Topically, peach is used to treat minor skin disorders such as burns, abrasions, blisters, scratches, eczema, psoriasis, and warts.
  • PreparationBy the action of sulfuric acid on undecylenic acid; also prepared starting form castor oil; from octanol-1 plus methylacrylate with di-ter-butylperoxide; from heptylethylene oxide and sodiomalonic ester.
  • Aroma threshold valuesDetection: 60 ppb
  • Taste threshold valuesTaste characteristics at 30 ppm: fatty, coconut, creamy, vanilla, nutty, macadamia and peach.
