Description

TECHNICAL FIELD The present invention relates to skin cleansing compositions.

In the past, there were several problems with the act of taking a low-viscosity cleansing agent, such as lotion, and applying it to an object. The viscosity is low, so even if you pick it up, it will spill out and stain the surrounding area before you put it on. Also, it is difficult to apply the stain evenly over a large area, and it is not possible to remove the stain evenly. To solve these problems, a conventional method has been used in which a carrier such as a sheet or cotton is first impregnated with the impregnation and then wiped off with the impregnation. In addition, preparations have been made such as foaming or adding shape-retaining properties using polymers and the like.
For example, Patent Document 1 describes a cleansing product that contains water, a nonionic surfactant, polyaminopropyl guanide, and a polyhydric alcohol, but does not contain ethanol or contains 5% by mass or less of ethanol. It is described that a cleansing sheet in which a sheet base material is impregnated with a composition has high cleansing power and excellent antiseptic power for foundations.

International Publication No. 2015/125332

In recent years, products such as foundations and sunscreens are required to have long-lasting effects, and technology is being developed to form coatings with high water resistance and sebum resistance. The technical idea behind these is that by incorporating film-forming polymers such as trimethylsiloxysilicate (TMS) into the formulation, a durable coating with high water and oil repellency can be created after application. It forms a film.
Since such film-forming polymers are oil-soluble, once a film is formed on the skin, it is difficult to remove it with a water-based cleanser such as a facial cleanser. Therefore, it is generally recommended to remove it with an oil-based cleansing agent. However, cleansing agents that use oil as a cleaning base often become slimy and take a long time to rinse off, and often leave a sticky residue even after being rinsed off.

In real life, foundation and sunscreen are not only applied to the face. There are stains that are difficult to remove on the hands and body, such as foundation temporarily applied to the back of the hand when applying makeup and sunscreen applied to the neck and arms, and wax that gets on the hands after getting your hair styled is also recognized as a stain that is difficult to remove. has been done.
In particular, in the past, people did not routinely apply waterproof sunscreens containing film-forming ingredients that are difficult to remove over large areas of the body, but in recent years, the harmful effects of climate warming and ultraviolet rays have become well known. As people grow older, adults and children alike have become accustomed to applying sunscreen when going out. In particular, as temperatures rise, more and more water-resistant, long-lasting formulations that do not wash off with sweat are being used, and there are increasing complaints that they cannot be easily removed.

Under these circumstances, cleaning agents that can be used for hands and bodies are general cleaning agents such as body shampoo and hand soap. Since these formulations are mainly formulated with anionic surfactants, they do not have enough cleaning power to remove long-lasting foundations and sunscreens. On the other hand, oil-type cleansers leave a sticky feeling during and after use, making them unsuitable for use on areas other than the face. In addition, conventional cleaning agents had limitations in terms of location, as they could only be used in areas where they could be rinsed away with water.
Therefore, it is conceivable to use, for example, a cleansing sheet impregnated with the above-mentioned aqueous cleansing composition for cleaning hands and body other than the face.

However, conventional water-based cleansing compositions have not been able to exhibit sufficient cleaning power for foundations and the like with high film-forming properties.
Furthermore, assuming that the body gets dirt that is difficult to remove in daily life, it would be uneconomical to have to use a single sheet even when you want to remove foundation from your fingertips that has gotten on when applying makeup. be. On the other hand, if you use cotton soaked with sunscreen, you will have to use multiple layers when you want to remove sunscreen from large areas of your body, such as your arms, which is cumbersome.
In this way, it is easy and convenient to impregnate a sheet or cotton with cleaning liquid, but when considering the use of body cleaning where the usage situation and size of the place changes, it is not rational. It is hard to say that it is a product form.
On the other hand, thickened formulations that are not used by impregnating sheets or cotton have problems such as not being able to spread over a large area, leaving the skin sticky and making it difficult to wash them off.
As described above, the present inventors have discovered that there is a latent need for a product that does not feel slimy and can be used to easily remove hard-to-remove stains from the hands and body with just the right amount.

By combining a specific nonionic surfactant with an HLB of 13 or higher with a specific preservative compound, the present inventors have achieved a (specifically) high cleaning effect for foundations and sunscreens with increased sustainability. It has been found that it is possible to provide an aqueous skin cleansing composition that has a good skin feel after use, while maintaining temperature stability suitable for practical use. Furthermore, by storing the skin cleansing composition in a spray container and using it, it is possible to freely and efficiently clean from small to wide areas such as fingertips, arms, and the body, and it is easy to use. I found it.

