Glyceryl dioleate

Glyceryl dioleate (CAS 25637-84-7 ), also known as Diolein, is a diester of glycerol and oleic acid used across personal care, food, and industrial formulations. It functions primarily as an emulsifier, skin-conditioning agent, and lubricant.

This versatile compound bridges oil and water phases or reduces friction in mechanical systems. In personal care formulations, it stabilizes oil-in-water and water-in-oil emulsions in creams, lotions, and serums.

The ingredient delivers a smooth, non-greasy skin feel to cosmetic products. Food manufacturers use it as an emulsifier in fat-based products, bakery fillings, and confectionery coatings where consistency is required.

It is particularly effective where controlled crystallization and texture consistency are required. In lubricant and metalworking fluid formulations, its oleic acid backbone provides essential boundary lubrication.

This reduces wear on metal surfaces during cutting and forming operations. It also acts as a dispersing agent in pigment concentrates and oleophilic systems where uniform distribution of components is critical.

Glyceryl dioleate is supplied as a pale yellow to amber liquid at ambient temperature. It is available in cosmetic-grade and food-grade ( FCC ) specifications, with purity levels defined by specific ratios.

The quality is typically defined by monoglyceride/diglyceride ratio and acid value. Technical-grade material is also offered for industrial lubricant and metalworking applications to meet diverse industrial needs.
