Working temperature on the technical data sheet
A detergent's use temperature is on its technical data sheet, under «Dose and method of use», with the dose and time; it varies by product type.
When reading the data sheet, it is worth distinguishing three figures. The use temperature is that of the solution or surface during cleaning. The «Density (20 °C)» in the technical data only indicates the temperature at which density was measured. And phrases such as «store at temperatures not exceeding 50 °C» refer to storage, not use. If the data sheet does not state a use temperature, it should not be assumed that the product needs hot water. Some data sheets give a range and others a maximum, above which performance drops. The reasons for these ranges are explained in Detergent working temperature.
How temperature appears on Instaquim data sheets, by product type:
- Industrial dishwasher: Deternet, from 1 to 5 g/l depending on water hardness, at 55–60 °C; the rinse aid Deterbrill, from 0.1 to 0.5 g/l in the final rinse, at 65–80 °C.
- Laundry detergents: the enzymatic Gold at about 40 °C; the alkaline Solmatic, between 60 and 80 °C.
- Laundry bleaching agents: the data sheet gives a maximum. Cobat (active oxygen) performs best below 50 °C and Adiclor (chlorine) below 60 °C.
- Disinfectants: Oxa Per states a use temperature of 20–50 °C at 1 % and 15 minutes; Clor NF Pro, 2 to 8 % at 20–60 °C and 5–15 minutes. The dose, time and temperature on the data sheet go together.