Relating to skin cleansing articles.

The skin cleansing composition of the present invention can be used against long-lasting foundations and sunscreens containing film-forming ingredients (film-forming stains) without becoming sticky, and has high cleaning power (removal potential). However, it has good temperature stability. Moreover, by storing it in a spray container and spraying it directly onto the skin, it can be freely and uniformly sprayed (applied) from the fingertips to the whole body for efficient cleaning, making it easy to use.

In the present invention, the removal potential refers to, for example, when a long-lasting makeup cosmetic applied on a pseudo skin model substrate in an example is removed by applying a predetermined physical force under certain physical conditions. Refers to removal performance. It is calculated as a removal rate by measuring the color difference before and after cleaning the makeup cosmetics on the model substrate. Further, in the examples, those with a removal rate of 50% or more are considered to have removal potential.

The skin cleansing composition of the present invention can further contain, in addition to the above-mentioned components, components used in ordinary cleansing compositions. For example, polyols other than those listed above, surfactants other than those listed above; aromatic alcohols such as benzyl alcohol and benzyloxyethanol; cellosolves such as ethyl cellosolve and butyl cellosolve; carbitols such as ethyl carbitol and butyl carbitol; sugars Moisturizing ingredients such as (derivatives), amino acids (derivatives), animal and plant (protein) derivatives, and animal and plant extracts; silicone derivatives such as polyoxyalkylene-modified silicones; polymer compounds; sodium sulfate, sodium carbonate, sodium hydrogen carbonate, potassium chloride, Inorganic or organic salts such as sodium chloride and sodium citrate; pH adjusters such as acids and alkalis; anti-inflammatory agents such as glycyrrhetinic acid, glycyrrhizic acid and their derivatives; bactericidal agents such as isopropylmethylphenol; preservatives, metal ions Coloring agents such as sequestering agents, antioxidants, ultraviolet absorbers, fragrances, vitamins, natural pigments, and tar pigments are included.

In the skin cleansing composition of the present invention, the aqueous liquid composition containing the above-mentioned components (A) to (D) is prepared by measuring out components other than water of component (D), heating to 60°C, and stirring. After mixing, it can be produced by cooling while gradually adding water.

The viscosity of the aqueous liquid composition is set at 5°C, considering its usability in a wide range of living temperatures, since it is used by filling it into a spray container and discharging it from the container. The viscosity at is preferably 20 mPa·s or less, more preferably 15 mPa·s or less, even more preferably 10 mPa·s or less.
In the present invention, the viscosity is measured using a B type viscometer (TVB-10M type viscometer, manufactured by Toki Sangyo Co., Ltd.), and when the viscosity is less than 100 mPa·s, the rotor No. Measurement is performed at M1 (rotation speed) of 60 rpm and measurement time of 1 minute.

The skin cleansing composition of the present invention is a transparent liquid phase at 25°C. Here, the term "transparent liquid phase" means that it has a transparent appearance with no separation, and that each component is uniformly dissolved in each other. In such a state, the removal potential becomes high.
Additionally, when the surfactant forms a higher-order association structure, the appearance may become translucent, but in this case as well, it is considered to be a one-liquid phase. When the system separates into two phases, the appearance becomes cloudy white or becomes two-layered, making it difficult to obtain the above-mentioned performances as designed.

In the present invention, an aqueous liquid composition containing components (A) to (D) is stored in a spray container and sprayed directly onto the skin, thereby allowing it to be applied uniformly from a narrow area to a wide area. It can be sprayed (coated) on and cleaned.

Any spray container may be used as long as it can spray the skin cleansing composition in the form of foam, mist, minute droplets, etc. For example, a trigger type (equipped with a trigger type dispenser device) spray container may be used. , pump-type (with pump-type dispenser device) spray containers, aerosols, and the like. Among these, trigger-type spray containers are preferred from the viewpoints of general consumer awareness, ease of use, economic efficiency, environmental compatibility, and the like.
In the spray container, the spray nozzle preferably has a diameter of 0.2 to 0.5 mm, more preferably 0.3 to 0.45 mm, from the viewpoint of the spread of the liquid to be discharged and the discharge efficiency.

