Palm Stearic Acid ●
TL;DR. This ingredient is a fatty structurant and consistency builder used to thicken creams, lotions, balms, and cleansing bars. It also helps stabilize emulsions and gives formulas a denser, creamier feel.
What does Palm Stearic Acid do in a cosmetic formula?
This ingredient is a fatty structurant and consistency builder used to thicken creams, lotions, balms, and cleansing bars. It also helps stabilize emulsions and gives formulas a denser, creamier feel.
Is Palm Stearic Acid clean?
It is generally well tolerated, not a common allergen, and has little clean-standard friction when made and purified appropriately. The main scrutiny is sourcing transparency rather than routine skin compatibility.
Is Palm Stearic Acid sustainable?
This material is plant-derived and readily biodegradable, but it is tied to a tropical oil-crop supply chain with land-use and traceability concerns. Certified responsible sourcing, such as RSPO-linked supply, materially improves its sustainability profile.
Is Palm Stearic Acid COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when derived from accepted natural feedstocks and processed with allowed chemistry. Its Green Chemistry fit is solid on biodegradability and renewable carbon, with the main weakness being agricultural sourcing impact.
How does Palm Stearic Acid work chemically?
The molecule is a long-chain C18 saturated fatty acid with a polar carboxyl group and a waxy hydrophobic tail, which explains its thickening and co-emulsifying behavior. It is commonly used around 1 to 10 percent depending on product type, melts near 69 to 70°C, and is relatively oxidation-stable because it has no carbon-carbon double bonds.
