Product Description

 leather Soaking enzyme


Product characteristics

² Finished enzyme used directly

² Reduce soaking time, save cost

² Improve leather hydrate quality, make leather backwater fresh, and increase storage time

² Remove impurity in furs thoroughly, improve scrubbing effects.




GRM403 is a bacterial alkaline protease concentrated powder, can diluted to finished enzymes with different concentration and different requirements. The product is used for soaking leather (hide), hydrate leather, to make fresh skin backwater; used for salt dry skin or salt wet skin, to avoid leather rot during storage. This soaking enzyme can save soaking time about 4-6 hours, save energy. 


Temperature & PH range


When using leather enzyme, product properties are based on technologies, like PH value, temperature, time, natural characteristics of substrate and enzyme activity, and so on. All the factors have influence on product using effects.


GRM403 function temperature is same as typical soaking process (about 25ºC), even the enzyme optimum activity effected temperature is 40-50ºC.


GR-M403 has a wide function PH range, which is 7.0-10.0, and optimum is 9.5.


Due to versatility of enzyme itself, GR-M403 can be used in other leather processes, like soften process.


Usage guidelines


GR-M403 can be used directly or mixed using with other auxiliaries as a pre-soak material.

Recommend dosage: 0.28%-0.5% (calculate by leather weight)

GR-M403 is limited to be used in rot leather.

Leather diversity and different resources, local production operating environment all can affect leather enzyme using effects, recommend to do small testing under same production operating environment, then do mass production.This can avoid damage and influence to hide because of excessive or different process. Particularly to less quality leather, process technology and time must be more accurate.


Technical data (typical)


Appearance:      mixture of granules and powder. (Note: color maybe different with each batch, but will not affect product activity and using effects)

Active ingredients:  bacterial alkaline protease

Activity:    1000 LVU/g

Storage:  5-25 ºC dry room temperature (product should be sealed in occluded devices and avoid exposure to moisture and high humidity)

Shelf life:   shelf life is 6 months under correct storage condition. If stored in high temperature or high moisture for long time, should increase dosage to reach desired effects.


Health & safety


All enzymes and preparation products must be stored and used careful specially. More information, please refer to safety data instruction.


The data is just as guide data, changed based on different production conditions, production technology and effects. Please use the product according to specific requirements, meanwhile, recommend to do small testing, then use in mass production. Suggest to use after testing based on machine types, leather resource, water quality and user requirements. Our company do not response to any loss of leather caused by improper use.
