Sodium Palmitate ●
TL;DR. This ingredient is an anionic cleansing surfactant and structuring agent, especially in bar cleansers and traditional alkaline wash products. It helps lift oily soil and contributes hardness and opacity to solid formats.
What does Sodium Palmitate do in a cosmetic formula?
This ingredient is an anionic cleansing surfactant and structuring agent, especially in bar cleansers and traditional alkaline wash products. It helps lift oily soil and contributes hardness and opacity to solid formats.
Is Sodium Palmitate clean?
Clean-beauty frameworks generally accept this ingredient, with the main caveat being that high-pH formulas can feel drying or irritating on sensitive skin. It is not a common restricted-list concern, but formula pH matters more than the ingredient alone.
Is Sodium Palmitate sustainable?
This material is usually made from fatty acid feedstocks that may be plant-derived, animal-derived, or palm-linked, so sourcing transparency is relevant. It is readily biodegradable and does not raise major persistence concerns in rinse-off use.
Is Sodium Palmitate COSMOS-approved?
It is generally permitted under COSMOS natural and organic standards when made from allowed feedstocks and approved processing chemistry. Its Green Chemistry profile is strongest when sourced from responsibly managed renewable oils, with good biodegradability and simple processing.
How does Sodium Palmitate work chemically?
The molecule is a sodium carboxylate salt of a saturated C16 fatty acid, which forms alkaline aqueous systems and can interact with hard-water minerals to form insoluble deposits. It is commonly used as a major component in cleansing bars, where higher levels create firmness and dense foam, while final product pH is often around 9 to 10.5.
