Glyceryl Tristearate

Glyceryl Tristearate (CAS 555-43-1), also known as Tristearin, is a fully saturated triglyceride derived from glycerol and stearic acid. It functions as an emulsifier, stabilizer, and lubricant across food, pharmaceutical, personal care, and industrial applications.

Its high melting point and solid waxy form make it a preferred structuring and release-control agent in solid-format products. In pharmaceutical manufacturing, it acts as a matrix-forming excipient in sustained-release tablets.

It is utilized in lipid-based drug delivery systems, controlling active ingredient release rates. Confectionery and food producers use it as a bloom inhibitor and texture modifier in chocolate and fat-based coatings, improving shelf stability.

Personal care formulators incorporate it into stick formats such as lip balms, deodorants, and solid lotions. In these applications, it provides structural rigidity and a smooth skin feel for the end consumer.

In industrial lubricants and metalworking compounds, it serves as a base component or additive. It is particularly useful where a solid, high-melting fat with low reactivity is required for specific manufacturing processes.

Glyceryl Tristearate is supplied as a white to off-white powder, flakes, or waxy solid. Food-grade and pharmaceutical-grade material is available, with pharmaceutical supply conforming to USP and Ph.Eur. specifications.

Technical-grade material is also offered for industrial lubricant and coating applications. This ensures that the product meets the diverse requirements of various global manufacturing sectors and quality protocols.
