Abstract

This specification relates to a cosmetic composition for lips that excludes lanolin, which is an animal raw material, and stabilizes a high content of ceramide, enabling sustained moisturization and improvement of dead skin cells on the lips. It contains a lanolin mimetic, and provides moisture function and shielding power at the same time. It can have a superior effect than lanolin, while also complying with the cruelty-free policy.

Description

Cosmetic composition for lips containing ester and/or ceramide {COSMETIC COMPOSITION FOR LIPS INCLUDING ESTER AND/OR CERAMIDE}

Disclosed herein is a cosmetic composition for lips containing ester and/or ceramide.

Moisturizing is largely approached through shielding and moistening. Shielding can be done with polymers or oils, and wetting can be done with polyols.

However, in the case of general stick-type compositions, that is, anhydrous formulations or oil-dispersed cosmetic compositions, in most cases, only shielding is attempted, and when emulsified, the shielding power tends to decrease rapidly.

Accordingly, if there is a paste with hydrating function, that is, a material that both hydrates and shields at the same time, it can be expected that the moisture content will be richer and last longer. A representative substance that can provide moisture and shielding at the same time is 'lanolin', which is an ingredient extracted from sheep's wool and has been used for a long time. However, in accordance with the recent cruelty-free policy, not only are animal tests excluded, but animal ingredients are also excluded from cosmetics, so alternatives are needed.

Meanwhile, most lip keratin care is done through a beauty method that involves soaking the dead skin cells in the lips and then pushing them out with a wet tissue and tearing them off. However, this care can often result in scars as the dead skin cells on the lips are torn off.

In general, lips with healthy keratin have a different ceramide profile compared to lips with a lot of keratin, and to overcome this, cosmetic compositions containing ceramide can be helpful in managing lip keratin. However, most lip cosmetic compositions were stabilized in ppm units due to the precipitation of ceramide.

Therefore, there is a need to develop a composition that has excellent moisturizing properties and can stabilize a high content of ceramide.

Cosmetic composition for lips

In an exemplary embodiment of the present invention, a cosmetic composition for lips comprising at least one of a first part and a second part, wherein the first part includes a first ester, which is an ester compound of a fatty acid having 10 or more carbon atoms and a sterol; An ester compound of a fatty acid having 10 or more carbon atoms and a fatty acid alcohol having 10 or more carbon atoms, or a second ester containing the same as wax, oil or butter; and a third ester, which is an ester compound of a fatty acid with 10 or more carbon atoms and a ground alcohol with 3 to 8 carbon atoms, or an ester compound of a fatty acid with 10 or more carbon atoms and a polyalcohol;　and wherein the second part includes ceramides; and a fatty acid having 14 to 22 carbon atoms. It provides a cosmetic composition for lips containing a.

In another exemplary embodiment of the present invention, a composition comprising at least one of a first part and a second part, the first part comprising: a first ester, which is an ester compound of a fatty acid having at least 10 carbon atoms and a sterol; An ester compound of a fatty acid having 10 or more carbon atoms and a fatty acid alcohol having 10 or more carbon atoms, or a second ester containing the same as wax, oil or butter; and a third ester, which is an ester compound of a fatty acid with 10 or more carbon atoms and a ground alcohol with 3 to 8 carbon atoms, or an ester compound of a fatty acid with 10 or more carbon atoms and a polyalcohol;　and wherein the second part includes ceramides; and a fatty acid having 14 to 22 carbon atoms. It provides a use of a composition comprising at least one of the first part and the second part for preparing a cosmetic composition for managing dead skin cells on the lips.

In Part 1, lanolin is a component extracted from sheep wool and has the characteristic of having both water function and shielding power. However, lanolin, which has beneficial properties for moisturizing, is an animal raw material, and its use is discouraged due to the cruelty-free policy of the cosmetics industry. Accordingly, various raw materials with hydrating functions have been introduced, but their moisturizing effect does not reach that of lanolin.

Accordingly, in the present disclosure, a cosmetic composition for lips is disclosed that combines non-animal ingredients and exhibits superior effects than lanolin while also complying with the cruelty-free policy.

In Part 2, the beauty method of soaking dead skin cells in the lips and tearing them off with a wet tissue often results in scars as the dead skin cells are torn off. Therefore, taking into account the fact that the ceramide profile of healthy lips is different from that of exfoliated (damaged) lips, conversely, if the ceramide profile is normalized using a composition that stabilizes ceramide as in the present disclosure, the dead skin cells of the lips are damaged and ripped off. You can expect that your keratin condition will change to a healthy one without the need to apply it.

On the other hand, cosmetic compositions for lips are most often stabilized in ppm units due to the precipitation of ceramide. In general, in order to stabilize any substance in an oil dispersion formulation, it is advantageous to lower the fluidity of the formulation itself, and it is usually fluid at room temperature. It can be stabilized by adding excess solids or adding high molecular weight polymers. However, in the case of ceramide, the crystallinity is very high, so even if you suppress the fluidity by adding most waxes, the ceramides clump together and quickly form crystals.

Therefore, in the present disclosure, in order to stabilize ceramide, fatty acids other than general waxes, especially C 14 to C 22 fatty acids, such as myristic acid, stearic acid, palmitic acid, arachidic acid, and behenic acid, are used. By including it together, it can contain a high content of ceramide.

