Description

Oily cleaning material

The present invention relates to an oily cleaning material containing a higher fatty acid soap.

In order to wash off lipsticks, powders, mascara, eye shadows and other oil-containing makeup cosmetics, the use of detergents containing more oils has the highest cleaning effect. In addition, liquid bases and other gels and creams Compared with creamy base, it has the advantage of better affinity with makeup cosmetics. Therefore, the so-called cleansing oil in liquid form is widely used as a cleaning material for removing makeup cosmetics. Cleansing oils have the following characteristics: usually a large amount of oil and a small amount of non-ionic surfactants are used as a base, so it is easy to be compatible with oils mixed with powder or lipstick, and can easily remove makeup cosmetics.

However, if the cleansing oil is rinsed with water, the oil content remains on the skin, which is not sufficiently satisfactory in terms of refreshing feeling, and further improvement in the refreshing touch is expected. On the other hand, although the higher fatty acid soap is excellent in refreshing feeling after rinsing with water, it is inadequate in terms of its affinity for makeup and washing effect compared with cleansing oil. In addition, such soaps are generally insoluble in oil and cannot be blended with cleansing oils in a uniform state.

In response to such a problem since the learning, it is required to develop an oily cleaning material which has a high washing effect on makeup and can obtain a very refreshing touch after rinsing with water.

[Problems to be Solved by the Invention]

The object of the present invention is to provide an oily cleaning material which has a high cleaning effect on makeup and can obtain a very refreshing touch after rinsing with water. [Technical means to solve the problem]

In order to solve the above problems, the present inventors conducted research and found that if (B) aminomethylpropanol and / or triethanolamine were used to neutralize a specific amount of (A) isostearic acid at a neutralization rate of 25 to 150% And / or oleic acid, an oily soap is formed, which can be uniformly dissolved in the (C) oil component, and a very refreshing touch can be obtained after rinsing with water, thereby completing the present invention.

That is, the present invention is an oily cleaning material which is blended with the following components (A), (B), and (C), and is characterized by containing soap, which is obtained by setting the blending amount of the component (A) It is 1 to 7% by mass, and the component (B) is blended in an amount equivalent to a neutralization rate of 25 to 150% to the component (A) to be neutralized. (A) Isostearic acid and / or oleic acid (B) Aminomethylpropanol and / or triethanolamine (C) Oil content

In addition, the present invention relates to a method for producing an oily cleaning material, which is a method for producing an oily cleaning material containing the following components (A), (B), and (C), which is characterized in that it contains soap. The blending amount of the component (A) is 1 to 7 mass%, and the component (B) corresponding to a neutralization rate of 25 to 150% is blended with the component (A) to be neutralized. (A) Isostearic acid and / or oleic acid (B) Aminomethylpropanol and / or triethanolamine (C) Oil content [Effect of the invention]

According to the oily cleaning material of the present invention, the washing effect on makeup is high, and a very refreshing touch can be obtained after rinsing with water.

The oily cleansing material of the present invention is characterized in that (A) isostearic acid and / or oleic acid, (B) aminomethylpropanol and / or triethanolamine, and (C) an oil component are mixed, and contains soap, The soap is neutralized by blending the component (A) in an amount of 1 to 7% by mass and blending the component (B) in an amount equivalent to a neutralization rate of 25 to 150% with respect to the component (A). generate.

The oily cleaning material of the present invention contains a soap produced by neutralizing the fatty acid based on the component (A) with a neutralizing agent based on the component (B), and can obtain a high cleaning effect and refreshing after use. Touch.

As 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 mass% based on the total amount of the oily cleaning material. If the blending amount of the component (A) is less than 1% by mass, the refreshing touch after use is poor. On the other hand, if it is blended in excess of 7% by mass, it will be separated without dissolving in the component (C), and it will be difficult to obtain a uniform oily detergent.

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

The component (B) is an amount equivalent to a neutralization rate of 25 to 150% based on the blending of the component (A). If the blending amount of aminomethylpropanol (AMP) or triethanolamine (TEA) is an amount lower than the neutralization rate of the component (A) by 25%, the refreshing feeling after use is poor. On the other hand, if it exceeds 150% of a neutralization rate, an oily washing | cleaning material will isolate | separate, and it will become difficult to maintain a uniform state.

The neutralization rate refers to the molar ratio (percentage) of all fatty acid salts after neutralization to all fatty acids blended in the oily detergent. In the present invention, the neutralization rate (%) can be calculated according to the following formula Figure it out. Neutralization rate (%) = (Mole number of component (B)) / (Mole number of component (A)) × 100 That is, as long as the component (B) is blended, it is equivalent to the mole number of the component (A). An amount of 25 to 150% of the mole number is sufficient.

