Saponins
Saponins are natural compounds found in many plants that create a gentle foaming action in cleansers and shampoos. They work as mild surfactants, helping to lift away dirt and oil without stripping the skin. Shoppers often choose them for their plant-derived, soap-like feel in natural beauty products.
How it works in skincare
In cosmetics and skincare, saponins act as natural surfactants and emulsifiers, reducing surface tension so water can mix with oils and impurities. They produce a soft, creamy lather that effectively cleanses the skin and hair while remaining milder than many synthetic alternatives, making them popular in UK formulations for facial washes, body washes and shampoo bars.
