Description

The present invention relates to an oil-based cleaning agent containing a higher fatty acid soap.

In order to wash off oily makeup cosmetics such as lipsticks, foundations, mascaras, and eye shadows, it is best to use an oily cleansing agent, and a liquid base is the best. Liquid oil-based cleansing agent, so-called cleansing oil, is widely used as a cleansing agent to remove make-up cosmetics because it has the advantage of being more familiar with make-up cosmetics than gel-like and cream-like bases. Will be done. Since cleansing oils are usually based on a large amount of oil and a small amount of nonionic surfactant, they are easily compatible with the oils contained in foundations and lipsticks, and have the characteristic that makeup cosmetics can be easily removed. ..

However, when the cleansing oil is washed away with water, the oil content remains on the skin, and the refreshing feeling is not sufficiently satisfactory, and further improvement of the refreshing feeling is desired. On the other hand, although higher fatty acid soap is very excellent in refreshing feeling after rinsing with water, it is insufficient in terms of familiarity with make-up and cleaning effect as compared with cleansing oil. In addition, such soaps usually do not dissolve in oils and cannot be mixed with cleansing oils in a uniform state.

In response to these conventional problems, it is required to develop an oil-based cleaning agent that has a high cleaning effect on makeup and can give a very refreshing feel after rinsing with water.

Japanese Unexamined Patent Publication No. 2014-152108

An object of the present invention is to provide an oil-based cleaning agent which has a high cleaning effect on makeup and gives a very refreshing feel after being washed away with water.

As a result of studies by the present inventor to solve the above problems, a predetermined amount of (A) isostearic acid and / or oleic acid is neutralized with (B) aminomethylpropanol and / or triethanolamine at a neutralization rate of 25 to 25 to The present invention is completed by finding that when neutralized at 150%, an oily soap is produced, which can be uniformly dissolved in (C) oil, and a very refreshing feel is obtained after rinsing with water. It came to.

That is, the present invention is an oil-based cleaning agent containing the following components (A), (B) and (C), wherein the amount of the component (A) is 1 to 7% by mass with respect to the component (A). It is an oil-based cleaning agent characterized by containing soap produced by neutralization by blending an amount of the component (B) corresponding to a neutralization rate of 25 to 150%.
(A) isostearic acid and / or oleic acid (B) aminomethylpropanol and / or triethanolamine (C) oil

Further, the present invention is a method for producing an oil-based cleaning agent containing the following components (A), (B) and (C), wherein the amount of the component (A) is 1 to 7% by mass, and the component (A) is blended. ), The component (B) in an amount corresponding to a neutralization rate of 25 to 150% is blended, and a soap produced by neutralization is contained, which is a method for producing an oil-based cleaning agent.
(A) isostearic acid and / or oleic acid (B) aminomethylpropanol and / or triethanolamine (C) oil

According to the oil-based cleaning agent of the present invention, the cleaning effect on makeup is high, and a very refreshing feel can be obtained after rinsing with water.

The oil-based cleaning agent of the present invention contains (A) isostearic acid and / or oleic acid, (B) aminomethylpropanol and / or triethanolamine, and (C) oil, and contains the component (A). The amount is 1 to 7% by mass, and the soap is neutralized and produced by blending the component (B) in an amount corresponding to a neutralization rate of 25 to 150% with respect to the component (A). To do.

The oil-based cleaning agent of the present invention contains a soap produced by neutralizing the fatty acid of the component (A) with the neutralizing agent of the component (B), so that it has a high cleaning effect and a refreshing feel after use. Can be obtained.

As the component (A), either isostearic acid or oleic acid may be used, or isostearic acid and oleic acid may be mixed and used.

The blending amount of the component (A) is 1 to 7% by mass with respect to the total amount of the oil-based cleaning agent. If the blending amount of the component (A) is less than 1% by mass, the feeling of refreshing after use is inferior. On the other hand, if it is blended in an amount exceeding 7% by mass, it does not dissolve in the component (C) and separates, so that it becomes difficult to obtain a uniform oil-based cleaning agent.

The component (B) used in the present invention is a neutralizing agent for neutralizing the above component (A). As the component (B), either aminomethylpropanol (AMP) or triethanolamine (TEA), or a mixture of aminomethylpropanol (AMP) and triethanolamine (TEA) can be used.

The component (B) is blended with the component (A) in an amount corresponding to a neutralization rate of 25 to 150%. If the amount of aminomethyl propanol (AMP) or triethanolamine (TEA) blended is less than the neutralization rate of 25% with respect to the component (A), the feeling of refreshing after use is inferior. On the other hand, if the neutralization rate exceeds 150%, the oil-based cleaning agent is separated and it becomes difficult to maintain a uniform state.

