Description

  The present invention relates to an improvement in the field of nail care products. In particular, the present invention relates to a cosmetic composition for improving the structure of the nail.

Mammalian nails, especially human fingernails and toenails, are composed of transparent cells of the epidermis called keratinocytes produced at the nail roots. These cells combine to form a hard and continuous surface behind the distal phalange.
Each nail adheres closely to the underlying support that forms the base of the nail. The visible part of the nail is called the nail body. The hidden part is called the root.

The proliferation of the root keratinocytes ensures nail growth. New cells undergo a change to a solid layer and dry until they form a solid plate. The nail permanently receives a continuous addition of cells at its foundation level, pushing the foundation beyond the tip of the phalange.
Keratin fibrils are present in the keratinocytes, and intercellular cement provides rigidity and flexibility to the nail.

  Unfortunately, nail brittleness and fragility are observed in mechanical, thermal and / or chemical attacks. For example, brittle and friable nails eventually break, crack or crack due to mechanical impact. Similarly, nails are degraded by the presence of aggressive chemicals, particularly those present in household products. Similarly, nail degradation is also a secondary effect of the aging process. Nail degradation is very painful, uncomfortable and ugly, and can cause foreign body infection of the nail.

  A number of approaches have been investigated to improve the resistance of nails to different attacks with mechanical, thermal, chemical or temporal properties by hardening or strengthening them. Various chemical products such as synthetic rubber-based compositions of acrylic polymer films, nitrocellulose-based varnishes combined with inert glass fibers, and other hardeners are described in US Pat. No. 5,508, respectively. No. 027, No. 4,873,077, No. 4,482,538, and No. 5,785,959. While these compositions may have a stiffening or strengthening effect on the nail, they do not allow those skilled in the art to improve the structure of the nail. When these compositions are applied to brittle or soft nails, harder nails are obtained, but the latter is still prone to cracking and cracking.

  Several approaches have also been investigated to improve nail softness and tolerance by giving them nourishment and moisture. Many attempts have been made to protect the nails from dehydration and protect them from various types of attacks. Compositions containing synthetic active agents such as humectants, antimicrobial agents or antifungal agents have been widely proposed.

  US Pat. No. 6,517,863 discloses compositions and methods for improving the durability and hardness of nail bodies. The composition increases the durability of the nail by forming a protective layer of hydroxyapatite or other calcium phosphate mineral on the nail. Such compositions contain synthetic and inorganic bioactive glasses as active substances. These inorganic glass materials are bonded to the nails and include a plurality of synthetic chemical products.

  US Pat. No. 5,645,823 discloses an aqueous solution for restoring and maintaining the balance of the composition of normal, healthy keratinous tissue and their adjacent structures. The latter composition comprises a plurality of synthetic compounds used as antimicrobial agents or active substances.

U.S. Pat. No. 4,919,920 discloses a composition and method for reinforcing and hardening a mammalian keratinous appendage, wherein fluoride ions in an aqueous cosmetic carrier are locally applied. Applied. The use of fluoride ions also increases the hardness and resistance of the nails. However, this method has the disadvantage of increasing the acidity in situ. Similarly, US Pat. No. 5,478,551 discloses the use of fluoride ions to strengthen the nails. A non-aqueous organic composition comprising ammonium hexafluorophosphate is used to provide the nail body with an effective amount of fluoride ions. In the latter two cases, harmful acidic by-products may possibly be formed.
Although the above compositions may prevent nail brittleness, all of them contain synthetic chemicals as the main active substance, but long term and / or secondary effects are still completely known in that regard Absent.

  During the last decade, our social thinking about synthetic products has changed considerably in the area of pharmaceutical, nutrient and cosmetic concerns. The trend is to avoid synthetic products as much as possible and replace them with natural or organic products. The advent of functional foods, dietary supplements and natural cosmetics represents a good example of this trend. People are now strongly aware of the fact that frequent or long-term consumption or use of chemicals may have negative effects and side effects on human health. Since many of these chemicals are relatively recent, the long-term effects are often unknown. Thus, natural or organic products are widely used as active substances for drugs or cosmetics. For example, US Pat. No. 5,667,768 discloses a nail care composition comprising an organic solution or a dispersion of at least one natural active agent. However, they must be used 2-3 times per week for at least 8 weeks to provide results, making the use of such compositions tedious.

  Accordingly, it is an object of the present invention to overcome the above drawbacks and provide a composition for improving the structure of the nail, which contains a natural active substance as the main active ingredient.

