Description

Octadecanoic Acid, 12-Hydroxy-, Homopolymer, Ester With 1,2,3-Propanetriol Homopolymer is a high-purity, synthetic polymer ester derived from ricinoleic acid and glycerol, designed for advanced industrial applications. This specialized chemical offers exceptional performance as a multifunctional additive, providing unique rheological modification, lubrication, and surface activity. It is a critical raw material for manufacturers in the cosmetics, pharmaceuticals, plastics, and specialty coatings industries seeking consistent quality and reliable supply for their high-value formulations.

Application

• Cosmetics & Personal Care: Acts as a high-efficiency emulsifier, thickener, and emollient in creams, lotions, lipsticks, and sunscreens, providing a smooth texture and stable formulations.
• Pharmaceuticals: Used as a non-ionic surfactant and solubilizing agent in topical drug delivery systems, ointments, and controlled-release matrices.
• Polymer & Plastics Industry: Functions as an internal lubricant, processing aid, and anti-static agent in PVC, polyolefins, and engineering plastics to improve flow and mold release.
• Specialty Coatings & Inks: Serves as a dispersing agent and viscosity modifier, enhancing pigment wetting and providing superior gloss and leveling in high-performance coatings and printing inks.
• Food-Grade Lubricants & Additives: Employed as a base or additive in formulations requiring NSF H1 registration for incidental food contact due to its non-toxic profile.
• Adhesives & Sealants: Imparts tackifying and plasticizing properties, improving adhesion and flexibility in hot-melt and pressure-sensitive adhesive systems.

Quality Control

Our Octadecanoic Acid, 12-Hydroxy-, Homopolymer, Ester With 1,2,3-Propanetriol Homopolymer is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, acid value, hydroxyl value, and viscosity. We provide full traceability and Certificates of Analysis (COA) are available for every shipment. Production can be aligned with relevant standards such as FCC (Food Chemicals Codex) for food-grade applications and in compliance with global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C / 59-77°F). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture which can affect product performance. Keep away from strong alkalis and incompatible materials.
