Description
1,3-Distearin (CAS 504-40-5) is a symmetric diglyceride formed from glycerol esterified with two stearic acid chains at the sn-1 and sn-3 positions. Also referenced as 1,3-glyceryl distearate or NSC 404229, it carries no assigned E-code and is distinct from the more common 1,2-isomer in both structure and functional behaviour.
In food and pharmaceutical formulations, 1,3-distearin acts as a structuring agent and emulsifier by forming stable beta-prime crystal networks that control fat crystallisation and texture in margarines, coatings, and lipid-based drug delivery systems. In personal care, it modifies rheology in anhydrous systems by increasing viscosity and improving film cohesion without added water.
1,3-Distearin is supplied as a solid, typically in powder or flake form, and is available in food-grade and pharmaceutical-grade specifications. Procurement should confirm compliance with REACH registration requirements and request a certificate of analysis aligned to FCC or Ph.Eur. monograph standards where applicable.
