Dow DOWSIL EG-1200 Silicone Gel – Frequently Asked Questions (FAQ)
Q1: What is the primary function of DOWSIL EG-1200 Silicone Gel in formulations?
A: DOWSIL EG-1200 is a soft, low-viscosity silicone gel designed to provide skin-feel enhancement, surface lubricity, and sensory modification in personal care and cosmetic products. It functions as a conditioning agent and delivery vehicle for active ingredients, improving spreadability and leaving a non-greasy, silky afterfeel.
Q2: Is DOWSIL EG-1200 compatible with common emulsification systems and preservatives?
A: Yes, DOWSIL EG-1200 demonstrates broad compatibility with oil-in-water and water-in-oil emulsifiers, including nonionic, anionic, and amphoteric surfactants. It is also stable in the presence of typical cosmetic preservative systems and does not significantly interfere with their efficacy when used at recommended levels.
Q3: How should DOWSIL EG-1200 be incorporated into a formulation?
A: It is typically added during the cool-down phase (below 45°C) of emulsion processing to preserve its integrity and ensure uniform dispersion. Pre-dilution with a compatible carrier oil or phase may aid incorporation in highly structured systems. Homogenization or gentle mixing is generally sufficient—high-shear processing is not required.
Q4: Does DOWSIL EG-1200 require special storage conditions?
A: Store in tightly sealed containers at room temperature (15–30°C), away from direct sunlight and sources of heat or moisture. Under these conditions, the product maintains stability and performance over its shelf life. Avoid prolonged exposure to freezing temperatures or elevated humidity.
