Campo tecnico dell’invenzione Technical field of the invention
La presente invenzione riguarda un detergente per il lavaggio a mano di piatti e stoviglie interamente realizzato con acqua di mare e tensioattivi biodegradabili e il procedimento per la sua produzione. La presente invenzione è il risultato di numerosi anni di sperimentazione su formulazioni tese a migliorare la qualità dei detergenti per il lavaggio a mano di piatti e stoviglie, a ridurre i costi di formulazione e a diminuire l’inquinamento ambientale che normalmente i tensioattivi presenti in grande quantità in queste formulazioni possono provocare arrivando attraverso gli scarichi urbani nel mare. The present invention relates to a detergent for hand washing dishes and crockery made entirely with sea water and biodegradable surfactants and the process for its production. The present invention is the result of several years of experimentation on formulations aimed at improving the quality of detergents for hand washing of dishes and dishes, at reducing formulation costs and at decreasing the environmental pollution that surfactants normally present in large quantities in these formulations they can provoke arriving through the urban discharges in the sea.
Stato dell’arte State of the art
Le formulazioni dei detergenti per il lavaggio a mano di piatti e stoviglie sono composte da un solvente comunemente costituito da acque dolci industriali, acque potabili e acque demineralizzate, e da un soluto costituito da tensioattivi cationici, anionici, non ionici ed anfoteri che vengono additivati con coloranti, conservanti e profumi, a cui viene aggiunto sodio sotto forma di cloruro in forti concentrazioni, come addensante per fare in modo che il detergente abbia la densità voluta o sotto forma di soda caustica, come agente neutralizzante. The formulations of detergents for hand washing of dishes and dishes are composed of a solvent commonly consisting of industrial fresh water, drinking water and demineralized water, and of a solute consisting of cationic, anionic, non-ionic and amphoteric surfactants which are added with dyes, preservatives and perfumes, to which sodium is added in the form of chloride in high concentrations, as a thickener to ensure that the detergent has the desired density or in the form of caustic soda, as a neutralizing agent.
La domanda di brevetto EP-A1-1158040 descrive un detergente contenente tensioattivi cationici e anionici, la cui formulazione è costituita da acido dodecilbenzonato di sodio, etere solfato di sodio, Cocco amido propil betaina, cloruro di alchil dimetil idrossietil ammonio, soda caustica, acqua dolce, profumi, coloranti e conservanti. Patent application EP-A1-1158040 describes a detergent containing cationic and anionic surfactants, the formulation of which consists of sodium dodecylbenzonate acid, sodium ether sulphate, coconut starch propyl betaine, alkyl dimethyl hydroxyethyl ammonium chloride, caustic soda, water sweet, perfumes, dyes and preservatives.
Per produrre detergenti secondo le formulazioni descritte in EP-A1-1158040 occorre usare diversi tipi di tensioattivi e, grandi quantità di acqua dolce e grandi quantità di cloruro di sodio e di soda caustica. Sia la disponibilità di acqua dolce, che la disponibilità di grandi quantità di cloruro di sodio e di soda caustica implicano notevoli costi e consumi di energia per la loro produzione che comportano un notevole contributo all’inquinamento dell’ambiente. To produce detergents according to the formulations described in EP-A1-1158040 it is necessary to use different types of surfactants and, large quantities of fresh water and large quantities of sodium chloride and caustic soda. Both the availability of fresh water and the availability of large quantities of sodium chloride and caustic soda imply significant costs and energy consumption for their production which involve a significant contribution to environmental pollution.
FR-A1-2731435 descrive una composizione detergente liquida per la pulizia della pelle e /o dei capelli che comprende tensioattivi cationici, anionici e non ionici, acqua di mare debatterizzata e sostanze non biodegradabili come tri-etanol amina. FR-A1-2731435 discloses a liquid detergent composition for cleaning the skin and / or hair which comprises cationic, anionic and non-ionic surfactants, debacterized sea water and non-biodegradable substances such as tri-ethanol amine.

