Description

Extract of Metrosideros and its use as an antimicrobial agent in

  a dermatological or cosmetic composition. The present invention relates to an extract of Metrosideros, its use as an antimicrobial agent in a cosmetic or dermatological composition, the use of this extract as deodorant active agent, preservative agent, active agent intended for the treatment of hyperseborrhea and / or acne and active for the treatment of

scalp conditions.

  It is common to introduce antimicrobial agents into cosmetic or dermatological compositions. Indeed, these antimicrobial agents are especially intended to prevent the development and proliferation of microorganisms in these compositions. Such a development of microorganisms would quickly render these compositions unfit for use. To avoid this development, the compositions must be protected both against the microorganisms liable to develop inside the compositions and against those which the user can introduce into them by handling them,

  especially when gripping products with your fingers.

  These antimnicrobial agents are also used in order to inhibit or regulate the development of a cutaneous bacterial flora, this cutaneous flora degrading in particular sweat and

  thus causing the formation of volatile smelly products.

  The bacterial skin flora is involved, as is well known, in inflammatory skin conditions such as

  acne, scalp conditions or seborrheic dermatitis.

  The bactericidal substances used to reduce, even eliminate generally unpleasant axillary odors, inhibit the development of the cutaneous bacterial flora responsible for these axillary odors. Among the bactericidal products, the most commonly used is Triclosan (5-chloro-2- (2,4-dichlorophenoxy) phenol), which has the drawback of significantly modifying the ecology of the cutaneous bacterial flora, be inhibited by certain compounds, such as, for example, nonionic surfactants, commonly used in the formulation of cosmetic compositions. The insoluble nature of Triclosan in water does not allow its incorporation in

  essentially aqueous formulas.

  In order to obtain long-term efficacy, we are looking for new products which exert an action of deodorant active agent, that is to say products which are capable of modifying, reducing and / or removing or prevent the development of body odors (this definition is given in the book "Cosmetic Science and Technology Series" - 1988 / Volume 7 chapter 10 - Hlic). In addition, we are looking for products that do not have the disadvantages of

  active substances used in the prior art.

  The best known chemical preservatives used as an antimicrobial agent include

  C1-C4 alkyl parahydroxybenzoates, or formalin donors.

  Unfortunately, these preservatives have either the disadvantage of being ineffective or of causing intolerances on human skin, such as irritations and / or allergies, and more especially on sensitive skin. The same is true for alcohols or polyols, such as ethanol or propylene glycol, in particular when they are

  present at relatively high rates.

  Furthermore, it is known to use preservatives in skin cleansing products such as benzalkonium chloride, chloroacetamide or thimerosal. Thus, document WO-A-94/27436 teaches a preservative system comprising a paraben and a quaternary ammonium compound such as benzalkonium chloride or cetylpyridinium chloride. However, the current trend and the related legislation, evolve more and more towards the elimination of these compounds because they are not completely

  free of toxicity or adverse effects.

  It is therefore found that there remains the need for preservatives having an action at least as effective as those of preservatives of the prior art but not having their drawbacks, in particular being non-irritating for the skin or the scalp. Likewise, the active agents intended for the treatment of hyperseborrhea and / or acne, and / or of the scalp affections used until now can be the cause of undesirable effects, in particular irritations of the skin. Thus, we are looking for active ingredients for the treatment of hyperseborrhea and / or acne, or scalp affections, effective and not having these drawbacks. After much research on the subject, the Applicant has surprisingly discovered that extracts of Metrosideros can be used as an antimicrobial agent. It has in particular been found that these extracts have bacteriostatic activity, and thus make it possible to regulate the bacterial flora without qualitatively modifying it. These extracts thus have in particular the property of preventing the development of unpleasant odors, without the drawbacks of the previously active substances

  used in deodorant compositions.

  It has also been observed that these extracts of Metrosideros can be used as a natural preservative and as active agents intended for the prevention or treatment of hyperseborrhea and / or acne, or affections of the scalp. In fact, it has been found that the compositions in accordance with the invention make it possible not only to obtain a rapid improvement in the acne-causing inflammatory state, but also to lead to the reduction of so-called first type lesions with non-inflammatory characteristic as well as to get a

  improved scalp conditions.

  Metrosideros extracts can also be used in oral compositions; these extracts can in particular

  be used as preservatives both in oral compositions -

  anhydrous dental products only in oral-dental compositions

watery.

  The extracts of the invention also have the advantage of being water-soluble in interesting proportions and sufficient to be easily formulated, in particular in the compositions

  water-based cosmetics for human topical application.

  These compositions are also non-toxic and non-irritant. Thereafter, the term "extract of Metrosideros" should be understood as "extract of cells of Metrosideros" and more precisely as "extract of cells of at least one plant of the genus Metrosideros of the family Myrtaceae". Said material can be

  obtained by in vitro or in vivo culture.

  The term “in vitro culture” means all of the techniques known to a person skilled in the art which make it possible artificially

  obtaining a plant or part of a plant.

  By in vivo culture is meant all of the

  culture to obtain a plant or part of a plant.

  Thus, for example, according to the invention, the extract can be an organ extract (root, stem, leaf), or even organ cells, of at least one plant of the genus Metrosideros of the family Myrtaceae, or an extract of undifferentiated cells from at least one such plant. By undifferentiated plant cells is meant any plant cell having none of the characteristics of a particular specialization and capable of living by itself and not in dependence on other cells. These undifferentiated plant cells are possibly suitable, under the effect of an induction, for any

  differentiation consistent with their genome.

  According to the chosen culture method, and in particular according to the chosen culture medium, it is possible to obtain, from the same explant, undifferentiated plant cells having different characters. As plant material which can be used, mention may in particular be made of that from Metrosideros Operculata, Metrosideros Punctata and

Metrosideros Brevestylis.

