INTRODUCTION

DENIE-SOAK ES-G is an alkaline protease enzyme concentrate designed to be diluted prior to being used to rehydrate hide after it has been preserved by salting and drying. The use of enzymatic soaking agents can reduce the soaking process time to 4 – 6 hours.
Dilution may be undertaken by the tannery or, more commonly, by third party formulators who may blend it with other active constituents.

TEMPERATURE and pH PROFILES

The performance of enzymatic leather processing products depends upon process conditions such as temperature, pH, time, nature of the substrate and enzyme concentration.
The nature of DENIE-SOAK ES-G means that it is effective at typical soaking temperature (approx. 25°C) even though its optimum temperature for activity is approximately 40° - 50°C.
DENIE-SOAK ES-G is effective over a wide pH range (7.0 - 10.0) with optimum activity about pH 9.5.

Due to the type of enzyme and its versatility, DENIE-SOAK ES-G can be considered as the enzyme constituent of products used in other leather processing stages such as bating.

DIRECTIONS FOR USE

DENIE-SOAK ES-G has a high enzyme activity level and should not be used directly in leather processing stages in its neat form. The product should be diluted or used as a constituent of a soaking preparation prior to use. The dosage level of a dilution or preparation should be equivalent to using 0.0015% to 0.0030%
DENIE-SOAK ES-G on weight of hide.

Note:Protease enzyme based products (including DENIE-SOAK ES-G) must never be used on putrefied materials.

Variations in hide and local conditions can affect the performance of leather processing chemicals. DENYKEM recommend that small scale tests are carried out under local conditions before using products in full scale production. This will avoid any overdosing and any damage that may result from it. This is especially important where poor quality or badly preserved hides are being processed.
