Dimethyl succinate

CAS: 106-65-0

Overview

Dimethyl succinate (CAS 106-65-0 ), also known by FEMA 2396 , is a diester solvent and flavoring agent used across personal care formulation and food manufacturing. It functions as a carrier solvent and humectant.

In food and beverage manufacturing, dimethyl succinate delivers a mild fruity, wine-like flavor note. It is used in flavoring systems for confectionery, baked goods, and beverages under regulatory approval.

Personal care formulators use it as a low-viscosity carrier solvent to improve spreadability and skin feel in emollients and lotions. Its humectant behavior supports moisture retention in leave-on cosmetic formulations.

This material is a practical alternative to heavier ester solvents in fragrance delivery systems. It also functions as a co-solvent in fragrance concentrates, helping to solubilize aromatic ingredients at controlled dilution.

Dimethyl succinate is supplied as a clear liquid in drum and IBC quantities suited to both industrial and specialty formulation volumes. This ensures reliable logistics for large-scale manufacturing needs.

Food-grade material conforming to established standards is the primary commercial specification for flavor and cosmetic applications. Technical-grade material is available for solvent and process applications.

Whether used for its aromatic properties or its solvent capabilities, this diester provides consistent performance. It remains a versatile component for chemists developing modern consumer and industrial products.
