Detailed Description

The present invention relates to a cosmetic composition containing MQ silicon resin and propyl silsesquioxane resin as effective ingredients, thereby preventing the skin from being dried or tensed and maintaining the skin to be moist.

The present invention will be described more specifically below.

According to one aspect of the invention, the MQ silicone resin is selected from the group consisting of (R)¹ ₃SiO_1/2)_aM units represented by the formula and_4/2)_bq unit shown. The R is¹And may independently be an alkyl group or an aryl group of 1 to 8 carbons. Examples of the alkyl group include methyl, ethyl, propyl, butyl, pentyl, and hexyl, and examples of the aryl group include phenyl, naphthyl, benzyl, tolyl, methylbenzyl, and biphenyl. A and b represent integers exceeding 0, and the ratio of a/b is 0.5 to 1.5. The MQ silicone resin can also contain more than 1 of D units and T units, but more than 80 mol% or more than 90 mol% of the total MQ silicone resin is M and Q units. The MQ silicone resin may be, for example, trimethylsiloxysilicate, but is not limited thereto.

According to one aspect of the present invention, the propyl silsesquioxane resin contains 80% or more of R based on the entire propyl silsesquioxane resin²SiO_3/2The indicated T units. The R is²Independently an alkyl group or an aryl group of 1 to 8 carbons, and 40 mol% or more is propyl. The propyl silsesquioxane resin may also contain 1 or more units selected from M, D, and Q units, but in this case 80 mol% or more of the total propyl silsesquioxane resin remains T units. The propyl silsesquioxane resin may be, for example, polypropylsilsesquioxane.

The M unit, the D unit, and the Q unit are silicon polymer units and can be represented by the following chemical formula 1.

Chemical formula 1

According to one aspect of the present invention, MQ silicone resin may be contained in an amount of 0.01 to 30 wt%, preferably 0.01 to 10 wt%, based on the total weight of the composition. This is because, in the case of less than 0.01% by weight, it does not contribute greatly to the skin moist feeling; in the case where the amount exceeds 30% by weight, the phenomenon of tautness is serious.

According to an aspect of the present invention, the propyl silsesquioxane resin may be contained in an amount of 0.01 to 30 wt%, preferably 0.01 to 10 wt%, based on the total weight of the composition. This is because, in the case of less than 0.01% by weight, it does not contribute greatly to the skin moist feeling; when the amount exceeds 30% by weight, the feeling of use becomes heavy.

According to an aspect of the present invention, the MQ silicone resin and the propyl silsesquioxane resin may be contained in the composition at a weight ratio of 1:150 to 150:1, and may preferably be contained at 1:80 to 80: 1. This is because the use feeling is hindered when the weight ratio is more than the above.

The composition according to one aspect of the present invention may be formulated into a dosage form containing a cosmetically or dermatologically acceptable medium or base material. This is a complete dosage form suitable for topical use and may preferably comprise a type selected from water-in-oil, oil-in-water, oil-dispersed. Also, the dispersion may be provided in the form of a suspension, a microemulsion, a microcapsule, a microparticle sphere or a dispersion of ionic (liposome) and nonionic vesicles, or in the form of a cream, lotion, powder, ointment, spray or concealer stick. Also, it may be used in the form of a foam (foam) or an aerosol composition further comprising a more compressed propellant. These compositions are prepared according to methods commonly used in the art.

The cosmetic composition according to one aspect of the present invention may include, within a range not affecting the object of the present invention, fatty substances, organic solvents, solubilizing agents, concentrating agents, gelling agents, emollients, antioxidants, suspending agents, stabilizers, foaming agents, fragrances, surfactants, water, ionic or nonionic emulsifiers, fillers, sequestering agents, chemical chelating agents, preservatives, vitamins, blocking agents, humectants, essential oils, dyes, pigments, hydrophilic or lipophilic active agents, lipid vesicles or adjuvants commonly used in cosmetics and any other ingredients and the like, which are commonly used in the fields of cosmetics or skin science, which are useful in the art for cosmetics. The adjuvant is introduced in an amount generally used in the field of cosmetics or skin science. Also, the composition of the present invention may contain a substance that promotes skin absorption in order to enhance the skin improvement effect.

