DOWSIL SH 5500 is a food-grade polysiloxane-silica composite defoamer made for high-foam food industry systems. It comes as a milky liquid, stays actively stable at pH 3-10, has dynamic surface tension down to 24 dyn/cm, quickly eliminates micron foam (8+ hours suppression), and holds FDA 21 CFR 175.300 and EU 10/2011 certifications. Ideal for dairy and sauces, it cuts mineral oil defoamer use by 25% while boosting production efficiency.
Nano-Scale Defoaming: Siloxane-silica particles break foam in 3 minutes, fitting high-shear fermentation tanks in food production.
Tough Condition Resistance: Endures sterilization temps (≤120°C) and pH 3-10 environments without performance loss.
Food-Grade Compliance: APEO-free and heavy metal-free, meeting FDA, EU, and China GB 2760 standards for food safety.
Extended Shelf Life: Maintains 540-day stability (no stratification) at 4-30°C—even when diluted 1:10.
Dairy Processing: Manages foam in yogurt and cheese fermentation processes, with a dosage of 0.05%-0.1%.
Beverage Production: Lowers filling errors in carbonated drink production lines for smoother operation.
Condiment Industry: Improves uniformity in the production of soy sauce and various sauces.
Food Packaging: Prevents oil oxidation during the filling of edible oils, preserving product quality.
