Definitions
- the present invention relates to a composition for a long-term cosmetic and / or pharmaceutical treatment of the upper layers of the epidermis by topical application to the skin.
- oils which are active by themselves and / or which contain an active ingredient.
- These oils can be used as is; they are most often in the form of a water in oil or oil in water emulsion. They can also, in known manner, be applied in a form encapsulated in microcapsules of gelatin or other polymers which are crushed on the skin to release the oils, these microcapsules having, in general, dimensions between 5.10 A and 2.106 nanometers (see, for example, US-A 4,976,961).
- the oils applied remain mainly on the surface of the skin where they can be quickly eliminated by simple rubbing, for example, in contact with clothing, or by washing.
- colloid particles are known under the name of nanoparticles, which have much smaller dimensions than micropar ⁇ ticles, since their size is, in general, of the order of 10 to 1000 nm; in these nanoparticles, an active principle is trapped by encapsulation and / or by adsorption and / or absorption (see J. Keuter, J. microencapsulation 1988 Vol 5, pages 115-127).
- nanoparticles is generic and covers, on the one hand, nanospheres and, on the other hand, nanocapsules; the term “nanospheres” denotes the nanoparticles constituted by a porous poly-eric matrix on which the active ingredient is absorbed and / or adsorbed and by the term “nanocapsules” the nanoparticles constituted by a polymeric membrane, which surrounds a core formed by the active principle.
- the polymers which can be used for the manufacture of nanocapsules can be, in known manner, either biodegradable materials or non-biodegradable materials.
- the active agents have a prolonged action over time, without it being necessary to renew the application too frequently. This is the case, for example, for the protection of the skin with sun filters, for the direct coloring of the skin with dyes or pigments and for the treatment of the skin with deodorant, humectant or sensor agents free radicals.
- compositions containing nanocapsules could be obtained, in which the active agents have a prolonged action over time, by using nanocapsules of non-biodegradable polymer.
- the subject of the present invention is therefore a composition for a cosmetic and / or pharmaceutical treatment of the upper layers of the epidermis by topical application to the skin, each application preferably having to have a prolonged effect over time, characterized in that it comprises, in a suitable vehicle, nanocapsules made of non-biodegradable polymer (s) encapsulating an oily phase containing at least one active oil and / or at least one active in an oil active, the nanocapsules having dimensions between 100 and 1000 nm, preferably between 200 and 800 nm.
- At least one of the active agents is preferably chosen from those which must have a long-lasting cosmetic and / or pharmaceutical action on the skin. It in- tends "long-acting" as a persis ⁇ activity for at least an hour.
- the nanocapsules having dimensions between 100 and 1000 nm are sufficiently small to be able to slip between the most superficial corneocytes of the stratum corneum, without however reaching the living epidermis.
- the nano ⁇ capsules therefore penetrate into the first poorly joined layers of the stratum corneum and thus escape the risks of rapid elimination of the surface of the skin by simple rubbing. They will naturally be eliminated as the normal scaling of the skin progresses.
- the weight of the nanocapsules loaded with an oily phase used advantageously constitutes 0.1 to 20% of the total weight of the composition and preferably 0.5 to 10% by weight.
- non-biodegradable polymers polymers forming membranes of nanocapsules which are not degraded by the enzymes of the skin. These membranes, depending on the choice of polymer, can be semi-permeable.
- the membranes of the nanocapsules according to the invention must also be very resistant to their environment after formulation of the composition, whether this environment is aqueous or oily.
- organopolysiloxanes including polydimethylsiloxanes
- the nanocapsules obtained generally have a transparent membrane. Under these conditions, it has been observed that the direct dyes of the skin and the sunscreen filters can respectively play their role in coloring or protecting the skin without being released from the nanocapsules. It has been found that, despite a discontinuous distribution of the sunscreen filter or of the dye, a continuous effect is obtained, that is to say, uniform protection or coloring of the skin. Insofar as the membrane is semi-permeable, it allows exchanges of water or humidity with its environment. Consequently, if the nanocapsules contain a humectant as an active ingredient, it will be able to fulfill its function and moisturize the skin.
- the membrane may be semi-permeable under the action of sebum
- bactericidal agents, deodorants and antiseborrheic agents can be encapsulated in the nanocapsules. They will be released over time under the action of sebum.
- the oily phase encapsulated in the nano ⁇ capsules may contain an active oil.
- This oil can in particular be a UVA and / or UVB sunscreen filter, for example, based on ethylhexyl p-methoxycinnamate (sold under the name "PARSOL MCX”) or 4-tert-butyl-4-methoxy-dibenzoyl ethane ( sold under the name "PARSOL 1789”), and / or a bactericidal and / or fungicidal essential oil, such as thyme oil, an oil with humectant activity such as pentaerythritol tetraethyl-2 hexan ⁇ ate and an oil with anti-radical activities free such as alph -tocopherol.
