Formulation Notes
High-foaming, high-cling pre-wash formulation for dwell times of 5–10 minutes before contact washing.
Method: Hydrate xanthan gum in a portion of water at 60 °C with high-shear mixing. In main vessel, combine remaining water, SLES, CAPB, and cocamide DEA at 45 °C. Add sodium carbonate and EDTA. Incorporate xanthan gum slurry. Cool to 30 °C; add d-limonene (pre-emulsified if needed). Add preservative and colorant. Use dilution: 1:10 to 1:20 in foam cannon. Properties: pH 8.5–9.5, viscosity 3{,}000–6{,}000 cP, foam half-life ≥ 15 min (Ross–Miles). The alkaline builder (sodium carbonate) raises the pH sufficiently to hydrolyze organic soils — bug residue, pollen, road film — without reaching levels that would damage paint .
