(11) As mentioned earlier, the method for obtaining a product for obtaining a product for obtaining cleaning products from vegetable oils as defined above is part of the present invention, characterised in that it comprises the following operational steps: a) Heat the water to a temperature comprised between 40-60° C.; b) Add the xanthan gum at said temperature and with stirring until it is dissolved; c) Cut off the heat supply; d) Add the sodium stearate with stirring; e) Add the trisodium phosphate with stirring; f) Add the SDS with stirring; g) Optionally add brightener and/or perfume; h) Allow to cool to room temperature; and i) Add the volume of water evaporated in the process.

(12) To carry out step h), the product of step g) can be weighed and the volume of water evaporated in the process can be added. The product is then stored.

(13) In a particular embodiment, the method for obtaining the product for obtaining cleaning products from vegetable oils defined above is the one that consists of the steps indicated above.

(14) In a particular embodiment, the method for obtaining the product for obtaining cleaning products from vegetable oils defined above is carried out without adding aroma and/or perfume.

(15) In another particular embodiment, the method for obtaining the product for obtaining cleaning products from vegetable oils defined above is carried out by adding aroma and/or perfume.

(16) In another particular embodiment, the method for obtaining the product for obtaining cleaning products from vegetable oils defined above is carried out at 50° C.

(17) Therefore, in a particular embodiment, to obtain the product for obtaining cleaning products from vegetable oils, the water is heated to 50° C., and the xanthan gum is added with stirring until it is dissolved, moment when the heat supply is cut off, the sodium stearate is added with stirring, the trisodium phosphate is added with stirring, the SDS is added with stirring and it is allowed to cool to room temperature. The final product is then weighed and the volume of water evaporated in the process is added, to then proceed to store the product.

(18) In another particular embodiment, to obtain the product for obtaining cleaning products from vegetable oils, the water is heated to 50° C., and the xanthan gum is added with stirring until it is dissolved, moment when the heat supply is cut off, the sodium stearate is added with stirring, the trisodium phosphate is added with stirring, the SDS is added with stirring, the aroma and/or the brightener are added with stirring, and it is allowed to cool to room temperature. The final product is then weighed and the volume of water evaporated in the process is added, to then proceed to store the product.

(19) Said product or formulation is mixed with the vegetable oil to be recycled in the proportions described above, being subjected to a stirring process, which speeds up the conversion process without the need for heat input, obtaining a concentrated soap, to which the user can add water to his or her liking, depending on the specific needs of each case.

(20) Therefore, the method for obtaining cleaning products from vegetable oils is part of the present invention, characterised in that it comprises the following operational steps: a) The product for obtaining cleaning products defined above is poured at room temperature into a reactor, in a proportion by weight of the order of 90/127 (oil/product); b) The corresponding proportion of oil is poured under intense stirring; and c) It is left under intense stirring for the minimum time necessary to form the cleaning product.

(21) In a particular embodiment, the method for obtaining cleaning products from vegetable oils defined above is the one that consists of the steps indicated above.

(22) In another particular embodiment, the method for obtaining cleaning products from vegetable oils is characterised in that the product not containing brightener or perfume is used, and depending on the type of cleaning product that is intended to be obtained, after step c), brightener is added with stirring and/or perfume is added with stirring.

(23) The use of anhydrous trisodium phosphate increases the efficiency of the process of transforming oil into soap, the volume of water used in the formulation being reduced, which makes it easier to treat larger volumes of oil, together with the envisaged stirring process, which increases the reaction rate, although, as mentioned above, once the cleaning product is obtained, said product must be diluted with water.

(24) In a particular embodiment, the method for obtaining cleaning products from vegetable oils is one in which the time of step c) is between 0.5′ and 30′, preferably 10′.

(25) The process thus described would have a reaction time of the order of 20 to 30 seconds when working with conventional volumes of oil, a time that would not be substantially increased in case of working with large volumes. Nevertheless, the new formulation allows for automatic stirring with a propeller stirrer in a turbulent flow that would cause the transformation to take place in a few seconds, almost instantaneously.

