PEG-15 Cocopolyamine

PEG / Ethoxylated

What is PEG-15 Cocopolyamine?

PEG-15 Cocopolyamine is a modified fatty amine derived from coconut oil fatty acids, chemically processed through ethoxylation with 15 units of polyethylene glycol and amination to create a cationic polymer. This gives it positively charged sites that interact with negatively charged hair surfaces. Primarily found in rinse-off hair care formulations like conditioners, detanglers, and styling aids, it works by depositing a conditioning film that neutralizes static charges, improves slip for easier combing, and facilitates the blending of oily and watery ingredients. Its surfactant properties help disperse oils and soils during cleansing without stripping hair excessively, while emulsifying action ensures product stability and even application. The PEG chain enhances water solubility and mildness compared to non-ethoxylated amines.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Antistatic agent
Reduces static electricity and flyaways by improving surface conductivity, enhancing hair manageability and smoothness in conditioners and styling products.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits

Reduces static buildup on hair for smoother, more manageable strands.

Supports gentle cleansing by lowering surface tension to remove dirt and oils.

Stabilizes emulsions in formulas for consistent texture and performance.
