Colloidal lignin instead of chemically synthesized additives
- for UV protection, biocides, antioxidants, emulsifiers, drug carriers
- natural and sustainable alternative to ecologically problematic ingredients
- multifunctional, sulfur-free biomaterial particles
- extracted from woody residual biomass
- UV absorbing, antibacterial, antioxidant effect
- additionally suitable as a physical emulsifier and active agent carrier
- biodegradable
- environmentally sound, efficient production process - 1-step, easily scalable
- high raw material variability: can be produced from all types of wood to woody biomass - e.g. from agriculture and forestry, garden centers, food production
Level of innovation
- sustainable production process, without problematic auxiliary substances; smart process design without multiple precipitation – global novelty!
- first public presentation at the HM 2020
- protected by patents
Target groups
- cosmetics (COSMOS, NATRUE compliant), food, pharmaceutical, packaging, textile, dye, paint and coating industry
- manufacturers of ingredients for these industries
- companies and organisations with biomass residues
- plant engineering
