Description

o9 o63 1 2954778 BREVET SAVON D'OLIVE 11DESCRIPTION DE L'INVENTION La présente invention porte sur la création d'une base lavante liquide exclusivement composée de produits de saponification d'huile d'olive. SUMMARY OF THE INVENTION The present invention relates to the creation of a liquid washing base exclusively composed of saponification products of olive oil.

La saponification des corps gras (triglycérides) permettant d'obtenir des sels d'acides gras est connue par l'homme de l'art depuis plusieurs siècles, Cette réaction chimique peut être réalisée par action de lessives de soude (savon solides) ou par action de lessive de potasse (savons mou) sur tous les triglycérides. Elle peut en général être mise en oeuvre par action d'un agent nucléophile sur un triglycéride. The saponification of fatty substances (triglycerides) making it possible to obtain salts of fatty acids is known to those skilled in the art for several centuries. This chemical reaction can be carried out by the action of sodium hydroxide solution (solid soap) or by action of potash lye (soft soaps) on all triglycerides. It can generally be carried out by the action of a nucleophilic agent on a triglyceride.

Il existe de nombreux savons liquides et produits d'hygiène corporelle obtenus par saponification d'huiles de coco, de palme ou de graisses animales. There are many liquid soaps and body care products obtained by saponification of coconut oils, palm oil or animal fats.

Quelques produits peuvent contenir des produits de saponification de l'huile d'olive en tant que composé mineur. La saponification communément mise en oeuvre conduit à des savons liquides et produits d'hygiène corporelle qui nécessitent l'ajout de plusieurs adjuvants chimiques pour être commercialisés. Some products may contain saponification products of olive oil as a minor compound. The saponification commonly used leads to liquid soaps and personal hygiene products that require the addition of several chemical additives to be marketed.

25 Les savons liquides et produits d'hygiène corporelle classiques, même s'ils peuvent être constitués pour tout ou partie des produits de saponification de triglycérides, contiennent au moins un des additifs suivants : Conventional liquid soaps and personal hygiene products, even if they can be constituted for all or part of the saponification products of triglycerides, contain at least one of the following additives:

• Conservateur (pour éviter la prolifération bactérienne) 30 • Chélatant (pour éviter le trouble provenant de sels divalents) • Agents viscosant (pour régler la viscosité). La règlementation européenne s'oriente de plus en plus vers des produits naturels contenant le moins d'agents chimiques possible (Directive 76/768/CEE du Conseil du 27 juillet 1976 concernant 35 le rapprochement des législations des États membres relatives aux produits cosmétiques (directive «Cosmétiques») • Preservative (to prevent bacterial growth) • Chelant (to avoid turbidity from divalent salts) • Viscose agents (to control viscosity). European regulations are increasingly geared towards natural products containing the fewest chemical agents possible (Council Directive 76/768 / EEC of 27 July 1976 on the approximation of the laws of the Member States relating to cosmetic products (Directive "Cosmetics")

Nous avons mis au point une formule de savons liquides et de produits d'hygiène corporelle (gel douche, crème de douche, etc.) par saponification directe et exclusive de l'huile d'olive qui 40 permet d'obtenir, après dilution du mélange réactionnel de saponification, un produit directement commercialisable, sans que l'addition d'aucun adjuvant ne soit nécessaire. We have developed a formula of liquid soaps and personal hygiene products (shower gel, shower cream, etc.) by direct and exclusive saponification of the olive oil which makes it possible to obtain, after dilution of the saponification reaction mixture, a directly marketable product, without the addition of any adjuvant being necessary.

La composition du produit final ainsi obtenu est la plus simple chimiquement-possible. Pour obtenir cette formulation, la réaction de saponification doit être conduite dans des conditions 45 très précises afin d'éviter la prise en masse du mélange réactionnel tout en permettant une vitesse de réaction exploitable industriellement. The composition of the final product thus obtained is the simplest chemically possible. In order to obtain this formulation, the saponification reaction must be carried out under very precise conditions in order to avoid the build-up of the reaction mixture while allowing an industrially exploitable reaction rate.

Les paramètres plus particulièrement sensibles sont : température la concentration en agent nucléophile et le ratio nucléophile/triglycéride. 50 La température de réaction doit être comprise entre 30 et 100 degrés Celsius, de préférence entre 60 et 80 degrés. La concentration en agent nucléophile doit être comprise entre 10 et 50%, de préférence entre 20 et 30% L'agent nucléophile doit être utilisé en défaut stoechiométrique de 2 à 0.002%, de préférence entre 55 0.1et1%. 2 2954778 Le produit obtenu présente les avantages suivants, démontrés par des tests : • Très faible irritabilité : 5 La plupart des produits naturel d'hygiène sont obtenus à partir de sels d'acide gras à coute chaine saturée (C 12 à c 15). Ces produits très moussants sont irritants. L'utilisation d'huile d'olive conduisant à des produits d'hygiène exclusivement composés de produits de saponification de l'huile d'olive permet d'obtenir des produits essentiellement constitués de sels d'acides gras à longue chaine insaturée (acide oléique, linoléique et linolinique) 10 qui sont peu irritants. The more particularly sensitive parameters are: temperature, nucleophilic agent concentration and nucleophilic / triglyceride ratio. The reaction temperature should be between 30 and 100 degrees Celsius, preferably between 60 and 80 degrees Celsius. The nucleophilic agent concentration must be between 10 and 50%, preferably between 20 and 30%. The nucleophilic agent must be used in stoichiometric defect of 2 to 0.002%, preferably between 0.1 and 1%. The product obtained has the following advantages, demonstrated by tests: Very low irritability: Most natural hygiene products are obtained from saturated fatty acid salts (C 12 to C 15) . These very foaming products are irritating. The use of olive oil leading to hygiene products exclusively composed of saponification products of olive oil makes it possible to obtain products consisting essentially of salts of long chain unsaturated fatty acids (oleic acid linoleic and linolinic) which are mildly irritating.

