Green Luxury: How Mushroom Chitosan is Redefining Bio-Leather for the Eco-Conscious Market
1. What is Mushroom Chitosan?
Mushroom chitosan is a natural biopolymer extracted from the cell walls of fungi. It’s derived from chitin, a structural component that gives mushrooms their rigidity and form.
Origin and Abundance
- Chitin is the second most abundant natural polysaccharide in nature, after cellulose.
- Most fungi contain 5%-7% chitin in their cell walls.
- Chitin is also found in the exoskeletons of crustaceans (crabs, shrimp, lobsters) and insects.
Pronunciation Guide
- Chitin: Pronounced “KITE-in” (emphasis on “kite”)
- Deacetylation: Pronounced “dee-a-SETTLE-ay-shun” (emphasis on “dee”)
- Acetyl: Pronounced “A-see-tl” (emphasis on “see”)
Chemical Structure and Properties
Chitosan is obtained through a process called deacetylation of chitin. This involves:
- Removing acetyl groups (CH3OH) from the chitin molecule
- Creating a polymer with free amine groups (NH2)
This chemical transformation gives chitosan its positive charge, differentiating it from its parent compound, chitin.
-
- Solubility: Unlike chitin, chitosan is soluble in acidic to neutral solutions, making it more versatile for various applications. Our food grade mushroom chitosan oligosaccharide is soluble in water at any pH. It is bactericidal at pH 6.4 and below. To purchase wholesale, click HERE

- Chitosan Powder: This is the most straightforward form of mushroom chitosan used in bio-leather production. The powder can be dissolved in a solvent and then applied to the bio-leather substrate. This application can help in the cross-linking of fibers, improving durability, and imparting antimicrobial properties.
- Dosage: Typically, chitosan powder concentration ranges from 1% to 5% by weight relative to the material it’s being applied to.
- Application: The powder is often dissolved in a mild acidic solution (like acetic acid) to ensure it fully dissolves before application. It can then be applied through spraying or immersion methods during the tanning or post-tanning stages.
- Chitosan Solution: Mushroom chitosan powder can be dissolved in aqueous or organic solvents to form a chitosan solution. This solution can be used in the tanning process or as a finishing spray on bio-leather to enhance its mechanical properties, water resistance, and to provide an antimicrobial surface.
- Dosage: Concentrations in a solution can vary between 0.5% to 3%. The precise concentration depends on the desired strength and thickness of the bio-leather.
- Application: Applied through dipping, spraying, or padding. The pH of the solution should be adjusted (usually between 4.0 and 6.0) to ensure stability and effectiveness of the chitosan.
- Chitosan Films and Coatings: Chitosan can be processed into thin films and coatings that can be directly applied onto the surface of bio-leather. These films can provide a protective barrier against moisture, microbial growth, and physical abrasion.
- Dosage: Film thickness can vary but is generally in the range of a few microns to about 100 microns. The concentration of chitosan in the coating solution might be higher, typically around 1% to 2%.
- Application: The film or coating can be applied by brushing, spraying, or using a curtain coating technique to ensure an even layer.
- Chitosan Nanoparticles: For a more targeted and efficient application, chitosan can be engineered into nanoparticles. These nanoparticles can deeply penetrate the bio-leather, offering improved performance in terms of strength, flexibility, and resistance to environmental factors.
- Dosage: Due to their high efficiency and surface area, lower concentrations such as 0.1% to 1% can be effective.
- Application: These can be incorporated into bio-leather via spraying or immersion methods, where they can penetrate deeply and distribute uniformly throughout the material.
- Chitosan Fibers: Although less common, chitosan can also be spun into fibers that can be woven or integrated into the structure of bio-leather, reinforcing the material from within or providing a unique texture to the surface.
- Dosage: Not precisely defined as it depends on the desired properties of the end product. Chitosan fibers can be blended with other fibers at various ratios depending on the application.
- Application: These fibers can be woven into the fabric or used as a non-woven mat that forms part of the bio-leather structure.
Mushroom chitosan offers unique benefits and can be utilized based on the specific requirements of the bio-leather being produced, such as the desired physical properties, application methods, and environmental considerations. For each application, the processing conditions such as temperature, pH, and time are critical and must be optimized based on the specific type of bio-leather and the desired properties. Experimentation and testing are essential to determine the optimal conditions for each specific case. Additionally, it’s important to ensure that all components used are compatible with vegetal chitosan to maintain the integrity and performance of the bio-leather.
5. Considering solubility, the optimal type of chitosan for various bio-leather applications can vary among acid-soluble chitosan, chitosan hydrochloride, chitosan oligosaccharide, and carboxymethyl chitosan.

6. Considering viscosity, which type of acid-soluble chitosan is optimal for different bio-leather applications?
When choosing the optimal type of acid-soluble chitosan for bio-leather applications based on different viscosity ranges (20-100 cps, 100-500 cps, 500-1000 cps), it’s important to consider how the viscosity affects the processing and final properties of the bio-leather. Here’s how different viscosities can be suited for specific applications:
- Low Viscosity (20-100 cps):
- Ideal Application: Finishing and Softening Treatments
- Explanation: Lower viscosity chitosan is excellent for finishing treatments where a lighter, more fluid application is required. It can easily penetrate the bio-leather, enhancing softness and flexibility without significantly altering the bulk properties or feel of the leather.
- Medium Viscosity (100-500 cps):
- Ideal Application: Intermediate Coatings and Moisture Barriers
- Explanation: This viscosity range is suitable for applications that require a more substantial coating, yet still need good penetration into the leather. It’s ideal for intermediate treatments that provide additional moisture resistance or act as a primer for further finishing layers. This range helps to improve durability and maintain the natural look and feel of the leather.
- High Viscosity (500-1000 cps):
- Ideal Application: Structural Enhancements and Protective Top Coats
- Explanation: Higher viscosity chitosan is beneficial for creating protective top coats or for use in treatments that require a thicker layer, which contributes to the overall structural integrity of the leather. These applications are critical in areas requiring enhanced wear resistance, such as in the production of footwear or high-traffic upholstery.
Each viscosity level of acid-soluble chitosan caters to a different phase of the leather treatment process, from deep penetration and softening to providing robust protective layers. Adjusting the molecular weight of the chitosan and its concentration in the treatment solutions can control the viscosity, thus allowing for precise application tailored to the needs of the bio-leather product.
