Potassium Laurate ●
TL;DR. This ingredient is an anionic soap surfactant used for cleansing, foaming, and emulsifying, especially in liquid soaps and high-pH cleansers. It helps lift oils from skin and hair by forming micelles.
What does Potassium Laurate do in a cosmetic formula?
This ingredient is an anionic soap surfactant used for cleansing, foaming, and emulsifying, especially in liquid soaps and high-pH cleansers. It helps lift oils from skin and hair by forming micelles.
Is Potassium Laurate clean?
From a clean-beauty perspective, it is a familiar soap ingredient with no broad restricted-list issue, but its naturally alkaline profile can feel drying or sting on sensitive or barrier-compromised skin. The main formulation question is final pH, not a hidden contaminant concern.
Is Potassium Laurate sustainable?
This material is commonly made from coconut or palm-kernel-derived C12 fatty acids plus mineral alkali, so sourcing traceability matters when palm inputs are involved. It is expected to biodegrade readily and does not raise major persistence concerns in rinse-off use.
Is Potassium Laurate COSMOS-approved?
It can be permitted under COSMOS-natural or COSMOS-organic when made from allowed fatty-acid sources and approved processing routes such as neutralization or saponification. Its Green Chemistry fit is reasonable because it can use renewable lipids and has good biodegradability, although alkaline processing and palm-linked sourcing can be caveats.
How does Potassium Laurate work chemically?
The molecule is an alkali-metal carboxylate, with a hydrophilic ionic head and a C12 saturated hydrocarbon tail that gives it strong detergency and foam. It performs best in alkaline systems, often around pH 9 to 11, and can lose performance in hard water through formation of insoluble fatty-acid salts.