  The extracts of the invention are in particular purified extracts. Any known method of purification or extraction of

  a person skilled in the art can be used according to the invention.

  Mention may in particular be made of alcoholic extracts, in particular ethanolic extracts and hydroalcoholic extracts. One can also use an extract prepared by the method

  described in French patent application No. 95 02379.

  Thus, in a first step the plant material is ground in a cold aqueous solution, in a second step the particles in suspension are removed from the aqueous solution obtained from the first step, and in a third step the aqueous solution obtained from the second step. This aqueous solution corresponds

to the extract.

  On the other hand, the first step can advantageously be replaced by a simple freezing operation of the plant tissues (for example at -20 ° C.), followed by an aqueous extraction taking up the

  second and third steps described above.

  In a variant of this process, an hydroalcoholic solution is used in the first step and in the third step, the solution is evaporated to dryness, the residue being used as it is or after purification. One can also use the method of extraction by sonification

  described by E.A. MAGEL and Co. 1991. Trees-Tome 5 - 203-207.

  Thus, the subject of the invention is an extract of cells from at least

minus a Metrosideros plant.

  Another subject of the invention is the use of such an extract as an antimicrobial agent in dermatological or cosmetic compositions. Another subject of the invention consists of a composition

  cosmetic or dermatological comprising such an extract.

  Another subject of the invention consists in the use of this extract as deodorant active or antiperspirant active, agent inhibiting the development of odors, preservative, active intended for the treatment of hyperseborrhea and / or acne and as active intended

  treatment of scalp conditions.

  The invention also relates to the use of an extract according to the invention in a cosmetic or dermatological composition for

  limit microbial growth.

  The subject of the invention is also the use of an extract according to the invention for the preparation of a dermatological or cosmetic composition for treating hyperseborrhea and / or

  acne or scalp conditions.

  The following examples and compositions illustrate the invention

without limiting it in any way.

EXAMPLES

  Example 1: Preparation of an extract of Metrosideros Operculata var francii: Stems or leaves of Metrosideros were used

  Operculata var francii Montes Dzumac from Nova Scotia

  Caledonia. These stems or leaves have been previously dried and ground

into a fine powder.

  The powder was extracted with a water / ethanol mixture (40/60 by volume) in an amount of 10 parts per 1 part of plant, at room temperature. After 5 hours of stirring, it was filtered and / or centrifuged; we have

  evaporate the filtrate and / or put the supernatant to dryness.

  The residue was stored under phosphoric anhydride before use. Example 2: In Vitro Odor Evaluation Test An odor absorption test was carried out on natural sweat. The principle of this test consists in adding the antimicrobial agent to the fresh sweat, then to carry out an evaluation

  olfactory after 18 hours and 24 hours incubation at 37 C.

  We therefore took axillary sweats from several human models in a sauna, which we gathered to make a sweat sample. To obtain the characteristic foul odor of sweat, before introducing the active substance, this sweat sample was incubated for 18 hours at a temperature of 37 C. In each bottle of active substance to be tested as well as in a control bottle (without active substance), 1 ml of the incubated sweat sample was introduced and then the active substance was introduced into each of the flasks to be tested. 1) After 18 hours of incubation, the odor of each bottle was evaluated The odor was evaluated on 2 criteria - the overall intensity (rating from 0 to 4)

0 I 1 2 3 4

  none slight moderate strong very strong

  - hedonic appreciation (rating from 0 to 6).

0 1 2 3 4 5 6

  very pleasant pleasant slightly neutral slightly unpleasant very pleasant unpleasant 2) The flasks were incubated again in a 37 C oven for 6 hours, the total desired incubation time being 24 hours. The odor evaluation of each bottle was then repeated

like before.

3) RESULTS:

  The results are given in percentages of variation of the intensity of odor and of the hedonic note compared to the control sweat without antimicrobial agent Antimicrobial agent Amount MA% variation% variation mg / ml of sweat intensity of odor unpleasantness of the odour

I - 18% - 14%

  Metrosideros 2.5 - 55% - 43% -56% o -57% - 44% o- 44% The results demonstrate that the antimicrobial agents of the invention have an important capacity for inhibiting the development of odors from natural sweat for at least 24 hours. In addition, at 5 mg MA / ml of sweat, the odor was perceived as "slightly pleasant". Thus the antimicrobial agent of the present invention not only has the advantage of inhibiting the development of smelly odors but is moreover at the origin

a slightly pleasant odor.

  EXAMPLE 3 Determination of the Microbiostatic Activity The microbiostatic activity of the extract obtained in Example 1 was determined by a conventional method known as MIC (Minimum Inhibitory Concentration), the MIC corresponding to the lowest concentration at which a given product inhibits the

  grows from a given strain under defined conditions.

  In this case, a strain of Corynebacterium xerosis,

  CIP reference 5216 was used.

  The tests were carried out on dry extracts, namely the powder obtained in Example 1, at 5% in ethanol. 100 g of the solution were added to 1.9 ml of agar culture medium in supercooling at 45 ° C. (medium chosen according to the nutritional requirements of the strain studied). After vortexing, successive dilutions, in geometric progression of reason 2, of the solution obtained were carried out using the agar culture medium in supercooling at 45 C. 1 ml of each dilution was introduced into the wells. a microplate (Falcon, 24 wells). 4 g of microbial suspension were deposited at the

surface of the agar medium.

  A control tube was also prepared: ethanol or H20

  0.10 fl + 1.9 ml of culture medium.

  The concentration of the antimicrobial agent from which the growth of the microorganism is completely inhibited (absence of

  middle disorder) is thus determined.

  It has been observed that the growth of Corynebacterium xerosis is blocked at the concentration of 7.8.10-2 mg of dry extract per ml of medium

of culture.
