Infobox references Sodium stearate is the sodium salt of stearic acid. This white solid is the most common soap. It is found in many types of solid deodorants, rubbers, latex paints, and inks. It is also a component of some food additives and food flavorings.[1] Use of Sodium Stearate Characteristic of soaps, sodium stearate has both hydrophilic and hydrophobic parts, the carboxylate and the long hydrocarbon chain, respectively. These two chemically different components induce the formation of micelles, which present the hydrophilic heads outwards and their hydrophobic (hydrocarbon) tails inwards, providing a lipophilic environment for hydrophobic compounds. The tail part dissolves the grease (or) dirt and forms the micelle. It is also used in the pharmaceutical industry as a surfactant to aid the solubility of hydrophobic compounds in the production of various mouth foams. Production of Sodium Stearate Sodium stearate is produced as a major component of soap upon saponification of oils and fats. The percentage of the sodium stearate depends on the ingredient fats. Tallow is especially high in stearic acid content (as the triglyceride), whereas most fats only contain a few percent. The idealized equation for the formation of sodium stearate from stearin (the triglyceride of stearic acid) follows: (C18H35O2)3C3H5 + 3 NaOH → C3H5(OH)3 + 3 C18H35O2Na Purified sodium stearate can be made by neutralizing stearic acid with sodium hydroxide. Sodium stearate INCI name: SODİUM STEARATE Chemical name: Sodium stearate EINECS / ELINCS number: 212-490-5 Its functions (INCI) Cleaning agent: Helps keep a clean surface Emulsifying agent: Promotes the formation of intimate mixtures between immiscible liquids by modifying the interfacial tension (water and oil) Surfactant: Reduces the surface tension of cosmetics and contributes to the uniform distribution of the product during its use Viscosity control agent: Increase or decrease the viscosity of cosmetics This ingredient is present in 0.5% of cosmetics. Deodorant stick (30.72%) Solid soap (4.45%) Sodium octadecanoate is an organic sodium salt comprising equal numbers of sodium and stearate ions. It has a role as a detergent. It contains an octadecanoate. Preparation of seed latex With suitable safety precautions, in suitable pressure equipment, the following latex is prepared. Since only 0.8 lb of this latex will be required in the second step of this procedure, the polymerization should be carried out on a suitably small scale.

To a solution of 804 parts of deionized, deaerated water, 8.25 parts of sodium stearate, 0.84 parts of 28% aqueous ammonia, and 0.84 parts of potassium persulfate is added, with agitation, 187 parts of vinyl chloride. The polymerization is carried out at 50°C for 25 hr. After venting, the resulting latex has an average particle size of 0.0342 μm.

(b) Emulsion polymerization with gradual addition With suitable safety precautions, a 15-gallon autoclave, fitted with an off-center, T-shaped agitator rotating at 200 rpm, is charged with 36.7 lb of deionized and deaerated water, 0.27 lb of potassium persulfate, 0.27 lb of 28% aqueous ammonia, 0.80 lb of the above seed latex, and 0.0066 lb of sodium stearate. The autoclave is evacuated, and 9.0 lb of vinyl chloride is pumped in. The reaction mixture is maintained at 50°C. After the polymerization has been initiated, additional monomer is pumped into the autoclave at a rate of about 2.5 lb/hr and a 5.25% aqueous solution of sodium stearate (which must be maintained between 40° and 60°C to prevent gelling) is pumped in at a rate of approximately 1.2 lb/hr. Table XIV gives more precise details of the addition schedule. The addition of monomer and surfactant is completed in 20 hr. Heating is continued for an additional 3.2 hr after completion of the additions.