Further, the spray container is preferably a mist discharge type spray container (mist container), and from the viewpoint of applying just enough to the target area, the amount of spray per time is 0.2 to 0.7 mL. The amount is preferably 0.3 to 0.6 mL, more preferably 0.3 to 0.6 mL.

When it is assumed that the skin cleansing composition of the present invention is used by spraying it on the arm, it is preferable that the spread of the liquid (composition) when sprayed from a distance of 12 cm is 10 cm or less in diameter. If the size is larger than that, the amount of liquid that will miss the target will be large and will stain the surrounding area. Further, assuming that the amount sufficient for use on one arm is 2 g, the number of times of ejection is preferably 10 times or less. If it is more than that, it will become more of a hassle.
Furthermore, under usage conditions where liquid must be discharged many times, it is assumed that continuous spraying will be performed at high speed. If such an action is taken, the trigger or pump portion of the spray canister will be half-depressed. Considering this situation, we calculated the ratio of the amount of liquid that is dispensed (per time) when dispensing quickly (discharging 5 times in 2 seconds) and the amount of liquid that should originally be dispensed (per time). In terms of ejection efficiency, it is preferable that the ejection efficiency is 50% or more. Less than 50% means that the pressing force is too high, the return is slow, and the trigger is only pulled halfway, or the pump is not pressed. Such behavior is inefficient and gives the user a feeling of heavy usage, which is not desirable.

The skin cleansing composition of the present invention is stored in a spray container and can be used by spraying it directly onto the skin, wiping it off, or washing it off. It can also be sprayed directly onto the skin, allowed to absorb, and then wiped off or washed off. Among these, a method of applying the skin cleansing composition and wiping it off with tissue paper, paper towel, etc. is preferable because it can effectively remove dirt without wasting the cleaning solution.

When applying a cleansing composition with low viscosity to the skin, it is common to use it after impregnating it in a carrier such as a sheet or cotton. The amount of liquid that acts on stains decreases.
However, with the method of the present invention, in which the liquid is stored in a spray container and sprayed directly onto the skin to blend with the dirt and then wiped off, the low viscosity liquid tends to penetrate between fine irregularities, and on the other hand, the liquid does not directly act on the dirt. There is no waste. After blending, the lifted dirt is wiped away to achieve high cleaning performance.
On the other hand, the method of impregnating a sheet or cotton and wiping it off is a useful method for thoroughly cleaning a structure with a constant area and large irregularities, such as the face, but the present invention is preferably applied in situations such as It may be used to remove foundation applied to the fingertips to apply makeup, or to remove sunscreen applied to large, flat areas of the body such as the arms and neck. Therefore, when the same product is used for both situations, the priority is to be efficient without waste and provide high cleaning power. From this point of view, it would be useful for consumers to use the product in a way that allows them to easily adjust the amount of liquid sprayed.

The skin cleansing composition of the present invention can also be used by spraying a sheet or cosmetic cotton to impregnate it, applying it to the skin, and wiping off make-up and the like.
The skin cleansing composition of the present invention can be sprayed on the skin and then wiped off or washed off to clean the skin.
Furthermore, the skin can be cleaned by spraying the skin cleansing composition of the present invention onto the skin, letting it blend in, and then wiping it off or rinsing it off.

Example A, Comparative Example A

Spread of liquid: A mist was sprayed once from a distance of 12 cm onto a wall covered with newspaper, and its diameter was measured. Measurement was performed three times and the average value was determined.
Liquid volume during high-speed discharge: The volume of liquid discharged was measured when the liquid was discharged five times at a high speed of 2 times/second into a plastic container placed on a balance. Measurement was performed three times and the average value was determined.

Examples 16-19
In the same manner as in Example A, a skin cleansing composition having the composition shown in Table 7 was produced, and its removal potential, lack of sliminess during use, and appearance were evaluated, and the 5°C viscosity was measured. The mist discharge performance was evaluated. The results are also shown in Table 7.

(5) Viscosity:
After each skin cleansing composition was left in a constant temperature bath at 5° C. overnight, the viscosity was immediately measured using a B-type viscometer at room temperature. The measurement was performed using a digital viscometer model TVB-M10 (manufactured by Tokai Sangyo Co., Ltd.), spindle M1, 60 rpm, and 1 minute.

(6) Mist discharge performance:
Each skin cleansing composition was placed in a spray container (trigger spray dispenser C) and dispensed several times. The state of the liquid discharged at that time was visually observed.

