Tributoxyethyl Phosphate (TBEP)
Cas No. : 78-51-3
EINECS No.: 201-122-9
Molecular formula: C₁₈H₃₉O₇P
Molecular weight: 398.47
Basic Properties
Chemical Classification
Organophosphate ester (C₁₈H₃₉O₇P)
Solubility
Soluble in: Most organic solvents (alcohols, ketones, esters), mineral oils. Partially soluble in: Water (~0.1% at 20°C). Insoluble in: Aliphatic hydrocarbons.
Functional Features
- Plasticizer and flame retardant
- Leveling agent and gloss enhancer
Key Advantages
- Excellent compatibility with floor polish formulations
- Provides durable film formation
- Enhances scratch resistance
Limitations
- Moderate flame retardant efficiency
- Higher viscosity than common plasticizers
Functional Mechanism in Floor Polishes
TBEP works through multiple mechanisms:
Plasticization: Softens polymer matrix for better film formation
Flame Retardancy: Releases phosphoric acid under heat
Surface Modification:
- Improves leveling and flow-out
- Enhances gloss and surface smoothness
- Reduces whitening and cracking
