Description

DESCRIPTION

LIQUID POTASSIUM SOAP AND PRODUCTION PROCEDURE

OBJECT OF THE INVENTION

The invention, as expressed in the title of this descriptive report, refers to a liquid potassium soap and the production process, providing, to the function for which it is intended, advantages and characteristics, which are described in detail below, which involve an improvement on the current state of the art.

More specifically, the object of the invention focuses on a handmade soap in the form of a liquid-gel that, with multiple applications, has the particularity of comprising in its composition only ingredients of 100% natural origin where the salts come from vegetable oils , and the excipients/vehicles are 100% of plant origin, no synthetic or animal origin, in particular based on avocado and olive oleins together with sunflower oil, a second aspect of the invention being the process for making said soap.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention falls within the chemical industry sector, focusing particularly on the field of soap manufacturing.

BACKGROUND OF THE INVENTION

As a reference to the current state of the art, although many types of soaps are known, at least by the applicant, the existence of none that has technical and structural characteristics equal to or similar to those of the one claimed here is unknown.

EXPLANATION OF THE INVENTION

The soap that the invention proposes, as mentioned above, is a handmade potassium soap product in liquid-gel form that, applicable for multiple uses, has the peculiarity of comprising only ingredients of 100% natural origin in its composition, where the salts come from vegetable oils, and the excipients/vehicles are 100% of vegetable origin, without any synthetic or animal origin. In particular based on avocado and olive oleins together with sunflower oil, a second aspect of the invention being the process for making said soap.

More specifically, the soap object of the invention comprises in its composition the ingredients indicated below:

- avocado and olive oleins,

- oleic high sunflower oil,

- KOH,

- K2CO3,

- ethyldiglycol,

- denatured ethanol with natural linalool,

- C8-C10 non-ionic surfactant,

- nonionic surfactant C5.

More specifically, said ingredients are preferably in the following proportions:

- avocado/olive oleins, 8.5%,

- high oleic sunflower oil, 35.7%,

- KOH 50% in water, 16.57%,

- K2CO3, 0.43%,

- ethyldiglycol, 8.5%,

- denatured ethanol with natural linalool, ECOCERT quality, 22.8%,

- nonionic surfactant C8-C10, 5.25%,

- nonionic surfactant C5, 2.25%.

For its part, the soap making procedure includes the following steps:

- The fat is mixed with the glycol and heated to a minimum of 40-50°C;

- while mixing and heating, the KOH K2CO3 solution is prepared;

- slowly add the previous alkali solution to the hot fat/glycol mixture. The approximate time depends on the amount of manufacturing, and can range from 1-2 hours with heating and stirring, to between 6-8 hours with heating only;

- the temperature is increased without reaching more than 80°C;

- before the mixture begins to thicken abruptly (a situation that occurs after the reaction of the alkali with the carboxylic groups of the fatty acids is achieved), the ethanol is added slowly, with which the viscosity decreases considerably;

- Once the previous mixture is homogeneous with the alcohol, the surfactants are added when the mixture cools below 50-60sC.

After homogenization, the product is ready for packaging.

With this, the soap has a dark coloration (greenish-black) from the oleins of olive oil and avocado that, preferably, are of Spanish origin.

It should be noted that the described composition of olein fatty acids is always adjusted and is generated from the mixture of avocado and olive. This olein is essential to achieve the particular aspect of the soap object of the invention. At the same time, it has a specific acidity that favorably influences the saponification process, unlike other less acidic oleins. The composition of saturated fatty acids is not high and is also a key factor for the liquid aspect of the formulation, unlike others with a higher content of saturated fatty acids that are the most used by other soaps on the market.

In addition, sunflower oil of the high oleic variety is also preferably used, since it is more specific and of higher quality than conventional sunflower oil, with a lower % oleic acid.

On the other hand, the surfactants used, preferably, come from inedible parts of cereals, which gives meaning to the concept of sustainability, since the origin is a residue that becomes a value product within a circular economy process. As it is not food grade, it does not compete in the market with useful ingredients in food. They are 100% biodegradable and ECOCERT certified as a natural product for use as a detergent or multipurpose cleaning product.

In addition, as a product for cleaning clothes, it does not require a softener because its high content of glycols and glycerin provides softness to the fabrics.

The product is therefore certifiable as organic within ECOLABEL.

It also has a characteristic bitter vegetable odor.

Finally, it should be noted that the soap is in a liquid-gel state at temperatures > 4°C, which is one of its main advantages, since other similar soaps on the market tend to be gelatin at these cold temperatures and are more difficult to process. in handling/use.

For its part, the technical specifications of the soap object of the invention are the following:

- Content of potassium salts from C7-C18 and C18 unsaturated fatty acids, >50%

- Appearance: liquid at T>4°C

- Vegetable smell

- Colour: dark brown-green

- pH (1%) = 10.5 ± 0.5

- Density (g/ml, 20°C)= 0.985 - 1.007

- Humidity (100°C)= 35.9 ± 5

- Glycerin generated during saponification, 4.5%

Finally, it should be noted that, in addition to the aforementioned use as soap for cleaning clothes, the soap of the invention is suitable for the following uses:

- In household cleaning:

General laundry cleaning (washing detergent)

stain remover for clothes

Cleaning, care and renewal of leather

Dish cleaning (dishwasher)

Floor cleaning (floor cleaner)
