Description

A cosmetic composition for lips of an anhydrous formulation capable of various coloring {Composition of Anhydrous liquid lip with various color stain}

It relates to a cosmetic composition for lips of an anhydrous formulation capable of various coloring.

The lips are the most mobile part of the body, and because they are always exposed to the outside, it is the best body part for women to express their own colors. Cosmetics for lips are applied to the lips and used for the purpose of giving color and gloss, and additionally, they act to protect the lips from cold or dryness. Consumers who use cosmetics for lips want vivid color and long-lasting lip color without any physical action. In order to meet these needs, lip tattoos and semi-permanent lip procedures, which are plastic surgery with red lips, are sometimes performed, but side effects such as pain, pigmentation, and dermatitis may occur due to negligence in hygiene management. will be.

Anhydrous formulations contain high concentrations of water-insoluble solvents to effectively remove oily impurities. However, there is a problem in that the removal efficiency of the water-soluble substance is low and the feeling of use is not good, so that it is not easily removed from the skin. In the case of the existing anhydrous formulation, the oil has the advantage of preventing moisture from escaping from the lips, but there is a limitation in that only pink color can be applied (Red 218). In a market that requires a variety of colors, it is necessary to develop a cosmetic composition for lips that can be colored in a variety of ways by overcoming the limitations of the formulation.

One aspect is a polyol phase comprising glycerin and butylene glycol; And to provide a cosmetic composition for lips comprising an oil phase comprising beeswax and tribehenin.

One aspect is an aqueous phase comprising glycerin and butylene glycol; And it provides a cosmetic composition for lips comprising an oil phase comprising beeswax and tribehenin. The cosmetic composition may be an anhydrous formulation. In general, since the cosmetic composition for lips is an anhydrous oil-dispersion formulation consisting of oil and wax, when a water-soluble pigment is used, the color expression is low and unstable, so that the pigment is easily separated from the formulation. However, the composition according to an aspect has the advantage of high color expression when applied to the lips because the pigment is not separated from the formulation despite the anhydrous formulation.

The cosmetic composition may include a water soluble dye. The water soluble dye may be used to impart an appropriate color to the cosmetic. For example, the water-soluble dye may be Orange No. 205 (CI 15510), Red No. 227 (CI 17200), Red No. 104(1) (CI 45410), Yellow No. 5 (CI 15985), Yellow No. 4 (CI 19140). , Red No. 102 (CI 16255), Blue No. 1 (CI 42090), or a combination thereof.

The glycerin and butylene glycol may be mixed in a weight ratio of 1:10 to 10:1. The glycerin and butylene glycol are, for example, 1:10 to 10:1, 2:9 to 9:2, 1:6 to 6:1, 2:5 to 5:2, 3:4 to 4:3 , 3:7 to 7:3, or 2:4 to 4:2 may be mixed. At this time, when the mixing ratio of glycerin and butylene glycol is less than the above range, there is a problem in that the formulation is separated, and when it exceeds the above range, there is a problem that the pigment is not well dissolved. In addition, the beeswax and tribehenin may be mixed in a weight ratio of 1:10 to 10:1. The beeswax and tribehenin are, for example, 1:10 to 10:1, 2:8 to 8:2, 3:7 to 7:3, 4:6 to 6:4, 2:9 to 9:2 , 3.5:5.5 to 5.5:3.5, 4.5:5.5 to 5.5:4.5, or 1:1 mixture. At this time, when the mixing ratio of beeswax and tribehenin is less than the above range, there is a problem in that the polyol phase is separated due to low viscosity, and when it exceeds the above range, the formulation becomes too hard and is not suitable as a cosmetic for lips.

The polyol phase and the oil phase may be mixed in a weight ratio of 1:15 to 15:1. The polyol phase and the oil phase are, for example, 1:15 to 15:1, 1:13 to 13:1, 1:12 to 12:1, 1:11 to 11:1, 2:15 to 15:2, It may be a mixture of 2:14 to 14:2, 3:15 to 15:3, or 4:14 to 14:4. At this time, when the mixing ratio of the polyol phase and the oil phase is less than the above range, there is a problem of phosphorus, and when it exceeds the above range, there is a problem in that the formulation is separated.

The cosmetic composition for lips according to an embodiment may be in the form of lipstick, lip gloss, lip tint, or lip lacquer.

