‌Silicone Applications in Cosmetic Categories‌

‌‌1. Base Makeup (Foundation/Primer/BB Cream)‌

• ‌‌Pore Filling‌:
  Volatile silicones (e.g., D4/D6) rapidly evaporate, forming a smooth film on the skin surface to visually blur pores (filling depth >50 μm)1.
• ‌‌Anti-Caking‌:
  Silicones coat titanium dioxide/iron oxide pigments to prevent powder agglomeration, enhancing spreadability (spreading coefficient ↑35%)4.
• ‌‌Transfer Resistance‌:
  Cross-linked silicone elastomers (e.g., ‌Dimethicone Crosspolymer‌) create a mesh network to lock pigments and prevent fabric transfer7.

‌‌2. Mascara/Eyeliner‌

• ‌‌Waterproof & Smudge-Proof‌:
  ‌Trimethylsiloxysilicate‌ forms a film on lashes that resists washing off even after 1-hour underwater immersion6.
• ‌‌Fiber Fixation‌:
  High-viscosity dimethicone (350-100,000 cSt) bonds fibers for volumizing/lengthening effects (load-bearing capacity >200%)3.

‌‌3. Lip Products (Lipstick/Lip Gloss)‌

• ‌‌Finish Adjustment‌:
  • High-refractive-index phenyl silicones (RI 1.46-1.58) enhance mirror-like shine;
  • Matte formulas use porous silica spheres (e.g., ‌Silica Dimethyl Silylate‌) for light diffusion5.
• ‌‌Reduced Stickiness‌:
  Low-MW cyclic silicones (D5) replace mineral oil for featherweight feel and non-transfer (viscosity <5 mPa·s)2.

‌‌4. Setting Spray/Loose Powder‌

• ‌‌Film-Forming & Longevity‌:
  Silicone resins (e.g., ‌Trimethylsiloxysilicate‌) create breathable films extending wear by 6 hours7.
• ‌‌Oil Control & Mattifying‌:
  Hydrophobically modified silica (‌Silica Silylate‌) absorbs 220% of its weight in sebum4.
