The invention relates to a parakeratosis inhibitor that inhibits parakeratosis caused by sebum, a pore-shrinking agent that maintains normal skin conditions around the pore and suppresses a conical structure of the pore from becoming conspicuous by inhibiting parakeratosis caused by stimulatory components in the sebum around the pore, a skin roughness preventing/ameliorating agent that prevents/ameliorates the skin roughness caused by unsaturated fatty acids, and skin preparation for external use that exhibits capabilities of parakeratosis inhibition, pore shrinkage, skin roughness prevention/amelioration, etc.
Recently, many people, young ladies among others, have worried about conspicuous pores and have demanded a skin preparation for external use for making the pore inconspicuous. However, the mechanism for making the pore conspicuous has not been elucidated yet, and use of an astringent lotion and excision of parakeratosis have been usual treatments of parakeratosis. Or the skin problem has been often covered apparently by means of foundation cream. The astringent lotion is used to tighten the skin, and the action thereof is to temporarily reduce the temperature of the skin surface with alcohol, or to coagulate proteins with organic acids and the like. Accordingly, the skin suffers a great burden since the skin is temporarily tightened without fundamentally solving the problem of conspicuous pores, and the effect of the astringent lotion has been insufficient.
On the other hand, it has been reported that the derivatives of glycolic acid and ascorbic acid have the effect of pore shrinking (see, for example non-patent reference #1). The mechanism of action and the extent of effect thereof are still unknown.
Excision of keratin plug is to physically remove the keratin plug. Some known methods of excision include parakeratosis remover containing a high molecular weight compound having salt-generating groups (see, for example, patent reference #1), cosmetics containing water-insoluble cyclodextrin polymers (see, for example, patent reference #2), keratin plug remover cosmetics containing not less than 50 weight % of oil having a coefficient of viscosity of 5 to 80 mPa·s/25 degrees centigrade (see, for example, patent reference #3). Physical removal of the keratin plug may damage the skin by a physical force, and side effects on the skin have been a problem. The effect of this method is not always satisfactory since the effect thereof is temporary and keratin plug is readily regenerated, and removal of keratin plug may only expand the pore.
The inventors of the present invention have made intensive studies on the mechanism of generating the conspicuous pores in order to develop a skin preparation for external use that exhibits capabilities of ameliorating the conspicuous pores, and found and reported at the 102nd annual meeting of Japan Society of Dermatology (see non-patent reference #2) that:
(1) the conically recessed portion around the pore is recognized as pore, and the pores become conspicuous if this portion is wider;
(2) the skin surface stratum corneum of the conical portion is in a state of parakeratosis (there remains nucleus which should have disappeared);
(3) those person having conspicuous pore excretes a lot of sebum, in particular unsaturated fatty acids;
(4) the unsaturated fatty acids cause the parakeratosis; and
(5) the conspicuous pore is likely to be caused by the unsaturated fatty acids contained in the sebum.
The inventors of the present invention have elucidated that the mechanism of developing conspicuous pore may be partly due to parakeratosis caused by the sebum. The inventors have also elucidated that the amelioration of parakeratosis may lead to the amelioration of conspicuous pores.
The present invention has been made in view of above circumstances and has an object of providing a new parakeratosis inhibitor agent that exhibits the capabilities of parakeratosis inhibition, pore-shrinking, skin roughness prevention/amelioration, etc., a pore shrinking agent, a skin roughness prevention/amelioration agent, and a further object of providing a skin preparation for external use having these capabilities.

The present invention will be described in greater details with reference to some preferred embodiments herein below. The blending quantity is weight % unless otherwise notified.
A 3 weight % water solution (including 30 weight % ethanol) was prepared as the evaluation specimen of the glycine derivatives in accordance with the invention 1. The pH was regulated to the range between 7.0 to 7.5, by using hydrochloric acid and sodium hydroxide. When the solubility was low, the solution was adjusted accordingly.
100 microliters of 10 weight % oleic acid (solvent: ethanol) was applied to the back of hairless mice (HR-1, Hoshino laboratory animals). Thereafter, 100 microliters of sample solution was applied (glycine derivatives in accordance with said invention 1) at each time. This procedure was repeated for 3 days. The day after the application, the skin condition of the backs was observed by using a CCD camera to evaluate the skin roughness (stratified ablation of the skin surface stratum corneum and red spots). The skin condition was evaluated visually, with scoring the skin condition of control application to 2.0 and the skin condition of no roughness to 0.0, in a 0.25 point step in response to the skin condition. At the same time, the skin surface stratum corneum of the back of hairless mice was peeled off by using a tape for staining the nucleus with haematoxylin to observe the degrees of parakeratosis (parakeratosis level) and evaluate in 0.25 step in the range from 1.0 to 3.0. The higher evaluation points indicates the larger number of parakeratotic corneocytes count, i.e., severer parakeratosis. The result is shown in Table 1 below.
concentration: concentration in aqueous solution including 30 weight % ethanol.
