PEG-3 OLEAMIDE.

Valuable CAS 26027-37-2 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

PEG-3 Oleamide is a versatile nonionic surfactant and emulsifier, expertly engineered to stabilize oil-water mixtures in cosmetic formulations. Its unique amphiphilic structure reduces interfacial tension, forming a protective film that prevents phase separation and maintains product integrity. This makes it crucial for achieving consistent textures and stability across various skincare products.

Summary

Emulsifying Surfactant

Science

Mechanism of Action

PEG-3 Oleamide operates as a nonionic surfactant and emulsifier by leveraging its amphiphilic molecular design. It possesses a hydrophobic oleamide tail and a hydrophilic polyethylene glycol head, enabling it to efficiently adsorb at the oil-water interface. This adsorption significantly reduces interfacial tension, facilitating the formation and stabilization of emulsions by orienting its oleamide tails within the oil phase and its PEG heads in the aqueous phase, creating both a protective film and steric repulsion against droplet coalescence.

Stability

For optimal stability, precise pH monitoring and the use of suitable buffering systems are recommended. Incorporating antioxidants can effectively inhibit potential oxidative degradation. Rigorous purification processes are critical to eliminate unreacted raw materials, catalyst residues, and byproducts, ensuring the purity and performance of the final formulation.

Conflicts

  • Direct application to compromised or damaged skin should be avoided, as PEGs may potentially induce irritation and enhance the absorption of various contaminants into the skin.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The CIR Expert Panel concluded that PEG-3 Oleamide is safe for cosmetic applications when formulated to be non-irritating, indicating careful consideration of concentration and overall product composition. The FDA has approved it for specific, limited use in food. General clinical studies on polyethylene glycols (PEGs) suggest minimal skin irritation and no significant sensitization risk in human subjects.
