Description

Soluble skin cleanser composition

The present invention relates to a composition for a soothing skin cleanser.

It is known that solid oil and fat components contained in makeup dirt that are difficult to remove, such as waterproof mascara, are removed by dissolving with oil. Therefore, makeup removers that use oils as cleaning ingredients have been marketed in various formulations such as creams, gels, and liquids (liquid).

These preparations are usually made by appropriately combining nonionic surfactants in order to flush away the oil from which the dirt has been dissolved. However, there is a problem that the preparation of the combination of the oil agent and the nonionic surfactant alone is not refreshing due to the greasyness during washing or the remaining oil agent after washing. Therefore, many consumers are further washed by washing materials such as pigments after removing makeup.

For example, Patent Document 1 describes a makeup remover composition containing a nonionic surfactant with a specific HLB, a low viscosity oil, and a water-soluble solvent, which has excellent makeup cleansing power and can be washed out cleanly. However, although this makeup remover composition can be flushed out without being greasy, it cannot cause a refreshing feeling of skin that is thoroughly washed as if the skin was washed by washing the pigment.

In addition, a review is made of a makeup remover composition in which an anionic surfactant is combined with a nonionic surfactant, an oil agent, and a polyol (Patent Documents 2 and 3), where the role of the anionic surfactant is to improve the composition The rinsability of the product, but it still can't cause the skin to be washed thoroughly like a face wash.

In addition, Patent Document 4 describes a makeup remover composition that imparts a refreshing feeling by combining an anionic surfactant, a polysiloxane-based nonionic surfactant, and a polysiloxane oil. However, when co-existing anionic surfactants and nonionic surfactants, from the viewpoint of long-term stability, the choice of surfactants is relatively large, and it is not possible to obtain sufficient stability while maintaining A composition that feels thoroughly washed like a face wash.

The present invention relates to a soluble skin cleanser composition, which contains the following components (A), (B), (C), (D), (E) and (F): (A) HLB 6-18 Non-ionic surfactant 7~30% by mass; (B) Fatty acid salt content based on fatty acid conversion 0.1~4% by mass; (C) Oil agent 5~20% by mass; (D) Water-soluble solvent 10~60% by mass %; (E) selected from ginseng (hydroxymethyl)aminomethane, aminomethylpropanol, aminomethylpropanediol, spermine, lysine, histidine, tryptophan and ornithine Alkali 0.1~6% by mass; (F) water 5~40% by mass; content ratio of component (B) relative to component (A) (B)/(A) is 0.06~0.35.

The present invention is solubilized by combining an oil agent with a nonionic surfactant having a moderate HLB and an appropriate amount of a fatty acid salt, and exerts the detergency of the oil agent when applied to the skin, and can be used to waterproof mascara Dissolve makeup that is difficult to remove. In addition, the purpose is to obtain a feeling of thoroughly cleansing the skin caused by the formation of fatty acid salt scum after being washed away quickly without being greasy at the time of flushing, which can actually be felt by A detergent composition that cleans the skin like washing the paint.

In addition, when a nonionic surfactant and a fatty acid salt are combined, the pH becomes alkaline, so the fatty acid is generated by hydrolysis of the nonionic surfactant during long-term storage, and the fatty acid becomes trapped in a state where neutralization is reduced. At the same time, it also solves the problem of precipitation at low temperatures.

The inventors of the present invention discovered that by containing specific nonionic surfactants, fatty acid salts, oils, water-soluble solvents, specific alkalis and water, and using specific nonionic surfactants and fatty acids in combination at specific ratios Salt, which can obtain long-term storage stability, high washing power, and can be rinsed quickly without being greasy when washed out, and a soluble skin cleanser composition that gives a refreshing touch to the washed skin.

The soluble skin cleanser composition of the present invention has a high cleaning power, and at the same time, it is not greasy and can be quickly rinsed off at the same time. The storage stability is also superior. Also, the sense of irritation to the eyes has been improved.

