Abstract
The invention relates to wrinkling modifiers and anti-aging cosmetic compositions which each comprise a guanidine derivative represented by the following general formula (1):
is a heterocyclic group selected from azetidine, pyrrolidine, piperidine, piperazine or morpholine, and R1 and R2 are the same or different from each other and independently a hydrogen atom, or an alkyl, hydroxyl, hydroxyalkyl, carboxyl, carboxyalkyl or amidino group, or a salt thereof. The cosmetic compositions are excellent in the effects of suppressing wrinkling and of removing wrinkles and give users a pleasant feeling upon use.
Description
- The present invention relates to wrinkling modifiers and anti-aging cosmetic compositions, and more particularly to anti-aging cosmetic compositions which are excellent in the effects of suppressing wrinkling and of removing or smoothing wrinkles.
- It is a significant concern of, particularly, women to maintain the healthy and beautiful skin. However, the condition of the skin is always affected by factors such as humidity, ultraviolet rays, cosmetic compositions, aging, diseases, stress and eating habits. As the result thereof, various skin troubles such as the decrement of various functions of the skin and the aging of the skin occur. Of these, wrinkles occur due to dermal aging by aging, light aging by exposure to sunbeam, or the like. More specifically, cells f or producing fibers of the dermis are made small and lessened by exposure to sunbeam or with the increase in age. In particular, collagen fibers are lost to a great extent, and so the skin is aged by degeneration of the dermis, reduction of subcutaneous adipose tissue and the like, which forms the cause of wrinkling, relaxation, and loss of resilience.
- Various compositions and methods have heretofore been proposed for preventing or treating the aging effects such as wrinkling [Japanese Patent Application Laid-Open Nos. 185005/1987, 502546/1987, 72157/1990, 288822/1990 and 41419/1995, Japanese Patent Application Laid-Open (KOHYO) No. 510542/1994 (through PCT route), etc.]. However, all of these proposals have not been fully satisfactory in the effect of modifying wrinkling (or preventing wrinkling and removing wrinkles). There has thus been a demand for development of cosmetic skin care compositions excellent in the effect of modifying wrinkling.
- It is an object of the present invention to provide wrinkling modifiers and anti-aging cosmetic compositions which can solve the above-described problems, are excellent in the effects of suppressing wrinkling without impairing normal dermatophysiology and removing wrinkles, and give users a pleasant feeling upon use.
- In view of the foregoing circumstances, the present inventors have carried out an extensive investigation with a view toward achieving the above object. As a result, it has been found that guanidine derivatives having a specific structure or acid-addition salts thereof are excellent in the effect of modifying wrinkling and give users a pleasant feeling upon use, thus leading to completion of the present invention.

-
- (1) Hairless mice (HR/ICR, aged 6 weeks at the beginning of the experiment) were,exposed to UVB 3 times a week by using 6 Toshiba healthy lamps, 20SE. The amount of energy was measured by means of a UV-Radiometer, UVR-305/365D manufactured by TOKYO OPTICAL K.K. The dose upon one exposure was determined to be 1 MED or less, i.e., 65 mJ in an amount of energy of 0.28 mW/cm2. The exposure was effected for 20 weeks. After confirming that the hairless mice had got wrinkles at their backs, they were divided into groups each consisting of 8 mice. Aqueous ethanol (water/ethanol=50/50 vol. %) solutions separately containing Compounds (1) to (16) at a concentration of 4% were applied 5 times a week to their corresponding groups of mice over 6 weeks in a dose of 100 μl. As a control, aqueous ethanol (water/ethanol=50/50 vol. %) was applied in a dose of 100 μl like the samples. After completion of the application, the degree of wrinkles was visually observed to evaluate the samples in accordance with the following standard (wrinkle index). The results are shown in Table 1.
- (Wrinkle index)
- 1: Wrinkles were completely removed or smoothed;
- 2: Wrinkles were scarcely observed;
- 3: Wrinkles were somewhat observed;
- 4: Wrinkles were observed to a great extent.
- (2) In order to further analyze the particulars of wrinkles, skin replicas of the size of 14 mm in diameter were gathered from a portion of the back in each of the mice using a Hydrophilic Exaflex hydrophilic vinylsilicone impression material. Each of these replicas was held horizontally and illuminated at an angle of 30 degrees from the horizontal direction, thereby finding a proportion of shadows of the wrinkles as an area percent by means of an image analyzer. The results are shown in Table 1.

- Compounds (17) to (21) in which the definitions of the respective symbols in the general formula (2) are as shown in Table 2 were used as the synthetic sphingosine derivatives to evaluate them as to the wrinkling-modifying effect in accordance with the same process as in Example 1. The experiment was conducted at concentrations of 5% for the guanidine derivatives and 0.5% for the synthetic sphingosine derivatives.