The neutralization rate refers to the molar ratio (percentage) of the total fatty acid salt after neutralization to the total fatty acids blended in the oil-based cleaning agent. In the present invention, the neutralization rate (%) is calculated by the following formula. can do.
Neutralization rate (%) = (number of moles of component (B)) / (number of moles of component (A)) x 100
That is, the component (B) may be blended in an amount corresponding to 25 to 150% of the number of moles of the component (A).

It is difficult to specify a plurality of components neutralized and generated by blending the component (B) in an amount corresponding to a neutralization rate of 25 to 150% with respect to the component (A). That is, there are circumstances (impossible / impractical circumstances) in which it is impossible or approximately impractical to directly identify the neutralized product by its structure or properties.

"Preparation of test product"
The test product was prepared by adding an antioxidant, a surfactant, a fatty acid, a neutralizing agent, water and a fragrance to the oil content, and stirring while heating.

"Evaluation test of cleaning effect"
In order to evaluate the cleaning effect on the make, an evaluation test of the cleaning effect was carried out according to the following procedure.
1) The reflectance of light on the surface of artificial leather is measured using a spectrophotometric color difference meter (manufactured by Nippon Denshoku Kogyo Co., Ltd.) (reflectance A value).
2) After applying foundation to the surface of artificial leather and drying for 3 hours, the reflectance of light is measured (reflectance B value).
3) Soak 0.5 ml of the test product in cotton (length 1 x width 3 cm), and make 5 reciprocations on the artificial leather while applying a load of 100 g to the cotton. The light reflectance of the artificial leather after wiping with a test product is measured (reflectance C value).
4) The cleaning effect was evaluated by the cleaning rate (%) calculated by the following formula.
Cleaning rate (%) = (CB) / (AB) x 100

"Evaluation of cleaning effect"
⊚: Cleaning rate is 90% or more (passed)
◯: Cleaning rate is 70% or more and less than 90% (pass)
Δ: Cleaning rate is 50% or more and less than 70% (failure)
X: Cleaning rate is less than 50% (failed)

"Method of sensory test"
In order to evaluate the refreshing feel after rinsing with water, a sensory test was performed according to the following procedure.
1) Apply 1g of the test product to the skin and let it blend into the face for 20 seconds.
2) Rinse your face with hot water at about 40 ° C for 60 seconds.

"Evaluation of sensory test"
The usability after rinsing the faces of 10 panelists was evaluated according to the following criteria, and the test products were evaluated with ⊚, ○, Δ, and × from the average score of 10 panelists.
<Evaluation of usability>
5: Very refreshing (feels crisp)
4: Refreshing (it feels a little squeaky)
3: Usually
2: Slimy 1: Very slimy <Evaluation of test product>
⊚: 4 or more and 5 or less (pass)
◯: 3 or more and less than 4 (pass)
Δ: 2 or more and less than 3 (failed)
×: 1 or more and less than 2 (failed)

"Condition observation and evaluation"
The state immediately after preparation and the state after standing at room temperature, 0 ° C., and 50 ° C. for 1 day were observed, and if there was no separation and a uniform state was maintained, it was evaluated as ○ (pass) and separation occurred. In the case, it was evaluated as × (failed).

Table 1 shows the evaluation results of the test products. Comparative Examples 1 and 2 in which no fatty acid was added were inferior in the sensory evaluation. Further, in Comparative Examples 5 to 9 containing lauric acid, the soap was separated immediately after the preparation of the test product, and a uniform oil-based cleaning agent could not be obtained. As the results of Examples 1 to 3 and Examples 4 to 6 show, good results can be obtained by blending isostearic acid and oleic acid as fatty acids, but the blending amount is 1 to 7 mass. If it is less than 1% by mass, the sensory evaluation is inferior as shown in Comparative Examples 3 and 10, and conversely, if it is more than 7% by mass, the soap becomes oily as in Comparative Examples 4 and 11. Separation occurred without dissolution.

From the results in Table 2, it is preferable to use aminomethylpropanol or triethanolamine as the neutralizing agent for neutralizing fatty acids (Examples 7 and 8). When potassium hydroxide is used, the soap produced as in Comparative Example 12 is in a separated state without being dissolved in the oil.

Table 3 shows the evaluation results when isostearic acid was neutralized with aminomethyl propanol or triethanolamine. Good results can be obtained by adjusting the amount of aminomethyl propanol to 25 to 150% of isostearic acid so that the neutralization rate is 25 to 150% (Examples 9, 10 to 13, 14 to 23 and 24). ), An amount less than 25% neutralization rate (Comparative Examples 17 and 18) and an amount more than 150% neutralization rate (Comparative Examples 13 to 16) are blended to obtain a separated state and a uniform oil-based cleaning agent. Can not. In addition, good results were confirmed in Examples 25 to 28 when triethanolamine was also used, but it was confirmed that the sensory evaluation was inferior when a small amount corresponding to a neutralization rate of 10% was added. (Comparative example 19).
