- the compounds with a lipoamino acid structure are N-acylated amino acid derivatives corresponding to the following general formula:
- R generally represents the characterizing chain of a fatty acid, saturated or unsaturated, linear or branched, having from 3 to 30 carbon atoms; and R 'represents a characterizing chain of an amino acid.
- characterizing chain used in the context of the present application designates the non-functional main chain of the fatty acid or of the amino acid considered.
- the characterizing chain will be the chain represented by R, while for an amino acid represented by the general formula HoN-CHR'-COOH, the characterizing chain will be the chain represented by R '.
- N-acylated amino acid derivatives are most often in the form of mixtures obtained by acylation of a mixture of pure amino acids or derived from the complete hydrolysis of proteins.
- proteins may be of animal origin, such as, for example, collagen, elastinc, keratin or casein, or alternatively of vegetable origin, such as in particular cereals, or oilseeds.
- lipoamino acid compounds are, because of their amphiphilic structure, particularly advantageous biological vectors as regulators of skin physiology and prove to be suitable for multiple applications, in particular in cosmetics.
- the properties of these compounds generally follow from the nature of the fatty chains and the amino acids constituting them.
- the characterizing chains of palmitic acid (Cl 6) are generally known in the cosmetic field for their softening and emollient properties.

- the characterizing chains of lauric acid (Cl 2) are, for their part, known in cosmetics for their surfactant properties which, a priori, are not compatible with soothing properties.
- sodium lauroylglutamate and sodium cocoylglutamate have been described as gentle agents for cleaning the skin and mucous membranes. We know that these products are non-irritating to the skin. However, no document known to the Applicant suggests that such products would have a soothing activity capable of being curative.
- soothing activity is intended to designate within the framework of the present application any property of a product which, applied topically, makes it possible to help the skin curatively curb against stress caused by an external aggression of a chemical nature (use of cosmetic products containing various specific raw materials, delipidating effect due to the use of surfactant solutions, ctc ...), dc solar nature (irritation by exposure to ultraviolet rays, sunburn, etc.), or even mechanical nature (shaving irritation, hair removal, etc.).
- soothing activity will be understood to mean any activity exercising with respect to the enzymes intervening during an inflammation and in particular with respect to the elastase. It has been discovered quite unexpectedly, and this constitutes the basis of the present invention, that compounds with a lipoamino acid structure comprising a fatty chain having 12 carbon atoms, preferably constituted by a lauroyl radical, exhibit an extremely soothing efficacy. interesting, and superior to that of compounds with a lipoamino acid structure whose fatty chain is a palmitic chain.

- This enzyme is particularly capable of degrading many macromolecules such as fibrous elastin, certain types of collagen, proteoglycans, glycoproteins.
- human leukocyte elastase is one of the links in the chain of reactions accompanying an inflammation phenomenon.
- the blocking of this enzyme by an anti-elastase effect therefore makes it possible to prevent the degradation of the aforementioned molecules and therefore to inhibit the process of inflammation.
- the anti-clastatic properties of a given product can be demonstrated by an in vitro test, carried out with a spectrophotometer, using a support substance capable of degrading by coloring, in contact with human leukocyte elastase.
- Such a substance can be for example N-methoxysuccinyl-alanine-prolinc-valinc-para-nitroanilidc, normally colorless substance which liberates, by hydrolysis by human leukocyte elastase, a colored product, para-nitroalinine, whose kinetics d appearance can be followed by spectrophotometry at 410 nm.
- the reaction is carried out in a spectrophotometer thermostatically controlled at 25 ° C., having a sample changer. All the kinetics are carried out at least three times, the mean and the standard deviation then being calculated for the three values obtained.
- the amino acids as well as the mixed potassium and magnesium aspartate tested alone do not exhibit anti-elastatic efficacy, even at high concentration.
- the lauric chain has limited efficacy at high concentration and no efficacy at low concentration.

- Palmitoyl collagcn amino acid (according to INCI designation). The results obtained show the significant superiority of the anti-elastatic activity of the compounds with lipoamino acid structure of formula (I) according to the invention whose fatty chain is derived from lauric acid, with respect to analogous compounds whose fatty chain is derived from palmitic acid.
- the lauroylaspartatc, lauroylglycinatc and lauroylalaninatc have a relatively weak anti-elastatic activity, but still equivalent, or even superior to that of lipoamino acids whose fatty chain is constituted by a palmitic chain.
- the LML and LCO products also have an anti-elastic efficacy but significantly lower than that of lauroyl glutamate and that of the complex product of Example 3.
- Example 5 Demonstration by an in-vivo test of the soothing effect of compounds with a lipoamino acid structure of formula (IV Principle of the test:
- SEPIGEL + LANOL 99 was evaluated on 5 people, after sun exposure.
- the soothing effect of the product of Example 3 was compared with that of a product known for its soothing properties, glycerrhetinic acid. This product was formulated at
- the products studied (3% product of Example 3; 1% glycerrhetinic acid) are applied immediately after irradiation and then after 12 hours.
- the soothing effect of the products studied is determined by the evaluation of the intensity of erythematous reactions obtained 24 hours after irradiation in the skin areas (evaluation of erythema by colorimetric measurement).
- EXAMPLE 6 Demonstration by an In Vivo Test of the Soothing Effect of Compounds with a Lipoamino Acid Structure of Formula (IV, cn Particularly on Persons with Sensitive and Reactive Skin. Principle of the Test
- Example 3 The soothing effect of the product of Example 3 formulated at 3% was evaluated on people with sensitive and reactive skin.
- the characteristic sensations of sensitive skin can be caused, for example by a topical application of an alpha-hydroxy acid (AHA) such as lactic acid and the responses obtained seem well correlated to the state of sensitive skin.
- AHA alpha-hydroxy acid
- panelists with "hypersensitive" skin are selected. This selection is made as follows:. a 10% solution of lactic acid in physiological saline is applied to the nasolabial folds,
- the tingling sensations are then evaluated immediately after application at the level of the two grooves, on the basis of a visual analog scale at 6 points.
- the following test is carried out:. a 10% lactic acid solution is applied to the two nasolabial folds (right and left) of each volunteer.
- Example 3 the product of Example 3 formulated at 3% is applied as is, only once, as soon as the tingling induced by lactic acid appears.
- the intensity of the tingling is evaluated during the 5 minutes following the application in the area having received the lactic acid (control) and in the area treated with the product to be studied.
- the average intensity of tingling was determined, at each time of the test, by calculating the average of the individual data obtained on all of the volunteers.
- PRODUCTS T "0" (before Immediate 10 sec after 30 sec after 1 min after 2.5 min 5 min after
- control area causes a persistent tingling sensation up to 5 minutes.
- product of Example 3 allows a statistically significant decrease in the intensity of tingling, immediately after application, then during the following 5 minutes, compared to the control area.
- the intensity of the tingling decreased by approximately 46% immediately after the application of the product of Example 3 and decreased the tingling by approximately 90% one minute later compared to the control zone.
- Example 3 after a single skin application, has a very clear, immediate and persistent anti-tingling effect on the sensations induced in the nasolabial fold by a 10% lactic acid solution in people with "hypersensitive" skin.
- the products according to the invention therefore make it possible to very clearly and significantly reduce these reactions.