US-A-2006/0177522 descrive una soluzione ionica per sciacquare lenti a contatto. Questa soluzione ionica ha una composizione ionica che è della stessa qualità di quella dell'acqua di mare. Non è previsto l'uso di tensioattivi nella sua preparazione per evitare che l'assorbimento di queste sostanze nelle lenti a contato possa creare intolleranza negli occhi di chi le indossa. US-A-2006/0177522 discloses an ionic solution for rinsing contact lenses. This ionic solution has an ionic composition which is of the same quality as that of seawater. The use of surfactants is not foreseen in its preparation to avoid that the absorption of these substances in the contact lenses can create intolerance in the eyes of the wearer.
Sommario dell’invenzione Summary of the invention
Scopo della presente invenzione è di realizzare un detergente per il lavaggio a mano di stoviglie biodegradabile la cui composizione prevede l’uso di due soli tensioattivi anionici biodegradabili aventi come solvente l’ acqua di mare ed un metodo che realizza tale composizione in modo che i componenti risultino perfettamente sciolti nel solvente e che la profumazione e la colorazione non si alterino perdendo il profumo ed il colore iniziali. The purpose of the present invention is to produce a biodegradable hand washing detergent whose composition provides for the use of only two biodegradable anionic surfactants having sea water as solvent and a method which realizes this composition so that the components are perfectly dissolved in the solvent and that the fragrance and color do not alter, losing the initial perfume and color.
Al fine di ridurre nella composizione di un detergente sia il numero di tensioattivi presenti, sia il consumo di acqua dolce, sia il consumo di cloruro di sodio, la presente invenzione ha lo scopo di utilizzare l’acqua del mare pura. Il prelievo dell’acqua del mare viene effettuato in zone del mare incontaminate sotto il controllo di una società esperta in controlli analitici. In order to reduce in the composition of a detergent both the number of surfactants present, both the consumption of fresh water and the consumption of sodium chloride, the present invention aims to use pure sea water. The sampling of sea water is carried out in pristine areas of the sea under the control of a company expert in analytical controls.
In questo modo la formula del detergente viene arricchita di un notevole numero di sali che conferiscono al detergente una elevata azione sgrassante. In this way the detergent formula is enriched with a considerable number of salts which give the detergent a high degreasing action.
Nel mare sono presenti i seguenti sali: The following salts are present in the sea:
Cloruro di sodio, cloruro di magnesio, cloruro di potassio, solfato di magnesio, solfato di calcio, bromuro di potassio, ioduro di potassio, solfato di potassio,. Sodium chloride, magnesium chloride, potassium chloride, magnesium sulfate, calcium sulfate, potassium bromide, potassium iodide, potassium sulfate ,.
Questa miscela naturale di sali combinata con un numero limitato e una quantità modesta di tensioattivi idonei, realizza un prodotto con una bilanciata e sinergica miscela detergente e con un’elevata azione sgrassante, che agisce con quantità di prodotto ridotte e con risultati sorprendenti rispetto ai detergenti tradizionali. This natural mixture of salts combined with a limited number and a modest quantity of suitable surfactants, creates a product with a balanced and synergistic detergent mixture and with a high degreasing action, which acts with reduced product quantities and with surprising results compared to detergents. traditional.
