    [0001] The present invention relates to a method of manufacturing a soap and a soap obtainable in particular by this method. There are various techniques for making soap. Industrial soaps are made from a mixture of an aqueous solution of a strong base and at least one fatty acid, the mixture is heated to above 60 ° C to accelerate the reaction. The glycerol formed during the saponification reaction is optionally withdrawn. The use of sodium hydroxide makes it possible to obtain solid soaps while potassium hydroxide makes it possible to obtain liquid soaps, more or less viscous. The artisanal method consists in carrying out the saponification reaction without heating the aforementioned mixture. The maximum temperature used in this method is 60 ° C which is the temperature reached by the aqueous solution of strong base, the reaction of the strong base with the water being exothermic. The saponification reaction is complete but slower in the absence of heat input. The soaps obtained by this cold method must therefore rest for a month or two for the saponification is complete, that is to say that the strong base is completely consumed in the reaction, this is what we call the cure. The cure also helps to dry the soap. The soaps obtained contain glycerol formed during the saponification and thus have skin softening properties. These soaps may also have other properties especially from their components. Nevertheless, the cure being long, there is a risk of rancidity of the soap during the cure. Rancidity does not alter the properties of soaps but leaves an unpleasant odor when used. The rancid soaps are unmarketable which causes a considerable loss for artisanal soap makers. In addition, sulfur is known to treat skin conditions such as psoriasis, for example. Thus, the article "In vivo study of biomechanical properties in psoriasis vulgaris: Effectiveness of 3035118 2 sulfur spa therapy" published in the journal Open Journal of Molecular and Integrative Physiology in 2013, 3, page 15-20 indicates that daily baths 20 minutes for 12 days in a thermal water at 35 ° C containing 173 mg / L of sulfur can improve the skin condition of 5 patients with psoriasis. Similarly, Aloe Vera is known for its properties in the treatment of psoriasis. Thus, the article entitled "Management of psoriasis with Aloe Vera extract in a hydrophilic cream: a placebo-controlled, double-blind study" published in the journal Tropical Medicine and 10 International Health, Volume 4, pages 505-509 in August 1996 , indicates that an ointment containing 0.5% by weight of Aloe Vera extract mixed with a mineral oil and castor oil can effectively treat psoriasis. An object of the present invention is to provide a novel method of making a cold soap which provides a dermatological soap containing glycerol and which does not rancid quickly. Another object of the present invention is to provide a novel method for producing a cold soap which makes it possible to obtain a dermatological soap having emollient and / or moisturizing properties.
    [0002] Another object of the invention is to provide a soap having softening and / or moisturizing properties and which is capable of treating at least one pathology of the skin and / or the scalp selected from eczema, in particular eczema. atopic, psoriasis, especially chronic forms of psoriasis and eczema acne, prurigo, urticaria, pityriasis, impetigo, atonic ulcers, varicose ulcers, keratoses, especially solar keratoses , para-keratosis, ichthyosis, skin allergies, especially in the sun and / or water, dandruff and mycoses. The present invention relates to a method of making a dermatological soap, wherein a saponification reaction is carried out by mixing at least one fatty acid ester with an aqueous solution of a strong base, the amount of fatty acid ester and strong base being such that said strong base is fully consumed in said saponification reaction; typically, according to the invention, said fatty acid ester or said fatty acid esters is / are liquid (s), at least one sulfur compound is added, especially in the form of sulphide (s) and / or sulfide ions S2- and / or hydrogen sulfide ions HS and / or thiosulfate ions S2032- and / or sulphates S042- and / or sulphites S032-, before and / or during and / or after said saponification reaction and the reaction mixture is maintained at a temperature substantially equal to or greater than 15 ° C and substantially equal to or less than 30 ° C and in particular substantially equal to 20 ° C throughout said saponification reaction. The use of liquid fatty acids makes it possible to obtain a homogeneous mixture at ambient temperature. Failure to heat the mixture reduces the risk of oxidation of the fatty acids or esters of fatty acids and in any case slows the oxidation reactions of these compounds which are responsible for rancidity. Moreover, the aforementioned saponification temperature makes it possible to reduce the oxidation of sulphides. It is known that the oxidation of aqueous sulfide takes place within a few days, but can be accelerated by increasing the temperature. The Applicant considers, without being bound to such an explanation, that it is probable that it is in particular sulphides and / or dissolved sulphurous hydrogen which act on the oxidation reactions of acids and fatty acid esters. Hydrogen sulfide is soluble in oils and other sulfide ionic sulfur species from the hydrogen sulfide reaction with water are also soluble. It is probably these oil-soluble species that react with fatty acids and / or fatty acid esters to slow down or reduce their oxidation.
