Castor Oil/IPDI Copolymer
Ingredient Info
This is a synthetic polymer made by chemically combining castor oil with IPDI (isophorone diisocyanate). It functions as a film-former and texture enhancer in skincare products, helping to create a smooth, even application and improve how products feel and spread on the skin.
Benefits
- Creates a smooth, even texture in formulations
- Helps products spread more easily across skin
- Provides film-forming properties for product adherence
Potential concerns
- Limited safety data available for this specific polymer
- Potential irritation in sensitive individuals (as with most synthetic polymers)
- IPDI is a reactive chemical; residual unreacted material could theoretically cause sensitivity, though this is unlikely in properly formulated products
Science: Limited peer-reviewed data available for this ingredient. Safety relies on manufacturer compliance with cosmetic regulations and proper synthesis to minimize unreacted isocyanate residues. General polymer safety in cosmetics is well-established, but this specific copolymer lacks independent published studies.