About SODIUM STEARATE: Sodium salt of stearic acid, a naturally occurring fatty acid.Function(s): Surfactant - Cleansing Agent; Surfactant - Emulsifying Agent; Viscosity Increasing Agent -Aqueous; VISCOSITY CONTROLLING. Sodium stearate is a fine, white powder and the sodium salt of stearic acid, an emulsifier. It is a stabiliser and a thickener used in soaps, colour cosmetics, deodorants and in hair and skin care products. odium stearate is used to harden some of the Lush's ‘hot pour' soaps and solid deodorants. It helps to create a wide variety of large shapes and sizes from which we then cut fresh slices for our customers to take home. It has also the ability to make a product opaque and contribute to give soaps a creamy white foam. Lush has developed a palm-free soap base to eliminate palm oil from its products, however, it is very difficult to source a sodium stearate that is completely palm free. Currently, Lush is working with suppliers to produce a good alternative and tests have already been made, but we haven't been happy with the result. Fortunately, one of those palm-free versions has been successfully used in Orangutan Soap, which is promising for the future.Lush has developed a palm-free soap base to eliminate palm oil from its products, however, it is very difficult to source a sodium stearate that is completely palm free.

Multi-functional ingredient with thickening, gelling, and emulsifying properties. Widely used as thickener in stick products (e.g. deodorants) and co-emulsifier in cream and lotions. Add powder to the hot water phase (approx. 80oC / 176oF) and stir until homogeneous. Typical use level 0.5-20% (deodorant sticks 4 - 8%, bar soaps 5 - 20%, co-emulsifiers <1%) . For external use only. Stick cosmetics (e.g. deodorants), color cosmetics, soaps, creams, lotions, sunscreens, after sun care products. Sodium stearate is produced by saponification of vegetable oils and fats. The resulting stearic acid is then further purified by reacting it with sodium hydroxide.Does not contain animal derived components.Stearic acid is a saturated fatty acid that can deposit on the surface in special conditions. This acid is insoluble in water and soluble in ethanol. The copper substrate should be cleaned, pickled, and soaked in 10% volume HNO3 for oxide elimination. The clean sample should be soaked in ethanolic stearic acid solution (0.01 M) and 30 V DC should be applied. The anode and cathode should be made of copper. Studying the X-ray powder diffractometer (XRD) peaks proves the existence of copper stearate components resulting from the reaction of stearic acid with copper. The resulting component was studied using SEM (Figure 20). These components provide the necessary roughness and low energy of hydrophobia so the contact angle arrives at 153° and so the hysteresis of the contact angle decreases. Other researchers created a self-assembled layer on porous alumina using stearic acid. his method was performed on anodized aluminum in 0.01 volume of stearic acid solution in ethanol for 30 min without applying any potential and superhydrophobia was achieved. After having reduced the diameter as much as possible by hot rolling (smallest diameter approximately 5.5 mm), smaller diameters must be produced by cold drawing (see Golis et al., 1999; Schruff, 2004). Tension is applied to draw the hot rolled wire in several pulls down to a final required diameter between 1 and 2 mm. Calcium and sodium stearate are usually applied as a drawing lubricant. These soaps are particularly suitable at high drawing speeds because the lubricant film remains intact. Due to friction, temperatures above 150 °C and as high as 400 °C develop, which cannot be reduced by the cooling effect of the lubricant and air alone. Thus the dies are cooled with water and the wire with compressed air. Compared with earlier machines, modern dry wire drawing machines are more efficient with regard to the consumption of cooling water and lubricant as well as the filtration of stearate dust emissions. Dry wire drawing machines are machines that pull in the forward direction (Ruge and Wohlfahrt, 2001; Schimpke et al., 1977). They pull the wire as many as 14 times, i.e. a series of 14 drawing dies which are usually powered separately using rotational speed regulators. Due to the insolubility of stearic acid, it cannot be applied to sedimentation of magnesium stearate in an aqueous solution. With the addition of soda to stearic acid sodium, stearate would form, which is completely soluble in water. Magnesium stearate can be created by a reaction of magnesium sulfate, which is soluble in water, with sodium stearate, and the magnesium stearate would deposit in solution because it is insoluble in water. If magnesium chloride exists in solution other than magnesium stearate, then sodium chloride would also be produced. Of course, there is the possibility of its creation from a magnesium ion solution. The melting point of magnesium stearate is 85.5 °C, but the calcium stearate produced from the reaction of calcium oxide and stearic acid melts at 155 °C. Stearic acid was applied on the zinc oxide nanorods and the contact angle increased. The salts of the acids containing a long aliphatic chain are known as soaps. Soap pyrolysis is of interest mainly because special soaps are frequently used in the manufacturing of various plastics as slip agents (particularly Ca+ 2 and Zn+ 2 salts). The slip agents are used to avoid sticking of the polymer to the processing machines that work at temperatures of 200-300°C. Pyrolysis of soaps typically generates hydrocarbons. Sodium stearate at 300-350°C generates a mixture of decane, decene, tetradecane, pentadecane, etc. Calcium stearate also generates a mixture of hydrocarbons, but containing a considerable proportion of the corresponding ketone. Zinc stearate, a common slip agent, also generates by pyrolysis mainly hydrocarbons. Slightly soluble in water and in ethanol (96 per cent). Stable. Incompatible with strong oxidizing agents. As the sodium salt of stearic acid, sodium stearate is a highly functional material that can be applied in various fields, especially in cosmetic formulations, where it is effective to stabilize emulsions like lotions, make products thicker, more viscous. It is also widely used in the deodorant produce, in which it can serve as a major constituent of soap produced by saponification of oils and fats. Besides, it can be applied in the production of latex paints, rubbers, inks and also a component of some food additives and flavorings.

