Potassium Behenate ●
TL;DR. This ingredient functions mainly as a soap-type surfactant and emulsifier, helping disperse oils in water while adding structure and a firmer feel to creams, sticks, and cleansing products.
What does Potassium Behenate do in a cosmetic formula?
This ingredient functions mainly as a soap-type surfactant and emulsifier, helping disperse oils in water while adding structure and a firmer feel to creams, sticks, and cleansing products.
Is Potassium Behenate clean?
From a clean-beauty perspective, it is generally straightforward: a fatty-acid-derived material with low controversy and no major restricted-list profile. Like other soap-type materials, it can feel drying or irritating in formulas with a higher pH, especially around the eyes or on reactive skin.
Is Potassium Behenate sustainable?
This material is commonly made from long-chain fatty acids that can come from vegetable oils, so sourcing depends on the specific supply chain. It is expected to be readily biodegradable and does not raise the persistence concerns associated with many synthetic film-formers or silicones.
Is Potassium Behenate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic formulation principles when made from permitted natural-origin fatty acids and potassium hydroxide. Its Green Chemistry profile is favorable because it uses simple neutralization chemistry, renewable feedstock options, and a biodegradable fatty-acid backbone.
How does Potassium Behenate work chemically?
The molecule is an ionic amphiphile built from a C22 saturated hydrocarbon chain and a potassium carboxylate head group, giving it both oil-affinity and water-dispersibility. It performs best in neutral-to-alkaline systems, can lose performance in hard water or high-electrolyte formulas, and is usually used at low single-digit levels when included as an emulsifying or structuring soap.
