DOWSIL SM5571 is a food-grade silicone-silica composite defoamer developed in Japan, meeting JECFA standards. It comes as a white liquid (1,000-1,500 mPa·s viscosity), maintains stable activity at pH 5-10, and has dynamic surface tension as low as 24 dyn/cm—collapsing micron-level foam within 5 minutes with 8+ hours of suppression. With 35% active content, it holds certifications from FDA 21 CFR 175.300 and GB 9685-2016, making it ideal for high-protein food processing and beverage production while cutting mineral oil defoamer usage by 20%.
Dual Food-Grade Certifications: Complies with JECFA and FDA standards, containing no heavy metals or plasticizers, ensuring safety for food-related applications.
Fast Foam Elimination: Nano siloxane particles reduce surface tension to eliminate foam quickly, addressing foam issues in time-sensitive food processing steps.
High-Temperature & pH Resistance: Maintains stable performance under 120°C sterilization conditions and across pH 3-12 environments, adapting to diverse food processing scenarios.
Dairy Processing: Controls foam in yogurt and cheese fermentation processes, with a recommended dosage of 0.05%-0.1%, ensuring smooth fermentation and product quality.
Beverage Production: Eliminates foam in carbonated drink filling lines, reducing filling errors and improving production line efficiency.
Condiment Manufacturing: Enhances uniformity in the production of soy sauce and oyster sauce, preventing foam-induced inconsistencies in texture and concentration.
