Abstract
Description
Technical Field
[0001] The present invention relates to a cosmetic composition, and particularly to a cosmetic composition containing vitamin B group or its derivatives.
Background Art
[0002] In recent years, research on beauty regarding skin, such as whitening, prevention and improvement of wrinkles, improvement of rough skin, etc. has been actively conducted. For example, many cosmetic compositions containing vitamin B group or its derivatives have been developed.
[0003] Among vitamin B group or its derivatives, for example, niacinamide has attracted attention as a cosmetic active ingredient having both whitening effect and anti-wrinkle effect (such as effects of preventing and improving wrinkles). And when applying a cosmetic composition containing such vitamin B group or its derivatives to the skin, it is desired to enhance the penetration of vitamin B group or its derivatives into the skin to enhance its cosmetic effect.
[0004] For example, in Patent Document 1, as a cosmetic composition that enhances the permeability of an active ingredient to the skin and extends the residence time of the active ingredient in the skin, a cosmetic composition suitable for topical application, which contains i) glycerin, ii) a lipid bilayer structuring agent having a glycerol head group, iii) a penetration enhancer, and iv) a skin care active ingredient, is disclosed.
[0005] On the other hand, as also mentioned in Patent Document 1, various skin penetration enhancers are known, but their mechanism of action, particularly the mechanism of action in the stratum corneum, is still under research, and it is difficult to rationally select a penetration enhancer for a given permeating substance.

[0041] According to the present invention's cosmetic method, the penetration of B vitamins or their derivatives, which are effective cosmetic ingredients, into the skin can be promoted. [Examples]
[0042] The present invention will be explained in more detail below with reference to examples, but the present invention is not limited to these examples. Unless otherwise specified, the numerical values in the tables below represent the amount of each component, and the unit is mass%.
[0043] Examples 1-8 and Comparative Example 1 Based on the formulations in Tables 1 and 2, compositions for Examples 1-8 and Comparative Example 1 were prepared, and the transdermal penetration of the vitamin B group or its derivatives contained in each composition was evaluated.
[0044] In Table 1, the structural formula of (ammonium acryloyldimethyltaurate / vinylpyrrolidone) copolymer, used as a transdermal penetration enhancer, is as follows (product name: Aristoflex AVC, manufactured by Clariant):
[0045] [ka]
[0046] Furthermore, in Table 1, the structural formula of (ammonium acryloyldimethyltaurate / beheneth-25 methacrylate) crosspolymer as a transdermal penetration enhancer is as follows (note: l:m = 95:5~98:2 (molar ratio), trade name: Aristoflex HMB, manufactured by Clariant):
[0047] [ka]
[0048] Furthermore, in Table 2, the structural formula of (dimethylacrylamide / sodium acryloyldimethyltaurate) crosspolymer as a transdermal penetration enhancer is as follows (note that a:b:c = 80:20:0.1 (molar ratio)):
[0049] [ka]
[0050] Furthermore, in Table 2, the structural formula of the (sodium acrylate / sodium acryloyldimethyl taurate) copolymer is as follows (trade name: SIMULGEL EG, manufactured by Sepic):
[0051] [ka]
[0052] [Table 1]
[0053] [Table 2]
[0054] "evaluation" (Evaluation method) Franz-type diffusion cell (effective transmission area: 0.79 cm²) 2 A receiver cell was filled with 7.5 mL of phosphate-buffered saline (also abbreviated as "PBS"), a skin substitute membrane (Strat-M® (Merck)) was sandwiched between the cells, and the surface temperature was adjusted to 32°C. Strat-M® is one of the commonly used skin substitute membranes for evaluating skin permeability by passive diffusion.
[0055] After hydrating the skin substitute membrane, 10 μL / cm³ 2 The cosmetic compositions of each example and comparative example were applied to the donor cell in the specified volume and spread with a spatula for 30 seconds.
[0056] Then, 1, 2, 3, 4, 6, and 8 hours after the application of each cosmetic composition, 0.3 mL of the receiver solution was sampled and replenished with the same amount of PBS.
[0057] The sampled receivers were quantified by HPLC to determine the amount of niacinamide that penetrated over time in the cosmetic compositions of each example and comparative example. The transdermal penetration rate (%) of niacinamide was then calculated from the obtained penetration amounts using the following formula 1: Transdermal penetration rate of NA (%) = (Amount of NA penetrated / Amount of NA applied) × 100% (Note that "NA" stands for niacinamide.)
[0058] The transdermal penetration rates of niacinamide in Examples 1-4 and Comparative Example 1 are shown in Figure 1, and the transdermal penetration rates of niacinamide in Examples 5-8 and Comparative Example 1 are shown in Figure 2.
[0059] (Evaluation results) As is clear from Figures 1 and 2, it was found that the beauty compositions of Examples 1 to 8 all promoted the penetration of niacinamide (vitamin B group or its derivatives) into the skin compared to the beauty composition of Comparative Example 1 (a composition that does not contain a transdermal penetration enhancer for vitamin B group or its derivatives).
[0060] This is thought to be due to the use of the polymer of the present invention as a transdermal penetration enhancer for vitamin B group or its derivatives in the cosmetic compositions of Examples 1 to 8. In other words, it is suggested that the polymer of the present invention can be used as a transdermal penetration enhancer for vitamin B group or its derivatives.
[0061] Comparative Examples 2-5 In Comparative Examples 2 to 5, when a low-molecular-weight compound having a methyl taurine group was incorporated into the cosmetic composition instead of the polymer of the present invention, the transdermal penetration of B vitamins or their derivatives after 1, 2, 3, 4, 6, and 8 hours was evaluated in the same manner as described above.
[0062] The formulations of the cosmetic compositions for Comparative Examples 2 to 5 are shown in Table 3 below.
[0063] [Table 3]
[0064] As a result, none of the cosmetic compositions in Comparative Examples 2 to 5 showed any effect in promoting the transdermal penetration of niacinamide (vitamin B group or its derivatives).
