Description

The present invention seeks to solve the problem of scrubbing with a cloth washcloth rough, rough by the addition of solid residues, the addition of a new component, micros grains of sand, in the composition, manufacture soft soap. The invention relates to a composition in the form of a dark paste, characterized in that it contains in mixture at least 30% of the olive-pomace oil by weight relative to the total weight of the oily material, a part of micro grains of sand, and the use of said composition for scrubbing the skin. The present invention relates to a new soft body exfoliating soap. The invention also relates to a process for the preparation of this composition. The soft soap or black soap, used in traditional Arab societies, since 2000 years, in the hammam, in association with a rough cloth washcloth, called kessa glove, the soft soap associated with the glove in rough fabric, allows a scrub and deep cleansing of the skin. To be able to perform the scrub of the skin, one needs the soft soap and the glove in rough fabric, it is necessary to have these two elements, products. The action of the cloth glove granular fabric, rough associated with soft soap allows scrubbing, deep cleaning of the skin. The kessa glove is the name given to a rough washcloth used in the Orient. Originally it was made of goat hair, it is now made only synthetic material, acrylic, the acrylic material allows fast drying, is wrinkle resistant, and resistant. The kessa washcloth is made of rough granular material, that is to say composed of small rough grains that one feels to the touch. The kessa glove is used in hammams for the realization of the mechanical scrub with the traditional black soap. The word "kessa" originates from the Arabic word kiss meaning little bag. The hammam is the place par excellence in which kessa is the most used in combination with soft soap.

The soap is called "soft", in that it is pasty, in that it is composed of potash, and lipid constituents of vegetable origin, olive-pomace oil. It comes in the form of a dark, thick paste that when mixed with water becomes creamy. The soft soap is all natural, 100% biodegradable, without chemical substance. The soft soap is also called "black soap", in that the soft soap obtained is dark in color, preferably brown to black and this color comes from olive pomace oil, used in the composition and manufacture soft soap, preferably at least 60%, more than 80% by weight relative to the total weight of other oils used in the manufacturing process, hence the name of black soap. Olive-pomace oil contains molecules from the skin of olives or pulp, which give this oil its dark, dark color. Composition of soft soap for centuries: The soft soap is characterized in that it is saponified olive pomace oil, at least 60% of olive pomace oil, by weight relative to the total weight oily materials, alone or in combination with other oils (palm oil), with potash, soda, in a hot pot. Thus, the soft soap is composed of saponified olive paste, water, sodium hydroxide, and potash. The saponification reaction is carried out traditionally in cauldron. Oily materials, potassium carbonate, water are placed in a kettle and heated to a boiling temperature of 100 ° C. Soft soap has existed in Morocco for centuries, black soap is part of the hygiene products of Moroccan cosmetics. The city of Essaouirra, is the historic capital of the manufacture of black soap. The applicant has endeavored to preserve traditional manufacturing methods, derived from ancestral know-how practiced in Morocco for the manufacture of soft soap. At the same time, the Applicant has sought to improve the washing base of traditional soft soap, in order to provide a soap having exfoliating, scrubbing, stripping properties, than that of the prior art. And so, solve the technical problem, namely the use of a rough fabric washcloth, rough, to perform the scrub of the skin. Thus, the subject of the invention is a process for the manufacture of a soft body-exfoliating soap containing lipid constituents of vegetable origin, of olive-pomace oil, characterized in that it contains micro grains of sand. . The presence of micro grains of sand in the composition of soft soap, confers exfoliating properties, exfoliating. The use of this soap deep cleanses the skin, and in particular, eliminate dead skin, dead cells, orange peel, toxins, free pores, reduce existing roughness level of certain parts of the body: elbows, knees, heels, and so leave the skin soft and smooth.

The present invention seeks to solve the problem of scrubbing with a rugged, rough fabric glove by adding a new component, the micro grains of sand, in the composition, making the soft soap. The invention consists of the combination, mixing the soft soap with micros grains of sand. This process is used to perform the scrub of the skin under the mechanical effect of micros grains of sand, by rubbing the skin, circular movements with the hands, without the need for a scrub glove granular tissue, rough. The action, the interaction of the micro grains of sand with the soft soap base brings scrubbing properties, exfoliating identical to those of the soft soap associated with the rough washcloth. The micro grains of sand are similar to the acrylic, granular material of the kessa washcloth, which is composed of small rough grains that feel to the touch. Sand is a granular material consisting of small particles from the disintegration of other rocks whose size is between 0.063 and 2 millimeters. The size, shape and granular nature of the sand grains make it suitable for skin scrub, similar to the rough washcloth.

