This enzyme is a concentrated liquid alkaline protease derived from strain fermentation of Bacillus subtilis by advanced biotechnology, which is especially suited for degradation of non-collage-nous hide components during bating process. Technical Index Appearance: light brown to brown liquid. pH value: 5.5-6.5 Gravity: 1.00-1.10 g/ml. Solubility:complete soluble in water. Product Features 1、The adaptive temperature range is wide, with good performance between 20-65℃, and the optimal operation temperature is 86℃. 2、Wide pH applicable range. At each pH 7.0-11.0 all have good performance. 3、Reduce the thickness with a significant area increase. 4、Make the leather softer, surface clean and smooth. 5、High concentrated feature provides easier re-formulation . Application Guidelines 1、Dose the enzyme according to different processes and raw materials. In order to prevent damage caused by overdos-ing the enzyme, it is strongly recommended to evaluate enzyme in small scale (on all hides and skins on which it will be applied), to determine the product dosage for bulk processing. 2、 Application Processes Dosage：0.0075%-0.01% Temperature:20–65℃ pH value:7.0–11.0 Treatment Time：10-25min. 3、Package and Storage Packages adopt PE plastic drum of which the packing specifications have:25kg, 220kg, 1100kg. Storing in temperature lower than 25℃ under sunlight prevention and dry environment will prolong the shelf life. Packing For Liquid enzyme: PE barrel,Spec:30kg, 225kg, 1125kg. Solid enzyme: 1.Inner packing is PE bags, external is paper drum. Spec:25kg, 50kg. 2.Paper-plastic laminating bags,Spec:20kg. Storage Enzyme is a kind of proteins of which the activity will be affected by high temperature and strong light. Therefore it shall be stored at 4-25℃ dry and ventilated place. Insolation and drench must be avoided. Shelf life Under suitable storage conditions, the liquid form enzyme can maintain activity at least 6 months, and the solid form enzyme can maintain activity at least 12 months. Expiration and or unsuitable storage conditions including high temperature will cause dosage increase. Transportation Enzyme is non-hazardous chemicals, which can be shipped as normal. Mixing and shipping together with hazardous and poisonous chemicals is prohibited. Avoid the direct sunshine and rain. Avoid stress, load and unload lightly. Attention Enzymes are proteins that direct contact will stimulate the skin, eyes or mucous membrane. If there is such a problem, immediately rinse thoroughly with warm water affected area for 15 minutes. If you still feel unwell, please at once see a doctor.