    [0003] It is also possible according to the invention to carry out the aforesaid process at a temperature of less than or equal to 60 ° C, for example substantially equal to or less than 50 ° C or substantially equal to or less than 45 ° C or substantially at or below 40 ° C if, at this temperature, the oxidation of the sulfides is not accelerated relative to the oxidation taking place at a temperature substantially equal to 20 ° C. In fact, the oxidation kinetics of the sulphides is also influenced by factors other than the temperature, in particular the pH of the solution containing them. The means used to maintain the temperature at the above values are not limited according to the invention. Advantageously, the mixture is fractionated rapidly after the start of the saponification in small quantities in order to increase the heat transfer. After the commencement of said saponification reaction, it is possible to add aloe Vera, in particular in the form of a gel, and optionally at least one moisturizing agent chosen in particular from castor seed oil, avocado oil , Plukenetia volubilis oil, borage oil, rose hip oil and / or optionally at least one antioxidant, chosen in particular from 6-carotene, ascorbic acid, tocopherol and vitamin E. The Applicant has indeed found that Aloe Vera brings dermatological properties to the soap and that it does not accelerate the rancidity of the soap or, on the contrary delayed it. The addition of an antioxidant still helps to delay the rancidity of the soap. It is preferable to choose vitamin E and / or castor oil which also contains a large amount of vitamin E.
    [0004] According to a particular embodiment, the aqueous solution of said strong base is obtained by dissolving said strong base in water containing dissolved sulfur compounds, especially sulphurous water, and preferably having a total amount of sulfur. reducing agent (TRS) substantially equal to or greater than 6.0 mg / l and substantially equal to or less than 8.0 mg / l, in particular substantially equal to 7.3 mg / l.
    [0005] The Applicant has indeed found that the addition of the sulfur compound in this manner is effective in slowing down and / or reducing the rancidity of the soaps obtained. The sulphurous water is advantageously natural. Without being bound by this explanation, the Applicant considers that the presence of sulphides in the sulphurous water makes it possible to delay the rancidity of the soaps. The sulphurous water reacts with the base and gives a complex equilibrium of several ionic species which depends on the temperature and pH of the water. This mixture will react with fatty acids to slow down their oxidation.
    [0006] According to a particular embodiment, which can be combined with that mentioned above, said aqueous solution obtained is preferably used before the expiry of a period of 48 hours from the dissolution of said strong base. The Applicant considers, without being bound by this explanation, that the sulphides contained in the sulphurous water are oxidized during the aforementioned lapse of time or that the hydrogen sulphide has evaporated during this period. Indeed, it is known that hydrogen sulfide can evaporate rapidly in air depending on conditions such as the temperature, pH and salinity of the water in which it is dissolved. The species capable of reacting with the fatty acids and the fatty acid esters having disappeared, the oxidation of the latter is no longer slowed down. In addition, the soap obtained no longer has dermatological properties to treat the aforementioned pathologies. The strong base used may be sodium hydroxide (NaOH) or potassium hydroxide (KOH).
