Propylene Glycol Dioleate (PGDO)

Overview

Propylene Glycol Dioleate (PGDO), also recognized by its INCI name Propylene Glycol Dioleate and CAS Number 85566-23-0, is a versatile and high-performance diester. It is meticulously derived from propylene glycol and oleic acid, undergoing precise esterification to yield a compound with exceptional functional attributes. As a diester, PGDO features two long-chain oleate groups covalently bonded to a central propylene glycol backbone. This unique molecular architecture imparts a combination of lipophilic and polar characteristics, making PGDO an invaluable ingredient across diverse industrial sectors. At CanCastor, our PGDO is engineered for superior performance, offering excellent solvency, lubricity, and emulsifying properties, critical for advanced formulations.

Our commitment to E-E-A-T is reflected in our rigorous manufacturing processes, adhering to global standards like ISO 9001:2015. Through transparent sourcing of high-purity raw materials and advanced synthesis, we ensure that every batch of CanCastor's Propylene Glycol Dioleate consistently meets or exceeds stringent industry specifications, including those relevant for USP, BP, and REACH compliance. This ensures its suitability for applications ranging from pharmaceutical excipients and food-grade emulsifiers to high-performance industrial lubricants and cosmetic emollients.

Key Physical & Chemical Properties

Propylene Glycol Dioleate is a clear to light yellow, odorless liquid at room temperature. Its unique diester structure provides several key performance advantages:

• Low Viscosity: Facilitates ease of handling and formulation integration.
• Excellent Solvency: Acts as a powerful solvent for a wide range of organic compounds, pigments, and active ingredients.
• Superior Lubricity: Reduces friction and wear in mechanical systems, enhancing operational efficiency.
• Good Emulsifying Properties: Aids in stabilizing oil-in-water and water-in-oil emulsions, crucial for many industrial and personal care products.
• Hydrolytic Stability: Demonstrates robust stability under various conditions, ensuring product longevity.
• Skin Compatibility: Often used in dermal applications due to its emollient properties and low irritation potential.
• Biodegradability: Environmentally favorable profile compared to some synthetic alternatives.
