Abstract

PURPOSE:To obtain a cosmetic, especially refill of eyebrow pencil having improved feeling in use (soft touch and good spread) and strength by blending a cosmetic comprising a wax such as fats and oils, fatty acids or hydrocarbons, a colorant and an extender with a lysine-based surfactant. CONSTITUTION:A cosmetic (especially refill of eyebrow pencil) comprising a wax such as fats and oils, fatty acids or hydrocarbons, a colorant and an extender is blended with 1-5% based on blended composition of a lysine-based surfactant to give the above-mentioned favorably usable cosmetic having smooth touch to influence feeling in use, good spread and high strength of refill itself.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is based on the addition of a lysine-based surfactant to a cosmetic consisting of waxes such as oils and fats, waxes, fatty acids, and hydrocarbons, colorants, and extenders. The present invention relates to cosmetics with improved usability and strength, particularly eyebrow pencils.

It is obtained by kneading and molding materials, and the strength of the core is adjusted depending on the wax composition.

(Problems to be Solved by the Invention) The eyebrow ink lead obtained in this way emphasizes smoothness and spreadability, which are important for the feeling of use when drawing directly on the skin, and uses soft wax and wax in the wax composition. If the oil content is increased, the strength will weaken and the tip of the core will become more noticeable when used.

On the other hand, by determining the strength of the core rod and using a relatively large amount of hard wax in the wax composition, the strength of the core will be increased and problems such as the sticky feeling during use and the crushing of the tip of the core will be solved, but on the other hand, it will be harmful to the skin. The texture, smoothness, etc. will be lost.

As described above, the relationship between the smoothness of touch and the strength of the core during use is symmetrical, and it has not yet been possible to satisfy both simultaneously.

(Prior art) Conventional eyebrow ink wicks contain waxes, coloring materials, and body compositions (Means for solving the problem) That is, the present invention uses waxes such as oils, waxes, fatty acids, hydrocarbons, coloring materials, and body compositions. Furthermore, by adding a lysine-based surfactant, kneading, and molding, we can improve the smoothness of the touch and the strength of the wick itself without changing the wax composition of conventional eyebrow ink wicks, thereby solving the above problems. It was planned.

(Function) The lysine-based surfactant used in the present invention has a structure in which thin plate-like crystals are laminated, and since the layers easily form folds, it spreads thinly and homogeneously, thereby increasing the strength of the core itself. This improves the smoothness of touch to the skin without deteriorating it.

(Example) The cosmetic composition according to the present invention will be explained in more detail based on the following example.

Note that the number of parts is by weight.

Whale wax, lanolin, and squalane are heated and melted, and iron oxide as a coloring agent and a lysine-based surfactant are added to this and thoroughly kneaded while heating with 3 rolls. An eyebrow ink core was obtained by molding it into a round rod shape.

The obtained lead had a smooth touch with little feeling of sticking when drawn on the skin.

Add titanium oxide, talc, and lysine surfactant 3
The mixture was sufficiently kneaded while being heated with a main roll, and then molded into a round rod shape with a diameter of 3.81° using an extrusion molding machine to obtain an eyebrow ink core.

The obtained lead had a smooth touch with little feeling of sticking when drawn on the skin.

Titanium oxide and talc were added and thoroughly kneaded while heating with a 3-wood roll, and the mixture was molded using an extrusion molding machine to a diameter of 3.
An eyebrow ink core was obtained by molding it into an 8fi round bar.

Table 1 shows the bending strength comparison data.

〔Effect of the invention〕

In the present invention, by adding 1 to 5% of lysine-based surfactant in the formulation, smoothness of touch and spreadability, which affect the feeling of use, are improved, and at the same time, the core itself is strengthened. As a result, a cosmetic composition that is highly desirable for use can be obtained.
