The invention relates to a method for the solid/liquid extraction of an oil or butter, particularly having a high unsaponifiable content, contained in at least one solid vegetable matter or a micro-organism. The method includes at least the following steps: solid/liquid extraction of at least one solid vegetable matter or a micro-organism using a first solvent system comprising a concentration of solvent selected from among fluorinated aromatic solvents, particularly trifluorotoluene (BTF) and hexafluorobenzene (BHF), tert-butyl ethers, particularly 2-ethoxy-2-methylpropane, also known as ethyl-tert-butyl-ether (ETBE), and 2-methoxy-2-methylpropane or methyl-tert-butylether (MTBE), solvents comprising at least one silicon atom, particularly hexamethyldisiloxane (HMDS) and tetramethylsilane (TMS), methyl-tetrahydrofuran (MeTHF), and mixtures thereof, representing at least 50 vol.-% in relation to the total volume of the solvent system; and, optionally, recovery of a fraction comprising the oil or butter, particularly unsaponifiable enriched. The invention also relates to an unsaponifiable fraction, oil or butter obtained using this method and to compositions containing said oil or fraction.

Solid/liquid extraction

The present invention relates to an extraction process of an unsaponifiable fraction contained in an oil or a vegetable butter, in an oil originating from a micro-organism, in a concentrate of oil or butter or of oil originating from a micro-organism, or in a co-product of the refining industry for vegetable oils, such as deodorization exhaust and distillates of physical refining, or oils originating from micro-organisms, comprising at least:

Liquid/liquid extraction with a solvent comprising at least 5 carbon atoms and 1 or 2 oxygen atoms

The present invention relates to the use of at least one vegetable oil refining industry by-product to obtain a purified total unsaponifiable of vegetable oil cleared of the impurities initially present in the said by-product, advantageously cleared of sapid and odorous compounds and/or chemical compounds resulting from the deterioration and the degradation of vegetable oils. The invention further relates to a method for obtaining a purified total unsaponifiable of vegetable oil from at least one vegetable oil refining industry by-product. The invention further relates to a purified total unsaponifiable of vegetable oil able to be obtained by this method, as well as compositions containing such an unsaponifiable. The invention further relates to such unsaponifiables or such compositions for the use thereof as a drug, medical device, dermatological agent, cosmetic agent or nutraceutical, in humans or animals.

Use of at least one coproduct from the vegetable oil refining industry for obtaining a purified total unsaponifiable vegetable oil product

The invention relates to a composition, such as a cosmetic, dermatological, or pharmaceutical composition, including an extract of the above-ground portions of, advantageously the leaves and, optionally, a suitable carrier. The invention also relates to such a composition or such an extract to be used in the prevention or treatment of disorders or diseases of the skin, mucous membranes, or nails and hair, to be used in the prevention or treatment of vascular disorders and/or problems linked to hyperseborrhea, or further to be used as an anti-ageing, healing, moisturizing, slimming and/or anti-cellulite, anti-allergy and pro-pigmenting product. Finally, the invention relates to a cosmetic care method for the skin, nails and hair, or mucous membranes, with a view to improving the condition or appearance thereof, consisting of administering such a composition or such an extract.

Extract of the above-ground portions of gynandropsis gynandra or cleome gynandra, and cosmetic, dermatological or pharmaceutical compositions including same

The present invention relates to a process for the solid/liquid extraction of a natural extract contained in at least one vegetable solid or micro-organism comprising at least the following steps:

Solid/liquid extraction with a solvent comprising between 5 and 8 carbon atoms and 1 or 2 oxygen atoms

The invention relates to a method for the extraction of all unsaponifiable fraction contained in a vegetable oil, an oil originating from a micro-organism or a vegetable butter or in a co-product from the vegetable oil refining industry, such as deodorization discharge. The method includes at least: A) a step comprising the transformation of the aforementioned oils, butter or co-product from the vegetable oil refining industry or oils originating from micro-organisms into a hydro-alcoholic solution by means of, in particular, a step selected from saponification and esterification steps; B) a step comprising the extraction of the hydro-alcoholic solution in which the fatty fraction is separated from the unsaponifiable fraction by means of liquid/liquid extraction; and C) an optional step comprising the purification of the unsaponifiable fraction, selected from the group containing crystallization and liquid/liquid extraction steps. According to the invention, at least one step from the liquid/liquid extraction steps in step B, the crystallization steps in step C and the liquid/liquid extraction steps in step C is performed using a first solvent system containing a concentration of solvent selected from among: fluorinated aromatic solvents, particularly trifluorotoluene (BTF) and hexafluorobenzene (BHF); tert-butyl ethers, particularly 2-ethoxy-2-methylpropane, also known as ethyl-tert-butyl-ether (ETBE); solvents comprising at least one silicon atom, particularly hexamethyldisiloxane (HMDS) and tetramethylsilane (TMS); methyl-tetrahydrofuran (MeTHF); and mixtures thereof, representing at least 50 vol.-% in relation to the total volume of the solvent system. The invention also relates to the fractions obtained using this method and to compositions containing said fractions.
