Neutral Protease (Industrial Grade Enzyme Preparation)
Neutral Protease is an industrial-grade solid enzyme preparation with an activity of 60,000 U/g. It is designed to function efficiently under neutral to mildly acidic or alkaline conditions and is widely used in leather processing and cosmetic-related applications. The enzyme works by hydrolyzing protein macromolecules into peptides and amino acids, enabling controlled protein degradation with mild reaction conditions, high efficiency, and good process adaptability.
This product appears as a light yellow to light brown powder with a slight fermentation odor. It is free from abnormal odors, caking, or moisture absorption, ensuring stable performance during storage and use. Due to its balanced activity profile, Neutral Protease is suitable for a wide range of industrial formulations and processing workflows.
Main Application Areas
Leather Industry
Neutral Protease is suitable for multiple leather processing steps, including depilation and softening processes for various types of hides and skins. It helps remove non-structural proteins, loosens collagen fiber structures, and reduces unnecessary residues within the leather matrix. By eliminating impurities and surface contaminants, the enzyme improves cleanliness and enhances the softness, fullness, and overall hand feel of finished leather. Its use contributes to improved leather quality, smoother surfaces, and better process control.
Cosmetic-Related Applications
In cosmetic formulations, Neutral Protease can assist in the controlled breakdown of keratin and protein-based components. It helps soften the skin, supports the removal of aged keratin, and promotes normal skin renewal and metabolism. As a functional additive, it can contribute to gentle exfoliation effects and improved skin smoothness when applied appropriately within formulation systems.
Functional Benefits
The enzyme helps improve leather softness and surface cleanliness, supports efficient processing under moderate conditions, and promotes keratin renewal and metabolic activity in cosmetic-related uses. Its mild action profile allows effective performance while maintaining material integrity.
