Science
Mechanism of Action
As an amphiphilic polyglyceryl ester, Polyglyceryl-5 Dioleate actively reduces the interfacial tension between otherwise immiscible components, such as oils and aqueous solutions. Its distinct hydrophilic and lipophilic domains enable it to encapsulate and stabilize dispersed phases, thereby preventing phase separation and ensuring the sustained homogeneity of cosmetic formulations.

Dusting Analysis
Polyglyceryl-5 Dioleate functions as an emulsifying agent, typically incorporated at formulation-critical percentages rather than as an active ingredient requiring micro-dosing for efficacy.

Stability
This polyglycerol fatty acid ester demonstrates robust stability across a wide pH range and diverse temperature conditions. Its functional integrity remains largely unaffected by high salt concentrations, enabling the formation of highly stable emulsions with excellent heat and cold resistance.
Safety
Safety Profile
While a related compound, Polyglyceryl-5 Oleate, is broadly recognized as safe for cosmetic applications, Polyglyceryl-5 Dioleate may occasionally induce mild irritation in sensitive individuals, warranting preliminary patch testing. Clinically, it is important to note its potential to contribute to the proliferation of fungal acne.
