BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a make-

The present invention relates to a makeup cosmetic composition in the form of a water-in-oil type, which is a formulation in which a liquid is immediately released upon application, excellent in phase stability, and excellent in water resistance and cosmetic sustainability.

Like the basic cosmetic composition, various attempts have been made to maximize the moisture content in the makeup cosmetic composition. For example, an attempt was made to make an oil-in-water emulsified makeup formulation, but the stability was low and the oil phase and the water phase were easily separated. In addition, a make-up product in the form of a water drop has also been tried, but this also has a disadvantage that it has a weak water resistant structure. In addition, there has also been an attempt to immediately impart a moisture sensation upon application of a cosmetic composition, and liquid phase release formulations have been developed as part of such attempts. Such liquid-phase release formulations are generally prepared in water-in-water type, in which the water phase is instantly released upon application of the cosmetic composition to maximize the sense of moisture. However, in case of underwater type, it has been pointed out that the water resistance is weak and the cosmetic sustainability is greatly reduced. In addition, there has been a limit in that liquid release formulations developed until now are difficult to differentiate visually in color products because the liquid is transparent.

Accordingly, a problem to be solved by the present invention is to provide a water-in-oil type cosmetic composition which is strong in water resistance, excellent in cosmetic sustaining power, And a method for producing such a cosmetic composition.

In order to solve the above problems, the present invention provides a makeup cosmetic composition in a water-in-oil type, comprising a cross polymer having dimethicone as a main chain and an hydrophilic bond group as an emulsifier, In-oil type make-up cosmetic composition of opaque emulsion release formulation and a process for producing the same.

DISCLOSURE OF THE INVENTION The present inventors have found that when a cosmetic composition of the water-in-oil type is used to overcome the disadvantages of the underwater type cosmetic composition, for example, inferior in durability and water resistance and inferior in long-term stability, it is excellent in terms of persistence and water resistance, . In order to overcome this problem, a liquid-phase release formulation was developed.

However, the water-in-oil type cosmetic composition of the liquid release formulation is difficult to maintain the phase stability, and there is a problem that the oil phase and the water phase are easily separated.

After various attempts have been made, a water-in-oil type cosmetic composition containing an inorganic pigment containing a cross polymer containing dimethicone as an emulsifier as a main chain and a hydrophilic bonding group as an emulsifier has been developed, and accordingly, And further, since opaque fluid is released, it is visually discriminated, and the present invention has been completed.

Hereinafter, the present invention will be described more concretely.

In the present invention, the term "liquid-phase release formulation" means that, when applying the cosmetic composition, the shearing force generated by application or rubbing of the cosmetic composition ruptures the structure of the water-in-oil type so that the inner aqueous phase is exposed in the form of water drops ≪ / RTI > The term "water drop (droplet) form" is only intended to describe the shape (form) of the aqueous phase to be released, and does not mean that the constituent of the aqueous phase is limited to water. The site to which the cosmetic composition is applied may be determined depending on the specific use of the cosmetic composition and may include a non-fibrous keratin material of the human body, for example, skin, mucous membrane or nail, It is common that the phase is exposed in the form of droplets.

Experimental Example  1. Stability and emulsion test

The stability of the cosmetic composition prepared according to the above-mentioned method and an experiment for confirming the release of a liquid (opaque liquid) were carried out. The stability test was confirmed by the presence or absence of changes in 40 to 4 weeks. The test for confirming the release of the opaque liquid was confirmed by observing whether opaque water droplets were formed on the skin when the sample was applied to the skin.

As a result, the stability of the examples was particularly excellent, and furthermore, the phenomenon of opaque liquid emission was confirmed only in the examples. This is because the cross-polymer used as the emulsifier wraps around the inner surface of the water-in-oil type emulsion composition and is expected to release the water component in the form of water droplets as the structure is broken when the friction is given. In this case, It is anticipated to help form opaque water droplets with stability enhancement effects by, but not limiting to, the present invention.

In Table 3 and Table 4, the stability indicates that the stability is excellent in the order of X < DELTA < O and means the stability of formulation against phase separation and the like. In addition, with respect to opacifying liquid discharge, X indicates no opacity liquid discharge, O indicates opaque liquid discharge, and Y indicates clear liquid discharge.

Experimental Example  2. Cosmetic Property Evaluation Experiment

The equipment analysis and sensory evaluation of cosmetic properties were carried out.

Comparative Example 7 (water-drop type (O / W) water drop formulation) was prepared according to Table 5. More specifically, the water component, ion blocker and preservative were added to the water tank and heated to 60, , And the emulsifier was slowly added thereto. Pigment was added and completely dispersed. An oil component and an ultraviolet screening agent were put in an oil bath and the ingredients were completely dissolved in 60. Then, the ingredients were added to a water tank in which pigments were dispersed and emulsified with a homomixer to prepare an underwater type foundation emulsion.

The stability of Comparative Example 1 and Comparative Example 3 was poor and the evaluation was carried out within 3 days after the production.

The water resistance test was carried out as follows. L-value (color difference meter, JCS-10) was measured after applying cosmetics between the elbows and the wrists (2 cm in length and width). After washing for 30 seconds with flowing water, the water was shaken off and the liquid was completely removed by pressing once with the tissue, and the L value was measured. The L value was measured at three arbitrary points on the application site and the average of the measured values was recorded.

The skin temperature was measured three times each using SPOT THERMOMETER (TA-0510F, Minolta) before and after the make-up, and the difference was recorded.

The sensory evaluation of the sensation of cooling sensation, the makeup persistence evaluation and the overall product satisfaction were investigated according to the 5 point scale method for 20 consumers in 20-30 age group.

** Temperature difference before and after application of skin (20 ~ 20 consumers in their 30s)

*** Consumer evaluation on a 5-point scale (20 consumers in their 20s ~ 30s)

As a result, Comparative Example 7 showed a weak water resistance due to the characteristics of the liquid release formulation and the water type. In the case of the cooling sensation confirmed through the temperature difference before and after the application of the skin, the content was correlated with the content of the water phase. However, Example 1 showed the best result in the sensory evaluation of the cooling sensation. This is because the opaque liquid is directly applied to the skin and is thought to be an effect due to the visual cooling feeling, but such judgment does not limit the present invention. In addition, it was confirmed that Example 1 showed the highest value even in make-up persistence and overall satisfaction.