L’obbiettivo della presente invenzione di realizzare un detergente per lavaggio a mano di piatti e stoviglie realizzato con acqua di mare e tensioattivi biodegradabili, prevede che il detergente risulti a pH neutro. Tale risultato non può essere raggiunto se si aggiunge l’acido dodecilbenzensolfonico all’acqua di mare in quanto non è possibile neutralizzare il pH con idrossido di sodio, in presenza di acqua di mare. La presente invenzione concretizza il superamento di questa difficoltà nel seguente modo, si neutralizza in un secondo serbatoio l’acido dodecilbenzensolfonico con idrossido di sodio fino a pH neutro fino a raggiungere il titolo del 25% e il dodecilbenzensolfonato di sodio 25% a pH Neutro viene stoccato in attesa di essere miscelato. The objective of the present invention to produce a detergent for hand washing of dishes and dishes made with sea water and biodegradable surfactants, provides that the detergent has a neutral pH. This result cannot be achieved if dodecylbenzenesulfonic acid is added to sea water as it is not possible to neutralize the pH with sodium hydroxide in the presence of sea water. The present invention realizes the overcoming of this difficulty in the following way, the dodecylbenzenesulphonic acid is neutralized in a second tank with sodium hydroxide up to neutral pH until the title of 25% is reached and the sodium dodecylbenzenesulphonate 25% at Neutral pH is stored waiting to be mixed.
I risultati sorprendenti del detergente oggetto della presente invenzione sono dovuti alla presenza dell’acqua di mare nella formulazione del detergente. Infatti basti pensare come nel giro di poco tempo il mare elimina da solo l’enorme quantità di scarichi di ogni tipo che visi riversano, proteggendosi grazie alla sua bilanciata miscela di sali di cui è composto. The surprising results of the detergent object of the present invention are due to the presence of sea water in the detergent formulation. In fact, just think how in a short time the sea alone eliminates the huge amount of discharges of all kinds that face, protecting itself thanks to its balanced mixture of salts of which it is composed.
Un ulteriore vantaggio del detergente realizzato con acqua di mare è che esso è più resistente nel tempo rispetto ai normali detersivi prodotti con acque dolci industriali. A further advantage of the detergent made with sea water is that it is more resistant over time than normal detergents produced with industrial fresh water.
Altro vantaggio, ancora, è che il detergente con acqua di mare, non deve essere additivato di cristallizzanti, ad esempio cloruro di sodio, né di addensanti di alcun tipo, in quanto l’acqua marina da sola realizza l’addensamento necessario per ottenere la densità caratteristica di questa tipologia di prodotto. Another advantage, again, is that the detergent with sea water must not be added with crystallizers, for example sodium chloride, nor with thickeners of any kind, since sea water alone creates the necessary thickening to obtain the characteristic density of this type of product.
Con il detergente oggetto della presente invenzione si ottengono i seguenti vantaggi: The following advantages are obtained with the detergent object of the present invention:
1) Ridotto consumo di acqua potabile in quanto si preleva l’acqua marina che poi ritorna al mare; 1) Reduced consumption of drinking water as the sea water is taken and then returned to the sea;
2) Si evita il consumo di cloruro di sodio, in quanto già presente nelle acque marine; 2) The consumption of sodium chloride is avoided, as it is already present in marine waters;
3) Si ha un minor consumo di detergente in quanto la formula realizzata con acqua di mare risulta più efficace di altri prodotti detergenti formulati con acqua dolce. 3) There is a lower consumption of detergent as the formula made with sea water is more effective than other detergent products formulated with fresh water.
4) Si realizza una diminuzione dell’inquinamento terrestre in quanto si utilizza meno detersivo per effettuare il lavaggio a mano di piatti e stoviglie che viene effettuato senza aggiunta di additivi per aumentare il potere sgrassante e addensante che diminuiscono la biodegradabilità. 4) A decrease in terrestrial pollution is achieved as less detergent is used to carry out the hand washing of dishes and crockery which is carried out without adding additives to increase the degreasing and thickening power which decrease biodegradability.
5) L’utilizzo dell’acqua marina nel detergente, ricca di sali, contribuisce a igienizzare i condotti di scarico durante la corsa fino al mare dell’acqua di lavaggio. 5) The use of sea water in the detergent, rich in salts, contributes to sanitizing the drainage ducts during the run to the sea of the washing water.
