Pexalyn® Ester 10

Pexalyn® Ester 10 rosin, a hard, pale, thermoplastic rosin, is a glycerol ester of partially dimerized rosin. It has a higher softening point than typical glycerol esters of wood or gum rosin, as well as improved color stability and solution properties. Pexalyn Ester 10 rosin is indicated for use in wax formulations to control viscosity and enhance rheological properties. It is also recommended for use as a modifier for mascara and similar cosmetic applications, where its broad solubility and compatibility are particularly beneficial, and as a tackifier resin for various types of adhesives.

Storage and Inventory Control

Pastillated or flaked resins may fuse, block, or lump during hot weather months, if stored near sources of heat, if double or triple stacked, or if stored for prolonged periods of time. These forms of resin are prone to gradual oxidation, some more so than others. This could result in darkening and/or could have an adverse effect on solubility in organic solvents. Care should be given to minimize opportunities for product oxidation throughout processing. Accordingly, it is strongly recommended that proper storage conditions and strict control of inventory be observed at all times, taking care that the oldest material is used first.