To obtain such a soap, the micros grains of sand must be incorporated in certain proportions. The subject of the invention is thus a soft body-exfoliating soap characterized in that the weight of the micro-grains of sand represents 5 to 20% of the total weight of the soap and in particular a soft body-exfoliating soap, characterized in that the weight of the micro-grains sand represents 12% of the total weight of the soap. In addition, the micro sand grains used preferably have a size of between 100 and 200 microns. Advantageously, it is possible to incorporate micro grains of colored sand, of different colors. The body exfoliating soft soap, object of the present invention may also comprise grains of fine sand, preferably having a size between 0.1 and 0.3 millimeters, very preferably 0.1 millimeters. The invention also aims to facilitate the use of soft soap to the consumer, who will no longer need to use a cloth washcloth rough, rough to perform the skin scrub.

So far, the main obstacle, the disadvantage of soft soap, is the need to use it with a rough granular tissue scrub glove, to be effective, that is to say to obtain a thorough cleaning of the skin. skin. Creams containing exfoliating, exfoliating substances intended to be applied to the body already exist on the market.

Compared to the cream form, the soft soap form has the advantage of having a much greater cleaning power. Indeed, the soft body exfoliating soap, object of the present invention, cleans thanks to a mechanical effect due to the presence of micros grains of sand. On the other hand, the soft form of the soap makes it possible to better insist on the rough parts of the body and a better spread of the product. Finally, a soap is removed with water much faster than a cream, the use of a soap is easier than that of a cream. From the hygienic point of view, the soft soap and the micro grains of sand have the advantage of dissolving with water. The soap molecule and the grease are entrained with the rinse water. The soaps produced from soda and potash are soluble in water. Advantageously, the soft exfoliating soap is a natural product which once evacuated in nature, it decomposes easily. The new soft soap exfoliating with micro grains of sand, object of the present invention, is intended to be applied only on the body and not on the face. The micro grains of sand it contains are soft, inert and non-irritating. The micro grains of sand allow, by being incorporated in the soap, to perfectly clean the skin gently and deeply. As already mentioned above, the main advantage of the soft body exfoliating soap is to eliminate the roughnesses, but also the dead cells and the various impurities existing on the surface of the epidermis. In addition, by its mechanical exfoliating effect, the exfoliating soft soap stimulates the superficial circulation, provides a real feeling of well-being. It leaves the skin smooth and soft and prepares the skin to receive the body care products. This exfoliating soft soap must have a high exfoliating power while being non-irritating.

Among the lipid components contained in the soft exfoliating soap, it is advantageous to incorporate argan oil. The latter is among the vegetable oils one of the richest in essential fatty acids, essential nutrients that the skin can not produce itself. However, the deficiency of essential acids leads to phenomena on the skin (dryness, premature wrinkles ...). Argan oil contains 43% oleic acid.

Argan oil means any oil extracted from the almond trees of the argan tree, endemic to Morocco. The argan oil cosmetic, is used in application on the skin and would have virtues against the cutaneous dehydration. Researcher Zoubida Charrouf, who specializes in organic chemistry at the University of Rabat, has contributed a lot to the scientific knowledge of this oil. Argan oil thanks to its richness in omega-6 essential fatty acids and tocopherols (vitamin E), antioxidants that prevent the drying of the skin, and necessary for the epidermal cellular integrity, regenerates the cells of the epidermis . In addition, the argan oil added to a soap base, allows to obtain a type of soap "surgras", that is to say non-aggressive and non-drying. Thus, according to one embodiment, the soft microsilver sand soap of the invention may contain a natural supergratifying agent, preferably argan oil, sweet almond oil, and shea butter. According to the embodiment of the invention, the oily raw material may comprise olive-pomace oil in combination with one or more other oils, excluding palm oil, olive, linseed oil, coconut oil.

When a combination of oil is used, the olive pomace oil represents more than 30%, preferably more than 80% by weight relative to the total weight of the oils used in the process. It can be associated 1-17% preferably 14% coconut oil and 0-3% preferably 2% palm oil, 5-15% argan oil or almond oil soft, preferably 12%, by weight relative to the total weight of the oils. According to one embodiment, the soft soap with the micro grains of sand of the invention may contain a natural moisturizing agent, preferably chamomile, monoi, rose, honey, particularly suitable for sensitive skin.

The body exfoliating soft soap, object of the present invention may also comprise a soft soap with micro grains of antibacterial sand, with antiseptic ingredients. Another object of the invention is a soft soap with micro grains of fragrant sand, embellished with scents of sandalwood, amber, orange blossom, jasmine extract, lemon extract, Eucalyptus, preferably a natural scent.

