Description

Cosmetic composition for cooling cream with instant and lasting cooling feeling

The present invention relates to a cosmetic composition for cooling cream having an immediate and continuous cooling sensation.

When the skin is repeatedly exposed to heat, skin aging is accelerated, such as a decrease in skin elasticity and an increase in wrinkles. When a normal body temperature person is exposed to intense sunlight for 30 minutes, the skin temperature can rise up to 43 degrees Celsius.

Meanwhile, when the skin temperature rises above 37° C., the number and area of blood vessels are increased due to heat, and collagen fibers and elastic fibers of the skin are rapidly destroyed, thereby accelerating skin thermal aging. This is the same mechanism as photoaging by ultraviolet rays, and since the heat by infrared rays of the sun is longer than the wavelength of ultraviolet rays, the fact that aging by infrared rays appears from deep in the skin can be more fatal.

Therefore, there is a demand for a cosmetic composition containing a cooling sensation that can lower the skin temperature to recover to normal skin temperature after exposure to sunlight, gently soothe irritated skin, and supply sufficient moisture. is a growing trend.

In general, a cosmetic composition for giving a cooling sensation to the skin is prepared by stimulating skin nerves such as menthol or adding a volatile substance such as ethanol. These substances give the skin an immediate cooling sensation, but do not last, and when they are contained in large amounts, they cause skin irritation or dryness, making it difficult to use them on the face.

Therefore, there is a need to develop a cosmetic composition that immediately and continuously provides a cooling sensation without causing strong irritation. In addition, it is urgent to develop a composition that gives a cooling feeling without a volatile solvent to solve skin dryness and at the same time provides a moisturizing effect.

The inventors intensively studied to realize a cosmetic composition formulation for cooling cream by mixing stearylheptanoate and methyldiisopropylpropionamide in an appropriate ratio. As a result, the present invention was completed by embodying a cosmetic composition for cooling cream that immediately and continuously gives a cooling feeling and has a far superior effect of giving a cooling feeling to the skin without drying.

Accordingly, an object of the present invention is to provide a cosmetic composition for cooling cream having an immediate and continuous cooling sensation.

The present invention relates to a cosmetic composition for cooling cream that has an immediate and continuous cooling feeling, and the present inventors have prepared a cosmetic composition for cooling cream that has an immediate and continuous cooling feeling by mixing stearylheptanoate and methyldiisopropylpropionamide in an appropriate ratio. In order to implement a cosmetic composition, intensive research efforts were made. As a result, the cosmetic composition for cooling cream, which is a mixture of stearylheptanoate and methyldiisopropylpropionamide in an appropriate ratio, can effectively lower the temperature of the skin and gives a cooling sensation to the skin without dryness compared to the existing cooling cosmetic composition. It was confirmed that the effect was excellent.

Specifically, 1,2-hexanediol, glycerin, pentylene glycol, and sodium polyacrylate were stirred and dispersed in purified water. Then, polyglyceryl-3 distearate, glyceryl stearate citrate, stearic acid, decyl cocoate and stearyl heptanoate were heated to 70 to 75 ° C. and then introduced using a homo mixer (Homo Mixer) and mixed for 5 minutes at 3000 RPM. Finally, after adding methyldiiospophylpropionamide, the mixture was mixed for 3 minutes at 2500 RPM.

However, Comparative Example 1 did not add methyldiisopropylpropionamide, Comparative Example 2 did not add stearylheptanoate, and Comparative Examples 3 to 5 did not add stearylheptanoate or methyldiisopropylpropionamide compared to Example 1. It was prepared by adjusting the content of as described in Table 2. The rest of the conditions were prepared under the same conditions as in Example 1.

As a result, cosmetic compositions for cooling cream having cream formulations of Comparative Examples 1 to 5 were prepared.

Experimental Example 1. Confirmation of cream formulation formation and homogeneity

In order to determine whether the cream formulations of Example 1 and Comparative Examples 1 to 5 were formed, the appearances of the cosmetic composition formulations were compared and observed (FIGS. 1 and 2).

As shown in Figure 1, Example 1 showed a cream formulation with a sherbet feel.

In addition, as shown in FIG. 2, Comparative Examples 1 to 4 also showed a cream formulation with a sherbet feeling. However, in the case of Comparative Example 5 shown in FIG. 3, while the oil floated on the surface, it was not possible to properly form emulsion particles, and a separation phenomenon was observed.

Therefore, it was confirmed that the mixing ratio of Example 1 and Comparative Examples 1 to 4 was most appropriate in order to realize a feeling of use and properties suitable for cream.

In particular, it was confirmed that the total amount of stearylheptanoate and methyldiisopropylpropionamide was less than 30% by weight in formulating the cosmetic composition for cooling cream.

Experimental Example 2. Evaluation of cooling sensation in Examples and Comparative Examples

Experiments were conducted to evaluate the cooling sensation of Example 1 and Comparative Examples 1 to 4 prepared in a cream formulation.

