Definitions
- the invention relates to the field of methods for extracting active compounds from raw materials of natural origin, making it possible to obtain active extracts used in the formulation of cosmetic, pharmaceutical or food compositions.
- Natural extracts obtained in particular from plants, algae, biomass or beehive products, have been used traditionally for a long time in the cosmetic, dermo-pharmaceutical, pharmaceutical or food fields. Many extraction methods are traditionally used to obtain these extracts: hydro-distillation, extraction with organic solvents, hydroglyco maceration, hxiviation, decoction, ...
- This technology makes it possible to obtain very high quality extracts, tailor-made, according to the choice of operating parameters.
- the solvent power of supercritical CO 2 varies as a function of the pressure and the extraction temperature. Oils rich in polyunsaturated fatty acids or fractions rich in unsaponi iable of very high quality are thus obtained by this technology.
- the disadvantage of supercritical CO 2 extraction is the high cost linked to the low solvent power of pure CO 2 , which limits its application to a few niches.
- a co-solvent such as ethanol, methanol or acetone can be added to the supercritical CO 2 .
- the solvent power of supercritical CO 2 can then be increased by a factor of 10.
- the main objective of the present invention is to propose a new method of extraction with supercntic CO 2 which does not have the above-mentioned drawback.
- the objective of the present invention is also to propose such a simpler method than the methods of extraction by supercritical fluid of the prior art.
- the invention which relates to a process for the extraction by supercritical fluid of one or more active compounds intended to enter into the formulation of a cosmetic, pharmaceutical or food composition containing at least one excipient, from a raw material, said method comprising the steps of; bringing said raw material containing the active compounds into contact in the presence of at least one extraction fluid in the supercritical state comprising CO 2 and at least one co-solvent, - separating said extraction fluid containing at least part active compound (s); causing the CO 2 contained in the extraction fluid to vaporize in order to obtain an extract consisting of said co-solvent and of said part of the active compound (s); - recovering said extract constituted by the co-solvent / compound (s) act ⁇ f (s) mixture; characterized in that, said co-solvent consists of said excipient.
- the present invention is therefore based on the discovery that certain excipients compatible with cosmetic, dermo-pharmaceutical, pharmaceutical or food use can be used in admixture with supercritical CO 2 .
- This mixture then behaves like a fluid whose solvent power can be adjusted by modifying the proportion CO 2 / exc ⁇ p ⁇ ent or by adapting the pressure and the extraction temperature.
- the invention therefore uses the properties of superc ⁇ tic fluids or pressurized liquids, to which an excipient has been added, and having, under appropriate temperature and pressure conditions, an increased dissolving power with respect to the active agents to be extracted. , better selectivity while considerably limiting the risks of degradation of the active compounds, these being protected during the extraction process
- the excipient-active mixture can moreover correspond to the final formulation, which constitutes an important advantage.
- the method according to the latter comprises an additional step consisting in recycling the vaporized CO 2 , at the head of the process where it can be condensed, pumped and reheated so as to be passed back to the supercntic state .
- the method comprises a preliminary step consisting in adding said excipient to CO 2 in the supercritical state to obtain said extraction fluid.
- the method comprises a preliminary step consisting in adding said excipient to the liquid CO 2 under pressure and then heating the mixture obtained in order to pass the CO 2 to the supercritical state and to obtain said extraction fluid.
- said extraction fluid has a compressed temperature between approximately 31 ° C. and approximately 100 ° C. and a compressed pressure between approximately 7.4 MPa and approximately 50 MPa.
- excipients which can be used within the framework of the present invention can be any compound or mixture of compounds compatible with cosmetic, dermo-pharmaceutical, pharmaceutical or food use having sufficient solubility in CO 2 under pressure.
- glycerol an excipient conventionally used in cosmetics, which is considerably insoluble in CO 2 , cannot be chosen while other compounds having a low but not zero solubility can be validly used.
- said excipient is chosen from the group consisting of, propylene glycol, butylene glycol, polyethylene glycols of all molecular weights, monoethyl ether diethylene glycol, hexvlene glycol, polyols, glycemic fatty substances, non-glycemic fatty substances, esters, waxes, silicone oils and terpec compounds.
