Pionera biopolymer performance in hard water conditions

Laboratory work demonstrates the superior performance of Borregaard biopolymers compared to petrochemical-based products in lime scale inhibition and surfactant detergency

In laboratory work the performance of Borregaard plant-based biopolymers  is compared with polyacrylate (PA) benchmark.

Surface tension was measured under the following experimental conditions: 5mM SDS, 600ppm CaCl₂ hardness, 0.1% dispersant LP in water. Interfacial tension measured between mineral oil and water using spinning drop video tensiometer.

Key takeaways:

• Borregaard Biopolymer inhibits calcite scale better than a petrochemical-based polyacrylate
• Detergency is improved under hard water conditions
• Borregaard biopolymers protect appliances and improve cleaning
