Abstract
Detergent for dishwashing machines, of the type used both in industrial and household dishwashing machines, characterized in that it contains a mixture of alkaline compounds, salts and phosphonates used as sequestrants instead of the conventionally used phosphates, the phosphonates being a combination of hexamethylene diamine tetra (methylene phosphonate), hydroxyethyl amine di (methylene phosphonate), and citrates.
This detergent for dishwashing machines that is presented provides numerous advantages over the currently available systems, the most important being that phosphates/tripolyphosphates are eliminated from the detergent composition, obtaining a very low environmental impact, especially on aquatic ecosystems, enabling the regulatory parameters to be fulfilled and hence achieving the EcoLabel ecological detergent designation.
Description
- The present description relates, as its title indicates, to a detergent for dishwashing machines, characterized in that it comprises a mixture of alkaline compounds, salts and phosphonates used as sequestrants instead of the conventionally used phosphates, the phosphonates being a combination of hexamethylene diamine tetra (methylene phosphonate), hydroxyethyl amine di (methylene phosphonate) and citrates.
- At present, many and diverse types of detergents for dishwashing machines are widely known and used. They traditionally incorporate phosphates as an integral part of their composition, as seen, for example, in European Patents
2264160 "Detergent composition" and22174401 - Some attempts have been made to improve this situation, as described in Patents
ES 2079858 ES 2086236 - Phosphonates have also been used in detergents, as claimed for example, in European Patent
2228468 "Detergent compositions for dish washing that contain phosphonates that stabilize colour", but their use is complementary as a colour stabilizer and they never totally replace phosphates, which means that they still do not achieve compliance with the parameters laid down by the regulations, for them to be considered ecological detergents. - To solve the currently existing problems in regard to the use of phosphates and their contaminating effects, the dishwashing detergent that is the subject of the present invention has been devised, which uses a mixture of alkaline compounds, salts and phosphonates, said phosphonates being a combination of hexamethylene diamine tetra (methylene phosphonate), hydroxyethyl amine di (methylene phosphonate) and citrates. The phosphonates are used as sequestrants instead of the conventionally used phosphates.
- This detergent for dishwashing machines that is presented provides numerous advantages over the currently available systems, the most important being that the phosphates/tripolyphosphates are eliminated from the detergent composition, obtaining a very low environmental impact, especially on aquatic ecosystems.
- Another important advantage is that the composition of the detergent enables compliance with the regulated parameters for total chemicals, forbidden or restricted substances or mixtures, toxicity for aquatic organisms, critical dilution volume, biodegradability of organic compounds and washing efficacy, and thus achieves the EcoLabel ecological detergent designation.
- To gain a better understanding of the object of the invention, the attached drawing shows a preferred practical embodiment of the manufacture of the detergent for dishwashing machines. In said drawing figure -1- shows a simplified block diagram of the procedure for manufacturing the detergent for dishwashing machines.
- Figure -2- shows an example of a container that can be used for said detergent.
- The detergent for dishwashing machines that is the object of the present invention comprises, as can be seen on the attached drawing, the following elements:
- alkaline compounds (1): between 15% and 60% by weight
- salts (2): between 10% and 40% by weight
- phosphonates (3): between 1% and 15 % by weight.
- The phosphonates (3) are used as sequestrants and can be:
- hexamethylene diamine tetra (methylene phosphonate),
- hydroxyethyl amine di (methylene phosphonate),
- citrates,
- or a combination of the aforementioned.
- The phosphonates (3) replace the phosphonates that are conventionally used as sequestrants, they prevent limescale and are rust inhibitors. The mixture enhances the synergic power.
- The alkaline compounds (1) can be:
- sodium hydroxide,
- potassium hydroxide,
- meta sodium silicate,
- sodium carbonate,
- or a combination of the aforementioned.
- Sodium hydroxide or potassium hydroxide is used to maximize the degreasing effect of certain detergent formulations.
- Sodium silicate is used as an iron inhibitor and its different salts or oxides have a synergic effect with surfactants, keeping the pH of solutions stable.
- Sodium carbonate is used as an adjuvant in detergency and to control pH.
- The salts (2) can be
- sodium sulphate,
- sodium hydrogen carbonate,
- sodium chloride,
- or a combination of the aforementioned.
- Sodium sulphate is used as a pH regulator and dispersant.
- Sodium hydrogen carbonate increases the degreasing effect of detergents and generates a buffer effect on pH as well as contributing to the softening of water.
- Sodium chloride is used in the process as an ionic conductor.
- The procedure for the manufacture of a detergent for dishwashing machines according to this invention comprises two differentiated phases:
- mixing phase (4): carried out by adding, in a mixer, the alkaline compounds (1), the salts (2), and the phosphonates (3), until a homogenous finish with suitable viscosity is obtained. Preferably a stainless steel mixer is used, with blades at an angle of 35°, one rotation direction and a speed governor.
- filling phase (5): performed by gravity, in the containers through a filling device.
