Formulation Notes
Industrial laundry operations process substantially higher soil loads than domestic washing, often requiring disinfection of textiles from healthcare, hospitality, and food-service sectors. Base detergents for institutional use are typically highly alkaline, bleach-free concentrates containing a full builder system (phosphate or zeolite with polymer cobuilder), fluorescent whitening agents (FWAs), and enzymes . The formulation below targets continuous-batch washers (CBW) with counterflow rinsing, where high active matter and controlled foam are essential for mechanical soil transport.
Procedure. Premix the LAS and alcohol ethoxylate in a separate vessel; this liquid surfactant blend is sprayed onto the powder base in a ribbon or ploughshare mixer. Dry-blend zeolite, sodium carbonate, metasilicate, and sodium sulfate. Add the surfactant blend with continuous mixing, then sequentially incorporate sodium polycarboxylate, CMC, enzyme granules, and optical brightener. Enzyme granules must be non-dusting stabilized forms to prevent sensitization. Final powder moisture: 6-9% .
Specifications. pH (1% solution, 25°C): 11.0 ± 0.3; active matter: 30% ± 1.5%; bulk density: 550 ± 50 g/L; dust content: < 0.5%. Enzyme activity retained ≥ 90% after 12 weeks at 30°C.
Application. Dose at 3-5 g/L wash liquor (soft water) to 5-8 g/L (hard water > 250 ppm CaCO₃). Suitable for CBW systems at 60-85°C main wash. Not compatible with chlorine bleach; use oxygen bleach (sodium percarbonate) if bleaching is required .
GHS Classification. Skin Irritation Category 2 (H315); Eye Damage Category 1 (H318); Signal word: DANGER. May cause sensitization by skin contact (enzyme proteins). Required PPE: chemical-resistant gloves, dust mask (FFP2 or N95) during powder handling, eye protection.