In the present invention, the solubilization refers to a liquid phase in which the thermodynamic properties of the oil agent and the water phase component are mutually dissolved due to the surfactant, which shows a transparent to translucent appearance.

In the soluble skin cleansing agent composition of the present invention, a nonionic surfactant and an anionic surfactant are mainly used together to form a soluble system, but due to the HL (hydrophilicity-hydrophobicity) of the nonionic surfactant The equilibrium changes with temperature, so the cloud point appears in the soluble composition at high temperature, and the solubility limit point appears on the low temperature side. The area between this cloud point and the soluble limit point is called the soluble temperature area. The expansion of this temperature area will cause the expansion of the stable temperature area of the generated soluble composition, while increasing the amount of oil soluble .

As a solubilized product, it is important that the appearance does not change in the actual use temperature range. In order to withstand actual life use, it is preferable to maintain the solubilized state in the temperature range of 0°C to 40°C.

These bases are not in the form of salts (there is no need to form fatty acid salt salts with fatty acid-like acidic components), but are formulated to exist in the composition in a free form.

Since the soluble skin cleansing composition of the present invention contains fatty acid salts, the pH becomes alkaline. However, under long-term storage under the coexistence of water, hydrolysis of nonionic surfactants is likely to occur, generating free fatty acids, and the pH of the system gradually decreases. The change also affects the degree of neutralization of fatty acids, and unneutralized fatty acids are easily precipitated at low temperatures. In the present invention, since the component (E) is further co-existed in the solubilized skin cleanser composition, the free fatty acid generated during long-term storage under the coexistence of water is neutralized to promote re-dissolution.

Furthermore, in the fatty acid salt of component (B), the salt containing (b2) is selected from the group consisting of ginseng (hydroxymethyl)aminomethane, aminomethylpropanol, aminomethylpropanediol, spermine acid, and amine.

Step 5: Add ingredients 19-22, ingredient 26, ingredient 28 to the preparation of step 4, and mix uniformly at 200 rpm to obtain a soluble skin cleanser composition.

(Evaluation method) (1) Appearance immediately after manufacturing:

Immediately after manufacturing, 40 mL of each skin cleanser composition was added to a 50 mL sample bottle (made by Tokyo Glass Equipment Co., Ltd.: Specification Bottle #6), and visually observed, it was evaluated as transparent, translucent, cloudy, separated, and precipitated Which.

At this time, the transparent, translucent, and white turbidity are arranged on the side of the sample bottle with a black plate printed with a bar and a bar code with a width of 0.4~1.0mm and a square size number of 2.0mm, from the opposite side When visually observing, it is judged as follows based on the recognition of barcode and numbers.

"Transparent" is set to a state where the lines and numbers of the barcode can be clearly recognized.

"Translucent" is set to a state where the line of the barcode can be recognized, but the number cannot be recognized.

"White turbidity" is set to a state where the lines and numbers of the barcode cannot be recognized.

In addition, those who observed phase separation or precipitation of contents in each skin cleansing composition were identified as separation and precipitation, respectively.

(2) pH immediately after manufacturing

Immediately after production, the stock solution of each skin cleanser composition was measured with a pH meter (Horiba Manufacturing Co., Ltd.: desktop pH‧water quality analyzer LAQUAF-72T) at 30°C. At this time, the measurement was performed by gently stirring for 15 minutes until the value stabilized, and the stable value after stirring was measured.

(3) Temperature stability immediately after manufacture (solvent temperature range): (3-1) Determination of fog point:

Put 30mL of each skin cleanser composition and stirrer in a 50mL sample bottle (manufactured by Tokyo Glass Instruments Co., Ltd.: Specification Bottle #6), and warm up with a 70°C water bath until white turbidity occurs. Thereafter, it was taken out from the water bath. Under the environment of 25° C., the sample bottle was cooled on a stirrer while stirring the stir bar at 350 rpm. Here, the temperature that becomes transparent to translucent is used as the fog point.

