Sodium Stearate1 ●
TL;DR. This ingredient is primarily an anionic structurant and cleansing aid, used to firm bars, thicken stick formats, stabilize emulsions, and add mild foam or slip.
What does Sodium Stearate1 do in a cosmetic formula?
This ingredient is primarily an anionic structurant and cleansing aid, used to firm bars, thicken stick formats, stabilize emulsions, and add mild foam or slip.
Is Sodium Stearate1 clean?
It is generally well accepted in clean-beauty frameworks and is not a common restricted-list concern. The main watchpoint is formula pH, since alkaline systems can feel drying or irritating on sensitive skin.
Is Sodium Stearate1 sustainable?
This material is typically made from fatty acids that may come from plant oils or animal-derived sources, so sourcing transparency matters, especially when palm-derived feedstocks are involved. It is readily biodegradable and does not raise meaningful persistence concerns in rinse-off use.
Is Sodium Stearate1 COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when made from allowed fatty-acid feedstocks using accepted processing. From a Green Chemistry view, it aligns well when renewable inputs are used and processing is simple saponification with good biodegradability.
How does Sodium Stearate1 work chemically?
The molecule is a long-chain anionic carboxylate salt, which gives it both oil-compatible and water-interacting regions for structuring and cleansing behavior. It is most effective in alkaline formulas, can lose performance in acidic systems, and can interact with hard-water minerals to form insoluble deposits.
