashew shell oil has demonstrated its commercial and environmental potential. However, the handling and use of this oil must be done carefully due to its corrosive and toxic properties. This confirms the importance of further research and development of safe and effective exploitation technologies from this source of raw materials.
