Science
Mechanism of Action
In formulations, Disteareth-75 IPDI functions primarily as an emulsifier, facilitating the homogeneous dispersion of immiscible phases such as oils and water. Concurrently, it acts as a rheology modifier, allowing for precise adjustment of product thickness and flow properties, thereby enhancing overall product stability and sensorial experience.

Stability
This ingredient maintains stability under typical environmental conditions, though exposure to extreme temperatures and direct sunlight should be minimized to preserve its efficacy. While it produces cloudy dispersions when solely combined with plain water, it demonstrates excellent functionality in aqueous surfactant systems, forming clear, viscous solutions essential for many formulations.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has classified Disteareth-75 IPDI with 'insufficient data' for a full safety assessment. No specific maximum concentration or FDA bans have been identified, though the EWG indicates its safety score may be elevated in inhalable product forms or if potential contamination from toxic impurities exists. It is important to distinguish Disteareth-75 IPDI from its raw monomer, Isophorone diisocyanate (IPDI), which is a known irritant and toxic by inhalation and skin absorption; the finished ingredient does not exhibit these monomer-specific characteristics.
