Definitions
- the invention relates to a composition for cosmetic use for the protection of the skin against the harmful effects of ultraviolet solar radiation.
- UV radiation can be harmful to humans.
- a large part of the solar energy is emitted in the form of UV radiation, which penetrates deeply into the epidermis.
- the skin to defend itself from this radiation, synthesizes melanin which is a pigment able to absorb the UV and to limit their deep penetration into the dermis.
- melanin synthesized varies from one individual to another and the filtration is not sufficient to safely protect against solar aggressions.
- UVB wavelengths between 280 and 320 nm cause erythema and burns on sensitive skin or frequently exposed to the sun.
- UVA wavelengths between 320 and 400 nm if they allow tanning, are also known to accelerate the aging of the skin and are involved in the development of many skin cancers.
- compositions mostly topical, intended to protect the skin from solar aggressions when it is exposed.
- compositions frequently include carotenoids known to be used by plants to protect themselves from sun attack.
- Carotenoids are rather orange and yellow pigments found in many living organisms. They belong to the chemical family of isoprenoids and are fat-soluble. They are synthesized by algae, green plants and many fungi and bacteria (including cyanobacteria). Animals are not able to produce them, but they find them in their food.
- Carotenoids are known for their photoprotective activity, linked on the one hand to their absorption of light rays (screen role) and on the other hand to their antioxidant properties, which allow them to effectively neutralize the peroxyl radicals and the molecules of singlet oxygen (Sies and Stahl, 1995, 2004). They can be used externally, but also internally, insofar as some of the carotenoids ingested by the animals are found in their integument. Supplementation studies with ⁇ -carotene and lycopene, alone or in combination with other carotenoids, show systemic photoprotection as measured by a decrease in UV-induced erythema.
- norbixin The antioxidant activity of norbixin was also studied on plasmid DNA, inducing free radical breaks by hydrogen peroxide H 2 O 2 in the presence of Sn 2+ or Fe 2+ - Fenton reaction: low concentrations of norbixin (10 ⁇ M) protect the DNA in the presence of 10 ⁇ M H 2 O 2 (Kovary et al., 2001).
- norbixin increases by a factor of 10 the survival of bacteria (E. coli) subjected to UV radiation, hydrogen peroxide H2O2 or superoxide anions O 2 ' .
- the induction of the SOS system by the UVC is reduced by 2.3 fold in the presence of norbixin (Junior et al., 2005).
- norbixin has antimutagenic activity, reducing the mutagenic effect of H 2 O 2 on Salmonella typhimurium by 87% (Kovary et al., 2001).
- a photostable cosmetic filter composition for the protection of the human epidermis against UV radiation, comprising a small amount (0.0025-0.009% by weight) of bixin in an oily extract (Grollier et al., 1991 ).
- carotenoids can also be ingested to play their role antioxidant especially dermal and epidermal cells.
- the ingested compounds are in fact found in the plasma and then in various tissues, including the skin (Richelle et al., 2006).
- Human skin contains on average 0.2 to 0.6 ng / g of total carotenoids, with wide variations between individuals and between body areas (Stahl and Sies, 2007).
- Ingesting food supplemented with carotenoids causes an increase in the carotenoid content of the dermis (Stahl et al., 1998) and, to be effective, these must be used for a prolonged period of time, for a period of more than 10 weeks. (Stahl et al., 2000).
- Carotenoids are generally not or only slightly toxic (Agner et al., 2004), even at chronic doses of 3 g / kg in animals (Trumbo, 2005). Presentation of the invention
- Norbixin is a derivative derived from the alkaline hydrolysis of bixin and is water soluble.
- the inventors have discovered that the culture of human epidermis explants for one week in the presence of bixin, norbixin or urucum extract (containing these two molecules) results in a high protection at a UVB irradiation equivalent to about 2 DEM. protection results in a very significant reduction in the number of sunburn cells (SBCs) observed 24 hours after irradiation ( Figure 1).
- SBCs sunburn cells
- norbixin is the major compound found in plasma after ingestion of bixin.
- norbixin plasma concentrations greater than 25 ng.mL "1 are observed for more than 6 hours, while those of bixin only reach 10 ng.mL "1 for less than 4 hours (Levy et al., 1997).
- the first molecule is ingested at a daily dose of between 5 mg and 100 mg, preferably at a daily dose of 35 mg.
- the daily dose may be between 30 and 40 mg for a person of about 70 kg.

- the lower percentage by weight of norbixin or bixin is determined according to a minimum concentration of norbixin or bixin.
- the minimum concentration of norbixin or bixin is a concentration of norbixin or bixin which below norbixin or bixin according to the invention has no biological effect or photoprotective effect.
- Norbixin or bixin can be obtained by extraction from plants containing norbixin or bixin.

- BRIEF DESCRIPTION OF THE DRAWING FIG. 1 Effects of a bixin-enriched Urucum extract, bixin and norbixin on the number of "sunburn" cells following irradiation of the skin with UVB.
- a first extraction is carried out by stirring for 16 hours. Centrifugal separation is carried out and 400 liters of a first liquid extract A is obtained. The residues are re-extracted with 400 liters of ethanol absolute. The two extracts (800 liters) are mixed and this volume is reduced to 80 liters; 10 kg of cassava starch are added and the whole is spray-dried: 30 kg of a dry extract are thus obtained.
- the preparation of the enriched norbixin extract is made by saponification of the bixin-rich extract by stirring in an aqueous NaOH solution (bixin: NaOH 1: 3 mol / mol) for several hours at 37O. Samples of the saponification reaction can be analyzed by HPLC up to 100% bixin / norbixin conversion. The drying is done by evaporation of the water at 50 ° C. and the Norbixin thus crystallized can remain at -20 ° C. (Kovary ef a /., 2001)
- the urucum extract was dissolved in DMSO.
- the three products were added in the first day culture medium (OJ), so as to reach the desired final concentrations.
- the final amount of DMSO in the medium always remained below 1%.
- the explants of the control lot T did not receive any treatment.
- Sunburn cells were counted throughout each epidermis. The length of each epidermis was measured using the Leica IM1000 software measurement module and the number of SBC per cm of epidermis was then calculated. Number of SBCs per cm.
- the product P1, the product P2 and the product P3 respectively resulted in a significant decrease of 63.9%, 74.4% and 84.4% of the number of SBCs in the epidermis compared to the untreated and irradiated control epidermis.
