What Is Potassium Borageate?

Potassium borageate is a potassium salt derived from borage oil, a plant-derived ingredient rich in gamma-linolenic acid (GLA). In skincare formulations, it serves as a surfactant and cleansing agent, helping to remove impurities and oil from the skin surface.

As a mild surfactant, potassium borageate works to lift dirt and excess sebum without the harshness associated with stronger cleansing agents. It is typically used in rinse-off products such as cleansers and body washes where its cleansing properties are most effective.

How It Works

Potassium borageate functions as a surfactant, meaning it has both water-loving and oil-loving properties. This dual affinity allows it to suspend oils and water-soluble dirt in a cleansing formula, enabling them to be rinsed away more easily during the cleanse.

Because it is derived from borage oil rather than petroleum, it is generally considered a milder alternative to conventional synthetic surfactants, making it a suitable choice for formulations designed to cleanse without over-drying the skin.

Clinical Evidence & References

Research on potassium borageate as a standalone skincare ingredient is limited. Most evidence for its efficacy comes from its use in cleansing formulations alongside other ingredients, where it contributes to overall cleansing performance.

Borage oil itself has been studied for its GLA content and potential skin-conditioning properties, but specific clinical data on potassium borageate's isolated effects on skin remain sparse. It is generally recognised as a safe and effective mild surfactant in cosmetic use.

How to Use

Potassium borageate is used in rinse-off products, so apply to damp skin, massage gently, and rinse thoroughly with water. Because it is a mild cleanser, it is suitable for daily use in facial or body cleansers. Follow with your chosen toner or moisturiser to maintain hydration.

Safety & Precautions

Potassium borageate is generally well-tolerated and considered safe for cosmetic use. As with any cleansing agent, discontinue use if irritation or sensitivity occurs.