As can be clear from Table 1, it was shown that sarcosine, glycylglycine, glycine benzyl ester hydrochloride, glycine ethyl ester hydrochloride, glycine n-butyl ester hydrochloride, glycine t-butyl ester hydrochloride, glycine n-propyl ester hydrochloride, phenaceturic acid, N-acetyl-L-glutamic acid, N-benzoyl-L-glutamic acid, benzenesulfonyl-L-glutamic acid, N-acetyl-L-aspartic acid, beta-alanine, beta-alanine ethyl ester hydrochloride, isonicopetinic acid have the effect of inhibiting parakeratosis.
An experiment of application of sample twice a day for a month on the cheek of healthy male subjects, was conducted with each group consisting of 5 individuals. 3 weight % solution of the glycine derivatives in accordance with the invention 1 (including 15 weight % of ethanol) was prepared. pH was regulated to the range between 7.0 and 7.5, by using hydrochloric acid and/or sodium hydroxide. Control was 15 weight % ethanol solution. Said 3 weight % solution was applied to one side and said control solution was applied to the other side.
Replicas were prepared prior to and after the application to observe the change of form of pores in the same spot under a three-dimensional laser scanning microscope. The size of pores was evaluated visually 13 steps from 1 to 13 (larger number indicates larger pore size), and the difference between the resulted evaluations before/after the application experiment was then calculated to study the effectiveness of each specimen. The result is shown in Table 2 below.
As can be appreciated from Table 2, pore-shrinking effect was observed in sarcosine, glycylglycine, N-acetyl-L-glutamic acid, beta-alanine, and phenaceturic acid.
Since we obtained a good result from glycylglycine in the embodiment 2, we conducted an application experiment of glycylglycine three times a day (0.1 milliliter each) on the cheek of 21 healthy adult males (age of 20s to 50s, average 40.4 years old) for a period of one month. 1.6% (w/w) glycylglycine solution (pH regulated to 7.0) including 15% (w/w) ethanol, and 15% (w/w) ethanol solution (control) was prepared, for applying the same to each one side cheek.
By obtaining a cheek replica (Silflo) before and after the continuous application, the surface area of conical portion was measured by a three-dimensional analysis system (Okuri et al., Japan Society of Dermatology Annual Meeting Program/Abstract, 2004, 104, pp. 601) by means of wide view confocal microscope HD100D (lasertech).
For the surface area recognized as pore portion within the replica measuring area of 3.34 mm by 3.34 mm, the conical portion surface area (mm2) and the ratio thereof before and after the application is shown in Table 3. From Table 3, The ratio among the panel that the surface area of glycylglycine applied side was decreased more than 10% when compared to the control application side (glycylglycine side was shrunk), the panel that the variation was within 10% and no noticeable change observed (no change), and the panel that the control application side was decreased more than 10% (other side was shrunk) was 13:5:3.
When averaging the surface area ratio before and after the application, the side of control solvent solution was 102%, while the side of glycylglycine was reduced to 89%. By evaluating this surface area ratio with t-analysis, we obtained p=0.019, indicating significant shrinkage of pore area in the glycylglycine applied side (see
In the photographic evaluation, it was shown that the conspicuous pores in the glycylglycine applied side were ameliorated in comparison to the pores in the ethanol applied side.
The samples to be evaluated of the glycine derivatives and the salts thereof as well as the aminosulfuric acid derivatives and the salts thereof in accordance with the invention 2 were prepared mainly 3 weight % solution (including 30 weight % ethanol, excluding Hydantoic acid and ACES which include 20 weight % ethanol). pH was regulated by using hydrochloric acid or sodium hydroxide to be 7.0 to 7.5. When the solubility was low, then the solution was prepared accordingly.
100 microliters of 10 weight % oleic acid (solvent: ethanol) was applied to the back of Hairless mice (HR-1, Hoshino laboratory animals) Thereafter, 100 microliters of sample solution (glycine derivatives in accordance with the invention 2) was applied thereon at each time. This procedure was repeated for 3 days. The day after the application, the skin condition of the backs was observed by using a CCD camera to evaluate the skin roughness (stratified ablation of the skin surface stratum corneum and red spots). The skin condition was evaluated visually, with scoring the skin condition of control application to 2.0 and the skin condition of no roughness to 0.0, in a 0.25 point step in response to the skin condition. At the same time, the skin surface stratum corneum of the back of hairless mice was peeled off by using a tape for staining the nucleus with haematoxylin to observe the degrees of parakeratosis and evaluate in 0.25 step in the range from 1.0 to 3.0. The higher evaluation points indicates the larger number of parakeratotic corneocytes count, i.e., severer parakeratosis. The result is shown in Table 4 below.
concentration: concentration in aqueous solution including 30 weight % ethanol (excluding hydantoic acid and ACES which are concentration of aqueous solution including 20 weight % ethanol).