Example 1

Example 2

The nail polish compositions of Examples 1 and 2 were tested to determine their effectiveness in improving nail structure. Four female subjects were selected to carry out such a test. Initially, the nail quality of the test subject is evaluated as 1 to 10 as defined below:
-Grades 1 to 3 correspond to very thin and peeled nails; such nails are usually polished using 400 or 600 grit files and are considered very weak nails;
-Grades 4-6 correspond to moderately weak nails that break regularly; such nails are usually polished using a 300 grit file and are considered weak against the average nail;
-Grades 7 and 8 correspond to good quality nails that rarely break; such nails are usually polished using a 200 grit file and are considered good nails; and-Grades 9 and 10 are very thick Such nails are usually polished using a 120 grit file and are considered excellent nails,
Quantified by using.

  The four selected subjects were 20-50 years of age and had different grades of nails. The nails of subjects 1, 2 and 3 were treated with the nail polish composition of Example 1, and the nails of subject 4 were treated with the nail polish composition of Example 2.

Subject 1
Subject 1 was very thin and had brittle nails before being treated with the nail polish composition of Example 1. In particular, the nails were grade 1 and were initially polished by a 600 grid file. At the beginning of the treatment, the subject's nails were cleaned using a nail polish remover and a two-layer nail polish composition was applied to the nails. During the following 4 weeks, a new bilayer composition was applied each week. The nail was polished before applying the new layer and the previously applied layer was removed using a nail remover. During the third week, a noticeable improvement in the nails was noticed. The nails were grade 2 and no further thickness and peeling was observed. After 5 weeks of treatment, the nail was improved from grade 1 to grade 3, and a 400 grit file was needed to polish the nail.

Subject 2
Subject 2 had good quality nails, but the nails of both hands were of different quality, i.e., the right hand nails were of grade 7 and the left hand nails were of grade 6. Subject 2's nails were polished with a 200 grit file. Considering the nail quality, the nail of subject 2 was the same as described for subject 1, except that only one layer of the nail polish composition of Example 1 was applied instead of two layers each week. It was applied to. During the second week, he noticed a substantial improvement in the nails. The nail on the right hand was grade 8 and the nail on the left hand was grade 7. After 5 weeks of treatment, the nails of both hands were longer and homogeneous and a high growth rate was observed. The nails on both hands became Grade 9 nails, and here a 120 grit file was more appropriate for brushing the nails.

Subject 3
Subject 3 had 2 grades of weak and short nails that were very fragile and of uneven length. Prior to applying the nail polish composition of Example 1, the nails were polished with a 400 grit file. Subject 3's nails were processed according to the same procedure as described for subject 1. During the third week, the nails were grade 3; they were longer and of similar length. After 5 weeks, the nail quality went up to 4 grades for some nails and 5 grades for others, and all of them needed to be polished with a coarser grit, for example a 300 grit file.

Subject 4
Subject 4 had an average thickness of grade 5 nails prior to treatment with the nail polish composition of Example 2. Prior to using the composition, the nails were first polished with a 300 grit file. The same procedure as described for subject 2 was applied to the nail of subject 4 except that the nail nail polish composition of example 2 was applied instead of the nail nail polish composition of example 1. During the second week, the nail quality rose to grade 6, and after 5 weeks a marked improvement in nail quality was observed. In particular, the nails were longer and their growth rate was greater. During the 5 week treatment, the nail quality rose from grade 5 to grade 8 and therefore 200 grit files were finally more suitable to polish them.

  In view of the above results for subjects 1 to 4, it is clear that the nail polish compositions of Examples 1 and 2 improve the nail structure. For all the subjects described above, the treated nails appeared stronger and thicker, all of which demonstrated a high growth rate. It has been demonstrated that when nails have a quality of grade 5 or higher, only one layer of composition is required to improve the structure of the nails.

  Thus, by using the nail polish composition described above, improvement of the nail structure is rapidly observed. For grades 1 to 3, nail was noticed after 3 weeks of treatment, and for grades 4 and above, improvement was noticed after only 2 weeks of treatment.

  From experiments conducted in subjects described above that treatment with the composition of the present invention can be advantageously continued for more than 5 weeks and by doing so the user remains in improved nail quality Should be understood. Similarly, it should be noted that improvements in nail quality can be obtained more rapidly by using the compositions of the present invention once or twice per week. For example, subject 1's treatment was extended to 7 weeks. At 6 weeks, two new layers were applied, and after a few days additional layers were applied without removing the two previously applied layers. At 7 weeks, nail quality reached 4 grades. The composition of the present invention may be applied to the nail by a professional nail specialist or customer.
