UNE 55-624-1982 Detergent formula raw materials are measured using the silicon 02/sodium 20 or silicon 02/potassium 20 coefficient of the mercury content of potassium water glass.
This standard presents the formulas for calculating the Si02/Na20 or Si02/K20 ratios, respectively, in sodium or potassium silicates used as raw materials for detergent formulations. In this quotient, only Na20 or K20 combined to the silicate state is considered.
