Description

Dioctyl Phthalate, commonly known as DOP, is a low-volatility, low-odor functional ingredient rather than a conventional perfumery aroma chemical. It is primarily valued for its physical properties as a solvent, carrier and plasticizing material. In fragrance-related applications, its relatively neutral odor allows it to be used without significantly changing the intended odor profile of a fragrance composition.

In formulation work, DOP can help dilute and carry concentrated fragrance materials and improve the handling of certain fragrance blends. Its low volatility can also be useful where a stable carrier is required. However, its suitability depends strongly on the intended application, local regulations and the requirements of the finished product. It should therefore be selected based on the specific formulation and regulatory framework rather than treated as an odor-active perfume ingredient.

Perfumers' Tip

DOP should be considered primarily a functional carrier rather than an odor material. Before using it in a finished consumer product, verify that it is appropriate and permitted for the specific application and market, as regulatory requirements can vary considerably.
