Triglycerin

Triglycerin (CAS 56090-54-1), also known as triglycerol or triglycerine and traded under designations such as PGL-S and PGL 03P, is a polyol formed by the condensation of three glycerol units. It carries no assigned E-code and is classified under the Alcohols & Glycols category with the molecular formula C9H20O7.

In personal care formulations, triglycerin functions as a humectant by attracting and retaining moisture within the skin matrix, improving texture stability in emulsions. In food and coatings applications, its multiple hydroxyl groups support emulsification by reducing interfacial tension between oil and water phases, and it serves as a polar carrier solvent for active ingredients.

Triglycerin is supplied in compliance with REACH regulations and is available in grades suitable for cosmetic and food-contact applications. Procurement teams should confirm grade specification, purity documentation, and packaging format directly with the supplier, as these vary by production batch and regional distribution.