    [0007] Advantageously, the particularly sulphurous water used to obtain the strong aqueous base solution contains at least one mineral chosen from calcium, magnesium, sodium, potassium, silicon and fluorine and is free from Fe2 + ions. The equilibrium species in the water also depend on the hardness of the water. The absence of Fe 2+ ion makes it possible to retard the oxidation of sulphides, the ferrous ions are known to be a catalyst for the sulphide oxidation reaction. The possibly sulphurous water may have a total hardness substantially equal to or greater than 30 ° f and substantially equal to or less than 40 ° f and in particular substantially equal to 33 ° f. According to one embodiment, an amount of sulfur-containing compound (s) is added, substantially greater than or equal to 3.1% and in particular substantially equal to or greater than 3.35% of the total mass of acid (s). fat likely to react with said strong base. Such an amount allows the soap to be given dermatological properties and to treat acne, psoriasis and / or eczema. Said fatty acid may be chosen from fatty acids of plant origin, in particular from oleic acid, lauric acid, myristic acid, palmitic acid, stearic acid, ricinoleic acid, acid and the like. Linoleic acid, linolenic acid, capric acid, caprylic acid and mixtures of at least two of said acids and in particular mixtures of capric acid and caprylic acid with at least one fatty acid selected from oleic acid, lauric acid, myristic acid, palmitic acid, stearic acid, ricinoleic acid, linoleic acid and linolenic acid. Vegetable oils that are mixtures of fatty acids can be used. You can use olive oil, sweet almond oil, apricot oil, camellia oil, macadamia oil, hazelnut oil and argan oil. avocado oil, grape seed oil, sesame oil, hemp seed oil, evening primrose cotton and fractionated coconut oil which is a mixture of capric acid and caprylic acid. The Applicant has also found that the use of fractionated coconut oil considerably curbs rancidity and in particular, the combination of Aloe Vera gel and fractionated coconut oil made it possible to obtain soaps that can be stored for a very long time.
    [0008] Advantageously, the proportion of strong base / fatty acid (s) in said reaction mixture is such that, after saponification, at least one fatty acid remains in the soap obtained and that the percentage of fatty acid (s) remaining in the soap is substantially equal to or greater than 3% by weight of the soap and substantially equal to or less than 8% and in particular substantially equal to 6%. Such soap has softening properties for the skin leaving a greasy film. It is also possible to infuse during the dissolution of said strong base, saffron and / or a part of a plant, in particular leaves and / or bark, chosen from verbena, tea, orange and lemon. The infusion of saffron extracts antioxidant compounds contained in saffron. The rancidity of the soap is thus further reduced. The soap obtained frome an orange yellow foam that slightly colors the skin giving it a "good-looking" appearance.
    [0009] The infusion of other plants makes it possible to impart, in particular, different odors to the soap. The present invention also relates to a dermatological soap obtainable according to the process of the invention which comprises salts of at least one fatty acid and glycerol and which typically also comprises at least one sulfur compound, Aloe Vera, water and at least one mineral salt selected from calcium, magnesium, sodium, potassium, silicon and fluorine, is free from ferrous Fe2 + ions and further contains, optionally at at least one fatty acid ester and / or optionally at least one moisturizing agent chosen in particular from castor seed oil, avocado oil, Plukenetia volubilis oil, borage oil, rose hip oil and / or at least one antioxidant, chosen especially from 6-carotene, ascorbic acid, tocopherol and vitamin E. The Applicant has shown that the presence of sulfur-containing compounds in the soap, probably in the form of sulphides gives soap dermatological properties and makes it possible to treat diseases of the skin and / or the scalp chosen from eczema, in particular atopic eczema, psoriasis, in particular the chronic forms of psoriasis and eczema acne, prurigo, urticaria, pityriasis, impetigo, atonic ulcers, varicose ulcers, keratoses, in particular solar keratoses, para-keratosis, ichthyosis, cutaneous allergies, especially in the sun and / or in the skin. water, fungal infections and dandruff. The Applicant has found that the combination of aloe gel Vera and sulfur compounds allowed to treat at least one of the aforementioned pathologies by simple daily or bi daily use of the soap of the invention. It is indeed surprising that the use of a soap which remains in contact with the skin for a very limited time, unlike an ointment or a bath as described in the prior art can provide beneficial results. in the treatment of one of the abovementioned pathologies, in particular acne.
