PEG-15 Cocopolyamine
INCI: PEG-15 Cocopolyamine
PEG-15 Cocopolyamine is a synthetic surfactant that helps cleanse and reduce static in hair, but it may cause mild irritation for sensitive skin.
In plain English
PEG-15 Cocopolyamine is a man-made ingredient that helps products like shampoo and body wash clean your skin and hair by breaking down dirt and oil. It also helps reduce static electricity in hair, making it less frizzy. Because it's a surfactant, it can be drying or slightly irritating for people with very sensitive or dry skin, especially if used in high amounts.

What it is
PEG-15 Cocopolyamine is a polyethylene glycol (PEG) derivative of cocoamine, a fatty amine derived from coconut oil. It is a synthetic surfactant and conditioning agent.
How it works
In a cosmetic product, PEG-15 Cocopolyamine works by reducing the surface tension between water and oils, allowing dirt and excess sebum to be rinsed away. It also carries a positive charge that helps it adhere to hair and skin, providing antistatic and conditioning effects.
Pros
Effective cleanser
Removes excess oil and buildup without leaving a heavy film, making it suitable for oily hair and skin types.
Reduces hair static
Its antistatic properties help control flyaways and frizz, especially in humid conditions.
Cons and cautions
Potential irritation
Can cause mild stinging or dryness for those with sensitive or compromised skin barriers, especially in high concentrations.
Synthetic origin concerns
As a PEG derivative, it may be associated with contamination concerns during manufacturing, though reputable brands use purified versions.
Best for
- People with normal to oily hair or skin
- Those looking for effective cleansing without heavy residue
Use caution if
- Individuals with very sensitive, dry, or eczema-prone skin
- Those who prefer entirely natural or PEG-free formulations
Usage tips
