Q1: What is the primary function of DOWSIL FZ-2222 Silicone Fluid in personal care formulations?
A: DOWSIL FZ-2222 is a low-viscosity, volatile silicone fluid designed to provide lightweight sensory benefits—such as silky slip, reduced tackiness, and improved spreadability—in leave-on and rinse-off personal care products including lotions, creams, shampoos, and conditioners.
Q2: Is DOWSIL FZ-2222 compatible with common surfactant systems and emulsifiers used in cleansing products?
A: Yes, DOWSIL FZ-2222 exhibits good compatibility with anionic, nonionic, and amphoteric surfactants, as well as typical oil-in-water and water-in-oil emulsifiers. It remains stable under standard formulation pH and temperature conditions encountered during manufacturing and storage.
Q3: How does DOWSIL FZ-2222 differ from other volatile silicones like D5 or D4?
A: Unlike cyclic siloxanes such as D4 or D5, DOWSIL FZ-2222 is a linear, low-molecular-weight polydimethylsiloxane (PDMS) fluid with defined end-group chemistry. It offers comparable volatility and sensory performance while aligning with evolving industry preferences for linear alternatives in certain regulatory and sustainability contexts.
Q4: What is the typical dosage range for DOWSIL FZ-2222 in cosmetic formulations?
A: Dosage depends on the desired sensory effect and product type, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—in both rinse-off and leave-on applications.
