Abstract

Cosmetic composition (I) comprises at least one oily extract of cashew nuts and coco-caprylate/caprate. ACTIVITY : Dermatological. MECHANISM OF ACTION : None given.

Description

The present invention relates to a cosmetic composition comprising at least one oily cashew nut extract and cococaprylate / caprate, and its use for the hydration of the skin. The skin consists of three superimposed layers, from the surface to the depth of the body: the epidermis, the dermis and the hypodermis. The superficial layer of the epidermis, ie the stratum corneeum, is composed of cells called corneocytes, which are very flattened, nucleus-free and highly corneic cells because of a strong proportion of keratin. Corneocytes are the extreme result of the differentiation of keratinocytes that migrate continuously from the basal layer to the upper layers. These corneocytes protect the skin by forming, with the intercellular cement, a barrier, on the one hand against the aggressions of the external environment and on the other hand contribute to avoid an excessive loss of the water contained in the skin and necessary to its good physiological state. The stratum corneum is constantly renewed. Thus, in the normal situation, the oldest corneocytes break off in a regular fashion, in small masses called "squames", and are replaced by younger corneocytes from the lower layers. It is known that a good hydration of the skin accelerates this phenomenon of desquamation, allowing the rapid renewal of the skin and thus contributing to the slowing down of skin aging. We know that it is important to maintain good skin hydration in order to compensate for the dehydration experienced by the skin exposed to the atmosphere and to slow skin aging. It is therefore interesting to have effective moisturizing agents to maintain a moisture content of the appropriate skin. The object of the present invention is therefore to obtain a composition which compensates for dehydration by increasing the amount of water present in the superficial layers of the epidermis.

The present invention thus relates to a cosmetic composition comprising at least one oily cashew nut extract and cococaprylate / cape spleen. By "cashew nut" is meant the fruit of the western Anacardium. Western Anacardium, also called cashew, is a tree of the family Anacardiaceae.

By "oily extract" is meant any type of substances and / or molecules obtained by extraction and having a lipophilic character and liquid at room temperature. Preferably, the oily cashew extract is cashew nut oil. The oily cashew extract is a rare oil comprising essential fatty acids, vitamin A, D, E, K, B3, and mineral salts such as calcium, phosphorus and iron. It contains fatty acids selected from palmitic acid C16, palmitoleic acid C16, margaric acid C17, oleic acid C18, linoleic acid C18. The oily cashew extract also contains sterols, cholesterol, brassicasterol, campestero, stigmasterol, clerosterol, beta-sitosterol, Delta 5-24 stigmastadienol, delta 7-avenasterol. Cashew nut oil contains oleic and linoleic unsaturated fatty acids, making it an excellent anti-aging emollient and regenerator. In addition, vitamin E present in cashew nut oil acts as free anti-radicals. However, free radicals are responsible for skin aging since they alter the structure of phospholipids. The composition according to the invention therefore has improved moisturizing properties, protecting the hydro-lipidic film of the skin and thus creating a barrier effect, which prevents the loss of water in the skin and slows skin aging. Cashew is a rare oil, and extracting oil from cashews is a long and delicate operation. Preferably, this extraction is manual. Indeed, the nuts are harvested and dried before being shelled manually. These nuts are then cooked in an oil bath or steamed in a boiling chamber. The product thus obtained is then dried either in the sun or in an improved drying oven. Finally, the product undergoes a dehulling step which is also manual. Preferably, the oily cashew extract is produced by a single cold pressing. The cashew nuts are pressed in a hydraulic press or in a mechanical screw press. The oily cashew extract is generally liquid and can be defined by a density of about 0.91 to 15 ° C.

For example, it can be used in concentrations ranging from 2 to 10% in skin care products and in after-sun products and up to 3% in bath and shower products and in products hair care. Preferably, the oily cashew nut extract is present in the cosmetic composition according to the invention at a concentration of between 1 and 10%, preferably between 2 and 8% and more preferably between 4 and 6% by weight of the composition.

b) Hydration test. The moisturizing potential of the body cream is evaluated. For this, we study the kinetics of hydration by corneometry for 3 hours out of 10 volunteers. - Principle Corneometry allows the measurement of the hydration rate of the skin before and after application of a cosmetic product in the upper layers of the epidermis.

Measurements of the cutaneous hydration rate are made using the Cornéomètre. The principle used is that of the dielectric capacitance. The stratum corneum is characterized by an average dielectric value. The properties of the dielectric vary with the amount of water contained in the stratum corneum.

The sensor is composed of two metal electrodes. A thin insulating layer separates the electrodes on the end of the probe in contact with the skin. The power supply of the electrical circuit induces an electric field across the stratum corneum and an electric current between the two electrodes. The apparatus measures the corresponding capacitance.

The rate of hydration is measured in an arbitrary unit (u.a.). The higher this value, the more the skin is hydrated. It is also possible to measure the hydration by the percentage of variations in the degree of hydration relative to the time To, that is to say the time before the application of a cosmetic product. - Protocol 0.07 ml of the body cream is applied to a site of 35 cm 2 (treated site) in single application, on the outer face of the legs of 10 women volunteers. These volunteers are aged 18 to 70 years and have dry skin in the legs, defined by corneometric values less than 50 ua The hydration gain is measured at the time of application of the body cream (at time TO) , then after 1h, 2h and 3h (respectively at times Ti h, T2h, T3h). The hydration gain of a control site is also measured at time T0, T1h, T2h and T3h.

Results The results of the corneometric measurements are presented in the table below: Table 3: result of the corneometric measurements Measuring time TO Ti h T2h T3h Hydration rate treated site (in ua) 28.44 47.48 53.03 53.24 Hydration rate control site (in ua) 28.70 29.85 29.42 29.40 Hydration rate variation of the treated site (in 66, 98, 86.48 87.21%) Variation rate hydration control site ( in 3.99 2.50 2.44%) Variation rate hydration site treated - 62.98 83.97 84.77 Variation level hydration site control (in%) At the end of 3h following the unique application of the body cream in level of the legs, the rate of hydration of the site increases from 28.44 ua to 53.24 ua, which represents a variation of 87.21%. The body cream therefore has a moisturizing power of the superficial layers of the epidermis, statistically significant at each measurement time.
