While less toxic than petroleum-based oils, silicone oils pose ecological risks:

Persistence: Degrade slowly, lasting decades in soil/water.

Bioaccumulation: Low solubility leads to absorption by aquatic organisms.

Recycling Challenges: Complex purification processes increase costs.

Innovations like "cleavable silicones"—designed to break into harmless silica—are gaining traction. Regulatory bodies urge industries to adopt ISO 14000 standards for silicone waste management.
