Description

~ ~ 7~2~

La presente invention a pour objet une nouvelle composition hu~ectante utilisable dans des compositions cosmé-tiques ou pharmaceutiques.
Il es-t de pratique courante d'utiliser en cosmétique des humectants c'est-~-dire des substances hygroscopiques per-mettant d'absorber l'humidité de l'air ambiant et de maintenir la teneur en eau des compositions de sorte que celles-ci n'ont pas tendance à sécher. Par ailleurs les propriétés hygroscopi-ques du film d'humectant lorsqu'il est appliqué sur la peau constitue un facteur important permettant d'influencer favora-blement la souplesse et le toucher de la peau.
Parmi les nombreuses substances humectantes les plus r couramment utilisées on peut citer les sels de sodium tels que le lactate de sodium ou le pyrrolidone carboxylate de sodium, les polyols tels que la glycérine, le sorbitol et le propylène glycol ainsi que d'autres substances telles que l'urée. r Il a également été proposé d'utiliser des.mélanges de ces substances bien que l'on n'ait pu constater dans ce cas un effet particulièrement sensible de synergie.
Parmi ces mélanges il a été tout particulièrement dé-crit dans le brevet britannique n1.471.679 l'association d'a-cide pyrrolidone carboxylique ou d'un de ses sels hygroscopi-ques, d'un sel d'acide ~-hydroxy carboxylique en C2-C5 et no-tamment le sel de sodium de l'acide glycolique ou lactique et d'une substance polypeptidique de collagene modifie.
Selon ce brevet on doit entendre par l'expression ~<substance polypeptidique de collagène modifié une substance polypeptidique ayant des groupes amino quaternisés avec un ion halogénure et ayant des groupes carboxy terminaux estérifiés par un amino-alcool en C3-C12 ou une substance polypeptidique r ayant des groupes amino terminaux ayant réagi avec un acide gras saturé ou insaturé et ayant des groupes carboxy terminaux ayant ~7~5 réagi avec un polyol, la substance polypeptidique dans chaque cas etant derivee de collagène et possedant un poids molecu-laire moyen correspondant à un di, tri ou tetrapeptides.
D'après ce brevet les proportions des différents in-gredients peuvent varier dans un rapport en poids de 0,75-1,25 pour l'acide pyrrolidone carboxylique ou son sel hygroscopique, de 0,75 a 1,25 pour le sel d'acide ~-hydroxy carboxylique en C2-C5 et de 3,75 à 6,25 pour le derive polypeptidique de colla-gène modifie.

-10 La presente invention se rapporte egalement à une association particulière d'agents humectants permettant de conférer une excellente conservation des compositions et de conférer par ailleurs des propriétés adoucissantes et assou-plissantes de la peau.
La présente invention a pour objet une composition humectante contenant en solution aqueuse:
- du lactate de sodium en une proportion de 3 à 8%, - de la glycerine en une proportion de 12 à 24%, - de l'uree en une proportion de 30 à ~2%, et ~ de 0,05 à 0,2% en poids de collagène natif.
Les differents essais effectues ont permis de montrer que seule cette association dans les proportions mentionnees ci-dessus etait susceptible de conferer les proprietes recher- ;
chees.
En particulier il s'est avere que la presence du collagène natif était indispensable en vue de l'obtention d'un bon pouvoir humectant.
De préference la composition humectante selon l'in-vention contient en solution aqueuse:

3~ - de 4 à 7% en poids de lactate de sodium, - de 15,5 à 21% en poids de glycerine, - de 33,5 à 39% en poids d'uree,
~: ~
~ ~ 7 ~ 2 ~

The subject of the present invention is a new hu ~ ectante composition usable in cosmetic compositions ticks or pharmaceuticals.
It is common practice to use in cosmetics humectants that is ~ ~ say hygroscopic substances per-putting to absorb moisture from the ambient air and maintain the water content of the compositions so that they do not not tend to dry. Furthermore, the hygroscopic properties of the humectant film when applied to the skin is an important factor to influence favora-the suppleness and feel of the skin.
Among the most common humectants commonly used include sodium salts such as sodium lactate or sodium pyrrolidone carboxylate, polyols such as glycerin, sorbitol and propylene glycol as well as other substances such as urea. r It has also been proposed to use mixtures of these substances although it was not possible to observe in this case a particularly sensitive synergistic effect.
Among these mixtures it has been particularly distinguished written in British Patent No. 1,471,679 the association of-cide pyrrolidone carboxylic or one of its hygroscopic salts ques, a salt of ~ -hydroxy carboxylic acid C2-C5 and no-especially the sodium salt of glycolic or lactic acid and of a modified collagen polypeptide substance.
According to this patent, the expression "
~ <modified collagen polypeptide substance a substance polypeptide having quaternized amino groups with an ion halide and having esterified terminal carboxy groups by a C3-C12 amino alcohol or a polypeptide substance r having terminal amino groups which have reacted with a fatty acid saturated or unsaturated and having terminal carboxy groups having ~ 7 ~ 5 reacted with a polyol, the polypeptide substance in each case being derived from collagen and having a molecular weight medium area corresponding to a di, tri or tetrapeptides.
According to this patent the proportions of the different in-gredients can vary in a weight ratio of 0.75-1.25 for pyrrolidone carboxylic acid or its hygroscopic salt, from 0.75 to 1.25 for the ~ -hydroxy carboxylic acid salt in C2-C5 and from 3.75 to 6.25 for the polypeptide derivative of colla-gene changes.

