Description

3-[(2-Hydroxydodecyl)Oxy]Propane-1,2-Diol CAS NO 2984-32-9 is a specialized non-ionic surfactant and polyol derivative, valued for its unique amphiphilic structure combining a long alkyl chain with a hydrophilic glycerol backbone. This compound is essential for formulators seeking to create stable emulsions and enhance the solubility of active ingredients in complex matrices. It is primarily utilized in the personal care, pharmaceutical, and specialty chemical industries for its emulsifying, solubilizing, and conditioning properties.

Application

• Cosmetic & Personal Care Formulations: Acts as a key emulsifier and skin-conditioning agent in creams, lotions, and sunscreens.
• Pharmaceutical Excipient: Used as a solubilizer and stabilizer in topical drug delivery systems and ointments.
• Industrial Surfactant: Employed in the formulation of specialty cleaners, textile processing aids, and agrochemical emulsions.
• Lubricant & Metalworking Additive: Serves as a component in synthetic lubricants and corrosion inhibitor formulations.
• Polymer & Resin Modification: Functions as a reactive intermediate or plasticizer in the synthesis of polyurethanes and alkyd resins.

Quality Control

Our production of 3-[(2-Hydroxydodecyl)Oxy]Propane-1,2-Diol adheres to stringent quality management protocols. Every batch is tested against comprehensive specifications to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, moisture content, and impurity profiles. We support compliance with REACH and other relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to mitigate potential oxidation.
