Ethyl silicone oil, known for its low viscosity and low surface tension, serves as a multifunctional additive in textiles, leather, plastics, and specialty chemicals. The ethyl groups enhance flowability and film formation at low temperatures.

In textiles, it functions as a softening and hydrophilic agent; in leather, as a gloss enhancer and tactile modifier. In plastics, it improves mold release and surface smoothness. In personal care, it adds a silky texture to lotions and creams. Ethyl silicone oil also serves as a carrier or processing aid in complex industrial formulations, contributing to system uniformity and stability.
