[0001] The present invention relates to a product that is useful for obtaining cleaning
products such as soaps, floor cleaners, dishwashing liquids, detergents, and the like,
from vegetable oil, preferably used, to be able to effectively recycle said product,
as well as the production method thereof.
BACKGROUND ART
[0002] Making homemade soap is a simple manner to reuse a by-product at home such as used
vegetable oils, by using them as raw material for manufacturing our own soap. A product
that is ecological and sustainable is obtained, whereby not only we are responsible
with the environment but it also entails economic savings.
[0003] Bearing in mind that the average Spanish family generates an average of 10 litres
of used oil every year, and one litre of oil contaminates one thousand litres of water,
recycling said oil would stop polluting more than 0.8 m
3 of water per month.
[0004] It is known that saponification is resolved by means of using sodium hydroxide, potassium
hydroxide or a strong base, with the environmental and health risks (corrosion and
release of harmful vapours) that it can have on people.
[0005] Substituting soda and potash in saponification with sodium salts of phosphoric acid
has also been known for a long time, as in the case of patent
ES0184980; however, saponification performance is limited when used with used vegetable oils
and the result is not the desired one.
[0006] Patent document
US4806269A discloses a method for obtaining soap from used cooking oils. Said method can be
carried out by a consumer easily and with a high level of safety since strong bases
such as sodium hydroxide are not involved, but rather a formulation is used the components
of which include sodium phosphate in addition to other additives. This patent relates
to solid products that are mixed together with water and oil and cooking is required
to obtain the soap. Patent document
SU878779B also discloses a method for the saponification of used vegetable oil by treating
it with sodium phosphate. In this case, cooking is also required to obtain the soap.
[0007] Document
ES2650446B2 describes a formulation for the treatment of vegetable oils comprising sodium phosphate
as a saponifying agent, as well as other components such as sodium stearate and xanthan
gum, wherein in the method for obtaining the soap heating the mixture of oil and the
saponifying formulation is not required. However, the transformation speed is a bit
slow and only allows small volumes of vegetable oil to be treated.
[0008] Lastly, document
WO 2021191478A1 describes a concentrated formulation for the treatment of oils that uses anhydrous
trisodium phosphate instead of monosodium phosphate and a higher percentage of xanthan
gum with respect to the formulation of
ES2650446B2 and that allows larger volumes of oil to be treated with greater cleaning power.
[0009] Despite what is known in the state of the art, there is still a need to provide ecological
and sustainable formulations for soap preparation that are stable, provide a pleasant
aroma, and meet the requirements of the current legislation of the European REACH.
SUMMARY OF THE INVENTION
[0010] The inventors found that a formulation comprising a perfume with a component that
is a benzene ring having a C
1-C
6 alkyl group bound with an alcohol, acetate and/or aldehyde functional group can incorporate
an amount of up to 5% of said perfume without negatively affecting stability, at the
same time that it allows having a concentration of trisodium phosphate and sodium
dodecyl sulphate (SDS) such that classifying the formulation as corrosive or hazardous
according to the European REACH is not required, achieving high effectiveness or performance.
[0011] Unlike what happened when other perfumes were incorporated into the formulation of
the product for obtaining the soaps of the present invention, by incorporating the
perfume used in the present invention for the preparation of soap, said product showed
high stability. Furthermore, the use of the perfume according to the present invention
has the additional advantage that it is non-allergenic. For example, when a perfume
with a limonene content of around 50-55% was added, the product for obtaining soap
formulated with the rest of the ingredients and components of the present invention
but with said perfume was not stable and there was phase separation between the oily
phase and the aqueous phase. Similarly when using a perfume with a 10-20% 1-methyl-4-isopropyl-1-cyclohexene-8-ol
content, 5-10% 2,6-dimethyl-7-octen-2-ol content, the product for obtaining soap formulated
with the rest of the ingredients and components of the present invention but with
said perfume was not stable either and phase separation occurred.
[0012] Likewise, the product for the preparation of soaps of the present invention provides
a means that allows a good conversion ratio of oil into soap such that the amount
of product to be used is minimised, with minimum energy use. Specifically, the novel
product for the preparation of soaps allows between 15-20% more oil to be treated
than the product described in
ES2650446B2, due to the combination of components, selection of the type of perfume that is incorporated
into the formulation for preparing soap, component percentages, and pH of the formulation
of the present invention that is equal to or less than 12.
