Anionic surfactants are negatively charged materials that are available in a variety of chemical types. The main classes being alkyl ether sulfates, alkyl sulfates, alkylbenzene sulfonates, alpha olefin sulfonates, phosphate esters. They are used in a wide range of applications where they provide useful characteristics including, emulsification, solubilisation, wetting, detergency, dispersion foaming.
Nonionic surfactants carry no electrical charge they are available in in a variety of chemical types. The main classes being alcohol ethoxylates, alcohol ethoxylates/propoxylates, ethylene oxide propylene oxide copolymers castor oil ethoxylates amine ethoxylates fatty acid esters and their ethoxylates. They are used in a wide range of applications where they provide useful characteristics including, emulsification, solubilisation, wetting, dispersion, detergency, foaming defoaming.
Amphoteric surfactants can carry a positive of negative charge depending on pH, whereas cationic surfactants carry a positive charge there are a number of chemical types including for amphoteric surfactants betaines amidopropyl betaines, alkylamino dipropionates. They are used in a wide range of applications where they provide useful characteristics including, foaming, solubilisation, antistatic.
For many years we have been exploring the concept of engineering new surfactants using novel bio-based technologies. Sustainable products from renewable sources have been around for many years but the majority have very limited functionality in terms of performance compared to synthetic counter-types. Our remit was to develop a range of bio-based products that offer comparable performance against the synthetic products across a wide range of applications
Our company strength is our chemistry and market knowledge of surfactants in particular for applications that fall within the industrial markets. The coatings industry is an important market for Lankem and falls within two main areas; coating additives, which include dispersing agents, defoamers and humectants and emulsifiers for emulsion polymerisation. With many years of research and development, we have products that perform to the absolute highest standards.
Our company philosophy is to continue to develop new and interesting products to help the formulator bridge the demands of modern requirements.
Our latest BioLoop technology is both new and novel and helps to offer the formulator excellent sustainability profiling.
