Definitions
- TITLE Process for obtaining a composition of algae metabolites for cosmetic use, extracts and compositions resulting from such a process and cosmetic use of these extracts and compositions
- the present invention belongs to the technical field of the extraction of plant material for cosmetic purposes, using in particular natural solvents.
- the invention aims to use algae, typically macroalgae, as biological source material, and to extract targeted active products therefrom, usable in the cosmetic industry, from extraction solvents themselves belonging to to green chemistry.
- algae include interesting metabolites and constituents, such as phlorotannins, mannitol, polysaccharides consisting in particular of sugars such as glucose or fucose or even hydrophobic compounds such as for example carotenoids and chlorophylls, as well as other active compounds.
- phlorotannins phlorotannins
- mannitol polysaccharides consisting in particular of sugars such as glucose or fucose or even hydrophobic compounds such as for example carotenoids and chlorophylls
- hydrophobic compounds such as for example carotenoids and chlorophylls
- a solvent is a generally liquid substance which has the capacity to solubilize and dissolve molecules without causing chemical modification of these substances, and without modifying itself. More than a hundred tonnes of organic solvents are produced per year worldwide for industry, but most of them do not correspond to the principles of green chemistry, the aim of which is to obtain safe, clean and energy efficient chemical processes. Among these principles of green chemistry, we can cite the use of less toxic solvents and auxiliaries, or the use of renewable raw materials.
- solvents such as hexane, benzene or acetone. All of these solvents hardly respect these principles of green chemistry. These synthetic solvents, due to their petrochemical sourcing, are the subject of controversies among scientists and the general public. They also have the disadvantage of being volatile, having low selectivity and having a restricted polarity range. Although certain solvents are considered non-toxic, such as water, ethanol or more broadly alcohols, such as glycerol, propylene glycol or butylene glycol widely used in the cosmetic field, these are not always effective in optimally extracting less polar molecules.
- hydrophobic solvents such as caprylic/capric triglyceride or even sunflower oil, widely used in cosmetics, do not have optimal extraction efficiency for plant metabolites.
- neoteric solvents are widely developed to replace traditional solvents. These alternative solvents, in addition to improving selectivity and broadening the polarity range, are used to reduce the toxicity, volatility and dangerousness of solvents, and thus respect the principles of green chemistry a little more.
- Deep Eutectic Solvents belong to these new solvents. These are sustainable solvents derived from renewable resources, which are easy to prepare, without a purification step. They are generally composed of two or three constituents capable of associating together via hydrogen bonds. They are generally described as the mixture of at least one acceptor and one hydrogen bond donor that has a certain stoichiometry will form a eutectic, thus giving a lower melting point to the mixture than to each of the constituents. When the constituents of these solvents are compounds naturally occurring in nature, such as the primary metabolites of plants, they are called NaDES (“Natural Deep Eutectic Solvent”).
- the invention aims precisely to use these DES solvents to extract algae metabolites for cosmetic use.
- NaDES are in fact natural solvents advantageously presenting a strong extraditing power: they would also be present in nature for the survival of species in extreme conditions, and would allow the storage and transport of molecules not soluble in water, or when there is little water.
- These innovative and effective solvents which generally eliminate the need for preservatives, are still little used in cosmetics.
- the inventors have discovered that their use as an algae extraction solvent makes it possible to obtain cosmetic active extracts, which can be integrated into various cosmetic compositions.
- patent application FR3036618A1 published by Gattefossé in December 2016 deals with extraction processes carried out from plant material, and the use of so-called “green” solvents, prepared from biosourced, biodegradable and non-toxic molecules.
- This application proposes to produce plant extracts by extraction with NaDES.
- the NaDES mentioned in this previous document are capable of extracting plant metabolites from their seeds, leaves, fruits, flowers and/or bulbs.
- the only plant cited and tested in this prior patent document is the flower Calendula officinalis.
- This prior patent document also proposes to use the plant extracts produced in the production, for example, of cosmetic compositions. But these NaDES are not disclosed as being capable of extracting algal metabolites.
- patent application FR3034626A1 published by Naturex in October 2016 deals with NaDES to extract plant, animal, or even prokaryotic biological material.
- the plant extracts produced can be integrated into all kinds of compositions, such as cosmetic compositions, but also many other compositions of the food, nutraceutical, pharmaceutical, oenological type, or even perfumes.
- this document proposes to extract natural biological compounds with very specific NaDES, which include betaine.
- These NaDES have been tested to extract biological metabolites from plants, such as cherry blossoms, saffron, samphire, Jericho rose, rosemary, and even olive leaves.
- these betaine-based NaDESs are not discussed, or even disclosed, as being capable of extracting algae metabolites.
- patent application WO2011/155829A1 published by the University of Leiden in December 2011 deals with a process for extracting biological material, for use in the cosmetics industry, but also in many other industries , such as those of food, pharmacy, or even agrochemicals.
- this application proposes to extract biological material with either NaDES or ionic liquids.
- NaDES and ionic liquids are disclosed to be suitable for the extraction of metabolites from many types of materials, such as plants (vanilla, Taxus plant, Artemisia plant, Papaver plant, etc.), insects , animals, or even microorganisms. In particular, extraction from red rose flowers was tested.
- the NaDES presented in this document are not discussed, or even disclosed, as being capable of extracting algal metabolites.
- a first object of the present invention consists of implementing in a new way extraction processes applicable to algal resources, and adapted to obtaining extracts for cosmetic use, using NaDES type solvents.
- Another objective of the invention is to select from DES type solvents extraction solvent formulas which respect the principles of cosmetics and cosmetic regulations and which are more effective, in particular in terms of yield. extraction of active ingredients, selectivity of these active ingredients, stability of the extracted molecules, and/or which make it possible to do without preservatives.
