Definitions
- the present invention relates to the field of emulsions and more particularly proposes stable emulsions comprising a mixture of a hydrophilic solution and a hydrophobic solution, in particular emulsions in which the hydrophobic phase comprises at least one vegetable oil and at least one oil.
- the hydrophobic phase comprises at least one vegetable oil and at least one oil.
- 6,416,748 proposes, for example, the use of a crosslinked polymer of at least one ethylenically unsaturated monomer
- the patent FR2750327 proposes using a crosslinked and neutralized poly (2-acrylamido-2-methylpropane sulfonic acid).
- These solutions are thus based on the use of large molecules, which stabilize the emulsion by structuring that they impose on their environment.
- the patents FR27221 16 and FR2720644 propose, for their part, examples of use of solid particles which ensure the dispersion of one of the two phases in the other. These particles also have the advantage of offering product textures that are more advantageous for the consumer.
- cationic surfactants are irritating (especially for the eyes) and toxic to the environment.
- Anionic surfactants the most used because they are good detergents and they foam well, easy to rinse, are generally irritating, although softer than cationic.
- nonionic surfactants with low foaming power, often used as emulsifiers or thickeners, are suspected for some of them (ethoxylated alcohols, alkanolamides, ethoxylated alkylphenols) to be disrupters of the hormonal system.
- compositions consisting of a stable emulsion over time.
- these compositions are stable in the absence of stabilizing molecules (surfactants, gelling agents, etc.) and possess particular properties which give them a competitive advantage.
- the inventors have shown that the absence of surfactant molecules allows optimal activity of the active ingredients.
- These compositions can be broken down into different innovative products because of both an advantageous texture (emulsion without surfactant) and particularly effective active princeps (not inhibited by surfactants), for example:
- the present invention relates to novel compositions consisting of an emulsion of two immiscible phases, in particular a hydrophilic phase and a hydrophobic phase. These compositions constitute stable emulsions even though this stability should not be observed in view of the surfactant levels they contain. In particular, the mixtures contain small amounts of surfactant, or even no surfactant. These emulsions are obtained using the method using high frequency ultrasound, as described in the patent application WO2010 / 149668.
- the subject of the invention relates to an emulsion-type composition
- an emulsion-type composition comprising a mixture of a hydrophilic solution and a stable hydrophobic solution in the absence of surfactant, characterized in that it is obtained by an ultrasonic treatment of which the vibration frequency is greater than or equal to 1 MHz.
- the invention relates to a composition of emulsion type, stable in the absence of surfactant, comprising a mixture of at least one hydrophilic solution and at least one hydrophobic solution, said hydrophobic solution comprising at least one oil plant and at least one essential oil, characterized in that it is obtained by an ultrasonic treatment whose vibration frequency is greater than or equal to 1 MHz.
- the emulsion-type composition according to the invention consists of a mixture of a hydrophilic solution and a hydrophobic solution, stable in the absence of surfactant.
- An emulsion is a mixture, macroscopically homogeneous but microscopically heterogeneous, of two immiscible liquid substances.
- the term "emulsion” refers to a mixture of a hydrophilic phase and a hydrophobic phase.
- compositions according to the invention may be of the oil-in-water emulsion or water-in-oil type, depending on the relative amounts of the components.
- compositions according to the invention are formulated without surfactant.
- a composition is said to be “without surfactant” or “stable in the absence of surfactant” if it does not contain surfactant, emulsifier, or other substance or particle in an amount such that it allows to stabilize the preparation vis-à-vis the phase separation.
- surfactant will be used to designate generally any component having a stabilizing action on the emulsion.
- hydrophilic phase used to prepare the emulsion can be diverse. It may for example be water of various qualities (demineralised, purified, etc.), plant extracts, vegetable aqueous macerates, infusions, hydrolates, including vegetable hydrosols, vegetable waters from fruit or plants, juice, or a mixture of all or part of these products.
- the hydrophilic phase may also contain one or more water-soluble compounds.
- hydrophobic phase used to prepare the emulsion
- hydrophobic phase can be diverse. It may for example be vegetable oils, namely pure vegetable oils or extracts of vegetable oils, oily macerates or infusions in oils. It may also be essential oils, mineral oils, waxes, synthetic raw materials or perfume raw materials such as absolutes or concretes.
