Science
Mechanism of Action
Functioning as an associative thickener, this ingredient binds water by balancing its water-loving and oil-loving characteristics. This dual affinity allows it to effectively control product viscosity and stabilize oil-in-water emulsions.

Safety Profile
The CIR has noted 'insufficient data' for this specific SMDI-based copolymer. While the CIR concluded many HDI polymers are safe provided no significant residual isocyanate monomers, this particular SMDI variant was not explicitly included in those findings.