(26) The described formulation is more sustainable, substituting the aroma for one that is non-allergenic and also having a neutraliser that leaves the final soap without any aroma, which allows the customer to provide the distinctive scent they want.

(27) The formulation may contain other components such as an anti-odour compound, generally in an amount of between 3 and 10% by weight. This compound can be added to the concentrated product used to obtain the soap or, alternatively, it can be added during preparation of the soap, in particular, before mixing the concentrated formulation with the oil; or alternatively it can be added once the soap has been prepared.

(28) Throughout the description and the claims, the word “comprises” and its variants do not intend to exclude other technical features, additives, components or steps. Moreover, the word “comprises” includes the case of “consists of”. For those skilled in the art, other objects, advantages and features of the invention may be partially deduced from both the description and the embodiment of the invention. The following examples are provided by way of illustration and are not intended to limit the present invention. Moreover, the present invention covers all possible combinations of particular and preferred embodiments indicated herein.

Example 7: Comparison of Cleaning Power Between Different Formulations According to the Invention and Comparative Formulations

(49) The product for preparing the soap and the soap are prepared in the same way as described in example 3. It is based on the following components and percentage:

Example 7a with 0.67% Xanthan Gum

(50) Water (83%) SDS (10.80%) Anhydrous trisodium phosphate (5.40%) Sodium stearate (0.17%) Xanthan gum (0.67%)

Example 7b with 0.57% Xanthan Gum

(51) Water (83.10%) SDS (10.80%) Anhydrous trisodium phosphate (5.40%) Sodium stearate (0.17%) Xanthan gum (0.57%)

Example 7c with 0.47% Xanthan Gum

(52) Water (83.20%) SDS (10.80%) Anhydrous trisodium phosphate (5.40%) Sodium stearate (0.17%) Xanthan gum (0.47%) Comparative example 7d (idem example 7c but with monosodium phosphate) Water (83.20%) SSDS (10.80%) Monosodium phosphate (5.40%) Sodium stearate (0.17%) Xanthan gum (0.47%)

(53) Example 7d (concentrated formulation) corresponds to the formulation of patent ES2650446B2, but wherein the amount of water has been reduced, such that the rest of the components have been concentrated. Given that once the soap is formed it must be diluted with water prior to use, after dilution the soap with which the cleaning power has been evaluated would have the same dilution conditions as that described in the example of patent ES2650446B2, specifically, the percentage of xanthan gum would be 0.2%.

(54) The performance is calculated from the cleaning power of the soap (volume of oil capable of dissolving). Therefore, the performance is determined by studying how much oil can be dissolved by the obtained soap. It is based on 100% performance (cleaning power) with the soaps obtained with soda, which are the ones that dissolve the greatest amount of oil (reference soap). For example, 98% performance means that it dissolves 98% of the oil that the soap obtained from soda would dissolve. Cleaning power of the soap obtained with soda (reference): 100% Cleaning power performance of the soap obtained with the formulation of comparative example 7d: 47.5% Cleaning power performance of the soap obtained with the formulation of example 7c: 91.5% Cleaning power performance of the soap obtained with the formulation of example 7b: 93.2% Cleaning power performance of the soap obtained with the formulation of example 7c: 98.3%

(55) The results indicate that performance goes from 47.5% with the formulation of comparative example 7d (which corresponds to the example of patent ES 2650446B2) to greater than 90%, even reaching 98.3% with the formulation of the present invention, thanks to the effect of the change in phosphate and the different percentage of xanthan gum.

(56) The effect of changing monosodium phosphate to anhydrous trisodium phosphate is illustrated by comparing comparative example 7d (monosodium phosphate) to example 7c of the invention (anhydrous trisodium phosphate). The saponification performance goes from 47.5% to 91.5%.

(57) The effect of the percentage of xanthan gum is illustrated by the examples of the invention. With the amounts claimed, the saponification performance is greater than 93%, even reaching 98.30% when the amount of xanthan gum is 0.67%.

(58) Likewise, the stability also increases in the formulations with the percentage of xanthan gum in the formulations of the present invention. Therefore, the stability of the formulation of comparative example 7d lasts for days, whereas it lasts for months for the soap prepared with the formulation of example 7a.
