What Is Aluminium stearate?
The Stearate salts, including Lithium Stearate, Aluminum Distearate, Aluminium stearate, Aluminum Tristearate, Ammonium Stearate, Calcium Stearate, Magnesium Stearate, Potassium Stearate, Sodium Stearate, and Zinc Stearate are fine, white powders with a slight fatty odor. In cosmetics and personal care products, Stearate salts are used mainly in the formulation of makeup products such as eyeliner, eyeshadow, mascara, lipsticks, blushers, face powders and foundations. They are also used in fragrances, deodorants, and hair and skin care products.
Why is Aluminium stearate used in cosmetics and personal care products?
Aluminium stearate are generally used for their lubricating properties. Aluminium stearate also help to keep emulsions from separating into their oil and liquid components. The Stearate salts increase the thickness of the lipid (oil) portion of cosmetics and personal care products and reduce the clear or transparent appearance of finished products.
Scientific Facts of Aluminium stearate:
The commercial stearic acid from which the Aluminium stearate are manufactured is actually a mixture of monocarboxylic acids obtained from animal and/or vegetable sources.
Aluminium stearate
A white, wax-like powder that dissolves mineral spirits or hot oil. Imparts a short, buttery consistency, eliminates the separation of pigment and oil, thickens varnishes considerably.
Aluminium stearate (aluminum distearate) is a white, wax-like powder (metallic soap) that dissolves in mineral spirits or hot oil. A small amount (2% or less) added to oil paint imparts a short, buttery consistency. It eliminates the separation of pigment and oil, thickens varnishes considerably. A concentrate of Aluminium stearate and linseed oil can be prepared ahead of time and added to the paint whenever needed.
Aluminium stearate is made via the precipitation process using high quality stearic acid and exhibits the following properties: Good gelling and thickening action, excellent water repellency, transparency and a synergistic effect with zinc stearate or calcium stearate.
The effects of metal soaps on pigments have been extensively studied. Aluminium stearate was found to coat the surface of pigment particles and helped prevent settling as well as reducing the amount of oil needed to wet the pigment. The amount of Aluminium stearate needed to coat pigments varied on a weight basis, but a solution of 2% by weight (weight of Aluminium stearate/weight of oil) of Aluminium stearate was more effective than 0.5% or 4% solutions in altering pigment surfaces (Gardner 1930). The soaps coat the surface of the pigments and by steric effects keep the particles from aggregating (Pilpel 1963), which helps to keep the particles in suspension.
With increasing amounts of Aluminium stearate the oil pigment mixture becomes viscous, and by using an appropriate amount of Aluminium stearate the paint can gel at a lower pigment concentration (Mayer 1965). This can be used to create a “cheaper” paint since a smaller amount of a costly pigment needs to be used. A significant advantage of using stearates is that the oil and pigment do not separate greatly over long periods of time in the paint tube. Manufacturers of artists’ paints often use Aluminium stearate in their formulations without listing it as a component on the product label.
Solubility
Aluminium stearate exhibits relatively high solubility in hydrocarbon solvents (such as mineral spirits) when compared to other metallic stearates. It is insoluble in water, alcohol and ether; but is readily soluble in benzene, acids and common solvents when hot.
Storage
Aluminium stearate has long storage life if stored in cool and dry location.
How to Use
Aluminium stearate dissolves in vegetable oils on heating and if a high enough concentration of the soap is used, gelling occurs on cooling. In the usual practice of making paints, the Aluminium stearate is ground with the pigment before the bulk of the oil is added. To prepare a concentrated solution (10% w/v), add 100 grams of Aluminium stearate (nearly fills a half liter measuring cup without compacting) to one liter of linseed oil. Heat the oil to about 150° C. and gradually slowly adding the white powder to the hot oil with stirring. Add one part of this solution to four parts of oil by weight of oil before adding to pigments and grinding.

Applications of Aluminium Stearate
Aluminium soaps have different and widespread applications, Aluminium Stearates being especially important among them. Aluminium Tristearate is useful in paints and enamels and in the flatting of varnishes. It also prevents bleeding and oil separation in putty. Aluminium Distearate is the most commonly used grade of Aluminium Stearate.
Usage of Aluminium Stearate
Aluminium Stearate is used as a thickener in paints, inks and greases; a water repellent for leather and rope; and a lubricant in plastics and rope. It is also used in cement production for waterproofing and air entrainment, and in hot-melt paper coating compounds. Because of iAluminium Stearate’s unusually heavy bodying properties, Aluminium Monostearate is used in the manufacture of paints, inks, greases, and waxes. In recent years, hydrophobic Aluminium Monostearate was tested as a low-solubility denitrification substrate for anaerobic bacteria and a source of Aluminium for phosphate precipitation. Aluminium stearate has potential for use in a flow-through container for denitrification of oxidized effluent from home sewage systems.

Le stéarate d’aluminium, ou tristéarate d’aluminium, est un émulsifiant. Il est employé dans la fabrication de peintures et de lubrifiants3.
Le stéarate d’aluminium est aussi un additif alimentaire (E573) utilisé comme anti-agglomérant et émulsifiant, qui peut être employé dans le chewing-gum ou le café instantané4.
Qu’est-ce que le stéarate d’aluminium?
