Description

Underwater type oil painting makeup

The present invention relates to an underwater type emulsion cosmetic.

The ultraviolet barrier cosmetic material is intended to cut ultraviolet rays in sunlight and protect the skin from adverse effects caused by ultraviolet rays. Examples of the base include emulsification type, lotion type and oil type, and in the emulsification type, (Continuous phase), and a water-in-oil emulsified cosmetic composition in which an oily component is in a traumatic phase (continuous phase). Conventionally, ultraviolet-shielding cosmetics are required to have a fresh feeling of use. Among the underwater type emulsion cosmetics, since the underwater type emulsion cosmetics emulsified with the hydrophobic ultraviolet scattering agent can suppress tackiness, a fresh feeling can be realized For example, Patent Document 1).

On the other hand, in order to obtain a high SPF (Sun Protection Factor) value by blocking ultraviolet rays from the skin, it is necessary to highly blend a solid UV absorber or an ultraviolet scattering agent with the ultraviolet barrier cosmetic. In order to formulate a solid ultraviolet absorber or an ultraviolet scattering agent, it is necessary to formulate the oil well, but the stickiness can not be suppressed when the oil is mixed and concentrated.

However, in the water-in-oil type emulsified cosmetic material, a high SPF value can be attained without blending the ultraviolet scattering agent by blending dextrin fatty acid ester and / or sucrose fatty acid ester in the oil in Patent Document 2, and the oiliness and stickiness It is described that it is possible to reduce the number of pixels.

Japanese Patent Application Laid-Open No. 2014-101335 Japanese Patent Application Laid-Open No. 2011-126832

In order to realize good freshness and good legibility, it is necessary to reduce the amount of oil, but in order to dissolve the solid ultraviolet absorber and formulate the ultraviolet scattering agent, it is necessary to add the ester oil as an essential ingredient. However, since the ratio of the ester oil in the total oil content is increased, the stickiness of the ester oil is generated. In the case of such an underwater type emulsion cosmetic material, the freshness and spreading required for the feeling of use are good, and the realization of a high SPF value required as an original function of the ultraviolet screening cosmetics is in the relationship of the same. Conventionally, a powder that improves usability has been added to the water phase to give a feeling of smooth running, but there has been a problem that a powdery stain occurs at the time of applying the skin. In addition, since the emulsion tends to become unstable in the emulsification system in which the powder subjected to the hydrophobic treatment in the inner phase (oil phase) is blended, when the fatty acid ester as described in Patent Document 2 is added to the oil phase, the emulsion particles are broken, It is difficult to obtain a mechanism.

Example

Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to these Examples. In the following Examples and the like, the amount thereof is expressed by mass% unless otherwise specified.

An oil-in-water type cosmetic composition having the compositions listed in Tables 1 and 2 below was prepared by a conventional method, and the following measurement and evaluation were carried out.

(Ultraviolet protection effect)

The ultraviolet protection effect was performed using a high-density in vitro SPF measurement system described in Japanese Patent Laid-Open No. 7-167781.

Specifically, a solar simulator (Solar Ultraviolet Simulator Model 600: Solar Light Co.) was used as a light source. The sample was uniformly applied to a Transporter Tape TM (3M Co.) used as a coating material at a coating amount of 2.0 mg / cm 2, dried for 15 minutes, and irradiated with ultraviolet rays. Then, calculation of the transmission ultraviolet spectrum was performed, and the SPF value was calculated.

The SPF values of the cosmetic compositions of the examples and comparative examples calculated by the above method were standardized by the SPF values of the solid oil and / or semi-solid type blended samples, and the SPF values of the solid oil and / or semi- A value of 1 or less was evaluated as B, and a value of 1 or more was evaluated as A.

(Dispersibility in the immediate state)

Immediately after the obtained cosmetic preparation was visually observed, the state was evaluated according to the following criteria.

A: Dispersed uniformly

B: I see a little of the non-dispersed part.

C: Unpartitioned parts are shown

(Stability over time)

The state of the obtained cosmetic after 2 weeks at room temperature was visually observed and evaluated according to the following criteria.

A: Separation is not shown

B: A little separation of oil is seen.

C: Some oil is separated.

The feeling of use of the obtained cosmetic was evaluated according to the following criteria.

(Fresh)

By applying 10 cosmetics by 10 female panelists, it was applied to the skin to evaluate the freshness of the application.

A: More than 8 panelists felt fresh when applying

B: Three to seven panelists felt fresh when applied

C: Less than 2 panelists felt fresh when applied

(Stickiness)

The cosmetics were applied to the skin by ten female panelists to evaluate the tactile sensation after application.

A: More than eight panelists admitted there was no sense of stickiness after application

B: Three to seven panelists admitted that there was no stickiness after application

C: Less than two panelists admitted that there was no stickiness after application

As shown in Tables 1 and 2, the water-in-oil type cosmetic cosmetic of the present invention was able to suppress tackiness as a prescription capable of realizing a high SPF value while maintaining a fresh feeling required for an underwater type oil cosmetic cosmetic. On the other hand, in Comparative Example 1 which does not include a solid oil and / or semi-solid oil, even though it contains fresh, sticky, solid oil and / or semi-solid oil, its blending amount is higher than 25 mass% The amount of the solid oil and / or the semi-solid oil is 2 to 25% by mass based on the total amount of the oil phase, the oil phase is not more than 40% of the total amount of the cosmetic cosmetic, even though the stickiness can be suppressed. If it exceeds the mass%, emulsion breakdown occurs as shown in Comparative Example 3. Further, in Comparative Example 3, since emulsion breakage occurred, the measurement of the SPF value and the sensory evaluation were not performed. In addition, as shown in Comparative Example 4, in the case of palmitic acid dextrin, stickiness could not be suppressed because of the high viscosity as shown in Table 3. Comparative Example 5 is an example using palmitic acid and Comparative Example 6 is a higher alcohol.

(Viscosity measurement)

A sample was prepared by dissolving 2% of each solid oil and / or semi-solid oil, fatty acid and higher alcohol in a solution of 98% diisopropyl sebacate as a solvent. After the sample was allowed to stand for one day, the sample was observed with a B-type viscometer, a VDA-type viscometer DIGITAL VISMETRON VDA) under the conditions of a rotor No. 2 and a rotation speed of 12 rpm for 1 minute. The measurement results are shown in Table 3.