Furthermore, it is difficult to specify a plurality of components neutralized by blending the component (B) in an amount equivalent to 25 to 150% with respect to the component (A). That is, the neutralization product cannot be directly specified by its structure or characteristics, or there are completely unrealistic situations (impossible and impractical situations).

"Preparation of test product" The test product was adjusted by adding antioxidants, surfactants, fatty acids, neutralizers, water, and fragrances to the oil while stirring.

"Evaluation test of cleaning effect" In order to evaluate the cleaning effect on makeup, an evaluation test of the cleaning effect was performed in the following order. 1) Use a spectrophotometer (manufactured by Nippon Denshoku Industries Co., Ltd.) to measure the light reflectance (reflectance A value) on the surface of artificial leather. 2) Apply the powder on the surface of artificial leather, and after drying for 3 hours, measure the light reflectance (reflectance B value). 3) 0.5 ml of the test article is contained in cotton (warp 1 × weft 3 cm), and a 100 g load is applied to the cotton while reciprocating 5 times on the artificial leather. The light reflectance (reflectivity C value) of the artificial leather after being wiped with the test article was measured. 4) The washing effect was evaluated by the washing ratio (%) calculated from the following formula. Washing rate (%) = (C-B) / (A-B) × 100

"Evaluation of cleaning effect" ◎: The cleaning rate is 90% or more (pass) ○: The cleaning rate is 70% or more and less than 90% (pass) △: The cleaning rate is 50% or more and less than 70% (Failure) ×: The cleaning rate is less than 50% (Failure)

"Method of functional test" In order to evaluate the refreshing feeling after rinsing with water, the functional test was performed in the following order. 1) Apply 1 g of the test article to the skin, and fuse to the face for 20 seconds. 2) Wash your face with hot water at about 40 ° C for 60 seconds.

"Evaluation of Sensory Test" The test scores of 10 sensory inspectors were evaluated based on the following criteria based on the average score of 10 sensory inspectors, and the test samples were evaluated by ◎, ○, △, and ×. ＜ Evaluation of usability ＞ 5: Very refreshing (smooth touch) 4: Refreshing (smooth touch) 3: Normal 2: Sticky 1: Very sticky <Evaluation of test product> ◎: 4 or more and 5 or less (pass) ○: 3 or more and less than 4 (pass) △: 2 or more and less than 3 (fail) ×: 1 or more and less than 2 (fail)

"Status observation and evaluation" The state immediately after preparation was observed, and the state after standing at room temperature, 0 ° C, and 50 ° C for 1 day was observed. When the state was kept uniform without separation, the evaluation was ○ (passed) ), When separation occurs, it is evaluated as × (failed).

[Table 1]

Table 1 shows the evaluation results of the test samples. Comparative Examples 1 and 2 in which no fatty acid was blended were inferior in functional evaluation. Further, in Comparative Examples 5 to 9 in which lauric acid was blended, the soap was separated immediately after the test product was prepared, and a uniform oily detergent was not obtained. As shown in the results of Examples 1 to 3 and Examples 4 to 6, good results can be obtained by blending isostearic acid and oleic acid as fatty acids, but the blending amount is preferably 1 to 7 Mass%. If it is less than 1% by mass, as shown in Comparative Examples 3 and 10, the sensory evaluation is poor. On the other hand, if it is more than 7% by mass, soap is not dissolved in oil as in Comparative Examples 4 and 11. Separation.

[Table 2]

Based on the results in Table 2, it is preferable to use aminomethylpropanol or triethanolamine as a neutralizing fatty acid neutralizer (Examples 7 and 8). When potassium hydroxide is used, the soap produced as in Comparative Example 12 is in a state where it is not dissolved in oil and is separated.

[table 3]

Table 3 shows the evaluation results when neutralizing isostearic acid with aminomethylpropanol or triethanolamine. Good results can be obtained by setting the amount of aminomethylpropanol such that the neutralization rate to isostearic acid is 25 to 150% (Examples 9, 10 to 13, 14 to 23, and 24), However, if the amount is less than 25% (Comparative Examples 17, 18) or more than 150% (Comparative Examples 13 to 16), it will be in a separated state and a uniform oily wash cannot be obtained. Net material. In the case of using triethanolamine, good results were also confirmed in Examples 25 to 28. However, when a small amount equivalent to a neutralization rate of 10% was blended, it was confirmed that the functional evaluation was poor ( Comparative Example 19).