As can be clear from Table 4, it was shown that hydantoic acid, N-ethylglycine, N-phenylglycine, glycylglycine ethyl ester hydrochloride, glycyl sarcosine, ACES, CAPS, CAPSO have the effect of inhibiting parakeratosis. On the other hand, as can be seen from the result of reference materials, for example, carboxyl group replaced with amide (i.e., glycine-amide hydrochloride and hydantoin) did not exhibit such effect. The modification of amino group did exhibit effect in case of N-ethyl and N-phenyl groups, however the effect disappeared in case of N,N-dimethyl and N-acetyl groups. The effect was not recognized for CHES (2-(N-cyclohexylamino) ethane sulfonic acid), CABS (4-(cyclohexylamino)-1-butane sulfonic acid), MOPS (3-(N-morpholino) propane sulfonic acid), TAPS (N-tris(hydroxymethyl)methyl-3-aminopropane sulfonic acid), all of which are component compounds of the Good buffer solution and are aminosulfuric acid derivatives.
An experiment of application of sample twice a day for a month on the cheek of healthy male subjects, was conducted with each group consisting of 5 individuals. 3 weight % solution of the glycine derivatives and the salts thereof as well as the aminosulfuric acid derivatives and the salts thereof in accordance with the invention 2 (including 15 weight % of ethanol), 2 weight % solution of ACES (including 15 weight % of ethanol), 3 weight % solution of CAPS (including 15 weight % of ethanol), and 3 weight % solution of CAPSO (including 15 weight % of ethanol) were prepared. pH was regulated to the range between 7.0 and 7.5, by using hydrochloric acid and/or sodium hydroxide. 15 weight % ethanol solution was used as control. Said sample solutions was applied to one side, and said control solution was applied to the other side.
Replicas were prepared prior to and after the application to observe the change of form of pores in the same spot under a three-dimensional laser scanning microscope. The size of pores was evaluated visually 13 steps from 1 to 13 (larger number indicates larger pore size), and the difference between the resulted evaluations before/after the application experiment was then calculated to study the effectiveness of each specimen. The result is shown in Table 5 below.
As can be seen from Table 5, N-ethylglycine, N-phenylglycine, hydantoic acid, glycyl sarcosine, ACES, CAPS, CAPSO demonstrated the effect of pore-shrinking.
In the pore-shrinking effect test on human skin as described in the embodiment 5, the application of N-ethylglycine was further studied about the amelioration of parakeratosis by measuring the number of nuclear cell of skin surface stratum corneum, obtained by means of a tape. Replica was used to actually measure the pore size within the area of 3.34 mm by 3.34 mm to evaluate the pore-shrinking effect.
More specifically, the skin surface stratum corneum was sampled by means of carton tape (Nichiban, Co. Ltd.) only after the application of sample, Hoechst 33342 solution dissolved in PBS to 0.1 mg/ml was then added, and after the sample was placed in a dark place for 20 minutes, the number of nuclear cells within the area of 12 mm by 34 mm by using a fluorescent microscope. For the replicas made by using silflo (Flexico, Co. Ltd.) was measured before and after the application to capture three-dimensional surface form within the same area (3.34 mm by 3.34 mm) with a confocal microscope (HD100D, Lasertech) to measure and compare the size of pores (surface area value).

To study the inhibitory effect on the skin roughness by the application of oleic acid by the glycine derivatives and the salts thereof as well as the aminosulfuric acid derivatives and the salts thereof in accordance with the invention 2, the total evaporation of water (TEWL value) before and after the application was measured to compare the difference therebetween with the value of control (control solution) in order to determine the effect. The preparation of samples and the application procedure were in accordance with the embodiment 4. The TEWL value was measured by means of TEWA meter TM210 (Courage+Khazaka Inc.).
100 microliters of 10 weight % oleic acid (solvent: ethanol) was applied to the back of hairless mice (HR-1, four in each group). Thereafter, 100 microliters of sample solutions (glycine derivatives and the salts thereof as well as the aminosulfuric acid derivatives and the salts thereof) in accordance with the invention 2 were applied at each time. This procedure was repeated for 3 days. The day after the application, TEWL value of the back of mice was measured and the values were averaged. The result is shown in Table 6. The larger delta-TEWL value indicates severer aggravation of skin roughness.
As can be seen from Table 6, the application of hydantoic acid, N-phenylglycine, N-ethylglycine, glycylglycine ethyl ester hydrochloride salt, nicotinoylglycine, ACES, CAPS, CAPSO resulted in a significant decrease of delta-TEWL value as compared to the control solution, thus indicating the skin roughness protecting/ameliorating effect.
