Q1: What is the primary function of XIAMETER PMX-1401 in personal care formulations?
A: XIAMETER PMX-1401 is a low-viscosity, volatile silicone fluid designed to provide elegant skin feel, rapid spreading, and non-greasy dry-down—commonly used as a carrier or sensory enhancer in leave-on and rinse-off products such as lotions, sunscreens, and hair conditioners.
Q2: Is PMX-1401 compatible with common surfactant systems and emulsifiers?
A: Yes, PMX-1401 exhibits broad compatibility with anionic, nonionic, and amphoteric surfactants, as well as typical oil-in-water and water-in-oil emulsifiers. It is often incorporated into stable emulsions without requiring high-shear processing or specialized pre-treatment.
Q3: How does PMX-1401 differ from other volatile silicones like D4 or D5?
A: Unlike cyclic siloxanes (e.g., D4, D5), PMX-1401 is a linear, low-molecular-weight polydimethylsiloxane with controlled volatility and excellent biodegradability profile. It offers comparable sensory performance while aligning with evolving industry preferences for non-cyclic alternatives in consumer-facing applications.
Q4: Can PMX-1401 be used in rinse-off hair care products?
A: Yes—it is widely used in shampoos and conditioning rinses to improve combability, reduce static, and enhance shine. Its volatility ensures minimal residue after rinsing, supporting clean-rinse claims and compatibility with sulfate-free systems.