The present invention also relates to a special combination of humectants allowing confer excellent preservation of the compositions and also confer softening and softening properties skin wrinkles.
The subject of the present invention is a composition humectant containing in aqueous solution:
- sodium lactate in a proportion of 3 to 8%, - glycerin in a proportion of 12 to 24%, - urea in a proportion of 30 to ~ 2%, and ~ from 0.05 to 0.2% by weight of native collagen.
The various tests carried out have shown that only this association in the proportions mentioned above was likely to confer the desired properties;
chees.
In particular, it turned out that the presence of native collagen was essential in order to obtain a good moisturizing power.
Preferably the humectant composition according to the vention contains in aqueous solution:

3 ~ - from 4 to 7% by weight of sodium lactate, - from 15.5 to 21% by weight of glycerine, - from 33.5 to 39% by weight of urea,

2 ~ ~
et - du collagene nati en une proportion inférieure a 0,2% en poids.
Par collayène natif, on entend un collagène presentant les caractéristiques suivantes:
Il es-t constitue d'une triple helice comprenant trois chaines helicoidales ~, ~ et y dont les masses moléculaires respectives sont 100.000, 200.000 et 300.000.
La chaine ~ est constituee de 2 sous-unités ~1 et ~2~
chacune de masse moleculaire 100.000, et se difEerenciant legè-rement entre elles par la nature des acides amines qui les constituent.
La chaine ~ est constituee de deux sous-unites ~
laquelle est constituee de 2 sous-unites ~1' et ~12' laquelle est constituee d'une sous-unites ~1 et d'une sous-unite ~2.
Chacune des sous-unités ~11 et ~12 a une masse molé-culaire de 200.000.
D'autre part, ~ l'extrémite de chaque helice, selon le mode d'extraction du collagène, se trouve ou non une chaine lineaire polypeptidique, dite telopeptide, de longueur 50 A en-viron.
Le collagène utilise dans les compositions selon l'invention peut presenter des telopep-tides ou non.
Ce collagène na-tif se differencie totalement de la substance polypeptidique de collagène modifie utilise dans le brevet britannique n1.471.679 par le fait que selon l'invention il s'agit de collagène natif extrait à froid de la peau de jeunes animaux et plus particulierement de la peau de jeunes veaux.
Du fait des conditions particulieres de son extraction ce collagène natif est donc de structure non modifiee et est non ~ -degradee.

La composition humectante selon l'invention peut être 1 ~7~2~5 employée dans toutes les compositions necessitant generalement la presence d'un agent humectant soit pour une bonne conserva-tion des compositions soit pour ameliorer l'apparence ou l'as-pect de la peau.
Parmi les compositions dans lesquelles la composition humectante selon l'invention peut être employee on peut en par-ticulier citer sans que cette enumeration soit limitative les lotions, les cremes de soins pour le visage, les laits corporels, les laits ou crèmes demaquillantes, les laits ou crèmes anti-solaires, les fonds de teint, les crèmes teintees, les crèmes anti-rides ou pour le contour des yeux.
De façon generale on utilise en vue d'obtenir de bons resultats une proportion de 5 ~ 60% en poids de la composition humectante selon l'invention.
De meme la composition humectante selon l'invention peut être utilisee dans des compositions pharmaceutiques ou plus particulièrement dermopharmaceutiques dans les mêmes proportions.
On va maintenant donner à titre d'illustration plu-sieurs exemples de compositions humectantes selon l'invention ainsi que plusieurs exemples de compositions cosmetiques ou pharmaceutiques les contenant.

and - collagen nati in a proportion lower than 0.2% by weight.
By native collayene is meant a collagen having the following features:
It is made up of a triple helix comprising three helical chains ~, ~ and y whose molecular masses are 100,000, 200,000 and 300,000, respectively.
The chain ~ consists of 2 subunits ~ 1 and ~ 2 ~
each with a molecular mass of 100,000, and differing slightly rement between them by the nature of the amino acids which constitute.
The chain ~ consists of two subunits ~
which consists of 2 subunits ~ 1 'and ~ 12' which consists of a subunit ~ 1 and a subunit ~ 2.
Each of the sub-units ~ 11 and ~ 12 has a molecular weight cular of 200,000.
On the other hand, ~ the end of each propeller, according to the collagen extraction mode, whether or not there is a chain linear polypeptide, called telopeptide, of length 50 A in wrong.
The collagen used in the compositions according to the invention may or may not have telopep-tides.
This naive collagen is totally different from modified collagen polypeptide substance used in the British Patent No. 1,471,679 by the fact that according to the invention it is native collagen extracted cold from the skin of young animals and more particularly young skin calves.
Due to the special conditions of its extraction this native collagen is therefore of unmodified structure and is not ~ -degraded.

The humectant composition according to the invention can be 1 ~ 7 ~ 2 ~ 5 used in all compositions generally requiring the presence of a humectant is either for good preservation tion of the compositions either to improve the appearance or the pect of the skin.
Among the compositions in which the composition humectant according to the invention can be used it can in part particular to quote without this list being limiting the lotions, facial creams, body milks, cleansing milks or creams, anti-aging milks or creams sunscreens, foundations, tinted creams, creams anti-wrinkle or for the eye area.
Generally we use to obtain good results a proportion of 5 ~ 60% by weight of the composition humectant according to the invention.
Likewise the humectant composition according to the invention can be used in pharmaceutical compositions or more particularly dermopharmaceuticals in the same proportions.
We will now give by way of illustration more examples of humectant compositions according to the invention as well as several examples of cosmetic compositions or pharmaceuticals containing them.