According to one embodiment of the invention, solid residues other than micros grains of sand, preferably shredded fruit stones other than olives, preferably ground apricot kernels, are added to the soft soap of the plant. 'invention. The addition of these solid residues or shreds brings the same effects as the micros grains of sand, namely exfoliating, stripping and scrubbing properties. According to one embodiment of the invention, the addition of solid residues other than micros grains of sand, very preferably wheat germ, oat flakes, ground coffee, corn flour, seeds of poppy, or crushed apricot kernels or fruits other than olives, represents 5 to 20% of the total weight of the soap, and constitutes 100% of the exfoliating, exfoliating material used in the composition of said soft exfoliating soap. As a soap base, it is preferable to use a mixture of saponified olive paste, water and potash. The raw materials for making soap are fats, fats or oils and soda (or potash) and water. Reaction with caustic potash KOH (potassium carbonate or potassium hydroxide) gives a soft soap. The manufacture of soft soap is therefore the result of a slow and non-reversible transformation called saponification, at the end of this transformation, the ingredients used have disappeared. Saponification is the chemical reaction transforming the mixture of an ester (fatty acid) and a strong base, usually potassium hydroxide (KOH) or sodium hydroxide (NaOH), into soap and glycerol at a boiling point included between 80 ° and 100 ° C. Thus, the subject of the invention is a soft body-exfoliating soap characterized in that it is capable of being obtained by saponification of an oily substance comprising at least 10%, preferably 20% by weight. at 50%, very preferably at least 30% olive pomace oil, by weight relative to the total weight of the oily matter, with potash, and micros grains of sand. The soft exfoliating soap of the invention comprises 30 to 65% of salts of fatty acids, chosen from potassium olivate, potassium cocoate and potassium palmate. Saponification is conducted in the presence of potash and soda. Olive pomace oil is saponified, alone or in combination with other oils, with potassium hydroxide and / or potassium carbonate, and / or soda in a hot pot, at a temperature of boiling of the mixture between 80 and 100 ° C., until the saponification reaction is complete. 10 to 50% saponification, very preferably 30 to 45% olive pomace oil, 1-15% coconut palm oil, 0-3% potassium carbonate, 8-17% of potash, 0-2% sodium hydroxide in 30 to 60% water, preferably rain water, distilled water, or demineralised water. Indeed, if the water is mineralized (hard), saponification will be more or less good depending on the amount of minerals in the water. Soda will use some of its energy to neutralize these minerals, so we will always use the same water, among the waters mentioned above. The percentages are given by weight relative to the total weight of the mixture before the start of the reaction. The soap obtained is naturally amber, dark, dark, dark brown to black and this color comes from olive-pomace oil, used in this embodiment in a quantity of at least 30%, ie more than 80% by weight relative to the total weight of the other oils used in the process. The olive-pomace oil used in the invention is a crude olive-pomace oil extracted by mechanical (physical) pressing from olive pomace. The olive-pomace oil used does not contain a piece of pulp, stone or solid residues of olives.

The body soft exfoliating soap with micro grains of sand, object of the present invention is preferably used 1 to 2 times a week in the shower, bath or steam room. The soap of the invention does not contain dyes, and does not contain ink. The soft soap with micro grains of sand according to the invention does not contain preservative and is completely natural.

On a hot and moist skin, the body is rubbed directly with the exfoliating soft soap by emphasizing the rough parts (elbows, knees, heels). This process makes it possible to scrub the skin under the effect of micros grains of sand, by circular movements, friction of the skin with the hands, without resorting to a scrub glove in rough, rough fabric, glove traditionally used to perform the deep skin scrub, in combination with the soft soap. This is an innovation brought to the product, by adding solid residues, adding a new component, micros grains of sand, in the composition, the manufacture of soft soap, the mixture, the interaction, the action of micro sand grains with the washing base, provides scrubbing, exfoliating properties, and facilitates the use of soft soap to the consumer, who will no longer need to use a fabric washcloth rough, rough to scrub the skin. Another object of the invention is to facilitate the production, the industrialization of the soft soap, thanks to the mixture, to the combination of two elements, the soft soap washing base and the sand micro-grains constituting a single product, namely a soft body exfoliating soap with micro grains of sand. The invention is susceptible of industrial application, thanks to the mixture of the vegetable paste (soft soap) and micros grains of sand, combined together, in a single product, to obtain the same result, the same efficiency, as the soft soap in combination with a scrub glove 25 of rough fabric. The mixture, the interaction of the soft vegetable paste with micros grains of sand, makes it possible to obtain a single product, a soft soap exfoliating body, and thus facilitates the production, the standardization, and the marketing of the product. The following example illustrates the invention without limiting it. The oily raw material is brought into contact with the strong base (potash, soda) in the presence of water at a boiling point of 100 ° C. in a stainless steel cauldron. Like the Aleppo soap, the soft exfoliating soap object of the present invention is made by the so-called cauldron process which consists in cooking the soap paste until complete saponification of the oils. In a second step, when the mixture reaches a temperature below 50 ° C, very preferably a temperature between 35 and 45 ° C, the micros grains of sand are incorporated, so that they impregnate the mixture, before it does not solidify completely, and without it being too liquid, because if the mixture is too liquid, the micros grains of sand tend to be deposited at the bottom of the container, cauldron. In the case of the use of an oil surgrasse, such as argan oil, sweet almond oil, shea, it is incorporated in the mixture last, at a temperature between 30 and 35 ° C, so as not to lose its nourishing, softening properties for the skin. The mixture is recovered and cooled to room temperature and then packaged in pots. By ambient temperature is meant a temperate temperature. The soap can be kept for several months in a cool, dry place.
