Sodium Stearate
Sodium stearate is a gentle, plant-derived cleansing and emulsifying ingredient commonly found in soaps, cleansers, and solid beauty bars. It helps create a creamy lather, stabilises formulas, and leaves skin feeling soft rather than stripped. A staple in traditional and modern UK skincare and haircare products.
How it works in skincare
In cosmetics and skincare, sodium stearate functions primarily as a surfactant and emulsifier. It reduces surface tension to lift away dirt and excess oil while helping to bind oil and water phases together in creams, lotions, and syndet bars. Its soap-like structure produces a rich, stable foam and imparts a smooth after-feel, making it especially useful in facial cleansers, body washes, shaving creams and solid shampoo bars popular with British consumers.

Where it comes from
Sodium stearate is produced by reacting stearic acid, which is derived from vegetable oils such as palm, coconut or rapeseed oil, with sodium hydroxide. It is a plant-based alternative to animal-derived tallow soaps traditionally used in British cosmetic manufacturing.
