LK-SIL 100 D(5)
INCI: Dimethicone
Introduction:
LK-SIL 100 D(5) is a low-viscosity Polydimethylsiloxane (PDMS) fluid with a viscosity of 5 cSt, engineered for use in high-performance personal care formulations. As a clear, non-volatile silicone fluid, it offers outstanding spreadability, lubricity, and long-lasting conditioning benefits. Unlike volatile silicones, LK-SIL 100 D(5) remains on the skin or hair surface longer, delivering a soft, smooth, and moisturized feel.
Polydimethylsiloxane (PDMS) 5 cSt can be a good alternative to cyclic silicones (like Cyclopentasiloxane or Cyclohexasiloxane) in certain applications, especially where regulatory restrictions or concerns about cyclic siloxanes (D4, D5, and D6) exist.
Manufactured to cosmetic-grade specifications, LK-SIL 100 D(5) is ideal for brands seeking stable, safe, and sensory-enhancing ingredients for skin and hair formulations.
