BRB SG 116 – Cyclopentasiloxane (and) Dimethicone/Vinyl Dimethicone Crosspolymer

BRB SG 116 is a premium silicone elastomer gel widely used in skincare, cosmetic, and personal care formulations. This advanced skincare chemical is designed to deliver a silky-smooth texture, soft-focus effect, lightweight feel, and elegant matte finish in beauty and cosmetic products.

In skincare formulations, BRB SG 116 helps improve product spreadability and sensory performance while reducing greasy after-feel. It creates a soft, velvety skin feel that enhances the application experience of creams, serums, moisturizers, sunscreens, and facial products.

BRB SG 116 is especially popular in makeup primers, BB creams, foundations, and cosmetic formulations where a smooth, blurred, and matte appearance is desired. It helps minimize the appearance of uneven texture while improving formulation aesthetics and skin feel.

Its lightweight silicone elastomer structure makes it suitable for modern cosmetic products requiring luxurious texture and advanced sensory performance.

• Benefits & Uses (Short):
  • Thickens oil and silicone phases in formulations
  • Gives soft, silky, powdery skin feel
  • Improves spreadability of creams, serums, foundations
  • Adds mattifying and non-greasy finish
  • Enhances water resistance and product stability
  • Used in makeup, sunscreens, hair care, antiperspirants, skincare
• How It Works (Short):
  • Works as a crosslinked silicone elastomer network suspended in volatile silicone (cyclopentasiloxane)
  • Forms a smooth gel matrix that traps oils and active ingredients, increasing viscosity
  • Creates a “soft-focus” effect by scattering light on skin, reducing shine
  • Improves slip by reducing friction between skin and formulation
  • Volatile carrier evaporates after application, leaving a smooth elastomer film
  • This film provides long-lasting silky feel, water resistance, and better pigment dispersion in makeup systems
