Dimethyl Lauramide/Myristamide ●
TL;DR. This ingredient is used mainly as a foam booster, viscosity modifier, and solubilizing co-surfactant in rinse-off cleansing products. It helps improve lather texture and can help dissolve oily fragrance or active components into surfactant systems.
What does Dimethyl Lauramide/Myristamide do in a cosmetic formula?
This ingredient is used mainly as a foam booster, viscosity modifier, and solubilizing co-surfactant in rinse-off cleansing products. It helps improve lather texture and can help dissolve oily fragrance or active components into surfactant systems.
Is Dimethyl Lauramide/Myristamide clean?
From a clean-beauty perspective, this ingredient is acceptable but not especially simple. The main scrutiny is around synthetic processing, residual amines, and nitrosamine-control documentation rather than routine skin tolerability at typical rinse-off levels.
Is Dimethyl Lauramide/Myristamide sustainable?
This material is usually built from C12 to C14 fatty chains that may come from coconut, palm kernel, or petrochemical-linked sources depending on the supplier. It is expected to biodegrade more readily than silicone or fluorinated materials, but sourcing traceability matters because the fatty feedstock can be tied to palm supply chains.
Is Dimethyl Lauramide/Myristamide COSMOS-approved?
It is not a straightforward COSMOS-organic ingredient, and acceptance depends on whether the fatty feedstock, reaction route, and impurity controls meet the standard’s criteria for chemically processed agro-ingredients. Its Green Chemistry profile is mixed, with renewable-chain potential and good functional efficiency, balanced by synthetic amide chemistry and the need for residual-reactant controls.
How does Dimethyl Lauramide/Myristamide work chemically?
The molecule is a nonionic fatty acid amide with two methyl groups on nitrogen and a mainly C12 to C14 hydrophobic tail, giving it both oil-solubilizing and surfactant-compatible behavior. It is most often used in rinse-off surfactant blends at low single-digit percentages, and formulators manage it alongside pH, salt response, fragrance load, and preservative compatibility.
