Polyricinoleic Acid ●
TL;DR. This ingredient primarily acts as an emulsifier and dispersing agent, helping oils, waxes, pigments, and water-compatible phases stay evenly distributed. It can also add cushion and conditioning feel in anhydrous or low-water formulas.
What does Polyricinoleic Acid do in a cosmetic formula?
This ingredient primarily acts as an emulsifier and dispersing agent, helping oils, waxes, pigments, and water-compatible phases stay evenly distributed. It can also add cushion and conditioning feel in anhydrous or low-water formulas.
Is Polyricinoleic Acid clean?
From a clean-beauty perspective, it is generally well tolerated and has little restricted-list friction. Sensitivity is uncommon, although very rich oil-based formulas can feel heavy on breakout-prone skin.
Is Polyricinoleic Acid sustainable?
This material is typically made from castor-derived fatty acids, so its feedstock can be renewable rather than petrochemical. It is expected to biodegrade like other fatty acid polyesters, with sourcing quality tied to agricultural practices and traceability.
Is Polyricinoleic Acid COSMOS-approved?
It is generally compatible with COSMOS-natural when made from permitted natural-origin feedstocks using allowed esterification or condensation steps. Its Green Chemistry fit is positive because it uses renewable lipid chemistry and does not require persistent silicone or fluorinated structures.
How does Polyricinoleic Acid work chemically?
The molecule is a hydrophobic polyester formed by self-condensation of a hydroxylated C18 fatty acid, leaving ester linkages and residual acid functionality that support pigment wetting and water-in-oil emulsification. It is most useful in oil phases, color cosmetics, balms, and low-water systems, and it is more sensitive to strong hydrolysis conditions than to normal cosmetic pH ranges.
