IOTA 20577 Diethyltetramethyldisiloxane (CAS: 2295-17-2) is a colorless, odorless, and transparent silicone fluid with distinctive physical properties. It exhibits a low viscosity of 0.97 cP at 25 °C and a density ranging between 0.813–0.818 g/cm³ at the same temperature. Its exceptionally low pour point of -120 °C makes it highly suitable for applications requiring stability at extremely low temperatures.

This organosilicon compound is widely used in the personal care industry. It serves as a key ingredient in antiperspirants and deodorants, where it improves spreadability and delivers a smooth, non-greasy skin feel. It is also incorporated into skin lotions, sunscreens, and various cosmetic formulations to enhance texture, provide water resistance, and facilitate even distribution of active ingredients.

Beyond personal care, IOTA 20577 is valuable in industrial and laboratory settings. Its low pour point and thermal stability make it an excellent heat transfer fluid for closed-system low-temperature oil baths, ensuring reliable performance in processes requiring precise temperature control.

In summary, IOTA 20577 Diethyltetramethyldisiloxane is a versatile silicone offering unique benefits in both cosmetic formulations and specialized technical applications.