Detailed Description

The present invention will be described more specifically with reference to examples. These examples are only for illustrating the present invention, and it is apparent to those skilled in the art that the scope of the present invention is not limited by these examples.

Comparative examples 1 to 3 and example 1

Comparative examples 1 to 3 and example 1 were prepared according to the compositions shown in table 1 below.

TABLE 1

< preparation method >

1) Mixing and dispersing the oily components and the powder.

2) The aqueous components were mixed together.

3) The mixture of 2) above was slowly added to the mixture of 1) above, followed by mixing and emulsification.

4) Completely degassing the mixture of the above 3) to prepare a water-in-oil type cosmetic composition.

Test example 1 sensory evaluation of cosmetic composition

The compositions according to comparative examples 1 to 3 and example 1 were applied to the faces of 20 women aged 25 to 39 years, and after 12 hours, the moist feeling and the absence of skin tightness were evaluated according to a survey, wherein each evaluation criterion was that the maximum of each item was 5 points, the effect was better, and a higher point was given. The average of the scores was taken as the result and shown in table 2 below.

TABLE 2

Evaluation item	Comparative example 1	Comparative example 2	Comparative example 3	Example 1
					Not dry and wet	1.4	1.7	1.9	4.3
Without skin tension	1.3	1.5	1.8	4.2

Among the results of the above table 2, comparative example 2 containing only MQ silicone resin showed low satisfaction with the dry feeling and the tightening phenomenon; comparative example 3 containing only the polypropylsilsesquioxane resin showed low satisfaction with the dry feel and the tightening phenomenon. In contrast, it can be seen that example 1 containing MQ silicone resin and polypropylsilsesquioxane resin shows high satisfaction for all of the evaluation items. Therefore, it can be known that the composition according to the present invention contains both MQ silicon resin and polypropylsilsesquioxane resin to exhibit excellent moisturizing feeling and reduce the phenomenon of tightening.

[ test example 2] evaluation of decrease in Dry feeling and tension

According to the present invention, when MQ silicon resin and polypropylsilsesquioxane resin are used simultaneously, whether the dry feeling and the tension phenomenon are reduced or not is confirmed by a simple experiment. The powder components were dispersed in a silicone resin solution with the composition of table 3 below and the solution was thinly applied to artificial leather and dried for 15 minutes. The dried artificial leather was pulled up, down, left, and right 30 times each to apply physical stimulation, and then the surface of the artificial leather coated with the solution was observed. And a photograph of the surface of the artificial leather is shown in fig. 1.

TABLE 3

Ingredient (wt%)	Comparative example 4	Example 2
			Trimethylsiloxy silicate	95	47.5
Poly (propylsilsesquioxane)	-	47.5
			Titanium oxide surface-treated with alkylsilane	4.00	4.00
Yellow iron oxide surface treated with alkylsilane	0.30	0.30
			Red iron oxide surface treated with alkylsilane	0.10	0.10
Black iron oxide surface treated with alkylsilane	0.07	0.07
			Polymethyl methacrylate	0.53	0.53

From the results of fig. 1, the following can be confirmed: when the surface of the artificial leather was observed after the stimulation was applied thereto, it was confirmed that the outer surface thereof was dried and torn in comparative example 4 using only trimethylsiloxysilicate. I.e. low flexibility is expected to give rise to skin tightening. However, in example 2 using trimethylsiloxysilicate and polypropylsilsesquioxane at a ratio of 1:1, it was confirmed that the surface thereof did not tear or crack and a wet and flexible film was formed.

Industrial applicability

The cosmetic composition according to the present invention provides a silicone resin composition containing MQ silicone resin while being excellent in moisturizing feeling and free from a phenomenon of tautness, and thus can provide a cosmetic capable of maintaining a moist cosmetic state free from drying tautness.