Les sels de stéarate, y compris le stéarate de lithium, le distéarate d’aluminium, le stéarate d’aluminium, le tristéarate d’aluminium, le stéarate d’ammonium, le stéarate de calcium, le stéarate de magnésium, le stéarate de potassium, le stéarate de sodium et le stéarate de zinc sont de fines poudres blanches avec une légère odeur de gras. Dans les cosmétiques et les produits de soins personnels, les sels de stéarate sont principalement utilisés dans la formulation de produits de maquillage tels que eye-liner, fard à paupières, mascara, rouges à lèvres, fards à joues, poudres pour le visage et fonds de teint. Ils sont également utilisés dans les parfums, les déodorants et les produits de soins capillaires et cutanés.
Pourquoi le stéarate d’aluminium est-il utilisé dans les cosmétiques et les produits de soins personnels?
Le stéarate d’aluminium est généralement utilisé pour ses propriétés lubrifiantes. Le stéarate d’aluminium aide également à empêcher les émulsions de se séparer en leurs composants huileux et liquides. Les sels de stéarate augmentent l’épaisseur de la portion lipidique (huile) des cosmétiques et des produits de soins personnels et réduisent l’apparence claire ou transparente des produits finis.
Faits scientifiques du stéarate d’aluminium:
L’acide stéarique commercial à partir duquel le stéarate d’aluminium est fabriqué est en fait un mélange d’acides monocarboxyliques obtenus à partir de sources animales et / ou végétales.
Stéarate d’aluminium
Une poudre blanche semblable à de la cire qui dissout les essences minérales ou l’huile chaude. Donne une consistance courte et beurrée, élimine la séparation du pigment et de l’huile, épaissit considérablement les vernis.
Le stéarate d’aluminium (distéarate d’aluminium) est une poudre blanche semblable à de la cire (savon métallique) qui se dissout dans les essences minérales ou l’huile chaude. Une petite quantité (2% ou moins) ajoutée à la peinture à l’huile confère une consistance courte et beurrée. Il élimine la séparation des pigments et de l’huile, épaissit considérablement les vernis. Un concentré de stéarate d’aluminium et d’huile de lin peut être préparé à l’avance et ajouté à la peinture en cas de besoin.
Le stéarate d’aluminium est fabriqué par précipitation à l’aide d’acide stéarique de haute qualité et présente les propriétés suivantes: bonne action gélifiante et épaississante, excellente hydrofugation, transparence et effet synergique avec le stéarate de zinc ou le stéarate de calcium.
Les effets des savons métalliques sur les pigments ont été largement étudiés. Le stéarate d’aluminium s’est avéré recouvrir la surface des particules de pigment et a aidé à empêcher la sédimentation et à réduire la quantité d’huile nécessaire pour mouiller le pigment. La quantité de stéarate d’aluminium nécessaire pour enrober les pigments variait en fonction du poids, mais une solution de 2% en poids (poids de stéarate d’aluminium / poids d’huile) de stéarate d’aluminium était plus efficace que des solutions à 0,5% ou 4% pour modifier les surfaces des pigments (Gardner 1930). Les savons enrobent la surface des pigments et, par des effets stériques, empêchent les particules de s’agréger (Pilpel 1963), ce qui aide à maintenir les particules en suspension.
Avec des quantités croissantes de stéarate d’aluminium, le mélange de pigments d’huile devient visqueux et, en utilisant une quantité appropriée de stéarate d’aluminium, la peinture peut atteindre une concentration de pigments plus faible (Mayer 1965). Cela peut être utilisé pour créer une peinture “moins chère” car une plus petite quantité d’un pigment coûteux doit être utilisée. Un avantage significatif de l’utilisation de stéarates est que l’huile et le pigment ne se séparent pas beaucoup sur de longues périodes dans le tube de peinture. Les fabricants de peintures d’artistes utilisent souvent du stéarate d’aluminium dans leurs formulations sans le mentionner comme composant sur l’étiquette du produit.
Solubilité
Le stéarate d’aluminium présente une solubilité relativement élevée dans les solvants hydrocarbonés (tels que les essences minérales) par rapport à d’autres stéarates métalliques. Il est insoluble dans l’eau, l’alcool et l’éther; mais il est facilement soluble dans le benzène, les acides et les solvants courants à chaud.
Espace de rangement
Le stéarate d’aluminium a une longue durée de stockage s’il est stocké dans un endroit frais et sec.
Comment utiliser
Le stéarate d’aluminium se dissout dans les huiles végétales lors du chauffage et si une concentration suffisamment élevée de savon est utilisée, une gélification se produit lors du refroidissement. Dans la pratique habituelle de fabrication des peintures, le stéarate d’aluminium est broyé avec le pigment avant d’ajouter la majeure partie de l’huile. Pour préparer une solution concentrée (10% p / v), ajoutez 100 grammes de stéarate d’aluminium (remplit presque un demi-litre de tasse à mesurer sans compacter) à un litre d’huile de lin. Chauffer l’huile à environ 150 ° C et ajouter progressivement la poudre blanche à l’huile chaude sous agitation. Ajouter une partie de cette solution à quatre parties d’huile en poids d’huile avant d’ajouter aux pigments et de broyer.