- PARSOL MCX ethylhexyl p-methoxycinnamate
- PARSOL 1789 4-tert-butyl-4-methoxy-di
- the non-active carrier oils are preferably chosen from simple or modified triglycerides, in particular by oxyethylenation, volatile silicone oils and mineral oils.
- the active agent is preferably an oleophilic active agent which dissolves in the oil. However, it can also be in the form of a dispersion, suspension or emulsion. According to the invention, in the oily phase, it is possible to introduce at least one non-oily active ingredient into a carrier oil and / or into an active oil.
- This active ingredient can be a humectant such as hyaluronic acid, orotic acid, or a lipoprotide, an anti-acne, a liporegulator such as an extract of Centella Asia or ga ma- orizanol, an anti-aging agent such as vitamin A pal itate, a dye, a pigment, an emollient such as an isopropyl ester, a keratolytic agent such as retinoic acid or n -octanoyl 5 -salicylic acid .
- a humectant such as hyaluronic acid, orotic acid, or a lipoprotide
- an anti-acne such as an extract of Centella Asia or ga ma- orizanol
- an anti-aging agent such as vitamin A pal itate
- a dye such as an isopropyl ester
- a keratolytic agent such as retinoic acid or n -octano
- the composition may also contain nanocapsules of biodegradable polymer (s) encapsulating an oily phase containing at least one active which, preferably, has an immediate action after application. It is thus possible to obtain a composition containing both an active agent (s) with immediate action and an active agent (s) with prolonged action.
- compositions according to the invention can be in the form of serum, lotion, aqueous, hydroalcoholic or oily gel, water-in-oil or oil-in-water emulsion, aqueous dispersions of lipid vesicles consisting of ionic lipids or nonionic or a mixture of the two (mixed vesicles); these vesicular dispersions may also optionally include an oil dispersed according to the teaching of FR-A 2 485 921.
- the composition may also contain cosmetically acceptable and / or pharmaceutically acceptable adjuvants, which form the vehicle for the composition after formulation.
- adjuvants mention may be made of fatty substances, oils, petrolatum, preservatives, thickening agents, dyes and perfumes.
- the nanocapsules according to the invention are preferably prepared in a known manner by the method by precipitation of preformed polymers from H. Fessi and JP. Devissaguet described in EP-A 0 274 961.
- the nanocapsules are obtained by precipitation of the polymer around a dispersion of oily droplets by injecting into an aqueous phase containing or not one (or more) surfactant (s), a mixture consisting of (the) oil (s) to be encapsulated, at least one polymer and at least one solvent, then evaporating the solvent. If desired, all or part of the solvent is removed so as to obtain a colloidal suspension of determined concentration in nanocapsules or to obtain, after addition of stabilizing substances, a powder of nanocapsules.
- surfactant s
- 125 mg of ethylene oxide and propylene oxide condensate are dissolved in the proportion by weight 20/80, by weight average molecular weight 1750 and 8350 respectively, marketed under the name "PLURONIC F 68" by the company BASF, in 50 ml of demineralized water, with stirring given by a magnetic bar rotating at 400 rpm.
- the dispersion of nanocapsules obtained is then transferred to a 250 ml round flask which is placed on a rotary evaporator, and the alcohol and part of the water are evaporated until 10 ml of a dispersion is obtained.
- the mean diameter and the polydispersity (PI) are measured with the "nanosizer” (Coulotron granulometer).
- the IP index is evaluated on a scale of 0 to 9, 0 corresponding to an almost perfect homogeneity of the particle size and 9 indicating a high ratio between the size of the largest particles and that of the smallest.
- the polymers and active agents used, as well as the average diameter and the polydispersity of the nanocapsules obtained are given in Table I below.
- composition A containing a sunscreen filter
- composition B containing the same sunscreen filter encapsulated in nanocapsules.
- Composition A A:
- Composition B is a composition of Composition B:
- the two compositions were applied regularly to the back of ten subjects at a rate of 2 mg / cm.
- the skin is then subjected to UVB radiation 15 to 20 min after application of the compositions.
- An opaque plate with circular openings 15 mm in diameter is placed on the area to be exposed. These openings are closed one after the other at determined intervals so as to have areas of skin which have received different doses of radiation.
- the protection index is the ratio of the MED in the presence of the product tested and the MED in the absence of sunscreen product.
- composition according to the invention has led to a significant increase in the protection index for the same concentration of sunscreen filter.
