Bio-based stabilisers for oil-in-water emulsions

Borregaard offers stabilisers based on sustainable and renewable raw materials for wax, AKD and other oil-in-water emulsions.

The structure of our bio-based additives differs significantly from the linear structure common to most synthetic emulsifiers. Surfactants and emulsifiers are designed to lower the interfacial tension between oil and water so that emulsion droplets can readily form.

The split between the lipophilic and hydrophilic part of the biopolymer molecules is less pronounced than for surfactants. Therefore, our biopolymers will not form micelles and will reduce surface tension in a linear manner, reaching a minimum of 40-50 mN/m at concentrations relevant for most practical emulsion applications.

Benefits offered:

  • Versatility - high adsorption affinity for a wide range of hydrophobic and hydrophilic materials.
  • Stability - tolerant to mechanical stress, temperature fluctuations, pH and electrolyte contamination.
  • Sustainable - 100% bio-based from renewable sources.
  • Safe - REACH exempt, certified in several FDA applications for food contact.