(3-2) Determination of soluble limit point:

Put 40mL of each skin cleanser composition in a 50mL sample bottle (manufactured by Tokyo Glass Instruments Co., Ltd.: Specification Bottle #6), and store in a constant temperature bath at 5°C, 0°C, and -5°C for 12 hours. Thereafter, by visually observing the appearance at each temperature, it was evaluated as transparent, translucent, cloudy, two-layer separated, and precipitated. The lowest value of the temperature that can maintain the transparent to translucent appearance is taken as the solubility limit point.

(4) Solubility of oily mascara:

On a glass plate (MICRO SLIDE GLASS, manufactured by Matsunami Co., Ltd.), uniformly apply 3 g of waterproof mascara (Maybelline, Magnum Volum Mascara waterproof type) in a circular shape with a diameter of 12 mm. After drying for 8 hours, 0.03 g of each skin cleansing composition was dropped, and it was melted at a rate of 1 circle per second with a fingertip pressure of about 100 g. After 50 cycles of fusion, the dissolution and residual degree of the mascara were observed and evaluated according to the following criteria.

(Judgment criteria)

5: The mascara is completely dissolved (no mascara remains on the glass plate).

4: The mascara is almost dissolved (less than 10% mascara remains on the glass plate).

3: The mascara is semi-dissolved (more than 10% to 50% of the mascara remains on the glass plate).

2: A small amount of mascara dissolves (more than 50% to 90% mascara remains on the glass plate).

1: The mascara is almost undissolved (more than 90% of the mascara remains on the glass plate).

(5) Flushing speed

There are 5 professional judges who actually use each skin cleanser composition on the face and rinse the reagent. As an evaluation index, a washing pigment (Biore Skin Care washing pigment manufactured by Kao Corporation) was used, and the washing speed was evaluated based on the number of people who were evaluated as non-greasy when washing each skin cleanser composition as non-greasy.

(Evaluation criteria)

5: 5 out of 5 persons were evaluated as rapid flushing.

4: 4 out of 5 persons were evaluated as rapid flushing.

3: 3 out of 5 persons were evaluated as rapid rinsing.

2: Two out of five people evaluated that the flushing was fast.

1: 1 out of 5 people rated as rapid flushing.

(6) Naked muscle feeling just after washing

There are 5 professional judges who actually use each skin cleanser composition on the face and rinse the reagent. As an evaluation index, wash pigments (made by Kao Corporation, Biore Skin Care wash pigments) are used, and the skin feels completely washed after washing (the skin before being wiped with a towel is still wet). ) The evaluation is the same number of people as the washing pigment, and the naked muscle feeling immediately after washing is evaluated.

(Evaluation criteria)

5: 5 out of 5 people were evaluated as feeling naked.

4: 4 out of 5 persons were evaluated as feeling naked.

3: Three out of five persons were evaluated as feeling naked.

2: Two out of five were evaluated as feeling naked.

1: One or less of five people were evaluated as feeling naked.

(7) Temperature stability after long-term storage (solvent temperature range)

Evaluate the temperature stability after long-term storage. Specifically, in order to accelerate the deterioration, 180 mL of each skin cleanser composition was filled in a PET container (manufactured by Yoshino Industries: AL-CL06A case 200M NB527C Oil), and stored at 50°C for one month, following the above ( 3-1) Determine the fog point in the same way. In addition, about the solubility limit point, after accelerated degradation in the same manner, the solubility limit point was measured in the same manner as in (3-2) above.

(8) The degree of pain when entering the eyes

Three professional judges, assuming the removal of mascara, blended each skin cleanser composition around the eyelashes and around the eyes for 20 seconds, opened the eyes and blinked 10 times, when the composition entered the eyes The degree of pain. Set 4 points for almost no pain, 3 points for extremely weak pain, 2 points for slightly weak pain, and 1 point for weak pain. The degree of pain. In addition, when using washing pigments (made by Kao Corporation, Biore Skin Care washing pigments), I felt very strong pain.