Specifically, 20 adult males and females (age 30±5) evaluated for sensitive skin were selected, and Example 1 and Comparative Examples 1 to 4 were applied to the back of both hands, and the degree and durability of the cooling feeling felt on the back of both hands Sensory evaluation was performed (Table 3).

Cooling sensation Cooling effect persistence (minutes) Example 1 Strong cooling sensation from the beginning more than 20 minutes Comparative Example 1 A slight cooling sensation at first more than 1 minute Comparative Example 2 After 10 seconds of application, a slight cooling sensation is felt. more than 1 minute Comparative Example 3 Cooling sensation felt weak from the beginning more than 5 minutes Comparative Example 4 Strong cooling sensation from the beginning more than 20 minutes

As shown in Table 3, Example 1 containing both stearylheptanoate and methyldiisopropylpropionamide felt a strong cooling sensation from the beginning of application, and the cooling feeling lasted for more than 15 minutes, so the cooling durability was also excellent.

On the other hand, Comparative Example 1, which did not contain methyldiisopropylpropionamide, felt a slight cooling sensation only at the beginning, and the duration was short. In addition, Comparative Example 2, which did not contain stearylheptanoate, had almost no cooling sensation upon application and only felt a slight cooling sensation for 10 seconds when first applied, but the duration was short. In Comparative Example 3 containing 0.10% by weight of stearylheptanoate and 0.05% by weight of methyldiisopropylpropionamide, the cooling sensation began to feel weak immediately after application when applied, but the duration of the cooling feeling was about 5 minutes. It didn't last long.

The reason why Comparative Example 3 felt a weak cooling feeling was that when stearylheptanoate and methyldiisopropylpropion were mixed, a cooling feeling appeared, but the intensity of the cooling feeling was weak due to the small amount of the two components used, and the cooling feeling did not last long. It was confirmed that no

On the other hand, in the case of Comparative Example 4 containing 25.00% by weight of stearylheptanoate and 3.50% by weight of methyldiisopropylpropionamide, a strong cooling feeling was felt from the beginning of application, and the cooling feeling lasted for 20 minutes or longer.

Therefore, it is confirmed that the cosmetic composition containing both stearylheptanoate and methyldiisopropylpropionamide has a more immediate cooling sensation and superior cooling feeling durability when each stearylheptanoate or methyldiisopropylpropionamide component is included. did In addition, even if both stearylheptanoate and methyldiisopropionamide were included, it was confirmed that there was a difference in the cooling sensation felt depending on the mixing content.

Experimental Example 3. Measurement of skin temperature reduction effect of cooling cream

An experiment was conducted to measure the skin temperature reduction effect of Example 1 and Comparative Examples 1 to 4 prepared as a cream formulation.

Specifically, in order to evaluate the skin temperature reduction effect of the cosmetic composition, 20 adult males and females (age 30±5) evaluated as sensitive skin were selected and placed in a constant temperature and humidity room (22±2 ℃, 40 to 60%) before application. After waiting for 10 minutes at RH), the cosmetic composition prepared according to Example 1 and Comparative Examples 1 to 4 was applied to the inside of the arm (4 cm X 4 cm on the inner side of the lower arm), and then the skin temperature was measured. After obtaining measurement images using an IR camera (IRIS-XP (Gold), MEDICORE, Korea) before application (-5 minutes) and after application, an ROI (Regions of interest) was set within the measurement area and the skin temperature within the ROI was measured. The average value was taken to analyze the temperature change rate of the skin over time (Table 4).

test product Temperature before application (℃) Temperature after application (℃) Skin temperature reduction rate (%) uncoated 25.70 25.70 0.00 Example 1 25.42 24.10 -5.48 Comparative Example 1 25.63 25.55 -0.31 Comparative Example 2 25.62 25.53 -0.35 Comparative Example 3 25.60 24.82 -3.14 Comparative Example 4 25.52 24.15 -5.67

As shown in Table 4, in the skin temperature change, Example 1 showed a greater degree of temperature decrease on the inside of both arms than Comparative Examples 1 and 2. In addition, in the case of Comparative Example 3, the skin temperature decrease rate was lower than that of Example 1, but the skin temperature decrease rate (%) was 3.14%, which was confirmed to be a level at which test subjects could significantly feel a cooling sensation. And, in the case of Comparative Example 4, a skin temperature reduction rate similar to that of Example 1 was exhibited. However, in the case of Comparative Example 4, some test subjects felt skin irritation due to the high content of methyldiisopropylpropionamide.

Therefore, when 0.1 to 25.00% by weight of stearylheptanoate and 0.05 to 3.50% by weight of methyldiisopropylpropionamide were included, there was an effect of reducing skin temperature, and when the two components were 10.00% by weight and 1.00% by weight or more, respectively It was confirmed that a similar effect was shown.
