Description

Cosmetic composition for lips containing silicone ingredients {COSMETIC COMPOSITION FOR LIPS COMPRISING A SILICONE-BASED RAW MATERIAL}

The present specification discloses a cosmetic composition for lips comprising a silicone-based raw material.

In general, the method used for non-glossy expression in lipstick is to use a large amount of powder (maica, silica, kaolin, etc.) in an oil phase consisting of wax/oil. In this case, a non-glossy expression is possible when applied due to oil absorption of the powder.

However, due to the inclusion of a large amount of powder, the hardness (hardness) of the lipstick is increased, and due to this, when applying the lipstick, the spreadability is deteriorated, and after the lip is applied, the lips are dried due to continuous oil absorption of the powder.

Therefore, it was necessary to develop a lipstick content with improved lip dryness after application, which is easily applied to the lips without a stiff feeling of use even though the lips are not glossy.

When the dispersant is mixed and used in this way, the hydrophilic group of the pigment is connected to the W/O dispersant, and the silicone dispersant is connected to the silicone used to reduce the glossiness to uniformly disperse the pigments and oil in the lipstick contents. In addition, in the case of iron oxide, which is an inorganic pigment, the weight is heavy and has attractive force that attracts each other.When an inorganic dispersant is used together, it prevents the heavy iron oxide from sinking in a high-temperature dispersion system, and the inorganic dispersant located between the iron oxide attracts iron oxide to each other.

In one embodiment, the cosmetic composition for lips further comprises a dispersant, based on the total weight of the cosmetic composition for lips, silicone gel 1 to 50% by weight; 20 to 80% by weight of silicone oil; 0.1 to 20% by weight of silicone powder; 1 to 30% by weight of wax; 0.1 to 15% by weight of pigment; And 0.5 to 10% by weight of a dispersant; It may include.

For example, the silicone gel may be 5% by weight or more, 10% by weight or more, 15% by weight or more, 20% by weight or more, 25% by weight or more, or 30% by weight or more, 45% by weight or less, 40% by weight or less, 35% by weight % Or less, and may be 30% by weight or less.

For example, the silicone oil may be 25% by weight or more, 30% by weight or more, 35% by weight or more, 40% by weight or more, or 45% by weight or more, and 70% by weight or less, 60% by weight or less, 55% by weight or less, or It may be up to 50% by weight.

For example, the silicone powder may be 1% by weight or more, 3% by weight or more, 5% by weight or more, or 7% by weight or more, and may be 18% by weight or less, 15% by weight or less, 13% by weight or less, or 11% by weight or less.

In addition, the sum of the silicone gel, silicone oil, and silicone powder may be 60 to 95% by weight, based on the total weight of the lip cosmetic composition, 65% by weight or more, 70% by weight or more, 75% by weight or more, Alternatively, it may be 80% by weight or more, and may be 90% by weight or less, 87% by weight or less, or 85% by weight or less. When the total amount of the silicone gel, silicone oil, and silicone powder is less than 60% by weight, the spreadability may be expressed glossy, and when the total amount is more than 95% by weight, the lipstick may be applied unevenly and easily broken.

For example, the wax may be 5% by weight or more, 10% by weight or more, or 15% by weight or more, and may be 27% by weight or less, 25% by weight or less, 23% by weight or less, or 21% by weight or less.

For example, the dispersant may be 1% by weight or more, 1.5% by weight or more, 2% by weight or more, or 3% by weight or more, and may be 9% by weight or less, 7% by weight or less, or 5% by weight or less. If the dispersant is less than 0.5% by weight, the amount of the dispersant is less than the added pigment, so that the pigment cannot be effectively dispersed in the oil, and the pigment may be skewed to one side, resulting in a pigment band or lumpy tea, and the dispersant exceeding 10% by weight. In this case, due to the heavy use of the dispersant, the lipstick may be applied thickly or may feel heavy on the lips after application.

In one embodiment, the cosmetic composition for lips may be formulated in the form of a lipstick, and as described above, a synthetic wax and a mineral wax having a low gloss are mixed together to stably maintain the lipstick shape even at high temperatures.

The above-mentioned constituents can be prepared through a treatment process such as heating, mixing and stirring in a conventional manufacturing method to prepare a cosmetic composition for lips. This manufacturing process is self-evident in the light of the skill level of a person skilled in the art.

Hereinafter, the present invention will be described in more detail through the following examples. However, in the following implementations, the scope and scope of the present invention are not limited thereto, but only for illustrative purposes to aid in understanding the present invention.

According to Table 1 below, cosmetic compositions for lips of Comparative Examples 1 and 2 and Example 1 were prepared (content unit: wt%).

Specifically, the raw materials shown in Table 1 below were weighed and dissolved by heating at 95° C., and then stirred with a homogenizer to prepare a mixture. After the obtained mixture was degassed, it was cooled to -20°C to prepare a lipstick-formed lip cosmetic composition. At this time, the homogenizer used T.K Homomixer Mark II, F Model of Kikakyokyo Bridge in Tokyu City.

Using the lipsticks prepared in Comparative Examples 1 and 2 and Example 1, it was observed whether the expression was not glossy.

Specifically, the application property was measured by sensory evaluation when the manufactured lipstick was applied to the lips.The level at which the lips are stiff when applied and the lips are pushed due to the application of the lipstick is indicated by X, and the application level at the level at which the lips are not pushed. Is represented by O.

The gloss was measured using a micro-TRI-gloss device manufactured by BYK Gardner, applied thinly on a parafilm (PARA FILM, American National Can), and the gloss value emitted at an angle of 60 degrees was taken as a measurement value.

As a result of observation, as shown in Table 2 below, it was confirmed that the lipstick of Example 1 has excellent applicability and an advantage of enabling a non-glossy expression without a feeling of dryness.
