Description

Polyglyceric Acid CAS NO 118916-26-0 is a versatile polyfunctional carboxylic acid derived from glycerol, offering a unique combination of hydrophilic character and multiple reactive sites. This compound is valued for its ability to act as a building block, crosslinker, or modifier in advanced polymer and material synthesis. It is particularly sought after by R&D and production teams in the pharmaceutical intermediates, specialty polymers, and personal care ingredient sectors seeking to enhance product performance through tailored chemical functionality.

Application

• Pharmaceutical Intermediates: Serves as a key synthon for constructing complex drug molecules, prodrugs, and biodegradable polymer carriers for controlled release.
• Specialty Polymer Synthesis: Used as a crosslinking agent or co-monomer to produce polyesters, polyamides, and hydrogels with tailored solubility, biodegradability, and mechanical properties.
• Personal Care & Cosmetics: Functions as a skin-conditioning agent, emulsifier, or viscosity modifier in formulations due to its humectant and film-forming potential.
• Adhesives & Resins: Incorporated to improve adhesion, flexibility, and water resistance in epoxy curing agents, alkyd resins, and polyurethane systems.
• Lubricant & Fuel Additives: Acts as a precursor for synthesizing ester-based additives that improve lubricity, stability, and anti-wear properties.
• Chelating Agents: Its structure allows for the development of novel, biodegradable chelating agents for water treatment or metal ion sequestration.

Quality Control

Our Polyglyceric Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance. We provide detailed Certificates of Analysis (COA) with key parameters such as acid value, hydroxyl value, degree of polymerization, and residual solvent content. Our quality commitment supports applications requiring reliable and traceable raw materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to minimize moisture absorption, which can affect product stability and performance. Keep away from incompatible materials such as strong bases and oxidizing agents.
