Science
Mechanism of Action
IPDI/PEG-15 Soyamine Copolymer Dimer Dilinoleate operates primarily as a film-forming agent, establishing a continuous, protective film on the skin's surface. As a polymeric cationic conditioner-emollient, it actively enhances skin condition by imparting significant slip, lubricity, and emolliency. Its formulation as a water-soluble polyurethane provides conditioning and a desirable sheen, offering a silicone-like effect without the potential for accumulation.

Stability
This ingredient demonstrates broad pH stability, remaining effective across a wide range from pH 2 to 12. Its polyethylene glycol (PEG) components also contribute to a versatile spectrum of solubility and viscosity properties, ensuring formulation flexibility.
Safety
Safety Profile
While related 'dialkyl dimer dilinoleates' were concluded as safe for cosmetic use by CIR in 2003 and reaffirmed in 2018, specific data for the broader 'Dimer Dilinoleates' group, to which this ingredient belongs, is currently insufficient to justify a formal Scientific Literature Review as of February 2025. Polyethylene glycols (PEGs), integral to its structure, are generally well-tolerated by the skin and are not microbiologically sensitive.
