About Distearyl Diphosphite

Distearyl penataerythriol disphosphate + TIPA is frequently found in personal care products. It is a combination of two fatty alcohols, stearyl alcohol and pentaerythritol, that act as emulsifiers, or agents that assist water-insoluble and oil-insoluble molecules to mix. When combined with other substances, it also functions as a surfactant and conditioning agent that aids in the creation of a stable emulsion. Distearyl penataerythriol disphosphate + TIPA is an organic substance functions as an emulsifier and surfactant, lowering the surface tension between two immiscible liquids. Additionally, it aids in the prevention of product separation and increases the solubility of other constituents in a formulation

Effective Polymer Stabilization

Distearyl Diphosphite enhances the thermal and color stability of polymers, particularly PVC, polypropylene, and polyethylene. It acts as a secondary antioxidant, protecting materials from heat and processing stresses, which ultimately extends the service life and maintains the appearance of finished polymeric products.

Safe and Reliable Handling

This phosphite ester is recognized for its low toxicity profile and does not pose significant environmental hazards. Standard safety precautions are sufficient during handling. It is best stored in a cool, dry location away from strong oxidizers to preserve its stability and functional properties throughout its 24-month shelf life.

FAQ's of Distearyl Diphosphite:
