Description

Easy washable cosmetic composition by Lukewarm water

The present invention relates to a cosmetic composition, and has a high sustainability at the time of makeup, and relates to a cosmetic composition that can be easily erased with lukewarm water at the time of washing.

When cosmetics were applied to the skin, users wanted to stay on the skin for a long time even with a small amount and to maintain the makeup effect for a long time. However, the film or high water resistance products applied to maintain the makeup effect for a long time is difficult to erase easily has a disadvantage of requiring a dedicated cleansing cosmetics. In particular, in the case of makeup and sunscreen products, the hydrophobic polymer used to increase the makeup persistence as described above, there was a problem that it is difficult to erase easily due to the wax with a high melting point.

Japanese Patent Laid-Open Publication No. 2003-134661 proposed a product containing a water-soluble polymer to enhance the cleaning power of the makeup, but since the makeup is easily broken by the sweat and moisture in daily life as it can be easily removed by face-washing, its sustainability is significantly lowered. The problem appeared.

The industry has proposed a product using a semi-crystalline polymer, the crystal is released during cleaning and the cleaning power to try to take advantage of the phenomenon, but after the film formed has a disadvantage that the crystal is not solved quickly because it is not easily erased. In addition, the industry has proposed a product that is easily removed when washing by forming a polymer particle film that is free from lukewarm water by using semi-crystalline polymers and polyhydric alcohols, but it is difficult to commercialize, and has great effects when applied to actual formulations. It was hard to get.

As such, in order to simultaneously pursue the persistence and the cleaning power of the cosmetic, there was a problem that it is difficult to solve only with the polymer material. And, due to the nature of the face makeup cosmetic composition, when the film-forming agent is directly introduced into the formulation and applied to the skin, the polymers remain uneven on the skin, and thus the cosmetic composition does not function properly due to grime and extreme dryness. There was a problem that was not suitable for the skin.

Phyllosilicate, on the other hand, is a thin silicate and has an alkali metal ion or a hydrated exchangeable ion located between the Si-O slope and the layer, and thus the charge is different depending on the thin plate shape. This form causes ionic bonds between particles and is mainly used as a thickener. However, no research has been done to develop temperature sensitive cleaning products using phyllosilicates.

The present invention is to provide a cosmetic composition that is excellent in cosmetic persistence in everyday life, but can be easily erased during cleaning.

The present invention to solve the above problems provides a makeup cosmetic composition comprising a complex consisting of a compound having a phyllosilicate and an ionic hydrocarbon chain. Specifically, the makeup cosmetic composition has excellent cosmetic lasting power in daily life when applying the skin, but can be easily cleaned with lukewarm water so that it can be conveniently cleaned without using a separate cleansing product.

As used herein, "lukewarm water" is understood and used in the art to mean lukewarm water, and is understood to mean water of about 35 to 42 ℃.

Phyllosilicate  By type Nanocomposite hydrogel  Formation evaluation

Melt Bentonite (BYK additives), Talc LCW (Sensient Cosmetic Technologies), Montmorillonite (MBK Mineral Bio Kosmetik), Sumecton SA (Tao Kasei), Laponite (BYK additives), and Holloysite (Sigma-aldrich) at 4% Thereafter, an equivalent amount of 4% Cetyl Sulfate (Nikko chem) was added thereto, and the viscosity change was measured by a viscometer (Brookfield LVT). Viscosity was measured based on a 2% solution of each material and measured at room temperature. Each solution was mixed with Stirrer at 70 ° C. for 10 minutes, cooled to room temperature and measured with a viscometer after 1 hour. As shown in FIG. 1, most of the materials were mixed with Cetyl Sulfate to form a complex, thereby increasing the viscosity. In particular, the viscosity of Laponite and Saponite increased significantly.

Phyllosilicate  Evaluation of Pigment Washing by Type and Temperature

In the previous experiment, Saponite, Montmorillonite, and Laponite, which had increased viscosity of Phyllosilicate and Cetyl Sulfate mixture, were dispersed in water at a concentration of 2% as shown in Table 1 below, and then mixed with 2% Sodium Cetyl Sulfate to prepare a nanocomposite hydrogel. 0.1 g was applied to the plate and dried in air for 1 hour. Thereafter, less than 0.1 g of the lipstick formulation was spread thinly on the nanocomposite hydrogel dry body, and then dried for 6 hours. Subsequently, after dipping in water at 25 ° C., 32 ° C. and 40 ° C. for 30 seconds, the removed and dried areas were measured by image analysis (Image J).

As shown in Table 1, when all the phyllosilicate used sodium cetyl sulfate, it was confirmed that the above-coated lipstick was removed at a temperature of 40 ° C. In the case of Laponite and Saponite, the lipstick was maintained at 32 ° C and completely removed at 40 ° C, which is thought to be due to the complete ionic bond between Cetyl Sulfate and Laponite compared to Montmorillonite. Because the hydrocarbon ions are hydrophobic and stable at room temperature, hydrocarbon ions start to be released at a temperature of 40 ° C, and the laponite absorbs water and swells due to the loosening of the nanocomposite bond.

Pigment Washing Evaluation According to Functional Group of Carbon Compound

The phenomena of cleaning were determined according to the kinds of carbon compounds (Sulfate, Phosphate, trimonium, Dimoinum ionic hydrocarbon chain compounds) that can form ionic bonds with phyllosilicate. As shown in Table 2, nanocomposite hydrogel was prepared by mixing 1% Laponite with 1% Sodium Cetyl Sulfate, 1% Sodium Cetyl Phosphate, 1% Sodium Palmitamidopropyltrimonium, and 1% Sodium Distearidimonium, respectively. Apply and air dry for 1 hour. Subsequently, less than 0.1 g of the lipstick formulation was spread thinly on the nanocomposite hydrogel dry body, and dried for 6 hours. Then, after dipping for 60 seconds in water of 40 ℃ was checked the phenomenon that the lipstick is removed. However, in Example 9, Distearidimonium did not proceed with the lipstick removal experiment due to the precipitation form when mixed with laponite.

As shown in Table 2, when Sodium Cetyl Sulfate and Sodium Cetyl Phosphate were used, it was confirmed that the above-coated lipstick was removed. Sodium Palmitamidopropyltrimoium was hardly erased, similar to the control, but because of the strong bonding of cations on the broad side of the anionic laponite, it was not easy to fall off. Sodium palmityl sulfate and sodium stearyl sulfate were also tested and similar results were obtained. Through this, it was found that the compound having a C 10-20 hydrocarbon chain having anionic property has excellent cleaning power.

With Phyllosilicate  Of compounds having an ionic hydrocarbon chain Particle charge  And size evaluation

Zetapotential measuring instrument (Malvern ZS) was used to measure the zeta potential and size of particles by mixing Lauryl Sulfate with a concentration of 0 to 10 times at a constant Laponite concentration to confirm that the physolilicate and the ionic compound were really combined to form a nanocomposite hydrogel. It was.

As shown in Figures 2 and 3, since the SLS of 0.25 to 2 molar times is added, it is confirmed that the amount of charge of the particles is kept constant at the size of -100 mV and the size of 300 to 400 nm. Rather, the laponite inherent charge is higher than -60 mV and the particle size is smaller than 300 nm, so the nanocomnposite of laponite and SLS is not completely formed.

With laponite Cetyl  Of sulfate nanocomposite  Shape measurement

Laponite and Sodium Cetyl Sulfate were mixed to prepare a nanocomposite hydrogel, and then lyophilized and measured by electron microscopy. As shown in FIG. 4, laponite was agglomerated with nanoparticles having a size of 100 nm and cetyl sulfate was weak in strength, but it was confirmed that the nanocomposite was maintained in a plate shape.