Zinc stearate, a common slip agent, also generates by pyrolysis mainly hydrocarbons. Slightly soluble in water and in ethanol (96 per cent). Stable. Incompatible with strong oxidizing agents. As the sodium salt of stearic acid, sodium stearate is a highly functional material that can be applied in various fields, especially in cosmetic formulations, where it is effective to stabilize emulsions like lotions, make products thicker, more viscous. Sodium Stearate is also widely used in the deodorant produce, in which it can serve as a major constituent of soap produced by saponification of oils and fats. Besides, Sodium Stearate can be applied in the production of latex paints, rubbers, inks and also a component of some food additives and flavorings. Besides, it can be applied in the production of latex paints, rubbers, inks and also a component of some food additives and flavorings. Sodium stearate is the sodium salt of stearic acid. This white solid is the most common soap.Sodium Stearate is found in many types of solid deodorants, rubbers, latex paints, and inks. It is also a component of some food additives and food flavorings. Characteristic of soaps, sodium stearate has both hydrophilic and hydrophobic parts, the carboxylate and the long hydrocarbon chain, respectively. These two chemically different components induce the formation of micelles, which present the hydrophilic heads outwards and their hydrophobic (hydrocarbon) tails inwards, providing a lipophilic environment for hydrophobic compounds. Sodium Stearate is also used in the pharmaceutical industry as a surfactant to aid the solubility of hydrophobic compounds in the production of various mouth foams. Sodium stearate is produced as a major component of soap upon saponification of oils and fats. The percentage of the sodium stearate depends on the ingredient fats. Tallow is especially high in stearic acid content (as the triglyceride), whereas most fats only contain a few percent. The idealized equation for the formation of sodium stearate from stearin (the triglyceride of stearic acid) follows.

