Citronellal

Natural Citronellal

Natural Citronellal is a natural acyclic monoterpene aldehyde isolated via vacuum precision rectificationfrom Java/Ceylon Citronella Oil (Cymbopogon winterianus/C. nardus), predominantly d-(+)-citronellal. It constitutes 30%–40% of the oil, delivering a strong fresh citrus + citronella + rose aroma with subtle woody undertones. A key ingredient for premium fragrances, natural mosquito repellents, it also offers antimicrobial, sedative & insect-repellent properties, with production centered in Southeast Asia & South China.

2. Source & Production Process
  • Natural Source
  • Features: 100% botanical origin, high natural optical purity, pure aroma, intact bioactivity, FEMA/GRAS compliant, Kosher/Halal eligible.
3. Main Applications
（1）Flavors & Fragrances (Primary Use)
  • Personal care fragrances: Citrus, lime, rose, herbal, cologne, insect-repellent bases/top notes; for perfumes, toilet water, aromatherapy, soaps, detergents, body care (refreshing, odor-masking, luxury enhancement).
  • Food flavors: Citrus, lemon, cherry, berry, spicy profiles; for soft drinks, candies, baked goods, ice creams, chewing gums (bright fruity notes, mild spiciness).
  • Tobacco & industrial: Tobacco flavors (fruity notes, reduce irritation); coatings, rubber, inks (natural fragrancing, antibacterial).
（2）Natural Mosquito/Insect Repellent (High Growth)
  • Repellent activity: Broad-spectrum against mosquitoes, fleas, lice, mites, aphids; superior to some synthetic repellents; natural low toxicity, mild skin irritation.
  • Products: Repellent sprays, toilet water, candles, outdoor mist, pet care, grain storage pest control (eco-safe, long-lasting, gentle).
（3）Fragrance Synthesis Intermediate (High Demand)
  • Key raw material: Hydroxycitronellal (premium fixative), citronellol, menthol (L-menthol), isopulegol, rose oxide; critical precursor in the global menthol supply chain.
  • Pharmaceutical intermediate: Juvenile hormones, antimicrobials, sedatives.
（4）Personal Care & Cosmetics
  • Hair/body care: Body washes, shampoos, soaps, toothpaste, mouthwash (fresh aroma, antibacterial/antipruritic, oil control, odor improvement).
  • Skincare: Toners, serums, lotions (antioxidant, anti-inflammatory, soothing, brightening).
