    Gamma Undecalactone (also incorrectly referred to as Aldehyde C-14 as it is really a lactone and not an aldehyde) is the classic peach note for perfumes. It was discovered in 1908 and was first used as part of the key of the sweet Persicol base in Nuit de Chine (1913) by Maurice Schaller for Paul Poiret's Les Parfums de Rosine, but most famously a few years later as the key peach note (in the same Persicol base) in Mitsouko (1919) by Jacques Guerlain.

    Undecalactone Gamma can be used at 1% dilution to add a luscious and softening effect to a fragrance, and in higher doses (at 10% or pure) for a clearly peach-like quality. Amounts under 1% are most common but there is no limit on this material and doses far higher are perfectly fine.

    Below we present a number of demonstration formulas using Persicol or Undecalactone Gamma. You can simply replace the Persicol with around 80% of the same quantity in Undecalactone Gamma for a perfectly good result.

    General Information

    Like most suppliers and makers of quality raw materials for fragrances, we do not filter many of our products. This ensures that no odiferous matter is lost prior to use but can result in the appearance of small particles or slight clouding.

    All alcoholic fragrances should be macerated for up to a month and then chilled in a moderate freezer overnight before being filtered fine. This will remove all cloudiness or detritus and is the industry norm.

    IFRA Standards

    Permitted amounts in finished product:

    IFRA 51: 100%
    IFRA 49: 100%

    These are derived from calculated concentrations which do not replace chromatographic quantification on individual lots. Disclaimer...
