Natural protection, built into your product.
Chitotec® additives are based on chitosan, a natural biopolymer from crab and shrimp shells, produced in Germany with patented technology. Three product lines for polymers, water-based and oil-based products protect against bacteria, fungi and viruses, without changing how your product looks, smells or performs.
What Is Chitosan?
Chitosan is a natural biopolymer made from chitin, the material that forms the shells of crabs and shrimp. It is biodegradable and has natural antimicrobial properties.
We source crab and shrimp shells from the Persian Gulf and extract the chitosan at our facility in Germany, in a carefully controlled process based on German patented technology.
How it works: chitosan's molecular structure disrupts the cell walls of microbes and stops them from growing. It is particularly effective against gram-negative bacteria, the ones that cause bad odors and can contribute to skin irritation.
Chitotec® vs. silver & nano additives
| Chitotec® | Silver / nano-based | |
|---|---|---|
| Origin | Natural biopolymer | Metal-based |
| Biodegradable | Yes | No |
| Raw material cost | Lower than silver | Higher |
| Durability under UV | Up to 3× longer* | Baseline |
| Look & smell | Colorless, odorless | Can discolor |
* Chitosan encapsulated in herbal oil complexes, compared with nano-based alternatives, especially under UV or harsh conditions.
Why choose Chitotec®
The Chitotec® Products
Three versatile products, compatible with polymers, water and oil. Choose the one that fits your manufacturing process.
Chitotec Polymer®
A bio-based additive that combines chitosan with polymer technology. Added during masterbatch production, it makes polymers antimicrobial and biodegradable.
- Antimicrobial and antiviral
- Biodegradable, can be compostable
- Keeps the polymer's original strength, durability and flexibility
- Lower raw material cost than silver
Chitotec Aqua®
A fully transparent liquid that dissolves easily in water and in any pH-neutral product. Kills more than 99.999% of bacteria, viruses and fungi.
- Colorless and odorless
- pH neutral at 25 ppm or less
- Non-toxic, suited for children's toys, animals and pregnant women
- Chlorine-free option for swimming pools
Chitotec Oleum®
An organic antimicrobial additive for oil-based products. It protects against microbial contamination and extends the useful life of your product.
- Broad-spectrum antimicrobial activity
- Can be customized for specific industries
- Long-lasting: protection stays intact as long as the coating does
- Extends shelf life of cosmetics and oils

| Chitotec Polymer® | Chitotec Aqua® | Chitotec Oleum® | |
|---|---|---|---|
| Your product base | Plastics & polymers | Water-based | Oil-based |
| Added during | Masterbatch production | Formulation or dyeing | Formulation |
| Form | Masterbatch additive | Transparent liquid | Oil-based additive |
| Extra benefit | Makes polymers biodegradable | Chlorine-free pool option | Customizable per industry |
| Typical products | Packaging, films, filaments | Paints, textiles, sprays | Cosmetics, lubricants, oil paints |
Applications
Chitotec® is used in more than 250 industries. A few examples:
Eliminate Odors Permanently
Most products only cover up bad smells. Chitotec® works at the source: it stops the bacteria that cause odors from growing.
Built into clothing, sportswear, shoes or home textiles, it keeps them fresh for longer, safely and sustainably.
Our Commitment to Sustainability
Chitotec® Polymer breaks down through microbial enzymes into simpler, non-toxic substances, typically within a few months at industrial composting facilities. No microplastics left behind.
Biodegradable
Biodegradable polymers decompose in industrial settings within months. Standard: ISO 14855.
Compostable
Compostable polymers break down into nutrient-rich compost. Standard: ISO 13432.
Recycled polymers
Chitotec® helps unlock the full potential of recycled and bio-polymers for a circular economy.