6) Inoltre poiché i tensioattivi sono già mescolati in formula con l’acqua marina, durante il percorso di ritorno al mare iniziano a biodegradarsi e quindi riversandosi nel mare producono minor inquinamento. 6) Furthermore, since the surfactants are already mixed in formula with sea water, during the return journey to the sea they begin to biodegrade and therefore, pouring into the sea, produce less pollution.
Ulteriore obbiettivo della presente invenzione è di realizzare un metodo di produzione che consente di ottenere il detergente oggetto della presente invenzione. A further object of the present invention is to provide a production method which allows the detergent object of the present invention to be obtained.
Il metodo di produzione di un detergente per il lavaggio a mano di piatti e stoviglie interamente realizzato con acqua di mare e tensioattivi biodegradabili è costituito dalle seguenti fasi: The production method of a detergent for hand washing of dishes and dishes made entirely with sea water and biodegradable surfactants consists of the following steps:
a) Si preleva l’acqua dal fondo del mare e si immagazzina in un primo serbatoio; a) The water is taken from the seabed and stored in a first tank;
b) Si aggiunge idrossido di sodio fino a pH neutro all’acido dodecilbenzensolfonico e si titola fino ad ottenere dodecilbenzensolfonato di sodio 25% a pH neutro, si raffredda e si stocca in un secondo serbatoio; b) Sodium hydroxide is added up to neutral pH to dodecylbenzenesulphonic acid and titrated to obtain 25% sodium dodecylbenzenesulphonate at neutral pH, cool and store in a second tank;
c) Si preleva tra il 50-70 % di acqua di mare e si invia in un miscelatore a pale, con velocità di miscelazione compresa tra 60 e 70 giri al minuto per evitare una eccessiva formazione di schiuma; c) Between 50-70% of sea water is taken and sent to a paddle mixer, with mixing speed between 60 and 70 rpm to avoid excessive foam formation;
d) Si aggiungono il 15-25% di dodecilbenzensolfonato di sodio 25% a pH neutro all’acqua di mare in agitazione nel miscelatore; d) Add 15-25% of 25% sodium dodecylbenzenesulphonate at neutral pH to the sea water stirred in the mixer;
e) Si invia all’interno del miscelatore il 20- 30% di alchil etero solfato di sodio 27% e) 20-30% of sodium alkyl ether sulfate 27% is sent inside the mixer
f) Si scioglie il colorante in acqua in un agitatore riscaldatore magnetico alla temperatura di 120 °C, agitando per 60 minuti, si versa una quantità pari allo 0.1-0.5% di colorante nel miscelatore; f) The dye is dissolved in water in a magnetic heating stirrer at a temperature of 120 ° C, stirring for 60 minutes, an amount equal to 0.1-0.5% of dye is poured into the mixer;
g) Si prepara il composto aromatizzante in quantità pari allo 0.1-0.5% del peso complessivo e si invia all’interno del miscelatore; g) The flavoring compound is prepared in a quantity equal to 0.1-0.5% of the total weight and is sent inside the mixer;
h) Si inserisce il conservante isothiazolin-3-one e 2-brom-2-nitropane-1,3-diol in quantità pari allo 0.05-0.2% del peso complessivo e si invia all’interno del miscelatore; h) The preservative isothiazolin-3-one and 2-brom-2-nitropane-1,3-diol is added in quantities equal to 0.05-0.2% of the total weight and is sent inside the mixer;
i) Si raddoppia l’agitazione inserendo una pompa che preleva la composizione dal fondo del miscelatore e la rimanda nella parte superiore del miscelatore per circa 120 minuti; la doppia agitazione si rende necessaria per rendere omogenea la miscela. i) The agitation is doubled by inserting a pump that takes the composition from the bottom of the mixer and sends it back to the top of the mixer for about 120 minutes; the double stirring is necessary to make the mixture homogeneous.
j) Il detergente viene lasciato riposare per 24 ore. j) The cleaner is left to sit for 24 hours.
