Let’s break down these fragrance ingredients:

• 1-(1,2,3,4,5,6,7,8-Octahydro-2,3,8,8-tetramethyl-2-naphthalenyl)ethanone: This is a synthetic fragrance ingredient commonly known as Iso E Super. It has a subtle, woody, amber-like, and musky scent. It’s often described as having a velvety or smooth quality. It’s incredibly versatile and is used as a base note in many perfumes, providing a foundation for other scents to build upon. It’s also known for its “lift” and diffusion properties, helping other fragrance notes to project and last longer.

• Benzyl salicylate (Phenylmethyl-2-hydroxybenzoate): As described previously, this is a naturally occurring ester found in various plants. It has a sweet, floral, and slightly balsamic scent with subtle powdery undertones. It acts as a fixative and contributes a sweet, floral note. It’s also a potential allergen for some individuals.

• Coumarin (1-Benzopyran-2-one): As previously mentioned, Coumarin is a naturally occurring compound found in many plants. It has a sweet, warm, vanilla-like, hay-like, or almond-like scent.

• Geraniol (3,7-Dimethyl-2,6-octadien-1-ol): As previously described, geraniol is a naturally occurring monoterpenoid alcohol with a sweet, rosy, and floral scent.

• Linalool (3,7-Dimethyl-1,6-octadien-3-ol): As described before, Linalool is a naturally occurring monoterpene alcohol with a fresh, floral scent with a slightly sweet and woody undertone.

• Nerol (cis-3,7-Dimethyl-2,6-octadien-1-ol): Nerol is a naturally occurring monoterpenoid alcohol found in plants like neroli (orange blossom) and rose. It has a fresh, sweet, floral, and slightly citrusy scent, often described as having a sweeter and rosier character than its isomer, geraniol.

• Piperonal (3,4-Methylenedioxybenzaldehyde; also known as Heliotropin): This is a synthetic aldehyde with a sweet, powdery, floral scent reminiscent of heliotrope flowers, almonds, or cherry. It’s used to add a warm, powdery, and floral note to perfumes.

• Tetrahydrolinalool (3,7-Dimethyl-3-octanol): This is a synthetic alcohol derived from linalool through hydrogenation. It has a fresh, clean, and slightly floral scent, often described as having a muguet (lily-of-the-valley) or citrus blossom character. It’s used to add a fresh, clean, and floral note to perfumes and other scented products.

• alpha-Hexylcinnamaldehyde (alpha-Hexyl cinnamic aldehyde or HCA) (2-Hexyl-phenyl-2-propenal): As previously described, HCA is a synthetic fragrance ingredient with a sweet, floral scent reminiscent of jasmine. It’s a known potential allergen.

• delta-1-(2,6,6-Trimethyl-3-cyclohexen-1-yl)-2-buten-1-one: This is a synthetic fragrance ingredient often referred to as delta-Damascone. It has a powerful, fruity, floral, and slightly woody scent with aspects of rose, plum, and black currant. It’s used in very small amounts to add a rich, fruity-floral, and often slightly spicy or wine-like note to perfumes.

• dl-Citronellol (3,7-Dimethyl-6-octen-1-ol): As previously described, citronellol is a naturally occurring monoterpenoid alcohol with a fresh, floral, rosy, and citrusy scent. The “dl-” prefix indicates it’s a racemic mixture.

This list contains a diverse range of scent profiles, including floral (Benzyl salicylate, Geraniol, Linalool, Nerol, Piperonal, Tetrahydrolinalool, alpha-Hexylcinnamaldehyde, delta-Damascone, dl-Citronellol), woody/ambery/musky (Iso E Super), and sweet (Coumarin). As always, it is important to be aware of potential allergens, such as Benzyl salicylate and alpha-Hexylcinnamaldehyde (HCA).
