Storage of washing and cleaning agents.
Store soaps and synthetic detergents indoors, airy, at a temperature not higher than 35 ° C and a relative humidity not exceeding 70%. Storehouses should be protected against direct sunlight. Laundry detergents must not be stored near heat sources. There should be spaces between pallets containing collective packages, which allow air to circulate and prevent the packaging from getting wet.
The use of low temperatures in storage rooms and protection from direct sunlight are recommended to prevent the soaps from going rancid., and loss of fragrance in the washing and cleaning agents.
High humidity or temperature and humidity fluctuations favor the formation of tarnish on the soaps and powder caking. White, a dry deposit on the surface of the soap may form due to dissolution, followed by crystallization, occurring on the surface of the soap under the influence of changes in humidity, or as a result of an accompanying reaction with carbon dioxide in the air. The presence of this deposit does not substantially change the quality of the soap, it only changes its external appearance.
On the other hand, the appearance of white on the surface of the soap, but a greasy and greasy coating is the result of the soap molding process and becomes a disqualifying factor for the product. Mold usually develops first on the packaging, then switches to soap.
When storing soaps, they dry out, consequently their weight is reduced, so there are natural cavities. Despite the decrease in soap mass, the weight content of the ingredients determining the quality of the soap remains the same and the soap does not lose its value. A negative effect of this process may be the formation of cracks on the surface of the soap.
In the case of washing powders, changes in the weight of the product can also be observed depending on the humidity of the environment. Despite the weight changes taking place, soap and washing powders are generally sold according to the so-called. nominal weight, i.e.. the mass declared by the manufacturer on the packaging.
