Full Description

Phenyl Trimethicone (CAS 2116-84-9) is a phenyl-substituted polysiloxane (silicone) supplied as a clear fluid. It is used in cosmetic formulations as an emollient, antifoaming and antistatic agent, and as a viscosity modifier.

Frequently Asked Questions

Is phenyl trimethicone a silicone?

Yes. Phenyl trimethicone (CAS 2116-84-9) is a phenyl-substituted polysiloxane, i.e. a silicone fluid, supplied as a clear liquid. It is used in cosmetic formulations as an emollient, antifoaming and antistatic agent, and as a viscosity modifier.

Is phenyl trimethicone the same as dimethicone?

No. Both are silicones, but phenyl trimethicone carries phenyl substituents on the siloxane backbone, giving a higher refractive index and different optical and spread properties than dimethicone. They are distinct fluids selected for different formulation effects.

What is phenyl trimethicone used for in formulations?

It functions as a skin- and hair-conditioning emollient, an antifoam additive, an antistatic agent in hair-care products, and a viscosity modifier in cosmetic systems. It is supplied as a clear silicone fluid for personal-care formulating.

What is the chemical identity of phenyl trimethicone?

Phenyl trimethicone is a phenyl-substituted polysiloxane, CAS 2116-84-9, supplied as a clear silicone fluid and classified under HS code 3910.00. Request the CoA for the specific viscosity grade supplied.

What is the cost of bulk phenyl trimethicone?

Pricing depends on grade, viscosity, volume, and packaging. Request a bulk quote with your required quantity rather than relying on a list price, and we will return current pricing along with the CoA and SDS.