In one embodiment, the ceramide may be one or more selected from the group consisting of natural ceramides and similar ceramides.

The natural ceramide may include ceramide 1, ceramide 2, ceramide 3, ceramide 5, ceramide 6, ceramide 7, ceramide 8, etc. that exist in nature. The similar ceramides include HYDROXYPROPYL BISLAURAMIDE MEA, HYDROXYPROPYL BISPALMITAMIDE MEA, Hydroxypropyl Bisstearamide MEA, etc. The pseudo-ceramide refers to a compound having a double-chain lamella structure, which is the structure of natural ceramide.

In one embodiment, the ceramide may be 0.001 to 5.0% by weight based on the total weight of the cosmetic composition for lips. For example, the ceramide content is 0.001% by weight or more, 0.01% by weight or more, 0.1% by weight or more, 0.2% by weight or more, 0.3% by weight or more, 0.4% by weight or more, 0.5% by weight or more, 1 It may be more than 5% by weight, more than 1.5% by weight, more than 2% by weight, more than 2.5% by weight, less than 5% by weight, less than 4.5% by weight, less than 4% by weight, less than 3.5% by weight, less than 3% by weight, less than 2.5% by weight. , may be 2% by weight or less, 1.5% by weight or less, and 1% by weight or less.

In one embodiment, the fatty acid having 14 to 22 carbon atoms may be one or more selected from the group consisting of myristic acid, stearic acid, palmitic acid, arachidic acid, and behenic acid.

In one embodiment, the weight ratio of the ceramide and the fatty acid having 14 to 22 carbon atoms may be 1:5 to 20:1. For example, the weight ratio is 1: 5 to 20: 1, 1: 5 to 15: 1, 1: 5 to 10: 1, 1: 5 to 5: 1, 1: 4 to 4: 1, 1: 3 to 3: 1, or 1:2 to 2:1. If the weight ratio of ceramide and fatty acid exceeds 20:1, for example, 30:1, ceramide may precipitate later due to insufficient fatty acid and may not be stabilized.

In one embodiment, the second part may further include cholesterol. In the present disclosure, cholesterol may be further included in the second part to further stabilize the overall composition.

In one embodiment, the weight ratio of the fatty acid having 14 to 22 carbon atoms and cholesterol may be 1:10 to 10:1. For example, the weight ratio is 1: 10 to 10: 1, 1: 9 to 9: 1, 1: 8 to 8: 1, 1: 7 to 7: 1, 1: 6 to 6: 1, 1: 5 to 5. : 1, 1: 4 to 4: 1, 1: 3 to 3: 1, or 1: 2 to 2: 1.

For example, if the weight ratio of fatty acid and cholesterol is less than 1:10 and cholesterol is excessively included, such as 1:11, the formulation may gel too much and a cholesterol-specific odor may occur. Additionally, if the weight ratio of fatty acid and cholesterol exceeds 10:1 and fatty acid is excessively included, such as 11:1, the precipitation problem may not be solved.

In one embodiment, the weight ratio of the first part and the second part may be 1:5 to 5:1. For example, the weight ratio may be 1:5 to 5:1, 1:4 to 4:1, 1:3 to 3:1, or 1:2 to 2:1.

Referring to the graph in FIG. 1, it was confirmed that formulations mimicking lanolin (samples 1-3) exhibited superior moisturizing retention (3 hours) than samples 4 and 5, which are commercially available lanolin derivatives.

Additionally, as the viscosity and hardness of the formulation increase, the moisturizing effect generally improves. However, according to the example of the present disclosure, although Samples 2 and 3 were in a softer gel state compared to Sample 1, the actual moisturizing ability was confirmed to be superior to Sample 1. In other words, we were able to find a combination that had excellent moisturizing power compared to its properties.

In addition, it was confirmed that when this combination of simulants was selected to create an anhydrous formulation, especially a stick formulation, it showed excellent moisturizing ability without compromising spreadability.

Referring to Figure 2, which shows the change rate after 3 hours of use, it is statistically significant and superior not only to the commercially available lanolin derivative (sample 5), but also to commercial products 1 and 2 targeting lanolin (including lanolin derivatives).

Referring to Figures 3a-3d, it was confirmed that white particles precipitated on the exterior of the stick when ceramide was not stabilized.

Figure 3a is for sample 7 and does not contain ceramide, so no precipitation occurs. Figure 3b is for sample 10, and although it contains ceramide, it can be seen that it is stabilized and ceramide crystals do not precipitate .

In addition, it was confirmed that no precipitation of ceramide was observed in samples 11 to 15, and in the case of samples 8 and 16 to 20, various stabilization methods were applied, but precipitation was visible on the appearance as shown in Figures 3c and 3d. It could be confirmed with the naked eye. In other words, when fatty acids are included in an appropriate ratio or cholesterol is included, ceramide is stabilized and does not precipitate. However, it is known that ceramide precipitation occurs even when stabilizing means such as highly soluble oil, stabilizing paste, gelling agent, or amorphous wax are used. You can.

Additionally, if there is not enough fatty acid, as in Sample 9, ceramide precipitation may occur during long-term storage, and in this case, white granules can be seen precipitating as shown in Figures 3c and 3d.

<Experimental Example 3> Keratin management of lanolin mimetic and ceramide stabilized composition
