Hereinafter, the present invention will be described in more detail by way of 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.

Evaluation of skin irritation and feeling of use with oil or not

Evaluation tests for skin irritation and feeling of use were conducted by comparative examples 1 to 3 and examples 1 to 7 in table 1 below.

[ TABLE 1 ]

(1) Evaluation of irritation to skin

Skin patch test was performed on 20 healthy adults, male and female, between 20 and 40 years of age to evaluate the skin irritation of the cosmetic composition. After shaking the compositions of Table 1, a patch test was performed on the back for 48 hours in units of 20. mu.l/chamber. The patch was removed after 1 hour of application and then evaluated for skin irritation at 24 hours and 48 hours, with the results shown in table 3 below. Table 2 is a skin irritation standard score table.

[ TABLE 2 ]

Distinguishing	Skin irritation
		0	No irritation
1	Very weak stimulation
		2	Feeble stimulation
3	Moderate irritation
		4	Strong stimulation feeling

[ TABLE 3 ]

In the case of comparative example 1, which is an oil-free example, most people feel skin irritation. Comparative example 2 is an example using cetyl ethylhexanoate, and the number of people who feel skin irritation is the same as that of comparative example 1 without an oil layer, although oil is contained therein. However, in examples 1 to 7, persons who felt a skin irritation feeling were significantly less compared to comparative examples 1 and 2. From this, it is understood that the degree of skin irritation varies not only depending on the presence or absence of oil but also depending on the type of oil.

(2) Sensory evaluation

The moisturizing and slimy feelings were evaluated for 20 women aged 20 to 30 years. The composition containing vitamin C and the oil layer was mixed with shaking and then applied to the skin for evaluation. Sensory evaluation was performed in 5-part formulation and is shown in table 4 below.

[ TABLE 4 ]

The evaluation criteria were 5 points for excellent, 4 points for excellent, 3 points for common, 2 points for poor and 1 point for poor, and in the evaluation of the sticky feeling, the sticky feeling was rated 5 points for non-sticky feeling and 1 point for sticky feeling. In the evaluation of refreshing feeling, the feeling of refreshing was rated 5 points, and the feeling of no refreshing was rated 1 point.

When the content of vitamin C is higher, the feeling of use is slimy. Thus, in comparative example 1 containing no oil layer, the feeling of freshness was extremely low and the feeling of stickiness was exhibited. In comparative example 2, the moisturizing sensation was insufficient. In comparative example 3, although moisturizing and sticky feeling similar to those of examples 1 to 4 were exhibited, the evaluation of the refreshing feeling was low. However, as is clear from table 4 above, examples 1 to 7 not only had excellent moisturizing feeling, but also had significantly reduced sticky feeling in use, and also exhibited more refreshing feeling in use than comparative examples. In particular, in example 4, the evaluation of the refreshing feeling was extremely high, and it can be seen that an excellent effect is exhibited in improving the heavy, sticky and unclean feeling of use of vitamin C.

Therefore, it is known from the results of the skin irritation test and the sensory test in combination that in order to achieve the reduction of the irritation of vitamin C and the improvement of the sticky feeling in use, which are the objects of the present invention, it is necessary to contain an oil layer and select the type of oil to be used, as described in the present invention.

Further, when the content of an additive for improving a feeling in use is increased in a cosmetic composition containing the same amount of an antioxidant, the content of the antioxidant component contained has to be decreased in order to prevent precipitation or the like of the antioxidant component such as vitamin C. However, when the polydimethylsiloxane or the methylpolytrimethicone is used in combination with the natural oil, the irritation to the skin is low and the feeling in use is good, and at the same time, the amount of the additive can be reduced, so that a product containing a high content of the antioxidant can be provided.

The present invention may provide the following embodiments as examples.

The first embodiment may provide an additive composition for improving a feeling of use of a cosmetic composition containing 15% by weight or more of vitamin C, and the additive composition comprises an additive selected from the group consisting of polydimethylsiloxane, methylpolytrimethicone, hydrogenated C_6-14Olefin polymer, diphenylsiloxyphenyl trimethicone, C_18-21An alkane, and a natural oil.
