Gardenia extract for coloring keratin fibers
The present invention relates to the use of an extract of Gardenia intended to color keratin fibers, in particular the hair.
Among the methods for coloring hair, mention may be made of oxidation or permanent coloring. This staining mode uses one or more oxidation dye precursors, usually one or more oxidation bases optionally associated with one or more couplers.
These oxidation bases are colorless or weakly colored compounds which, associated with oxidizing products, allow access, by a process of oxidative condensation, to colored species which remain trapped inside the hair fiber.
When using an oxidative hair dye, the first agent and the second agent are mixed immediately before application and the mixture is applied to the hair. During the application of the hair coloring agent to oxidation, the oxidation dye penetrated into the hair is polymerized by oxidation in the hair so as to generate a voluminous indoid dye and the indo dye develops. Indo dye is not easily removed from the hair due to its size, which ensures excellent color retention of dyed hair and a wide variety of shades. However, it is known that oxidation dyes can cause skin disorders. In addition, it has been pointed out that oxidation dyes are endocrine disruptors that negatively affect an ecosystem, and also that they have reportedly produced cancer, allergies and the like.
The colored and coloring molecules can also be natural compounds derived from plants or trees. It is however difficult to envisage all the dye nuances. There is therefore a real need to develop hair color from natural products.
Unexpectedly, the inventors have found that an extract of gardenia could be useful for coloring keratin fibers, especially human fibers.
Native to China and Japan, Gardenia jasminoides J. Ellis is a shrub of the Rubiaceae family with evergreen foliage, about 1 to 2 m tall generally. This plant is grown in hot and humid tropical countries. The leaves, dark green, are opposite, elliptical to oval-oblong, 5 to 10 cm long and 2 to 7.5 cm wide, cuneiform at the base and acute or acuminate at the apex with a short petiole and with stipules welded in pairs. The white to ivory flowers are bell-shaped, 3 to 4 cm, solitary, terminal, sessile and very fragrant. The fruit is a tough berry with 5 ribs, 1 to 1.5 cm long, ovoid or ellipsoid, surmounted by the persistent calyx, yellow to red at maturity and containing many seeds. The ripe fruit, harvested in autumn and dried, is listed in the Chinese Pharmacopoeia.
Chinese medicine prescribes Gardenia fruit under different preparations: dried fruit (Zhi-zi), fried fruit (Chaozhi-zi) or charred fruit (Jiaozhi-zi). For internal use, it is prescribed as an antipyretic, against bacillary dysentery, pulmonary and urinary infections, hepatitis or as a hemostatic in nasal hemorrhages caused by fever and in external use to treat wounds, eye inflammation, bruises , sores and boils. In Japanese Kampo medicine the fruit is used to treat pain, lung conditions and jaundice. These traditional uses can be explained by the pharmacological properties of the fruit which is hemostatic, anti-inflammatory, stimulant, cholagogue, emetic and diuretic.
The other parts of Gardénia jasminoides have multiple virtues. The febrifuge leaves are crushed in Malaysia to make poultices to treat migraines, pulmonary inflammations. The bark, feverish and tonic, is used in case of fever, dysentery and abdominal pain. In India, the root is used in dyspepsia and in nervous disorders. The emollient flowers are useful for treating ophthalmia, gonorrhea and vaginitis. The seeds are used externally as a paste to treat jaundice, rheumatism, diverticulosis.
In addition to these medicinal uses, fruits are also used to color foodstuffs or textiles of yellow to orange color because of their richness in crocines, pigments identical to those of saffron.
The main compounds of the fruit are:
> iridoids, mainly represented by the geniposide and gardenenoside. The other iridoids present as well as the following compounds in lower quantities: 6-O-transsinapoylgenipin gentiobioside, 6-0-trans-p-coumaroylgenipin gentiobioside, 6-O-trans-cinnamoylgenipin gentiobioside, 6-Otrans-p-coumaroylgeniposide, acid 6 '-O-trans-pcoumaroylgeniposide, 10-O-succinoylgeniposide, 6'-Oacetylgeniposide, Gardenal-I, Gardenal-III, Gardenal-III, 6-βhydroxygeniposide, 6-o-hydroxygeniposide, 6-omethoxygeniposide, feriposide lp-gentiobioside, shanzhiside and lamalbidic and picrocrocinic acids.

The following examples illustrate the invention without limiting its scope.
EXAMPLE 1 Preparation of the Gardenia Extract
The whole fruit from Gardénia is extracted at 90 ° C with water for 2 hours. After solid / liquid separation, pectinases are added. The filtrate is concentrated on water q.s.p. 40% of dry extract, sterilized then dried in the microwave.
The dry aqueous extract obtained is a red powder. The yield is about 25%. The crocin contents are between 0.1 and 10%, the average crocin content is of the order of 2%.
Gardenia fruits are preferably extracted with water or a mixture of water and an organic solvent, an alcohol such as ethanol or an ester such as acetone. The extraction can be carried out on whole fruit or roughly crushed beforehand. The addition of enzymes, such as pectinases to improve filtration can be carried out. The extraction can be carried out by a conventional method known to those skilled in the art, in a reactor, by ultrasound or also by subcritical water or by microwaves at a temperature between 20 ° C. and 100 ° C. depending on the presence or not. enzyme. After solid-liquid separation, the filtrate is used as it is or concentrated preferably up to 2 volumes of water for 1 part of plant involved, and is preferably sterilized. It can then be dried as it is (ie without a drying medium) by conventional methods (paddle dryer, freeze-drying or microwave or atomization) or on a drying medium, such as maltodextrin or silica. The use of maltodextrin allows better handling. The dry aqueous extract thus obtained is a red powder. The yield is about 25%. The production of 1 kg of extract requires the use of 4 kg of gardenia fruit. The crocin contents are between 0.1 to 10%, the average crocin content is of the order of 2%. As these molecules are sensitive to heat, the drying temperature is high and must be below 80 ° C at atmospheric pressure.
