Triacetin, chemically known as glycerol triacetate or 1,2,3-triacetoxypropane, is a highly versatile organic compound with the CAS number 102-76-1. This colorless, odorless, and viscous oily liquid plays a significant role across a multitude of industries due to its unique properties. For procurement managers and R&D scientists seeking high-quality chemical intermediates, understanding Triacetin's characteristics and applications is paramount. If you are looking to buy Triacetin or source it from a dependable supplier, this guide will illuminate its key attributes and industrial relevance.

Key Properties and Chemical Nature

Triacetin is the triester of glycerol and acetic acid, boasting a molecular formula of C9H14O6. Its notable attributes include excellent solvency power, low volatility, and miscibility with common organic solvents like ethanol and ether, while showing slight solubility in water. With a purity level typically exceeding 99%, it is favored in applications where high standards are critical. Its non-toxic and non-irritating nature further enhances its appeal for use in consumer products.

Diverse Industrial Applications

The versatility of Triacetin makes it an indispensable ingredient in several sectors. As a plasticizer, it enhances the flexibility and durability of materials such as cellulose acetate, ethyl cellulose, and resins, finding its way into products like cigarette filter tips and flexible plastics. Its role as a solvent is crucial in the flavor and fragrance industry, where it helps dissolve and fix aromatic compounds, ensuring a stable and prolonged scent profile. In the cosmetics and personal care industry, Triacetin acts as a humectant, solvent, and fixative, contributing to product texture and stability in lotions, creams, and perfumes.

Furthermore, Triacetin serves as a valuable food additive (E1518) in many regions, acting as a solvent for flavorings and a humectant in baked goods and confectionery. Its utility extends to the pharmaceutical sector as an excipient, aiding in drug solubility and stability in various formulations. The compound also finds application as a fuel additive to improve combustion and is explored for its potential in biodegradable systems for drug delivery.

Sourcing Triacetin: What Buyers Need to Know

When seeking to buy Triacetin, procurement professionals should prioritize suppliers who can guarantee high purity, consistent quality, and reliable supply chains. Manufacturers in China are often competitive sources for industrial-grade Triacetin. Key specifications to look for include purity levels (e.g., 99% min), color (colorless transparent liquid), and low water content. Understanding the specific grade required—whether for industrial, cosmetic, pharmaceutical, or food applications—is essential. Engaging with a reputable Triacetin supplier means ensuring compliance with regulatory standards and securing transparent pricing. For those interested in purchasing bulk quantities, obtaining a quote from established manufacturers is the first step toward a strategic partnership.

In summary, Triacetin (CAS 102-76-1) is a chemical workhorse with broad applicability. Its advantageous properties as a solvent, plasticizer, and humectant make it a sought-after commodity. By focusing on quality specifications and partnering with reliable manufacturers, businesses can effectively leverage Triacetin to enhance their product offerings and manufacturing processes.