    [0010] DEFINITIONS The term "dermatological soap" means any soap, liquid or solid, that can be used on the skin and / or on the scalp without having a side effect or a reaction, in particular of contact, of such a magnitude that the skin or scalp could be considered as wronged. The term "fatty acid" denotes an aliphatic chain carboxylic acid which comprises at least one carboxylic acid function and the derivatives of these compounds, in particular the methylated or hydroxylated derivatives of these acids. The aliphatic chain may include one or more double bonds. The term "fatty acid ester" refers to a fatty acid ester comprising at least one ester function; it refers in particular triglycerides, that is to say esters of glycerol and a fatty acid as mentioned above.
    [0011] The term "liquid fatty acid" refers to a fatty acid in the form of a more or less viscous liquid such as an oil, for example, or a liquid wax. The term "sulfur compound" refers to any organic or inorganic compound containing at least one sulfur atom. It designates, for example, sulphides, and polysulfides, colloidal sulfur (elemental sulfur), thiosulfates, sulphates, sulphites, sulfur dioxide, the species formed during the reaction between H2S hydrogen sulphide and water, S 2 - sulphide ions, hydrogen sulphide ions, hydrogen sulphide ion salts, especially alkali and alkaline earth metal salts, dissolved hydrogen sulphide, thiols, sulfur containing ionic species, especially thiosulfate ion, carbon oxysulfides, carbon disulfide, alkali and alkaline earth metal sulfides and thio ethers.

Such water contains a large number of species in equilibrium, the number of species and their quantity depends on the pH of the water, its temperature and the mineral salts it contains. In sulfurous water, the sulfur may be in particular in the form of colloidal sulfur, sulphides, sulphates, thiosulphates and / or sulphites. Thus, sulfurous water according to the invention may contain at least one salt of a member selected from calcium, magnesium, sodium, fluorine, potassium and iron; these salts may be sulfur salts, the counterion comprising at least one sulfur atom. It may also comprise bicarbonate ions (an amount substantially equal to or greater than 300 mg / l and substantially equal to or less than 800 mg / l) of the SiO 3 ions, and fluorine.

FIGURES 1a and 1b annexed respectively represent the skin of a patient suffering from acne before use of the soap according to the invention and the skin of the same patient after three months of twice daily use of the dermatological soap according to the invention. EXAMPLES Production method An aqueous sodium hydroxide solution is prepared by dissolving sodium hydroxide crystals in water. The aqueous solution thus obtained is allowed to cool to room temperature, which is approximately a temperature substantially equal to 19 ° C or 20 ° C. In the aforementioned case, 330 g of caustic soda are dissolved in 590 g of water. Less than 48 hours after obtaining the above-mentioned aqueous sodium hydroxide solution and in the present case 12 hours later, 1440 grams of olive oil and 542 grams of fractionated coconut oil (liquid) are mixed. The mixture is filtered and the aqueous sodium hydroxide solution is incorporated. The mixture is mixed until a fine trace is obtained (the solution poured on a glass surface forms a trace) which indicates the start of the saponification reaction. 105 grams of aloe gel Vera, 105 grams of castor oil and 18 grams of vitamin E are then added. The composition thus obtained is mixed with the whisk. The soap paste is then poured into molds each containing 120 g of mixture being saponified. The rapid pouring and thus the fractionation of the paste makes it possible to increase the heat transfers with the ambient air: the soap paste always remains at a temperature of less than or equal to 30 ° C. The soaps obtained are stored for two months to ensure that the saponification reaction is complete. Influence of the chemical composition of the water used to obtain the aqueous sodium hydroxide solution Two soaps were manufactured according to the above process: a soap A for which the aqueous sodium hydroxide solution was manufactured with 590 g of sulfurous water whose composition is indicated below and a soap B for which the aqueous solution was obtained with 590 g of demineralized water.
