Description

Silicone elastomer is the compound of macromolecule silicone elastomer in Cyclopentasiloxane.

Cosmetics Applications

Suitable for preparing W/O, O/W emulsion and non-water products:
Skin care, color cosmetics, deodorants, antiperspirants

Features

  • Compatible with a variety of lipophilic active ingredients such as fragrances, sunscreens, vitamins, and vitamin derivatives
  • Clear to slightly translucent crosslinked silicone elastomer gel
  • Easy to formulate
  • Acts as a thickening agent for water-in-oil and water-in-silicone formulations and silicone fluids
  • Slight sebum absorption
  • Provides dry smoothness and a light silky skin feel non-greasy
  • Enhances the aesthetics of volatile silicones

 Application Method

Silicone Elastomer Emulsion can be mixed with water. Add into system of emulsion formulation directly is better for its dispersibility. It is recommended to add cyclomethicone and skin-protective grease with low viscosity into the formulations  to get silkier and velour skin feel.

Mixed the system of formulation with stirring or shearing device.

The common usage level of BT-9268 is 0.5-6.0% in hair care formulations, 10-20% in skin care or sun care formulations, and 30-70% in color cosmetics products.It is also recommended to carry out preliminary tests to determine the optimum quantity for particular application.

Condensation Cure RTVs:

Probably the most widely used cure chemistry in RTVs is that of condensation cure. One of the key features of condensation cure is that of being hard to inhibit by most pollutants in the application environment.

These systems consist of one (RTV-1) or two (RTV-2) components. In the case of RTV-1, the product will cure upon exposure to moisture in the air as it is applied out of its package. In the case of RTV-2, the curable composition is formed by mixing two components during application.

RTV condensation cure systems are prepared from silanol-terminated PDMS, crosslinker and catalyst; reinforcing fillers and pigments are common additives.

There are four major cure systems in use related to the nature of the crosslinker: acetoxy, alkoxy, amine and oxime. The corresponding split products are acetic acid, alcohol, amine and oxime, respectively. Common catalysts are organotin and organotitanate.

As mentioned above, the reaction is carried out in the presence of moisture with evolution of the corresponding split product to form siloxane bonds in a tri-dimensional network.
