Pure Silicone Oil 500000 CSt

Our 500,000 cSt silicone fluid is a linear polydimethyl silicone fluid. This product is a highly viscous liquid or paste semi-solid, is essentially odorless, non-toxic, non-greasy, non-skin sensitizing, has soft comfortable, antioxidant, hydrophobic, and moisture-proof, anti-stick, and reduces surface tension. As a conditioning agent, it is often used in hair care products.
