Definitions
- the present invention relates to a new cosmetic or dermatological composition
- a new cosmetic or dermatological composition comprising in combination mequinol (or 4-hydroxyanisole) and a depigmenting agent usable by topical application for depigmentation of the skin.
- the composition according to the invention may also contain a sunscreen.
- the pigmentation of the skin results from the synthesis of melanin in the melanocytes of the dermis by the transformation of tyrosine under the influence of a cuproprotein enzyme tyrosinase.
- Mequinol or 4-hydroxyanisole has long been known as a compound having depigmenting activity (Brun R, Journal of the society of cosmetic chemists (1960), 11, 571-9).
- mequinol as a depigmenting agent is to act as a substrate for tyrosinase (Riley P, Journal of Pathology (1969), 97 (2) 1 185-91 and Journal of Pathology (1969), 97 ( 2), 193-206.
- Vitamin C or its derivatives are usually used as antioxidants at concentrations lower than 0.005% of the entire composition, as illustrated in US patent 6,353,029.
- Kojic acid is already known in the prior art as a fungal metabolic with antioxidant properties, which causes contact dermatitis when its use is prolonged.
- Azelaic acid has been reported in the literature as effective in the treatment of melasma, but this activity seems controversial (Sarkar et al., Dermatology 2002, 205: 249-254).
- the invention therefore relates to a depigmenting composition for the skin comprising, in a physiologically acceptable medium, mequinol and at least one depigmenting agent chosen from the list consisting of kojic acid and its derivatives; azelaic acid and its derivatives; dicarboxylic acids; vitamin C and its derivatives, arbutin and its derivatives and paracetamol.
- the depigmenting composition of the skin may comprise, as depigmenting agent kojic acid, azelaic acid or arbutin.
- physiologically acceptable medium means a medium compatible with the skin, the mucous membranes and / or the integuments.
- depigmenting agent means any active agent having a depigmenting activity on the skin. This activity makes it possible to decrease the already existing pigmentation of the skin and also to prevent any additional pigmentation greater than natural pigmentation.
- composition comprising the combination according to the invention makes it possible to obtain a clear whitening of the skin.
- the invention also relates to a depigmenting composition for the skin comprising, in a physiologically acceptable medium, mequinol, at least one depigmenting agent and at least one sunscreen.
- the composition according to the invention advantageously comprises between 0.0001 and 20% by weight of mequinol relative to the total weight of the composition and between 0.025 and 20% by weight of depigmenting agent relative to the total weight of the composition, and preferably, respectively, between 0.001 and 10% by weight of mequinol relative to the total weight of the composition and between 0.05 and 10% by weight of depigmenting agent relative to the total weight of the composition.
- the composition can also comprise at least one sunscreen in preferential concentrations ranging from 0.001 to 30.00% by weight relative to the total weight of the composition.
- sun filters non-limiting examples that may be mentioned include physical sun filters such as titanium dioxide, zinc oxide and chemical sun filters such as octocrylene, ethylhexyl methoxycinnamate, octyl salicylate, avobenzone, oxybenzone, ecamsule or drometrizole trisiloxane, or mixtures thereof.
- physical sun filters such as titanium dioxide, zinc oxide
- chemical sun filters such as octocrylene, ethylhexyl methoxycinnamate, octyl salicylate, avobenzone, oxybenzone, ecamsule or drometrizole trisiloxane, or mixtures thereof.
- the composition may include several sun filters.
- each sunscreen can be added at a concentration ranging from 0.001 to 20% by weight relative to the total weight of the composition.
- compositions according to the invention may also comprise any additive usually used in the cosmetic or pharmaceutical field, such as sequestrants, antioxidants, preservatives, fillers, electrolytes, humectants, dyes, bases or acids usual, mineral or organic, perfumes, essential oils, cosmetic active ingredients, moisturizers, vitamins, essential fatty acids, sphingolipids, self-tanning compounds, soothing and protective agents for the skin.
- any additive usually used in the cosmetic or pharmaceutical field such as sequestrants, antioxidants, preservatives, fillers, electrolytes, humectants, dyes, bases or acids usual, mineral or organic, perfumes, essential oils, cosmetic active ingredients, moisturizers, vitamins, essential fatty acids, sphingolipids, self-tanning compounds, soothing and protective agents for the skin.
- any additive usually used in the cosmetic or pharmaceutical field such as sequestrants, antioxidants, preservatives, fillers, electrolytes, humectants, dyes, bases or acids usual, mineral or organic, perfume
- additives can be present in the composition in an amount of 0.001 to 20% by weight relative to the total weight of the composition.
- the present invention also relates to a pharmaceutical composition as described above as a medicament.
- the present invention also relates to a cosmetic composition.
- compositions containing the combination according to the invention can have all the dosage forms normally used for topical application, for example in the form of solutions, gels, dispersions of the lotion or serum type, emulsions of liquid or semi-liquid consistency of the milk type, obtained by dispersion of a fatty phase in an aqueous phase (O / W) or vice versa (W / O), or of suspensions or emulsions of soft, semi-solid or solid consistency of cream or gel type, or else microemulsions, microcapsules, microparticles or vesicular dispersions of ionic and / or nonionic type.
- These compositions are prepared according to the usual methods.
- the cosmetic or dermatological compositions of the invention may contain adjuvants customary in the cosmetic or dermatological field, such as emulsifiers, hydrophilic or lipophilic gelling agents, hydrophilic or lipophilic active agents other than titanium oxide and ⁇ -hydroxy acid, preservatives, antioxidants, perfumes, fillers, filters and coloring matters.
- adjuvants customary in the cosmetic or dermatological field, such as emulsifiers, hydrophilic or lipophilic gelling agents, hydrophilic or lipophilic active agents other than titanium oxide and ⁇ -hydroxy acid, preservatives, antioxidants, perfumes, fillers, filters and coloring matters.
- the amounts of these various adjuvants are those conventionally used in the cosmetic and / or dermatological fields, and for example from 0.01% to 20% of the total weight of the composition.
- These adjuvants depending on their nature, can be introduced into the fatty phase, into the aqueous phase and / or into the lipid vesicles.
- the invention also relates to the use of the composition according to the invention as described above in the pharmaceutical and cosmetic field.
- compositions of the invention are particularly suitable for the treatment and prevention of pigmentation disorders.
- the compositions of the invention are suitable for the treatment and prevention of hyperpigmentary disorders such as melasma, chloasma, lentigines, senile lentigo, vitiligo, freckles, post-inflammatory hyperpigmentations due to abrasion. , a burn, a scar, a dermatosis, a contact allergy; nevi, hyperpigmentations with genetic determinism, hyperpigmentations of metabolic or drug origin, melanomas or any other hyperpigmentary lesions in particular those induced by photo induced or chronological aging of the skin and integuments.
- compositions according to the invention are suitable for the treatment of melasma.
