Castor Oil/Ipdi Copolymer

What Castor Oil/Ipdi Copolymer is & what it does

Castor Oil/IPDI Copolymer is a synthetic polymer made by reacting castor oil with isophorone diisocyanate (IPDI). It is used as a film former and texture-enhancing agent that can help a sunscreen or cosmetic layer evenly on the skin and improve water resistance and wear. The castor oil portion contributes conditioning fatty components while the polymer network adds durability to the film.

What does Castor Oil/Ipdi Copolymer do in skincare?

Castor Oil/IPDI Copolymer acts as a film former and texture agent. It helps a sunscreen or cosmetic spread evenly and form a flexible film on the skin, which can improve wear and water resistance.

Is Castor Oil/Ipdi Copolymer safe?

Castor Oil/IPDI Copolymer is used in cosmetics as a film-forming polymer and is generally considered suitable for topical use in finished products. Sensitivities can vary between individuals, so a patch test is reasonable if you have reactive skin.

Is Castor Oil/Ipdi Copolymer natural or synthetic?

Castor Oil/IPDI Copolymer is synthetic. It is created by reacting castor oil, a plant oil, with isophorone diisocyanate to build a polymer, so the finished ingredient is a manufactured material that includes a plant-derived component.
