Abstract

The present invention relates to a cosmetic composition comprising capsules or beads, wherein the composition according to one aspect can effectively improve the stability of capsules and can be stably formulated into a stick-shaped form.

Description

Cosmetic composition comprising capsules or beads

It relates to a cosmetic composition comprising a capsule or bead.

Capsules or beads are widely used in cosmetic compositions because they not only make the cosmetic look more beautiful, but also provide a sense of luxury and allow lipophilic active ingredients to be stably inserted into the capsules.

However, if these capsules or beads sink to the bottom, it may be perceived as a decline in the quality of the product, which may lead to complaints from consumers, and when used, the active ingredients in the capsules may not come out or may come out in excess, causing skin irritation.

Accordingly, much research is being conducted on technologies that can stably disperse these capsules or beads within a composition.

One aspect provides a cosmetic composition comprising a thickener comprising a hectorite compound; a carbonate compound; capsules, beads or a combination thereof; and an oil.

As shown in FIGS. 3 and 4, in Experimental Examples 1 and 2 using a hectorite compound as an inorganic thickener, it was confirmed that the capsules were stabilized in the composition not only immediately after stirring but also after 10 minutes or more after stirring. On the other hand, in the case of Experimental Example 3 using a non-hectorite compound as an inorganic thickener, the capsules were stabilized in the composition immediately after stirring, but it was confirmed that the capsules were not stabilized in the composition but sank after 10 minutes or more after stirring. In addition, in the case of Experimental Examples 4 and 5 using an organic thickener, it was confirmed that the capsules were not stabilized in the composition immediately after stirring but sank.

As shown in Table 2 and Figures 1 to 4, it was confirmed that the inorganic thickener significantly improved the thickening effect of the capsule compared to the organic thickener. In particular, in the case of hectorite compounds, it was confirmed that the oil dispersion effect of the capsule was significantly improved compared to other inorganic thickeners.

As shown in Fig. 5, it was confirmed that the composition including the hectorite compound and the carbonate compound through the above manufacturing examples 1 and 2 significantly improved the stability of the capsule.

In particular, while Manufacturing Example 2 caused color bands to occur on the surface of the formulation, it was confirmed that the problem of color bands occurring was improved in Manufacturing Example 1, which includes stearalkonium hectorite among hectorite compounds, and thus could be effectively formed into formulations such as lipstick.

These results mean that not only have a significantly superior capsule stabilization effect compared to Preparation Examples 3, 4, 6, 7, 8, and 11, but can also be effectively molded into a lipstick formulation.

These results mean that Manufacturing Example 1 not only has a significantly superior capsule stabilization effect compared to Manufacturing Examples 5, 7, 9, and 10, but can also be effectively formed into a lipstick formulation.

Figure 8 is an image comparing the capsule dispersion of a composition containing a hectorite compound or a carbonate compound according to one specific example.

As shown in Fig. 8, in Preparation Examples 3 and 4 not including propylene carbonate, Preparation Example 6 including 0.60 wt% of a hectorite compound relative to the total weight of the composition, Preparation Example 7 including 1.00 wt% of a carbonate compound relative to the total weight of the composition, and Preparation Example 11 not including a hectorite compound, the thickening effect was weak, resulting in a phenomenon in which capsules clumped together. These results imply that Preparation Example 1 not only has a significantly superior capsule stabilization effect compared to Preparation Examples 3, 4, 6, 7, and 11, but can also be effectively formed into a lipstick formulation.

The results of Example 2 above are summarized in Table 8 below.

ingredient Manufacturing example 1 Manufacturing example 2 Manufacturing example 3 Manufacturing example 4 Manufacturing example 5 Manufacturing example 6 Capsule stability ○ △ X X X X ingredient Manufacturing example 7 Manufacturing example 8 Manufacturing example 9 Manufacturing example 10 Manufacturing example 11 Capsule stability X X X X X

※ The standards for capsule stability are as follows:

○: Capsules are well dispersed

△: Capsules are well dispersed, but color bands are formed.

X: Weak increasing effect, decreased hardness, capsule clumping, collapse, breakage or cracking

As shown in Table 8, the above results imply that a composition including both a hectorite compound and a carbonate compound can significantly enhance the stabilization effect of the capsule and significantly improve the stability of the formulation.

Example 3. Experiment to measure cutting hardness after molding

Manufacturing Examples 1, 5, 7, 9 and 10 manufactured in the above Example 2 were molded into a lipstick formulation, stored in an incubator at -25°C for one day, and then measured using a RHEO METER (FUDO). The results are shown in Table 9.

- Cutting hardness (N) Intrusion rate Manufacturing example 1 130 ~ 145 48 ~ 50 Manufacturing examples 7 and 9: Products with collapse 40 ~ 70 18 ~ 25 Manufacturing examples 5 and 10: Products with cracks and breakage 300 ~ 350 90 ~ 120

※ The measurement conditions are as follows.

Cutting speed: piano wire, 2 kg, 30 cm/min, 15 mm depth;

Penetration: 1 mmФ 200 g, 30 cm/min, 10 mm depth;

Measurement temperature: 25 ℃;

Measurement after maturation for 1 day in the incubator

As shown in Table 9, low cutting hardness values and low penetration values were confirmed in Manufacturing Examples 7 and 9. In addition, high cutting hardness values and high penetration values were confirmed in Manufacturing Examples 5 and 10.

The above results confirmed that the above Manufacturing Example 1 was very suitable for forming into a formulation such as lipstick in terms of cutting hardness and penetration compared to Manufacturing Examples 5, 7, 9, and 10.