- the method according to the invention is implemented with weight proportions (raw material) / (CO 2 ) / (Exc ⁇ p ⁇ ent) of (10) / (10 to 2000) / (l to 200).
- the invention also relates to any extract obtained by a single extraction process characterized in that it consists of one or more active compounds and by at least one excipient used in the formulation of a cosmetic, pharmaceutical or food product.
- the extracts obtained by the process which is the subject of the present invention can be used in any galemic form used in cosmetics or dermopharmaceuticals: oil in water and water in oil emulsion, shampoos and conditioners, milks, lotions, gels, ointments, hair sprays , without this list being exhaustive. They can also be used in the food and pharmaceutical fields.
- extracts obtained by the process which is the subject of the present invention into cosmetic vectors such as liposomes, chylomicrons, macro, micro and nanoparticles, as well as macro, micro, nanocapsules. They can be absorbed on powdery organic polymers, talcs, bentonites and other mineral supports.
- the extracts obtained by the process which is the subject of the present invention can be combined in cosmetic compositions with any other ingredient usually used in cosmetics and dermopharmaceuticals: lipids, polymers gelling agents and viscosants, surfactants and emulsifiers, hydro or liposoluble active ingredients, extracts from other raw materials.
- compositions containing the extracts obtained by the process which is the subject of the present invention are intended for all cometic and dermopharmaceutical applications, namely in particular: care and hygiene of the skin, scalp, hair, mucous membranes, oral regions, for anti-aging treatments and sun protection, for hydration, smoothing effect or any other application.
- the present example constitutes a comparative example between the traditional extraction with supercritical CO 2 and the extraction, according to a variant of the process which is the subject of the present invention, of ginger extract.
- the extraction with supercritical CO 2 is carried out without co-solvent at 300 bar and 50 ° C.
- 9 g of extract are collected by percolating 6 kg of CO 2 on 30 g of ginger previously ground and 11 g of extract are collected by percolating 12 kg of CO 2 .
- the extract obtained pasty and "sticky" has a strong odor and flavor, characteristic of the raw material, while the residue is almost deodorized.
- the process is then carried out under the same pressure and temperature conditions but in the presence of a co-solvent, namely propylene glycol, in mixture with CO 2 at a rate of 10 g per 1 kg of CO 2 .
- a co-solvent namely propylene glycol
- the product obtained thanks to the invention contains as an excipient the co-solvent and therefore has a fluid appearance, which makes it much easier to handle and formulate in a food preparation.
- the traditional extraction with supercritical CO 2 of paprika powder is compared with the extraction according to a variant of the process which is the subject of the present invention.
- the extract yield is very low, even for large quantities and percolated CO 2 .
- the same color yield is achieved for 25 kg of CO 2 propylene glycol mixture for 1 kg of paprika.
- the extract collected by decantation, including the co-solvent has a color yield of more than 200,000 UC, without the need to evaporate the co-solvent.
- the traditional supercritical CO 2 extraction of parthenoid from Tanacetum parthenium is compared to the extraction according to a method of the process which is the subject of the present invention.
- 14.8 g of dark green extract and resinous appearance are collected by percolating 8 kg of CO 2 on 300 g of ground drug.
- the extract analyzed by Gas Chromatography has a 14.5% parthenoid content.
- the raw extract In order to increase its conservation and allow the formulation of this extract in soft capsule, the raw extract must be diluted with a glyceride oil.
- the extraction was carried out by adding to the CO 2 0.5% of a mixture of triglycerides of capric and caprylic acids. By percolating 6 kg of this mixture successively on 300 g of drug and then 1 kg of pure CO 2 , 40.5 g of weakly colored oily extract are collected. This extract titrating 5.5% (m / m) of parthenolide, it can be formulated as it is and packaged in soft capsule.
- EXAMPLE 7 In this example, the traditional extraction with supercritical CO 2 of Calendula flowers is compared with the extraction according to a variant of the process which is the subject of the present invention.
- Example 7 is a variant of Example 7 for which part of the water contained in the Calendula flowers is co-extracted.
- the extract then offers the appearance of an emulsion whose properties are of interest in dermo-pharmaceutical and cosmetic preparations.
