However, those skilled in the art will readily appreciate that the detailed description provided herein including the figures are presented for explanatory purposes and the embodiments extend beyond the currently described embodiments. For instance, the teachings and results presented in any particular described application may yield multiple alternative approaches and may be implemented in any suitable manner.

    [0040] The described embodiments may be implemented manually, automatically, and/or a combination of thereof. The term method refers to manners, means, techniques, and procedures for accomplishing any task including, but not limited to, those manners, means, techniques, and procedures either known to the person skilled in the art or readily developed from existing manners, means, techniques and procedures by practitioners of the art to which the embodiments pertains. Persons skilled in the art will envision many other possible variations that are within the scope of the claimed subject matter.

    [0041] The laundry detergent in sheets is a detergent for washing machines and hand laundry, specifically designed to have a minimum environmental impact and maximum respect for the people who use it by balancing all the aspects that characterize an eco-friendly next-generation product.

    [0042] The use of laundry detergent in sheets represents taking something small as doing laundry, but finding a way to have a large environmental impact.

    [0043] Its production comes from a formulation composed of ingredients that respect the environment and interact with each other to give an effective result without ever being aggressive to the environment or people.

    [0044] Eco-friendly ingredients that excellently replace those commonly used for the production of liquid and powder detergents currently on the market. The detergent in sheets is a safe product, made with a reduced number of ingredients, which are easily controlled in the production phase, both in terms of necessary quantities and for their interactions, thus avoiding any harmful side effects.

    [0045] Furthermore, compared to liquid detergents, laundry detergent sheets do not transport water and in any case, even in the production phase, a controlled and minimum quantity is used (it is purified water). This means that the laundry detergent in sheets allows a considerable saving of water, the most precious and necessary asset to allow life on our planet.

    [0046] The uniqueness of laundry detergent sheets lies not only in their formulation but also in the manufacturing process.

    [0047] Once the mixing of the ingredients has been carried out, which in the last phase is characterized by a state of vacuum, the production is carried out in a horizontal line by means of a progressive and controlled heating of the mixture. This allows maximum stability of the product, making the standard thickness necessary to guarantee the correct quantity of product.

    [0048] The product mix is made using a specifically calibrated mixer both in terms of revolutions per minute and pre-set times which also makes this phase unique and valid only for the formulation of the composition for making sheets of laundry detergent.

    [0049] Therefore, consistently ensuring each resulting sheet of product contains the same quantity of product with a precise standard of efficiency and effectiveness. This translates into the possibility of being able to assure the cleaning performance, which is always linked to other factors such as: water hardness, washing temperatures, state of the laundry, etc.

    [0050] The drying and solidification phase of the product is performed in a protected system which represents the heart of the production system.

    [0051] A microclimate is created, with variable temperatures and controlled in successive and consequent phases, which makes the system completely isolated from external temperatures.

    [0052] This allows the production of the sheets in a context of energy saving, as the production does not have to satisfy particular external temperatures which, without constant maintenance and control, have negative influences on the quality of the product. So, sheets of laundry detergent sheets are produced in a unique energy-saving process.

    [0053] The production process is followed by a packaging system that makes the sheet different also from the point of view of duration and maintenance of all its characteristics, not least those of an almost unlimited period of washing efficiency.

    [0054] The sheets of laundry detergent are protected by a recycled cellulose film which allows us to create completely plastic-free packaging completed by an FSC? cardboard box. The protective film is made of compostable material and therefore exceeds the most demanding parameters in terms of controlling the disposal of packaging materials. This cellulose film also has the property of guaranteeing an excellent and long-lasting degree of preservation of the product.

    [0055] The product inserted in the cellulose film of vegetable origin has a shelf-life of no less than 4 years from the date of production (clearly if the parameters of correct conservation are respected) in which all the characteristics are kept unchanged. Therefore, the correct humidity of the sheet, which makes it not only soft but also easily soluble in a minimum quantity of water during the washing process, the assurance of washing performance, and the complete absence of washing residues, both on fabric and in the washing machine, at the end of the washing cycle.
