Abstract
Description
Title of the invention: Oil-in-water emulsion comprising a semiochemical composition, suitable for administration in the form of a mist Technical field of the invention
[0001] The invention relates to the field of semiochemical products and describes, in particular, a composition in the form of an oil-in-water emulsion comprising an aqueous phase and an oily phase comprising a semiochemical composition, particularly suitable for administration in the form of a mist, as well as a method for its preparation. The invention also relates to the non-therapeutic use of the composition according to the invention for administration, in particular by spraying with a mist sprayer, onto the skin of an animal or a human, or onto the skin of farm animals treated in groups, or onto an element of the environment such as textiles and / or objects and / or walls, or by spraying into the air, particularly near the nose of an animal or a human. Prior art
[0002] The semiochemicals according to the invention correspond to mixtures of several chemical compounds, first described in particular by Silverstein, RM (1977). Semiochemicals are chemical substances emitted by a plant or animal that elicit a non-therapeutic behavioral or physiological response in another organism. When the semiochemical affects an individual of the same species (an "intraspecific" semiochemical), it is called a pheromone (Wyatt TD, 2003). There are several types of pheromones that enable different types of behavioral interactions or communication, for example, calming pheromones, sex pheromones, territorial marking pheromones, and alarm pheromones. When the semiochemical affects an individual of a different species (an "interspecific semiochemical"), it is called an allelochemical.Among allelochemical substances, an allomone is an allelochemical substance that triggers a reaction in the target species, this reaction being favorable to the species that releases the allomone (the opposite is a kairomone).
[0003] Since 1995, products whose active ingredients are semiochemical agents have been placed on the market. Some of their uses require application of the product to the animal's skin, for example, to achieve the desired effects on an animal in an open environment or to protect it against pests such as parasites or biting insects, or on human skin. The physicochemical constraints of semiochemical components, particularly their volatility and insolubility in water, have led to the use of excipients such as ethoxydiglycol in commercially available products. The use of this type of excipient is now increasingly restricted by current regulations, as well as by the general public, who tend to reject them due to their synthesis methods and their potential direct and environmental toxicity. It has therefore become necessary to develop aqueous formulations of semiochemical compounds. Presentation of the invention
[0004] The invention aims to develop a composition based on semiochemical products (also referred to as compounds, active ingredients or agents) in a new galenic form, preferably non-toxic and environmentally friendly, in particular in the form of an oil-in-water (O / W) emulsion, preferably in the form of a stable and homogeneous oil-in-water (O / W) emulsion, for administration, in particular by spraying with a mist sprayer, onto the skin of an animal, in particular a mammal, or a human, or onto the skin of farm animals treated in groups, or onto an element of the environment such as textiles and / or objects and / or walls, or by spraying into the air, in particular near the nose of an animal or a human, in particular to reduce and / or avoid obtaining a wetting effect or staining; or to reach the vomeronasal and olfactory mucosa more quickly.Another objective of the invention is to develop a composition based on semiochemical products that is positively evaluated in acceptability tests by the target animals.

Once the mashing was complete, all the water was added. 3. After homogenization of the aqueous phase (obtaining a homogeneous mixture), the aqueous phase was maintained at 70°C and under agitation until step 3. STEP 2: Preparation of the oil phase 4. In another container suitable for receiving the final volume of the oily phase, the oily phase compounds were weighed and added, namely Cremophor GS 32, Eumulgin CO 40, Polysorbate 80 or Polysorbate 20, Myritol 318, Tinogard TT, Aromastat and the semiochemical composition (CS1, CS2, CS3, CS4 or CS5, CS6, CS7, CS8, CS9 or CS 10). 5. Once all the compounds were added, the mixture was stirred and heated to 70°C until a homogeneous mixture was obtained. STEP 3: Formation of the oil-in-water emulsion 6. Once the two phases (aqueous and oily) were perfectly homogeneous, the oily phase at 70°C was added to the aqueous phase at 70°C. Thorough agitation of the emulsion was ensured throughout this step. The emulsion was then cooled to room temperature after homogenization. STEP 4: pH adjustment using only the CS9 composition mentioned above 7. In the case of the composition including the semiochemical composition CS9, and in order to increase the pH, a pH adjustment step was carried out by adding a 10% NaOH solution until a pH between 6 and 7 was obtained. STEP 5: Perfume 8. Addition of any fragrance under agitation at room temperature STEP 6: Recovery of the oil-in-water (O / W) emulsion The final emulsion obtained was fluid, opalescent / transparent, of low viscosity.
[0130] Example 3. Organoleptic measurements of oil-in-water emulsions (mist) according to example 1
[0131] 3 criteria (appearance, color, odor) were selected for organo measurements leptics. Appearance: Free-flowing liquid Color: White or opalescent / transparent / translucent Odor: Characteristic odor.
