Description

Pentyl Stearate is a high-purity ester compound, also known as amyl stearate, valued for its excellent lubricity, stability, and hydrophobic properties. It serves as a versatile intermediate and functional additive, providing smooth texture, plasticizing effects, and water resistance to formulations. This product is essential for manufacturers in the cosmetics, plastics, lubricants, and textile industries seeking reliable performance additives.

Application

• Cosmetics & Personal Care: Acts as an effective emollient, skin-conditioning agent, and viscosity modifier in creams, lotions, and makeup products.
• Plastic & Polymer Industry: Functions as an internal and external lubricant and plasticizer in PVC, polystyrene, and other polymer processing to improve flow and surface finish.
• Lubricants & Greases: Used as a synthetic base oil or additive in specialty lubricants, metalworking fluids, and release agents due to its low pour point and good film strength.
• Textile & Fiber Processing: Employed as a softening agent, spin finish, and lubricant for synthetic fibers and yarns to reduce friction and static.
• Rubber Manufacturing: Serves as a processing aid and mold release agent to facilitate mixing, extrusion, and demolding.
• Coatings & Inks: Imparts leveling and flow properties while enhancing water repellency in various coating and ink formulations.
