PEG-100 Hydrogenated Castor Oil

PEG-100 Hydrogenated Castor Oil is a surfactant and emulsifier derived from castor oil that has been hydrogenated (chemically saturated with hydrogen) and combined with polyethylene glycol (PEG). This modification allows it to function as a bridge between oil and water-based ingredients, helping them remain mixed and stable in skincare formulations.In cosmetics, it serves a structural role rather than a direct skin-active one. It's commonly used in cleansers, serums, and other products where ingredients of different polarities need to coexist without separating.

PEG-100 Hydrogenated Castor Oil works as an emulsifier by positioning itself at the boundary between oil and water phases. One part of its molecular structure attracts oils, while another attracts water, effectively holding them together in suspension.From a sensory perspective, this creates a more uniform product texture and can improve how actives are distributed during application. It does not penetrate skin or alter skin function directly.

No special usage guidance is needed for this ingredient — it functions as a formulation component rather than something requiring specific application technique. Use products containing it as directed on the label. If you have fungal acne concerns, introduce new products gradually and monitor your skin's response.

PEG-100 Hydrogenated Castor Oil is generally well-tolerated and approved for cosmetic use in most regulatory regions. Those with suspected fungal acne or sensitivities to emulsifiers should patch-test first.