Il est obtenu par hydrolyse en milieu basique ou saponification de la stéarine. À température ambiante, c'est une poudre blanche qui est un des composés des savons durs11. C'est une substance utilisée pour ses propriétés tensioactives. Outre les savons, elle est présente dans des préparations à destination de l'industrie chimique, pharmaceutique ou agroalimentaire. On la trouve dans de nombreux produits finis comme des bâtons de colle, sticks déodorants, crèmes à raser, préparations pour gâteaux ou crèmes glacées. Propriétés Le stéarate de sodium anhydre subit des changements de phase lorsqu'il est chauffé. En particulier, à partir de 130 °C il devient translucide et souple. Passé 200 °C, il est partiellement transparent et le devient totalement à partir de 265 °C2. Son point de fusion est compris entre 278 et 290 °C2. Propriétés spectroscopiques Spectroscopie infrarouge La spectroscopie infrarouge du stéarate de sodium montre plusieurs raies caractéristiques12,13 : de 2 800 à 3 000 cm-1, raies intenses correspondant aux modes de vibrations relatifs aux élongations des méthyles et méthylènes de la chaîne aliphatique ; à 1 556 cm-1, vibration d'élongation asymétrique du groupe carboxylate {\displaystyle {\ce {COO-}}}{\displaystyle {\ce {COO-}}} ; à 1 420 cm-1, vibration d'élongation symétrique du groupe carboxylate {\displaystyle {\ce {COO-}}}{\displaystyle {\ce {COO-}}}. Spectroscopie Raman La spectroscopie Raman à λ=514,5 nm13 du stéarate de sodium montre : à 2 840 cm-1 et 2 875 cm-1, des bandes intenses correspondant aux vibrations de valence symétrique et asymétrique des groupes méthylène {\displaystyle {\ce {CH2}}}{\displaystyle {\ce {CH2}}} ; à 2 918 cm-1, bande moyenne des vibrations d'élongation symétrique du méthyle terminal {\displaystyle {\ce {CH3}}}{\displaystyle {\ce {CH3}}} et 2 953 cm-1 pour l'élongation asymétrique ; à 1 437 cm-1, bande moyenne des vibrations de déformation des groupes {\displaystyle {\ce {CH2}}}{\displaystyle {\ce {CH2}}},{\displaystyle {\ce {C=O}}}{\displaystyle {\ce {C=O}}}, {\displaystyle {\ce {C-O}}}{\displaystyle {\ce {C-O}}} et élongation de {\displaystyle {\ce {C-O}}}{\displaystyle {\ce {C-O}}}. Solubilité Le stéarate de sodium est peu soluble dans l'eau à température ambiante. Sa solubilité augmente en présence d'alcool. Elle diminue en présence d'acide, de sel ou d'alcalino-terreux ({\displaystyle {\ce {Ca^{2+}}}}{\displaystyle {\ce {Ca^{2+}}}}, {\displaystyle {\ce {Mg^{2+}}}}{\displaystyle {\ce {Mg^{2+}}}})14. Propriétés détergentes Le stéarate de sodium est une substance amphiphile composée d'un groupe ionique carboxylate de sodium {\displaystyle {\ce {-CO2^{-}Na^{+}}}}{\displaystyle {\ce {-CO2^{-}Na^{+}}}} et d'un groupe hydrophobe CH3(CH2)n avec n=16.

C'est un tensioactif et il abaisse la tension superficielle de l'eau.

Sa température de Krafft est comprise entre 50 et 67 °C15,16.

La valeur HLB (hypophile-lipophile balance) est de 17,617.

Comme les autres savons, il perd sa capacité détergente nettoyante dans une eau dure ou acidifiée18.

Utilisations Surfactif anionique19 (agent de surface), il est employé comme excipient en galénique20 pour ses propriétés : solubilisante, émulsionnante, mouillante ou moussante.

Dans l'industrie chimique, le stéarate de sodium est utilisé pour l'enrobage du carbonate de calcium21,22.

Dans les activités de tréfilage, des bains de stéarate de sodium sont mis en place dans des lignes de décapage/lubrification chimique23,24,25.

Dans l'agroalimentaire, c'est un additif qui peut jouer le rôle d'émulsifiant, de stabilisant, d'épaississant ou encore de gélifiant26,27. Il est répertorié sous le numéro E470a en tant que sel de sodium d'acide gras.

On le trouve également dans les déodorants solides, les caoutchoucs, les peintures au latex et des encres.

Dans les années 1930, des combustibles colloïdaux ont été développés. Il s'agissait de suspensions de combustibles solides (charbon) finement divisés et dispersés dans de l'huile. Pour éviter la décantation des particules solides, l'état de dispersion était stabilisé par ajout de stéarate de sodium28,29.

Le stéarate de sodium est un produit intermédiaire lors de la fabrication d'autres stéarates (stéarate de magnésium, stéarate de calcium, stéarate d'aluminium ou stéarate de zinc) par le procédé de précipitation ou double décomposition :