[0013] Regarding the product for preparing soap described in
WO2021191478A1, which is more concentrated than that of
ES2650446B2 and differs in some of the components with respect to this application, the product
for the preparation of soaps of the present invention manages to incorporate the perfume
in the formulation and by using a lower concentration of anhydrous trisodium phosphate
and SDS, whereby classifying the formulation as corrosive or hazardous according to
the European REACH is not required.
[0014] Both document
ES2650446B2 and document
WO 2021191478A1 describe products for the preparation of soaps that have a pH greater than 13, while
the pH of the product for the preparation of soaps of the present invention has a
pH equal to or less than 12.
[0015] In that sense, a first aspect of the present invention relates to a product for obtaining
cleaning products from vegetable oils, characterised in that it comprises the following
composition in % by weight: an aqueous solution of sodium dodecyl sulphate (SDS) in
an amount of between 2 and 7%; anhydrous trisodium phosphate in an amount between
3 and 4%; sodium stearate in an amount between 0.05 and 0.3%; xanthan gum in an amount
between 0.3 and 0.7%; a perfume in an amount between 2 and 5% having a pH between
6 and 8; and the amount of water required to reach 100% whereby a liquid formulation
is obtained; wherein the perfume comprises a component that is a benzene ring which
has bound thereto, in a position of the ring, a C
1 -C
6 alkyl group containing a functional group selected from the group consisting of alcohol,
acetate, aldehyde and mixtures thereof, wherein said component is found in an amount
of between 15-40% by weight with respect to the total components of the perfume; and
wherein the pH of the product is comprised between 9 and 12; or alternatively, the
product for obtaining cleaning products is a solid with the same components and proportions
(ratios) between them as the liquid formulation, except it does not contain water.
The water in this formulation is removed once the liquid formulation is prepared,
in general, before adjusting the content of the formulation to 100% with additional
water.
[0016] The inventors also found that the incorporation of sodium dodecyl sulphate (SDS)
in liquid form to the product of the invention for the preparation of soap allows
a better dissolution during the preparation of the product, being able to reduce the
amount thereof to even a concentration of about 2-3% by weight, with additional advantages
when using said product, such as less foam production, which for example means better
behaviour when used in a dishwasher, while a high amount of used oil is recycled.
Likewise, the inventors observed that by using liquid SDS heating the mixing cyclone
or reactor throughout the process is not required since all the components dissolve
at room temperature, with the consequent reduction of the CO
2 footprint and energy cost, so the fact that the method can be carried out at room
temperature entails important advantages at the industrial level.
[0017] In that sense, another aspect of the present invention relates to a method for obtaining
a cleaning product from vegetable oils as defined above, characterised in that it
comprises the following operational steps: 1. On water at room temperature and under
stirring, adding xanthan gum until dissolved; 2. Adding the sodium stearate with stirring;
3. Adding the trisodium phosphate with stirring; 4. Adding the SDS, optionally in
the form of an aqueous solution, and with stirring; 5. Adding the perfume with stirring;
and 6. Weighing the final product and adding the water until it reaches 100%, whereby
a product in liquid form is obtained; or alternatively, the water from step 5 is removed,
whereby a solid is obtained. The product thus obtained (whether it is obtained in
liquid or solid form) is stored until use thereof.
[0018] The product of the invention is applicable indistinctly to both small and large volumes
of oil to be treated. Likewise, it allows maximising the speed of transformation of
oil into soap, making it easier for the user to obtain soap by avoiding having to
heat the mixture and the gases that can be released during cooking, which makes it
easier to manage at the domestic level, its use not entailing any risk to people's
health. From this formulation it is possible to substantially increase the conversion
ratio; specifically, it can be obtained in an oil/formulation (v/w) ratio of, for
example, 0.35.