The cosmetic composition for lips according to one embodiment also includes additional ingredients commonly used in cosmetics, such as fragrances, fillers, preservatives, neutralizers, sunscreens, sweeteners, vitamins, free-radical scavengers and sequestering agents, and these It may contain any conventional cosmetic ingredient which may be selected from a mixture of

In addition, the cosmetic composition for lips according to an embodiment is used together with other active agents or colorants, and functions such as color (tone) expression, brightness, three-dimensional effect, moisturizing effect, whitening improvement, anti-wrinkle, UV protection, anti-aging and pearl feeling may be to have

Since the cosmetic composition for lips according to an aspect includes a polyol, it is possible to apply a variety of pigments, so various coloring is possible, and by containing a polyol and a wax in a specific ratio, the formulation limit of the anhydrous formulation is overcome, and the application of various colors is possible. It is possible. In addition, since it has a high moisturizing lasting power, it can act to protect the lips from cold or dryness when applied to the lips.

[Experimental example]

Check compatibility between polyol and oil according to the type of wax

The compositions of Examples 1 to 6 were maintained at 70° C. for 10 minutes to determine whether the oil phase and the polyol phase were maintained mixed depending on the type of wax. As a result, in the case of Examples 1 to 3, it was confirmed that the A phase and the B phase were maintained without separation even after 10 minutes, and in the case of Examples 1 to 6, it was confirmed that the A phase and the B phase were separated after about 10 minutes. could check That is, it can be seen that the oil phase and the polyol phase are not separated and ceresin must be excluded in order to maintain formulation stability. In addition, it was confirmed that when beeswax and tribehenin were included in a certain amount, it showed a glossy and adhesive feeling of use. Therefore, a subsequent experiment was performed with respect to the composition of Example 3.

Confirmation of compatibility between pigment and oil according to the polyol mixing ratio

In the compositions of Examples 3 and 7 to 10, it was confirmed whether the pigment was maintained mixed in the oil phase according to the mixing ratio of the polyol.

Example 3 Example 7 Example 8 Example 9 Example 10 Compatibility between pigment and oil according to the mixing ratio of polyol ○ ◎ ○ ○ X

◎ : Transparent and very well mixed

○ : Mix transparently by heating

X: poorly mixed, turbidly mixed

As a result, as shown in Table 3, in the case of Example 7, it was confirmed that the pigment and the oil were transparently mixed very well, and in the case of Examples 3, 8, and 9, when the temperature was 70° C., the pigment and the oil were transparent. mixing could be observed. On the other hand, in the case of Example 10, even though the temperature was set to 70° C., it was confirmed that the pigment and the oil did not mix well or mixed turbidly even if they were mixed. That is, it can be seen that the higher the content of glycerin, the better the pigment dissolves in the oil phase, and the higher the content of butylene glycol, the more the pigment does not dissolve well in the oil phase and becomes cloudy. have.

Confirmation of compatibility between polyol and oil according to the mixing ratio of polyol

In order to check the compatibility of the polyol phase and the oil phase according to the mixing ratio of the polyol, the compositions of Examples 3 and 7 to 10 were maintained at 70° C. for 10 minutes, and then it was checked whether the polyol phase and the oil phase were separated.

Example 3 Example 7 Example 8 Example 9 Example 10 Compatibility between polyol and oil according to polyol mixing ratio ○ X ○ ○ ◎

◎: not separated

○: hardly separated

X : Separated

As a result, as shown in Table 4, in the case of Example 10, it was confirmed that the polyol phase and the oil phase were not separated even after 10 minutes, and in the case of Examples 3, 8 and 9, it was confirmed that almost no separation was achieved. On the other hand, in the case of Example 7, it was confirmed that the polyol phase and the oil phase were separated after 10 minutes. That is, when glycerin is included alone, separation of the polyol phase and the oil phase occurs, but it can be seen that the higher the content of butylene glycol, the better the compatibility with the oil phase.

Formulation stability check

In order to check the formulation stability according to the temperature of the cosmetic composition for lips, the composition prepared in Example 3 was stored for 14 days in a thermostat at various temperatures (25° C., 37° C., 45° C. and cycle) for 14 days and then on the 7th and 14th days. On the first day, changes in appearance were visually observed.
