- "SMH-480" — a fat liquor for fatliquoring soft leathers of chrome, vegetable and mixed tanning methods;
- "SMH-600" - a fat liquor that gives the leathers special softness, evenly distributed both over the area and the thickness of the leathers, giving deep softness, tenderness and pleasant touch;
