What it is
Glyceryl dioleate is formed by attaching two unsaturated oleic acid chains to a glycerin backbone, producing an oily, lipophilic material. In formulations it imparts a softening, conditioning emollient feel and can assist with phase compatibility. Its oleic content gives it a notably rich, cushiony skin feel.
Safety & warnings
Glyceryl dioleate is generally well tolerated for topical use. Because it is rich in oleic acid, an unsaturated fatty acid, it is more likely than lighter esters to feel occlusive and may be a consideration for those prone to clogged pores in heavier formulas. It is not a recognized fragrance allergen.
Origin & sourcing
It is produced synthetically by esterifying glycerin with oleic acid, a monounsaturated fatty acid commonly obtained from plant oils.
Questions everyone asks
What makes glyceryl dioleate feel rich?
It carries two oleic acid chains on the glycerin backbone, which makes it more oily and gives products a softer, more cushioned emollient feel.
Is it suitable for oily or acne-prone skin?
As an oleic-rich lipid it can feel occlusive, so those prone to clogged pores may prefer lighter esters, though tolerance varies and it is usually present at modest levels.