De plus, le procédé mis en oeuvre exige un défaut de base par rapport à la stoechiométrie de la réaction, ce qui permet de consommer tout l'agent nucléophile corrosif. Le produit fini contient donc des traces de tri, di et mono glycérides d'huile d'olive, ce qui le rend 15 particulièrement peu irritant pour la peau ou les yeux. In addition, the method used requires a basic defect with respect to the stoichiometry of the reaction, which makes it possible to consume all the corrosive nucleophilic agent. The finished product thus contains traces of tri, di and mono glycerides of olive oil, which makes it particularly non-irritating to the skin or the eyes.

• Autoconservation Les produits de saponification de l'huile d'olive permettent d'obtenir des produits d'hygiène qui ne nécessitent pas l'addition de quelque conservateur que ce soit. 20 Bien que les solutions aqueuses soient connues pour être très propices au développement d'algues ou de bactéries les rendant impropres à la consommation, les produits obtenus par une saponification exclusive de l'huile d'olive se conservent seuls et résistent de façon remarquable à l'attaque des microorganismes. Les challenge tests effectués sur la formule et le procédé objets de la présente invention, associés à 25 des tests physicochimiques de vieillissement montrent que le produit est stable plus de 36 mois tant sur le plan chimique que sur le plan bactériologique. • Self-preservation The saponification products of olive oil make it possible to obtain hygiene products that do not require the addition of any preservative. Although aqueous solutions are known to be very conducive to the development of algae or bacteria rendering them unfit for consumption, the products obtained by an exclusive saponification of olive oil are preserved alone and resist remarkably well. the attack of microorganisms. The challenge tests carried out on the formula and process which are the subject of the present invention, associated with physicochemical aging tests, show that the product is stable for more than 36 months both chemically and bacteriologically.

• Agents viscosant Les produits d'hygiène liquides obtenus entre autre par saponification des triglycérides conduisent 30 à des solutions très liquides qui nécessitent l'ajout d'agents de réglage de la viscosité. Les produits de saponification de l'huile d'olive conduisent à des mélanges de sels d'acides gras dont la viscosité peut être réglée en jouant sur leur concentration, sans que l'addition d'additifs viscosant ne soit utile. Viscosing agents Liquid hygiene products obtained inter alia by saponification of triglycerides lead to very liquid solutions which require the addition of viscosity control agents. The saponification products of olive oil lead to mixtures of fatty acid salts whose viscosity can be adjusted by adjusting their concentration, without the addition of viscosity additives being useful.

35 La présente invention sera plus complètement décrite dans l'exemple suivant qui ne doit pas être considéré comme limitatif de l'invention : The present invention will be more fully described in the following example which should not be considered as limiting of the invention:

Exemple : Charger dans un réacteur de 100 litres un poids pesé précisément d'environ 20 kilogrammes 40 d'huile d'olive. Porter à une température de 50 degrés environ. Préparer par dilution de lessive de potasse à 50% une solution à 25%. La quantité de base précisément pesée est de 3.781 kg exprimé en potasse pure. Couler la solution de potasse sur l'huile en agitant en maintenant la température entre 70 et 90 45 degrés. La fin de la réaction (6 à 8 heures) est mesurée par l'évolution du pH pris sur un échantillon de mélange réactionnel. Quand la réaction est terminée (PH inférieur à 10), ajouter de l'eau purifiée par osmose inverse, distillation ou déminéralisation de façon à obtenir une masse totale de mélange réactionnel de 50 117.6 kg. Le produit ainsi obtenu peut être utilisé tel quel ou parfumé avec des huiles essentielles ou tout parfum utilisé habituellement en savonnerie. L'addition au mélange réactionnel précédent de savon de baies de laurier permet d'obtenir la forme liquide du savon d'Alep. 55 3 Example: Loading in a 100-liter reactor a weight weighed precisely about 20 kilograms 40 of olive oil. Bring to a temperature of about 50 degrees. Prepare by dilution of potassium hydroxide solution at 50% a 25% solution. The quantity of base precisely weighed is 3.781 kg expressed in pure potash. Pour the potash solution on the oil while stirring, keeping the temperature between 70 and 90 degrees. The end of the reaction (6 to 8 hours) is measured by the evolution of the pH taken on a sample of the reaction mixture. When the reaction is complete (pH less than 10), add purified water by reverse osmosis, distillation or demineralization so as to obtain a total mass of reaction mixture of 50 117.6 kg. The product thus obtained can be used as is or perfumed with essential oils or any perfume commonly used in soap. The addition to the previous reaction mixture of bay laurel soap provides the liquid form of Aleppo soap. 55 3
