Product Description
What Is Silicone L620?
Silicone L620 is a polydimethylsiloxane (PDMS) fluid that is frequently utilized in both industrial and personal care settings. It is a type of silicone oil that exhibits excellent emollient, conditioning, and antifoaming properties. In cosmetics, it provides a smooth, non-greasy feel to products and helps improve the spreadability of creams, lotions, and hair care formulations. In industrial uses, it serves as a lubricant and antifoam agent.
Preparation Method:
Silicone L620 is typically synthesized by the hydrolysis and condensation of dimethyldichlorosilane (DMDCS) in the presence of a catalyst (e.g., an acid or base). The reaction produces a polydimethylsiloxane polymer, which is then filtered, purified, and diluted to the desired viscosity and consistency. The final product is a colorless, odorless, and stable liquid that is soluble in a variety of solvents like toluene and acetone. Depending on the intended usage in industrial, personal care, or cosmetic applications, the precise formulation may change.
