Cashew phenol (CAS 37330-39-5), as a renewable bio-based phenol, with its unique structure of rigid benzene ring and flexible long chain, is irreplaceable in high-end materials (resins, coatings), green surfactants and biomedicine fields:
Performance advantages: High-temperature resistance, hydrophobicity, self-drying, superior to petroleum-based phenol;
Environmental protection value: The raw materials are renewable and have a fast degradation rate.
Application potential: The wound healing function in the medical field awaits in-depth development.
1. Resin and Coatings Industry (Core Applications)
Epoxy resin curing agent: Replace 30% phenol, enhance toughness, water resistance and electrical insulation.
Phenolic resin modification: used in high-temperature resistant friction materials such as rocket components and high-speed rail brake pads.
Coating additives: Enhance anti-corrosion and self-drying properties, suitable for Marine and industrial protective paints.
2. Surfactants
Cashew phenol polyoxyethylene ether: It can replace nonylphenol and is used as a crude oil demulsifier and low-foaming cleaner. It is biodegradable quickly and has low skin irritation.
3. Biological activity and pharmaceutical potential
Promoting wound healing: A concentration of 1 μg/mL can accelerate the migration of human keratinocytes (HaCaT), with a closure rate of up to 99%.
Regulating fatty acids: Increase polyunsaturated fatty acids such as ω-3/6/9 (PUFA), which have antioxidant potential.
4. Other fields
Rubber/plastic: Antioxidant, enhancing heat resistance and mechanical strength.
Ink/Adhesive: Pigment dispersant, improving printability.
Health risk:
High concentration (>10 μg/mL) can cause DNA damage (comet experiment);
Irritating to the skin/eyes (Protective equipment should be worn during operation).
Environmental friendliness: Its biodegradability is superior to that of petroleum-based phenols, in line with the trend of green chemical engineering.
Regulation: China's "Cashew Phenol Industry Standard" (implemented in June 2025) regulates quality indicators.
