Description

[0001] The present invention relates to a cosmetic composition comprising a centilla sp. Extract or a triterpene derived therefrom in a high content, and a method for producing the same. [0002] The present invention relates to a cosmetic composition comprising a centella asiatica extract or Triterpene isolated therefrom,

The present invention relates to a cosmetic composition containing a large amount of Centella asiatica selec. Triterpene, which is a poorly soluble plant extract component, or Centella asiatica selec. Triterpene derived from centella asiatica extract. More particularly, (O / W) which can contain tritaper in a high amount and stably in a high concentration and can stably contain Triticum annuum extract-derived tritaper, by dispersing triterpenes with specific polymer polyols at a high temperature, To a cosmetic composition.

The centilla extract, which is a plant extract component, or triterpene derived therefrom is widely used for ointments and cosmetics of medicinal preparations because of its excellent functions such as anti-inflammation, soothing, antibacterial, scar relaxation, promotion of collagen production and whitening effect.

However, tritaperpenes derived from the centilla sp. Extract are generally poorly soluble in water and have low solubility in oil. Therefore, it is difficult to uniformly disperse in cosmetics, especially in oil-in-water cosmetics, There is a great restriction on the use of a high content due to precipitation by the skin,

[Test Example 1] Stability of formulation over time and evaluation of foreign body sensation

The formulation stability and the foreign body sensation of the underwater type cosmetic compositions of Examples 1 to 3 according to Production Example 1 and Comparative Examples 1 to 4 according to Production Example 2 were evaluated.

The time-dependent formulation stability was evaluated by observing with time the changes of the composition of the examples and comparative examples from the time immediately after the preparation to the elapse of time (2 weeks) at room temperature (room temperature), that is, the formation of the formulations, discoloration and precipitation. Table 2 summarizes the results.

The compositions of the examples and the comparative examples were poured into a glass plate (width * length * thickness = 19 cm * 19 cm * 0.3 cm) immediately after preparation to obtain a temporal impression of the formulation (that is, a centipede extract or T. terpenes ) * ASIATIC ACID * homogeneous dispersion of MADECASSIC ACID), and the results are summarized in Table 2.

<Evaluation Criteria for Time Stability>

X: unstable (at least one of the formation of the formulations, the discoloration and the precipitation)

○: Stable (formation of formulations, discoloration, no precipitation

<Evaluation Criteria for Time-Dependent Foreign Objects>

+++: Coated on a glass plate but neat, rarely coarse, occasional foreign body is rarely observed;

++++: The condition applied on the glass plate is clean as a whole, no time-dependent foreign matter is observed;

++ -: The coated state on the glass plate is smooth, some coarse portions are observed, and a temporal foreign body is rarely observed;

- + -: The state of the coating on the glass plate is rough as a whole, and some of the time-dependent foreign matter is observed;

---: The state of the coating on the glass plate is rough as a whole, and the foreign matter feeling over time is observed as a whole

In the case of Examples 1, 2 and 3, a time-dependent foreign matter was not observed at all or rarely observed, and the state of being coated on the surface of the glass sheet was smooth and clean.

On the other hand, in the case of Comparative Examples 1, 2 and 3, the rough surface was present on the surface of the glass plate, but the surface appeared smooth, and the foreign matter could not be confirmed with time. However, in Comparative Example 4, the clove extract or tritaper from the centipede extract was not properly dispersed or dissolved, so that the foreign substance could be confirmed visually, and the coated state on the surface of the glass sheet was rough and uneven (Fig. In comparison with Comparative Example 4 in Fig. 1, it can be visually confirmed that Example 2 according to the present invention shows that tentapenes derived from Centaurea or Centella asiatica are well dispersed or dissolved and stably maintained.

[Test Example 2] Evaluation of precipitation by polarization observation

Since the cosmetic compositions of Examples 1, 2, and 3 and Comparative Examples 1, 2, and 3 were not able to confirm the temporal foreign body sensation of the centilla extract or tritaper from the centipede extract, Polarization (magnification: x400) was taken to confirm the precipitation.

As a result, in Examples 1, 2 and 3, precipitation was not observed at the time of observing the polarized light, but it was confirmed that the compositions of Comparative Examples 1, 2, and 3 had the precipitation of T. periplan 2).

[Test Example 3] Evaluation of the dispersion state of Kunchuk extract by optical microscope observation

In order to confirm the long-term stability of T. terpenes derived from Centella asiatica or Centella asiatica in the cosmetic compositions of Examples 1, 2 and 3 and Comparative Examples 1, 2 and 3, they were sealed at room temperature for 2 weeks after the preparation and then stained with Nikon ECRIPSE 80i (Magnification: 400) using an optical microscope.

As a result, as can be seen from FIG. 3, precipitation did not occur at all in the compositions of Examples 1, 2, and 3, but precipitation occurred in the compositions of Comparative Examples 1, 2, and 3.