{\displaystyle {\ce {C17H35COOH + NaOH -> C17H35COO^-Na^+ + H2O}}}{\displaystyle {\ce {C17H35COOH + NaOH -> C17H35COO^-Na^+ + H2O}}} {\displaystyle {\ce {2C17H35CO2^-Na^+ + M^{2+}Y2^- -> (C17H35COO^-)2M^{2+}{}+ 2Na^+Y^-}}}{\displaystyle {\ce {2C17H35CO2^-Na^+ + M^{2+}Y2^- -> (C17H35COO^-)2M^{2+}{}+ 2Na^+Y^-}}} (avec Y = Cl-, ½SO42-, etc., et M = Zn, Ca) Production Synthèse de laboratoire du stéarate de sodium anhydre L'équation de la réaction est la suivante30 : {\displaystyle {\ce {2C17H35CO2H + Na -> 2C17H35CO2^-Na^+ + H2}}}{\displaystyle {\ce {2C17H35CO2H + Na -> 2C17H35CO2^-Na^+ + H2}}} Par saponification Traditionnellement31 le stéarate de sodium était obtenu par hydrolyse alcaline du tristéarate du glycérol (ou stéarine) issu du suif de bœuf31 ou de mouton32.

L'équation de la réaction de saponification est la suivante : {\displaystyle {\ce {(C18H35O2)3C3H5 + 3NaOH -> 3C17H35CO2^-Na^+ + C3H5(OH)3}}}{\displaystyle {\ce {(C18H35O2)3C3H5 + 3NaOH -> 3C17H35CO2^-Na^+ + C3H5(OH)3}}}

Cette réaction est exothermique.

Double décomposition L'équation de la réaction de double décomposition est la suivante33 : {\displaystyle {\ce {C17H35CO2^-K^+ + NaCl -> C17H35CO2^-Na^+ + KCl}}}{\displaystyle {\ce {C17H35CO2^-K^+ + NaCl -> C17H35CO2^-Na^+ + KCl}}} Procédés Ittner et Twitchell Le stéarate de sodium est obtenu en deux étapes. La première consiste à produire l'acide stéarique, à partir des huiles végétales ou des graisses animales, par chauffage à la vapeur d'eau en présence de catalyseur (procédé Ernst Twitchell : acide sulfonique d'alkylbenzène et acide sulfurique dilué ; procédé Martin Ittner (en) : oxyde de zinc ou de calcium). {\displaystyle {\ce {(C18H35O2)3C3H5 + 3H2O -> 3C17H35CO2H + C3H5(OH)3}}}{\displaystyle {\ce {(C18H35O2)3C3H5 + 3H2O -> 3C17H35CO2H + C3H5(OH)3}}} L'acide gras obtenu est ensuite séparé du sous-produit : le glycérol par neutralisation avec une solution d'hydroxyde de sodium34,35 : {\displaystyle {\ce {C17H35COOH + NaOH -> C17H35COO^-Na^+ + H2O}}}{\displaystyle {\ce {C17H35COOH + NaOH -> C17H35COO^-Na^+ + H2O}}} STEARATE DE SODİUM N° CAS du stéarate de sodium: 822-16-2 "Bien" dans toutes les catégories. Nom INCI du stéarate de sodium : SODIUM STEARATE Nom chimique du stéarate de sodium : Sodium stearate N° EINECS/ELINCS du stéarate de sodium : 212-490-5 Ses fonctions (INCI) Agent nettoyant du stéarate de sodium : Aide à garder une surface propre Agent émulsifiant du stéarate de sodium: Favorise la formation de mélanges intimes entre des liquides non miscibles en modifiant la tension interfaciale (eau et huile) Tensioactif du stéarate de sodium : Réduit la tension superficielle des cosmétiques et contribue à la répartition uniforme du produit lors de son utilisation Agent de contrôle de la viscosité : Augmente ou diminue la viscosité des cosmétiques Le stéarate de sodium est présent dans 0.5% des cosmétiques. Déodorant stick (30,72%) Savon solide (4,45%) Le stéarate de sodium est une poudre blanche et fine ; il s'agit du sel de sodium de l'acide stéarique, un émulsifiant. Le stérate de sodium sert à stabiliser et à épaissir les mélanges de nos savons, nos déodorants et nos produits pour la peau ou les cheveux. De quoi s'agit-il? Le stéarate de sodium est un matériau du savon végétal issu des huiles de noix de coco et de palme. On le qualifie souvent de sel de sodium provenant de l'acide stéarique, un acide gras naturel. À quoi ça sert? Grâce à sa consistance, le stéarate de sodium est un composant majeur de la plupart des savons végétaux.