- the hydrophobic phase may also consist of a mixture of all or part of these products and may contain one or more liposoluble compounds.
- the hydrophobic solution comprises at least one vegetable oil and at least one essential oil.
- Alcohols may also be incorporated into certain compositions of the invention. They may be of hydrophilic or hydrophobic nature depending on the length of their carbon chain and the nature of the groups they carry.
- Emulsions excluding any texturizing agent are liquid. So as to facilitate handling and use, gelling agents may be added without this denatures the emulsion, including its properties.
- the compositions according to the invention may contain gelling agents, preferably of natural origin, such as xanthan gum or alginates.
- the gelling agents will act primarily on the texture of the composition, which will depend on the amount added.
- the proportion of gelling agent will generally be less than 0.1%, preferably equal to 0% of the composition.
- the proportion of gelling agent will generally be between 0.1% and 0.8% of the composition.
- the proportion of gelling agent will generally be between 0.8% and 2% of the composition.
- the proportion of gelling agent will generally be between 2% and 5% of the composition.
- the gelling agents are added after emulsification according to the desired texture.
- the pH of the products obtained after emulsification is generally between 6 and 7, preferably equal to 7. It is possible to add, if necessary, an acidity corrector to adjust the pH of the composition as close to that of the need. .
- the pH may for example be adjusted to a value of less than 5 to improve the preservation or adjusted as close as possible to that of the skin for creams for topical use.
- this addition may take place either during the emulsification process or at the end of the process.
- the fact of having a stable emulsion at neutral pH has an advantage in the choice of preservatives. Indeed, the most used preservatives are effective only at acidic pH, for example at pH 5.5 for potassium sorbate. However, these preservatives, especially potassium sorbate (E202) may have irritating effects on the skin, eyes and respiratory tract and have some toxicity; studies are underway to determine the degree of dangerousness of this product. In this context, it is interesting to be able to offer formulations containing preservatives of natural origin having a better tolerability, such as cosgard or leucidal, which are effective at neutral pH. Thus, the compositions of the invention have the advantage of being stable, effective and compatible with the use of preservatives of natural origin. An example of such a composition is described in Example 1 which describes a shampoo with very interesting properties for the hair while having a neutral pH, which is both surprising and innovative.
- antimicrobial products and / or antioxidants For better preservation of the compositions over time, it may be necessary to add antimicrobial products and / or antioxidants. For example, it is important in cosmetics applications to avoid the rancidity of HV, which can become comedogenic.
- the percentage of antimicrobial products and / or antioxidants needed varies depending on the activity of the product itself and the composition itself.
- the essential oils present in the compositions can naturally play this role of preservatives.
- antioxidants examples include tocopherol (0.2%) and rosemary CO2 extract (0.075%).
- compositions of the invention are numerous and they can differ according to the fields of application and the use that is made of them.
- compositions containing surfactants Due to a simpler formulation, it is possible to prepare natural and healthy compositions having less allergenic risk than compositions containing surfactants.
- the compositions can be 100% organic, in the agri-food and cosmetic fields, for example.
- the inventors also showed that the activity of the active ingredients is preserved in the emulsified compositions without surfactant and that the effectiveness of the compositions (without surfactant) is higher than that of the products with surfactants, in proportion to equivalent active ingredients. Finally, these compositions are stable. Their stability is ensured by the method, thanks to an ultrasonic treatment whose vibration frequency is greater than or equal to 1 MHz, as described in patent WO2010 / 149668. Their stability at room temperature is observed for at least 3 months and up to more than 36 months.
- the composition is an oil-in-water emulsion comprising between 2% and 10% of coco-caprylate, between 2% and 10% of vegetable oil, between 0.1% and 3% of coconut oil. essential oil and between 0% and 85% hydrosol.
- Such a composition can be used as a shampoo.
- such a composition will further comprise between 5% and 30% foaming agents, to satisfy the user waiting for a foam product.
- composition according to the invention comprises apricot kernel oil, atlas cedar essential oil and grapefruit essential oil.
- composition according to the invention comprises vegetable oil of jojoba, vegetable oil of camelina and essential oil of incense oilban.
- composition is an oil-in-water emulsion comprising:
