Addition Order & Process
Procedure: Dissolve sodium carbonate in water. Add sodium LAS and AE-7; mix 15 minutes. Add SXS, then preservative, fragrance, and dye sequentially. QS with water.
Formulation Notes
The medium tier introduces a nonionic alcohol ethoxylate (AE) co-surfactant and preservative system. The LAS-to-nonionic ratio of approximately 2:1 follows industry practice for synergistic blends.
Formulation FC-10.1-M — Medium Multi-Purpose Cleaner (Liquid)
Specification: pH 8.5 ± 0.3; viscosity 150–400 mPa·s (Brookfield RVT, 25°C); active matter 9.2% ± 0.3%. The addition of AE-7 extends cleaning to greasy kitchen soils, while SXS maintains a single-phase liquid across 5–40°C storage. The preservative addresses microbial contamination of dilute surfactant solutions, particularly Pseudomonas species that metabolize LAS and produce off-odors within 4–6 weeks at 30°C.
