Gamma Dodecalactone opens with the unmistakable richness of C12 lactones—imagine ripe peaches drowning in heavy cream and melted butter. This isn't the light, ethereal fruitiness of smaller lactones; it's fruit with gravitas, substance, and an almost edible quality. The initial burst reveals overripe stone fruits—peach and apricot—but with a pronounced fatty character that suggests the richness of coconut cream or cultured butter. Metallic undertones add complexity, while an oily quality creates mouth-coating persistence that smaller lactones can't achieve.
Use Gamma Dodecalactone at 0.5-3% when you need fruity notes with exceptional depth and tenacity. Its heavier molecular weight (C12 versus C10 in Gamma Decalactone) transforms the character from creamy-fresh to fatty-rich. Where Gamma Decalactone provides bright apricot-peach with lactonic creaminess, Gamma Dodecalactone delivers a more opulent, buttery interpretation with superior fixative properties. Use it in gourmand accords where you want fruit notes that won't disappear—think peach cobbler rather than fresh peach. In tropical compositions, it bridges fruit and coconut beautifully. Combine with lighter lactones to create dimensional fruit effects spanning from fresh to preserved.
The Difference A Do- Makes
The progression from Gamma Decalactone (C10) to Gamma Dodecalactone (C12) illustrates how two additional carbons dramatically alter olfactory character. Gamma Decalactone offers creamy peach-apricot with fresh, slightly green nuances and moderate tenacity; Gamma Dodecalactone provides fatty, buttery peach with metallic-oily depth and exceptional persistence. The C10 reads as "fresh fruit with cream"; the C12 as "fruit preserved in butter." This isn't simply about intensity—it's about quality transformation. Gamma Dodecalactone's lower volatility means it functions as both a heart and base note, while Gamma Decalactone primarily serves as a top-to-heart material. Choose Gamma Decalactone for bright, fresh peachy effects in colognes and fresh florals; select Gamma Dodecalactone for rich, persistent fruity depth in gourmands, orientals, and anywhere you need fruit notes that last.

General Information
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.