[0019] In that sense, another aspect of the present invention relates to a method for obtaining
cleaning products from vegetable oils, characterised in that it comprises the following
operational steps: a) Pouring the product for obtaining cleaning products as defined
above at room temperature into a reactor, in an appropriate oil/product ratio; b)
Pouring the corresponding proportion of oil under intense stirring; and c) Leaving
under intense stirring the minimum time required to form the cleaning product wherein
the product for obtaining cleaning products is used in liquid form, whereby if it
is in the form of a solution it is poured directly into the reactor and if it is in
a solid form it is reconstituted with water before pouring it into the reactor.

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

particular and preferred embodiments indicated herein.
EXAMPLES
[0046] Different formulations and methods for manufacturing the formulation and obtaining
soap are disclosed below. The percentages of the components are by weight relative
to the total weight of the composition.
Example 1: Preparation of a product for obtaining a cleaning product (200 litres of
soap) according to the invention
[0047] We started with the following components (% by weight):
- SDS (3%) 3 kg (as an aqueous solution at 20%): 15Kg of aqueous solution at 20% by
weight
- Trisodium phosphate (3.2%): 3.2 Kg (solid)
- Sodium stearate (0.1 %) 0.1 kg (solid)
- Xanthan Gum (0.55%) 0.55 kg (solid)
- Perfume (3%): 3 Kg
- Water up to 100kg
Total product: 100 Kg.
[0048] The perfume comprises between 20-30% phenethyl alcohol, and 1% aromas, and the rest
is water.
[0049] Method for preparing the product (100 kg)
- 1- On water at room temperature and under stirring, the xanthan gum was added until
it dissolved;
- 2- The sodium stearate was added with stirring;
- 3- The trisodium phosphate was added with stirring;
- 4- The SDS was added with stirring;
- 5- The perfume was added with stirring;
- 6- The final product was weighed and the water was added until reaching 100 final
Kg;
- 7- The product was stored.
[0050] Comparative example 1 using other perfumes that do not form part of the invention
[0051] The same method described above was repeated but using a perfume with a limonene
content of around 50-55%.
[0052] The product for obtaining soap formulated with the rest of the ingredients and components
of the present invention but with said perfume was not stable and there was phase
separation between the oily phase and the aqueous phase.
[0053] Similarly when using a perfume with a 10-20% 1-methyl-4-isopropyl-1-cyclohexene-8-ol
content, 5-10% 2,6-dimethyl-7-octen-2-ol content, the product for obtaining soap formulated
with the rest of the ingredients and components of the present invention but with
said perfume was not stable either and phase separation occurred.
Example 2: Preparation of a cleaning product from the product of Example 1
[0054] The following ingredients were added during preparation of the soap:
- Oil: 35 litres (liquid).
- 1- At room temperature, the 100 Kg of concentrated product were poured into the reactor;
- 2- The 35 litres of oil were poured under intense stirring;
- 3- It was left under intense stirring for 10 minutes;
- 4- The rinse aid was added with stirring;
- 5- The product was stored.
Oil/product ratio: 35/100= 0.35
Comparative example 2: Example of patent ES2650446B2
[0055] We started with the following components:
- Water (89.7%)
- Monosodium phosphate: 3.2%
- Sodium stearate: 0.1%
- Xanthan gum: 0.2%
- Sodium lauryl sulphates (SDS): 6.4%
[0056] The following components were added during preparation of the soap
- Perfume (0.4%)
- 29 litres (liquid)
[0057] Oil/product ratio of 3/10, more precisely 2.9/10= 0.29
[0058] In this example the perfume was added separately during preparation of the soap.
The pH of this formulation is greater than 13. The preparation is described in patent
ES2650446B2.
Example 3: Comparison of the cleaning power of the product of Example 2 with soap
obtained with soda
[0059] The performance is calculated from the cleaning power of the soap (volume of oil
capable of dissolving). In that sense, performance is determined by studying how much
oil the obtained soap can dissolve. It starts from a performance (cleaning power)
of 100% with the soaps obtained with soda, which are those which dissolve the greatest
amount of oil (reference soap). For example, a performance of 98% means that it dissolves
98% of the oil than soap made from soda would dissolve.
- Cleaning power of soap obtained with soda (reference): 100%
- Performance of the cleaning power of the soap of example 2 obtained with the product
of example 1: 95%.
[0060] Good performance is achieved and the stability of this soap lasts months.
