Formulation Notes
Mild, pH-buffered cleaner with conditioning oils to preserve leather finish and suppleness.
Method: Dissolve sodium citrate in water. Add sodium lauroyl sarcosinate. Add glycerin, MCT oil, and aloe extract. Add citric acid to adjust pH to 5.0–6.0. Add preservative. Properties: pH 5.2–5.8, milky emulsion. The citrate buffer resists pH drift during storage and application, maintaining the mildly acidic environment that matches the natural pH of finished leather (typically 4.5–5.5). Sodium lauroyl sarcosinate was selected over SLES because it is significantly milder to protein-based finishes while still providing adequate foaming and soil removal .
