Chemical & Physical Data:
Compact surfactant , free of APEO
pH:11.0 -14.0 (1%)
DOWELLAN SPH has good wetting and grease-emulsifying abilities; it can be used at pH between 6 and 13. It dissolves the dirt effectively in keeping pH of the float stable. It is stable to hard water. It is compatible with DOWELLZYM range of enzymes.
DOWELLAN SPH is used in soaking, enzymatic unhairing, enzyme pasting, lime pasting and liming to accelerate water absorption and improve penetration of other chemicals.
Application examples (based on the weight of wet-salted hides and skins):
1.The dosage of DOWELLAN SPH depends on the temperature, time and the condition of the raw hides and skins.
2.Soaking: rapid soaking (30℃-32℃，4-6h) 0.4%-0.6%.
normal soaking (20℃-25℃，1-2days) 0.2%-0.4%.
3.Using DOWELLAN SPH in soaking process together with DOWELLIT bactericide will accelerate soaking with good preserving effect.
4.Enzyme pasting and lime pasting: 3－6g/L.
5.Liming: 0.1%－0.2% DOWELLAN SPH improves the penetration of liming auxiliaries and helps to loosen hair roots.
