Trimofix aka. Amber Decatriene alt. Fixamber Aroma Chemical
CAS# 144020-22-4

Trimofix is a prominent trade name produced by IFF and is also widely known under other names such as Amber Decatriene or Fixamber. This compound is associated with CAS Nos. 144020-22-4 and 28371-99-5, representing mixtures of structural isomers used commercially. It is a fully synthetic aroma material, developed through chemical research aimed at creating an ambery-woody note with pronounced musky and tobacco-like nuances. In appearance, it is a clear to pale yellow liquid. Today, the material is widely used to add depth to products ranging from fine fragrances to home-care applications. Historically, the compound was developed and commercialized toward the end of the 20th century. Because it appeared relatively late, Trimofix is entirely absent from Steffen Arctander’s classic reference work Perfume and Flavor Chemicals, Volumes 1 and 2, published in 1969, as the material had not yet been invented when the book was released.

Description

Belonging to the woody, ambery, and musky fragrance family, Trimofix functions primarily as a base note, acting as an effective fixative and fragrance modifier that imparts warmth to the overall composition. Its odor profile is highly complex, combining the dryness of wood and the deep warmth of amber with nuances reminiscent of vetiver, tobacco leaf, and a slightly animalic musk character.

The material has a strong odor intensity, consistent diffusion, and exceptional substantivity, with its scent potentially remaining detectable on a smelling strip for several weeks. In fragrance formulations, Trimofix is used to construct a solid woody backbone, providing a foundation that links spicy notes together while creating a pronounced sense of depth.

One of its most technically effective combinations is with Iso E Super, Ambroxan, vetiver essential oil, and polycyclic musks to create a rich, masculine olfactory environment. Because of its relatively high odor strength, perfumers often dilute Trimofix in suitable solvents such as Dipropylene Glycol (DPG) or Triethyl Citrate (TEC) at concentrations of 10% or 50% to facilitate accurate weighing, dosing, and handling.

Applications

Thanks to its ability to create a multidimensional woody-amber effect and its excellent chemical stability, Trimofix has a broad range of applications, including fine fragrances, home-fragrance products, leave-on cosmetics, rinse-off cosmetics, and soaps.

According to standards established by the International Fragrance Association (IFRA), this material is regarded as having a favorable safety profile and is not subject to particularly stringent usage restrictions based on toxicity, with typical reference usage levels generally ranging from 1% to 10%, depending on the structure and character of the finished product.

From a safety perspective, the compound is not considered phototoxic and is not included among the fragrance allergens that must be individually declared on product labels. Users should nevertheless follow standard handling practices, store the material in a cool, well-ventilated place, and avoid direct contact of the undiluted material with the eyes.

In today’s market, Trimofix is rarely highlighted individually on product packaging because of commercial confidentiality surrounding fragrance formulations. Nevertheless, it serves as an important core material in the construction of commercial woody and tobacco bases, contributing directly to the character of many contemporary unisex and masculine Oriental-style fragrances in which woody, amber, and musky themes are strongly emphasized.
