Description

Polyethylene-Polypropylene Glycol Diacetate is a versatile, non-ionic polymeric ester derived from the acetylation of a polyethylene-polypropylene glycol block copolymer. This compound is valued for its dual functionality as a solubilizer and a mild, non-volatile solvent, making it an effective intermediate and additive in advanced formulations. It is primarily sought after by manufacturers in the pharmaceutical, personal care, and specialty chemical industries for its ability to modify solubility and enhance the delivery of active ingredients.

Application

• Pharmaceutical Excipient: Used as a solubilizing agent and co-solvent in topical formulations, transdermal patches, and oral solutions.
• Personal Care & Cosmetics: Functions as a skin-conditioning agent, emollient, and carrier for fragrances or active compounds in creams, lotions, and serums.
• Polymer Plasticizer: Acts as an internal plasticizer and processing aid to improve the flexibility and workability of certain resins and elastomers.
• Chemical Intermediate: Serves as a key building block in the synthesis of more complex surfactants and specialty esters.
• Industrial Additive: Employed as a lubricant additive or a component in specialty cleaning and degreasing formulations.

Quality Control

Our Polyethylene-Polypropylene Glycol Diacetate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. While specific grades are available, our standard quality commitment includes verification of key parameters such as acetyl value, hydroxyl value, and molecular weight distribution. Certificates of Analysis (COA) are provided and can be tailored to meet specific customer or regulatory requirements, including those for pharmaceutical (GMP) or cosmetic applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
