WebThis purely physical absorption mechanism is independent of the chemical characteristics of the liquid; therefore both polar as well as non-polar liquids can be absorbed. The finished absorbate can contain between 50 – 75% of the liquid actives; silica thus outperforms other traditional solids used in powder detergent formulations. WebThe calculation of the DOA absorption number based on dried substance can be calculated on the basis of the following formula and is given without decimal place.