Test example 1
A skin cleansing composition having the composition shown in Table 8 was prepared and placed in a spray container (trigger spray dispenser C), and the removal potential for sunscreen product A containing a film-forming polymer or sunscreen product B not containing a film-forming polymer was prepared. was evaluated. The results are shown in Table 9 when using sunscreen product A and in Table 10 when using sunscreen product B.

(7) Sunscreen removal potential:
0.05 g of sunscreen was applied to an area of 5 cm x 10 cm on a black artificial leather sheet (manufactured by Okamoto Kaseihin Co., Ltd., Laforet Black) cut into 7 cm x 12 cm, and dried for 6 hours or more.
The sunscreens include Kao Biore UV Kids Pure Milk SPF50, PA+++ (sunscreen product A) as those containing film-forming polymers, and Kao Curel Day Barrier UV Lotion (emulsion type) SPF50+, PA+++ (sunscreen product A) as sunscreens that do not contain film-forming polymers. Sunscreen product B) was used.
The skin cleansing composition prepared in Table 8 was applied to this sunscreen application sheet using two methods: (i) applying it and then wiping it off, and (ii) impregnating the sheet (a dry nonwoven fabric separate from the sunscreen application sheet). The removal potential was evaluated by the wiping method. At that time, the sheet used in (ii) was evaluated by spraying the liquid 2 times (1 mL), 4 times (2 mL), and 16 times (8 mL).

(i) How to wipe off after blending:
After spraying the skin cleansing composition twice (equivalent to 1 g) onto the sunscreen application sheet, divide the sunscreen application surface into 6 parts and apply approximately 150 to 200 g of force to each with two fingers in a circular motion. Rub it around three times at a time. Thereafter, the coated surface was divided into two parts and wiped once with a dry nonwoven cloth (the same as in (ii)) at a weight of 150 to 200 g to remove the liquid component on the sheet.
(ii) Method of impregnating the sheet and wiping it off:
An impregnated sheet was prepared by spraying the skin cleansing composition a predetermined number of times onto a nonwoven fabric cut into a size of 15 x 20 cm ² and letting it soak overnight. The nonwoven fabric used was made of cotton/rayon/PET=50/30/20 and had a basis weight of 45 g/m ² .
The sunscreen-applied surface was divided into two parts and wiped off with a force of 150 to 200 g five times on each side, changing the sides using an impregnated sheet folded in four.
The amount of residual sunscreen is defined as the whiteness derived from the UV scattering agent contained in the sunscreen, and the removal rate is calculated by measuring the color difference (L, a, b value) before application, after application, and after wiping and cleaning. , expressed as a relative value based on the removal rate of sunscreen removed by method (i). In addition, the degree of remaining whiteness was visually observed.

Table 9 shows the results using sunscreen product A containing film-forming polymers.
The relative removal rate of the skin cleansing composition of Example 15 was measured, setting the sunscreen removal rate as 1 when evaluated by the method (i). As a result, when a sheet was impregnated and wiped off, most of the liquid was absorbed by the sheet and did not work when sprayed two or four times, resulting in poor cleaning power. In order to obtain the same cleaning power, 16 sprayings were required, which was inefficient. Also, in the appearance evaluation, the whiteness was not noticeable with method (i), but the whiteness was noticeable when the sheet was sprayed two or four times.
On the other hand, when the cleaning solution of Comparative Example 9 was evaluated by the method (i), the cleaning rate was also poor and the whiteness was noticeable.

Table 10 shows the results using sunscreen product B, which does not contain film-forming polymers.
The relative removal rate of the skin cleansing composition of Example 15 was measured, setting the sunscreen removal rate as 1 when evaluated by the method (i). As a result, when a sheet was impregnated and wiped off, the sheets sprayed 2 times, 4 times, and 16 times all showed relatively high removal rates, and the whiteness was not noticeable. Furthermore, when Comparative Example 9 was evaluated using method (i), it was found that sunscreen product B was sufficiently removed. That is, sunscreens that did not contain film-forming polymers were not affected by method or formulation.

Prescription example 1
In the same manner as in Example A, skin cleansing compositions having the compositions shown in Table 11 were prepared and placed in spray containers.
The resulting skin cleansing composition has high removal potential, good temperature stability, does not leave the skin sticky after use, and can be used by spraying directly onto the skin from a spray container, allowing it to be used on small to large areas. It can be sprayed freely and evenly over any area to clean it.