    [0015] The amount of soda crystals remains the same for both soaps. Composition of the sulphurous water used for the manufacture of soap A The water temperature is 19 ° C; its pH is 7.16; its total hardness TH is 33 °, its calcium hardness is 17 ° and its magnesian hardness is 16 °. The following ions were also assayed according to conventional methods. [Ca2-1: 176mg / L [Mg2-1: 53.46mg / L] [NaI: 93mg / L [K-1: 3mg / L NH4-1: 0mg / L [Fe2 +]: 0 mg / L [HCO3]: 567.30 mg / L [C0321: Omg / L [Cl]: 62Mg / liter [N021: 0.05 mg / liter [Si0321: 55.11 mg / liter [F1: 0.11 mg / liter The absence of Fe 2+ ions contributes to slowing down the oxidation of sulfur, especially sulphides contained in water.
    [0016] 3035118 12 The water used contains a large amount of sulphides that are probably produced by the micro-bacterial flora and fauna. The amount of total reducing sulfur (TRS) is 7.36 mg / liter The amount of sulfur contained in the sulfides is 6.82 mg / liter The amount of sulfur contained in the sulfites is: 0.32 mg / liter The following species were also measured according to conventional methods. [S0421: 112 mg / L [S21: 0.81 mg / L [S20321: 0.7 mg / L [HS]: 5.46 mg / L 10 Influence of the amount of sulphurous water To test the influence of the amount of water used to make the sodium hydroxide solution, soaps were made according to the above-mentioned manufacturing method with 530 g of sulfurous water, the composition of which is indicated above, and 660 g of this same water. When the amount of water is 660 g, it was not possible to form soaps remaining solid. It is estimated that in excess of 600 g of water per 2087 g of total fatty acid esters introduced, it is not possible to form solid soaps.
    [0017] Influence of water composition on the dermatological properties of soap Soap A made from the above-mentioned sulfuric water has been tested in patients with acne, on patients with eczema and on patients. has psoriasis. Figs. 1a and 1b show the condition of the skin of a patient with acne before use of the soap A and after 3 months of twice daily use of this soap A. As can be seen in FIG. 1b, inflammatory areas and acne pimples are significantly reduced or have disappeared. Similar results were obtained after 3 months of soap A use on patients with eczema and psoriasis.
    [0018] 303 5 1 1 8 13 Such results were not obtained with soap B. The Applicant has therefore concluded, without being bound by such an interpretation, that the dermatological properties of soap A are due to sulphurous water and in particular with sulphurous water of the aforementioned composition.
    [0019] Influence of the time of use of the aqueous solution of sodium hydroxide A soap was prepared as indicated above just after the temperature of the aqueous solution obtained from sulfuric water as mentioned above has returned to a substantially equal value. at 20 ° C (the reaction of sodium hydroxide with water is exothermic). A soap was also prepared as indicated above 48 hours after obtaining the aqueous sodium hydroxide solution obtained by dissolving sodium hydroxide crystals in the aforementioned sulfurous water. Both soaps were cured for 2 months. The soap which has been prepared with the aqueous solution which has been stored for 48 hours no longer has the aforementioned dermatological properties, in particular on acne and psoriasis. The Applicant believes, without being bound by such an interpretation, that the sulphides contained in the water have been oxidized during the 48h period and that it is therefore probably the sulphides that give the soap its dermatological properties. Influence of the amount of sulphurous water used to obtain the aqueous solution on the dermatological properties of the soap A soap was made as indicated above using 530g of the above-mentioned sulfuric water and 540g of sulphurous water, respectively. The soap containing 530g of sulphurous water had no dermatological properties, especially on acne, eczema and psoriasis. In contrast, one prepared with 540g of sulphurous water had efficacy in the treatment of acne, psoriasis and eczema.
