Dimethiconol

Dimethiconol (CAS 31692-79-2) is a hydroxyl-terminated polydimethylsiloxane polymer, commercially available under trade names including PS 340, PS 344.5, PS 347.5, PRX 413, and 48V175000. It carries no assigned E-code. The polymer is classified within the broader silicone fluids family and falls under the Polymers and Resins category.

In personal care formulations, dimethiconol deposits a conditioning film on hair and skin surfaces, reducing friction and improving combability without occlusive buildup. In coatings and sealant systems, its hydroxyl functionality enables reactive incorporation into silicone networks, contributing to surface slip, release properties, and substrate wetting control across textile, leather, and automotive applications.

Dimethiconol is subject to REACH registration requirements for EU market supply and should be handled in accordance with applicable SDS documentation. It is available in multiple viscosity grades to suit specific formulation targets. Packaging formats vary by supplier and order volume; consult your account manager for available configurations.
