PEG-15 Cocamine

What PEG-15 Cocamine is & what it does

PEG-15 Cocamine is an ethoxylated amine derived from the fatty acids of coconut oil reacted with ethylene oxide. In formulas it functions mainly as an emulsifier and surfactant, helping to mix oil and water phases and to disperse other ingredients. It can also act as an antistatic or solubilizing agent depending on the product.

What does PEG-15 Cocamine do in skincare?

PEG-15 Cocamine is an ethoxylated amine derived from coconut fatty acids. It functions mainly as an emulsifier and surfactant, helping to mix oil and water and to disperse other ingredients evenly. It can also help solubilize or stabilize a formula.

Is PEG-15 Cocamine natural or synthetic?

It is best described as synthetic but partly nature-derived: the fatty portion comes from coconut oil, while the PEG part is made by reacting it with ethylene oxide. This ethoxylation step is a synthetic process. The result is a processed surfactant rather than a natural ingredient.

Is PEG-15 Cocamine vegan?

The coconut-derived portion is plant-based, and the ethoxylation uses synthetic inputs, so the ingredient is generally compatible with vegan formulas. As with many surfactants, exact sourcing can vary by supplier. Check with the brand if confirming a vegan product matters to you.