[0132] Example 4. pH measurements of oil-in-water emulsions (mist) according to example 1
[0133] The pH measurements were carried out using a LE 438 IP 67 electrode marketed by Mettler Toledo®. This is a 2-in-1 glass pH electrode with integrated temperature sensor and liquid electrolyte for rapid laboratory measurements; for aqueous samples, such as acids, bases, etc.
[0134] The specifications of this electrode are mentioned in the following Table 2.
[0135] [Tables2] Measuring range pH 0 - 14 Zero point 7.00 ± 0.25 Temperature range 0 - 80 °C Temperature probe NTC 30 kQ Membrane resistance (25 °C) < 250 MQ Reference electrolyte 3 mol / L KCl solution saturated with AgCl Reference system Ag / AgCl Reference diaphragm Gel
[0136] Before any measurement was taken, the pH meter used was calibrated. Indeed, the nature of the semiochemical composition can affect the pH of the emulsion because some semiochemicals have an acidic pH. For topical application, particularly cutaneous application, it is therefore necessary to measure the pH of each emulsion obtained and, if necessary, adjust the pH to obtain a pH between 5 and 8, preferably between 5.5 and 7.5, or between 6.0 and 7.5.
[0137] pH measurements were carried out after obtaining each emulsion, and are reported below: MIST with CS1: 5.0 < pH < 7.5 MIST with CS2: 5.0 < pH < 7.5 MIST with CS3: 5.5 < pH < 7.5 MIST with CS4: 5.5 < pH < 7.5 MIST with CS5: 5.5 < pH < 7.5 MIST with CS6: 5.5 < pH < 7.5 MIST with CS7: 5.5 < pH < 7.5 MIST with CS8: 5.5 < pH < 7.5 MIST with CS10: 5.5 < pH < 7.5 MIST with CS11: 5.5 < pH < 7.5 MIST with CS9: 3.5 < pH < 4.5.
[0138] In order to get as close as possible to the pH of animal or human skin, and to avoid causing skin irritation, a pH adjustment was made for the formulation corresponding to BRUME with CS9. Following this adjustment, new pH measurements were taken and are reported below: MIST with CS9: 6.0 < pH < 7.5.
[0139] For formulations corresponding to BRUME with CS1, CS2, CS3, CS4, CS5, CS6, CS7, CS8, CS10 and CS11, no pH adjustment step was performed.
[0140] Example 5. Measurement of the viscosity of oil-in-water emulsions (mist) according to Example 1
[0141] Viscosity is the resistance of a fluid to sliding from one layer relative to another.
[0142] For each formulation, the viscosity must be checked after each batch. Viscosity is influenced by several factors, including temperature, the measuring instrument used, the measurement speed, and the time of measurement relative to the batch (measurements at T0 and T+24h, T+48h). Viscosity measurement should be performed when the solution is at room temperature, preferably at T+24h.
[0143] The measurement of the viscosity of the oil-in-water emulsions according to example 1 was carried out using the Brookfield digital viscometer (model DV-I Prime), mobile S 61 (large mobile) and at a rotation speed of 0.6 RPM.
[0144] The Brookfield DV-I Prime viscometer measures the viscosity of fluids at a given velocity gradient. The operating principle consists of rotating a spindle (which is immersed in the liquid to be tested) by means of a calibrated spring. The measurement range (in centipoise or millipascal-seconds) is determined by the rotational speed of the spindle, the size and shape of the spindle, the section in which the spindle is rotating, and the full-scale torque of the calibrated spring.
[0145] The specifications of the Brookfield DV-I Prime viscometer are reported in the Table 3 follows.
[0146] [Table 3]: Speeds (rpm) 0.0; 0.3; 0.6; 1.5; 3; 6; 12; 30; 60; 0.5; 1; 2; 2.5; 4; 5; 10; 20; 50; 100 Viscosity range (cP) 15 - 2,000,000 Operating environment Temperature range 0°C to 40°C (32°F to 104°F) 20% to 80% RH: none Condensation Analog output of the 0-1 Vcc torque (0 to 100% torque) Viscosity measurement accuracy ± 1 °C: - of full scale Viscosity measurement reproducibility 0.2% of full scale Used mobiles S61; S62; S63; S64
[0147] Following these measurements, all the oil-in-water emulsions (mist) according to Example 1 had a viscosity between 1 and 50 cP or mPa.s, with the exception of the emulsion comprising the semiochemical composition CS9 which had a viscosity between 3500 and 8000 cP or mPa.s. The viscosity was notably lower in the presence of a perfume or a NaOH solution (the percentage of water being higher).
[0148] Example 6. Test for identifying the presence or absence of stains following spraying of the semiochemical composition CS9 on different textiles of different materials
[0149] Protocol - Place the garment on a hanger, take a photo before application (T0) - Spray the CS9 semiochemical composition from 20-30 cm away on different areas of the garment [10 sprays per garment, if the garment is in 2 parts (example: trousers) perform 5 sprays per side] - Photo after application (Tl) - Take a photo Ih after application (T2) - Wash the clothes using a washing machine (standard program at 30°C) - Take a photo after washing (T3).
