Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-sliding cosmetic, a cosmetics water-sliding agent, a cosmetics water-sliding method, and a cosmetics water-sliding providing method, which are characterized by having a water-sliding property and excellent durability of cosmetic effects. The present invention relates to a method for evaluating the slipperiness and water resistance of cosmetics.

2. Description of the Related Art In recent years, for the purpose of improving the durability of sunscreen agents, a technique of blending a water-repellent compound or a water-repellent pigment into a preparation has been used. For example,
As compounds having water repellency, fluorine compounds such as perfluoropolyether, silicone compounds such as dimethylpolysiloxane, and fluorine-modified silicone resins have been used. Further, as the pigment having water repellency, fine particles of titanium oxide treated with silicone or metal soap have been used. These materials have high durability against water and sweat, and the properties of the materials, such as water repellency, have been inherited in the formulations containing these materials. For example, we have reported in JP-A-9-12431 that a cosmetic having excellent durability can be obtained by blending a fluorine-modified silicone resin having high water / oil repellency into the cosmetic. Also,
JP-A-7-126126 reports that cosmetics containing a perfluoroalkyl / polyoxyalkylene co-modified organopolysiloxane and a fluorinated powder have excellent durability. These technologies are technologies constructed based on the composition that “each material is highly water-resistant = the durability of the preparation is increased”.

On the other hand, in recent years, attempts have been made to improve the sun protection performance of sunscreen agents. Technically, it is a continuation of the above-mentioned concept.
As described in JP-A-5808, JP-A-6-135817, JP-A-5-339125, etc., the main technique was how to mix materials having excellent durability. It should be noted that each of these patents only mentions "improving durability" and "improving durability".

[0004]

However, as a result of a long-term field test of a product containing such a material for improving durability, even if the product is supposed to have improved durability, its performance is still high. Was insufficient, and it was confirmed that there was an unexpected problem in durability, especially during bathing. For example, even for a preparation of SPF100 class,
When immersed in water, the ultraviolet protection function may be maintained for only about 2 to 3 hours. For this reason, limitations have been apparent only with the technology for improving durability by combining conventional water-resistant materials. In particular, in the leisure scene, a new technical approach was required in order to provide the preparation with durability such that it would not be sunburned for one day without recoating when applied in the morning.

[0005]

Means for Solving the Problems In view of these problems, the present inventors diligently studied a method for solving the problems. as a result,
For example, for sunscreens, etc.
By newly imparting such performance, it became possible to obtain a sunscreen agent or the like which is less likely to be tanned. This mechanism will be described below. At the water / air interface, the sunscreen coating produces a force that tends to float on the water surface. An effect auxiliary such as a resin component blended into the sunscreen agent works to bind to the skin,
If the effect of the effect aid is strong, the coating of the sunscreen agent is maintained. However, under conditions where a new gas-liquid interface is always formed, such as in a pool or sea bath, products made with the conventional sunscreen design method based on water repellency will gradually deteriorate. It often takes a pattern in which the coating film collapses at a point in time. At this time, as a cause of the deterioration of the coating film little by little, it was considered that the effect adjuvant was compatible with water (weak affinity). That is, it was found that when the effect auxiliary agent had an interaction with water, the coating film was easily affected by water when the gas-liquid interface was formed. Interaction with water is a phenomenon that is observed not only with hydrophilic substances but also with water-repellent substances. For example, when a sample (effect aid) is applied to a glass plate or the like and dipped in running water, water droplets form on the glass surface, etc. Those that remain are thought to have an interaction with water. In contrast, very specific substances exhibit a phenomenon called "slidability". That is, there is no interaction with water,
This is a phenomenon in which no water drops remain even when the test is performed on the above-mentioned glass plate or the like, and water flows down instantaneously. When this mechanism is applied to a sunscreen agent or the like, the interaction with water is weak even if a gas-liquid interface is formed, so that the coating film is less likely to float on the water surface and the durability can be improved. The present inventors have examined about 80 types of compounds conventionally known as effect adjuvants to improve durability, as to whether or not they have lubricity. The present inventors have found that a sunscreen agent or the like containing the compound exhibiting the water-sliding property exhibits particularly excellent durability, and completed the present invention.

[0006] In addition, a study was conducted on the mechanism of obtaining the slipperiness. As a result, countless minute projections were formed on the coating film containing these substances, and the projections embraced the air and caused the phenomenon that water flowed down smoothly. We found what was happening and completed the present invention. Examples of such a water-repellent projection that embraces air and exhibits a water-sliding property include, for example, a “Lotus leaf” and a “Butterfly wing”. In the cosmetic of the present invention, by giving a mechanism for forming such a structure to the preparation, the preparation was able to be provided with a level of durability that could not be obtained by the combination of the conventional water repellent materials.
Furthermore, as a result of the formation of the microscopic projections, it was found that even when the coating film was physically contacted with a towel or the like, the actual contacting area was very small, so that deterioration due to the contact was suppressed. Further, in the present invention, in order to distinguish between the conventional water-resistant cosmetic and the water-slidable preparation, an evaluation index using a glass plate or the like was created and evaluated to clarify the difference from the existing product.

With the above perfluoroalkyl group,
It is obtained by completely or partially substituting hydrogen atoms of an alkyl group having 1 to 10 carbon atoms with fluorine atoms. The polyoxyalkylene group is a polyoxyethylene group, a polyoxypropylene group, or a group of a copolymer thereof. In addition, in order for the cosmetic to have lubricity, in addition to blending the above-mentioned lubricity-imparting agent, the cosmetic is selected by selecting the type and amount of other hydrophobic component and hydrophilic component blended in the cosmetic.

The method of imparting water-slidability to the cosmetic according to the present invention is a technical idea that has never existed before, and has a feature that a cosmetic having high durability such as water resistance and sweat resistance can be easily developed. .

The criteria for determining the slipperiness in the present invention include:
For example, assuming an actual water bath, the sample is, for example, 5 ×
After coating on a 10 cm smooth glass plate or the like at a coating amount of 1 mg / cm ² and drying at 37 ° C. for 30 minutes, a coating film on a glass plate or the like is immersed in water at 40 ° C. for 10 minutes, and then on a glass plate or the like. When running water is passed through the coating film, the water film is visually formed, and the water droplets flow down without water droplets being formed on the coating film, whereby it can be determined that the film has slipperiness. When drying at 37 ° C. for 30 minutes, it is preferable to use a blow dryer. The reason why it was soaked in water at 40 ° C. for 10 minutes is assuming a water bath. Also, depending on the sample, even if the sample does not use running water, it shows water-sliding properties.However, due to its low strength, there are materials that break down the coating film when running water is used. Treated as not. Therefore, it can be said that a sample which is recognized as having a water-sliding property according to this standard has a sufficient film strength in addition to the water-sliding property. In addition, since the present invention is based on the premise that the above evaluation method can be used, W / O type and non-aqueous type cosmetics are preferable, and those in which the coating film is hydrophilic like O / W type are preferable. Not eligible. In addition, after applying and drying the cosmetic on a smooth glass plate, a plate of metal, plastic, or the like, the coating film on the plate was immersed in water for a certain period of time, and then the running water was flowed on the coating film on the plate. The method of evaluating the slipperiness or water resistance of a cosmetic in a state where water drops flow down can be applied as a method of evaluating the slipperiness and water resistance of a cosmetic. At that time, the amount of cosmetic applied, drying conditions, immersion time of the coating film in water, water temperature,
