Polyricinoleate ●
TL;DR. This ingredient is primarily a lipophilic emulsifier and co-emulsifier, especially useful for water-in-oil systems, anhydrous balms, and pigment-rich formulas. It also helps improve dispersion, texture, and cushion in oil-based products.
What does Polyricinoleate do in a cosmetic formula?
This ingredient is primarily a lipophilic emulsifier and co-emulsifier, especially useful for water-in-oil systems, anhydrous balms, and pigment-rich formulas. It also helps improve dispersion, texture, and cushion in oil-based products.
Is Polyricinoleate clean?
It is generally well tolerated and has little clean-standard friction, with no major allergen or restricted-list profile in typical cosmetic use. Quality depends on control of residual free fatty acids, catalyst traces, and oxidation byproducts from processing.
Is Polyricinoleate sustainable?
This material is typically made from plant-derived fatty acids, often from castor oil, and its ester-rich structure is expected to be biodegradable. Its sustainability profile is stronger when the crop supply is responsibly managed and processing uses low-residue catalysts.
Is Polyricinoleate COSMOS-approved?
It can align with COSMOS-natural or COSMOS-organic principles when made from permitted natural-origin feedstocks using accepted esterification or polymerization chemistry. From a Green Chemistry view, it scores well on renewable sourcing and biodegradability, with the main caveat being catalyst choice and purification efficiency.
How does Polyricinoleate work chemically?
The molecule is an oligomeric fatty-acid ester with hydroxyl-bearing long chains, giving it strong oil compatibility and interfacial activity in low-HLB emulsification. It is generally stable across typical cosmetic pH ranges when protected from excessive heat and oxidation, and antioxidants may be used in oil-rich formulas to support freshness.
