A product of advanced aroma chemistry, Veloutone is part of the larger family of jasmolactones and shares some of the radiant, diffusive qualities of its relatives, though with a gentler, velvety profile. Olfactorily, Veloutone strikes a delicate balance between transparency and warmth. Its floral facet is reminiscent of jasmine petals, but it’s far softer and less indolic, with a creamy lactonic quality that feels smooth and enveloping. This is paired with a slightly woody base and a hint of fruitiness that leans toward ripe peach or apricot, lending a natural, skin-like sensuality to compositions. In blends, Veloutone excels as a modifier and enhancer. It has a unique ability to add texture and body without overwhelming a composition, acting almost like a soft-focus lens. Its creamy, floral-woody profile pairs beautifully with white florals like jasmine and orange blossom, while its fruity nuance enhances gourmand accords or freshens green compositions. It’s also a natural partner for woody and musky bases, helping to create a cohesive, smooth dry-down. One of Veloutone’s most valuable attributes is its versatility. It bridges the gap between florals and woods, making it ideal for modern feminine, unisex, or even soft masculine fragrances. It’s often used in creating the "cashmere-like" effect associated with cozy, skin-hugging perfumes, providing a quiet but impactful presence that amplifies a fragrance’s wearability. From a technical perspective, Veloutone is relatively subtle in its intensity but has excellent tenacity. It shines in the heart and base of a composition, where it adds an understated elegance and helps to round out sharper, more aggressive notes. It also blends well with lactonic materials like peach aldehyde or undecalactone to create creamy-fruity accords, or with materials like Iso E Super and Ambroxan for a radiant, woody effect. ## Analysis: Percentage: 100% | Time | Thoughts | Strength (0-10) | Tenacity (0-10) | | -------- | ----------------------------------------------------------------------------------------------------------------------------------- | --------------- | --------------- | | 1 min | Clean, floral, and creamy with a slight green facet. There’s also a subtle camphorous edge. | 5 | 6 | | 5 min | Still very clean and white floral, with hints of lavender coming through. | 5 | 6 | | 10 min | No significant changes, the white floral and green notes remain dominant, with the lavender continuing to show through. | 5 | 6 | | 30 min | Starting to soften up, with the camphorous and lavender notes becoming more pronounced. | 5 | 6 | | 1 hour | Still strong, maintaining the same profile from earlier with the floral, creamy, and camphorous elements. | 5 | 6 | | 2 hours | The lavender and camphorous notes fade, and it shifts to a stronger white floral, with slight lactonic and waxy qualities emerging. | 5 | 5 | | 4 hours | Faded quite a bit, still detectable on the strip but much more subdued. Now smelling similar to Hedione but less diffusive. | 3 | 3 | | 6 hours | Very faint now, still reminiscent of Hedione but hard to discern. | 2 | 2 | | 12 hours | Almost gone, with only the faintest hint of white floral and Hedione remaining on the strip. | 1 | 1 | | 1 day | Completely gone. | 0 | 0 | ## Final Thoughts Veloutone seems like a fantastic addition to any floral formula, especially when paired with Hedione or other white floral materials. It has the potential to elevate and add complexity to a white floral accord by introducing a delicate mix of green, waxy, and camphorous notes. While it’s potent and should be used sparingly, no more than 1-2%, its presence can really enhance the overall composition, adding depth without overwhelming the other florals. Interestingly, this experiment has also helped me realize that I originally misclassified it under Lactones; after further analysis, it's clear that Veloutone is much more aligned with the white floral family. ![[IMG_3858.gif]]
