Description

Oily cleaning product

Technical Field

The present invention relates to an oily cleansing product containing a higher fatty acid soap.

Background

In order to wash off an oil-containing cosmetic makeup such as lipstick, foundation, mascara, eye shadow, etc., a cleansing product containing a large amount of oil is used, and since the cleansing effect is the highest and the liquid base has an advantage that the affinity with the cosmetic makeup is better than other gel-like or cream-like bases, a liquid oil cleansing product, so-called makeup remover, is widely used as a cleansing product for dropping off the cosmetic makeup. The makeup remover oil is generally based on a large amount of oil and a small amount of nonionic surfactant, and therefore, has a characteristic that it easily adheres to oil blended with foundation, lipstick, or the like, and can easily drop a makeup color.

However, when cleansing oil is washed with water, the oil remains on the skin and is not sufficiently satisfactory in terms of refreshing feeling, and further improvement of refreshing feeling is desired. On the other hand, higher fatty acid soaps have a very excellent refreshing feel after being washed with water, but are insufficient in affinity for cosmetics and cleansing effect as compared with makeup remover oils. In addition, such soap is generally insoluble in oil and cannot be blended in makeup remover oil in a uniform state.

In order to solve such conventional problems, there has been a demand for development of an oil-based cleansing article which has a high cleansing effect on cosmetics and can provide a very refreshing feeling after rinsing with water.

ADVANTAGEOUS EFFECTS OF INVENTION

The oily cleansing product of the present invention has a high cleansing effect on a cosmetic, and can give a very refreshing feeling after rinsing with water.

Detailed Description

The oil-based cleaning product is characterized by containing (A) isostearic acid and/or oleic acid, (B) aminomethylpropanol and/or triethanolamine, and (C) an oil component, and by containing a soap produced by neutralizing the component (A) in an amount of 1 to 7% by mass and the component (B) in an amount corresponding to a neutralization rate of 25 to 150% with respect to the component (A).

The oil-based cleansing product of the present invention contains a soap produced by neutralizing a fatty acid based on component (a) with a neutralizing agent based on component (B), and can provide a high cleansing effect and a refreshing feeling after use.

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 amount of the component (A) is 1 to 7% by mass based on the total amount of the oily cleansing product. When the amount of component (a) is less than 1% by mass, the feeling after use is poor. On the other hand, when the amount exceeds 7% by mass, the component (C) is not dissolved and separated, and therefore it is difficult to obtain a uniform oily cleaning product.

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) may be used, or Aminomethylpropanol (AMP) and Triethanolamine (TEA) may be mixed and used.

The component (B) is blended in an amount corresponding to a neutralization rate of 25 to 150% with respect to the component (A). When the amount of aminomethyl propanol (AMP) or Triethanolamine (TEA) is less than 25% of the neutralization rate of component (a), the feeling after use is poor. On the other hand, if the amount is more than 150% of the neutralization rate, separation occurs in the oil-based cleansing product, and it is difficult to maintain a uniform state.

The neutralization rate is a molar ratio (percentage) of the total fatty acid salts after neutralization to the total fatty acids blended in the oily cleansing agent, and in the present invention, the neutralization rate (%) can be calculated from the following calculation formula.

Neutralization ratio (%) ((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 mol% of the mol of the component (a).

It is difficult to specify a plurality of components produced by neutralizing the component (A) with the component (B) in an amount corresponding to a neutralization rate of 25 to 150%. That is, there are cases where it is impossible to directly specify a neutralized product according to the structure or characteristics thereof, or where it is not practical at all (cases where it is impossible or impractical).

Examples

The present invention will be described in further detail below with reference to examples, but the present invention is not limited to these examples. The numerical values in the table represent% by mass unless otherwise specified.

Preparation of test article "

The test articles were adjusted as follows: adding antioxidant, surfactant, fatty acid, neutralizer, water and perfume into the oil component, and heating while stirring for adjustment.

Evaluation test of cleaning Effect "

In order to evaluate the cleansing effect on the cosmetic, a cleansing effect evaluation test was performed according to the following procedure.

1) The reflectance (reflectance a value) of light on the surface of the artificial leather was measured by a spectroscopic color difference meter (manufactured by nippon electrochromic industries).

2) After applying a foundation on the surface of the artificial leather and drying it for 3 hours, the reflectance of light (reflectance B value) was measured.

3) 0.5ml of a test piece was contained in cotton (1X 3cm in length) and the test piece was reciprocated 5 times on the artificial leather while applying a load of 100g to the cotton. The light reflectance (reflectance C value) of the artificial leather after being rubbed off on the test piece was measured.

4) The cleaning effect was evaluated from the cleaning rate (%) calculated from the following formula.

Washing rate (%) - (C-B)/(a-B) × 100

Evaluation of cleaning Effect "

◎ cleaning rate is more than 90% (qualified)

○ the cleaning rate is above 70% and below 90% (qualified)

△ cleaning rate is more than 50% and less than 70% (unqualified)

X: cleaning rate lower than 50% (unqualified)

Method of functionality test "

In order to evaluate the refreshing feeling after rinsing with water, a sensory test was performed according to the following procedure.

1) The test article 1g was applied to the skin and allowed to face for 20 seconds.

2) The face was rinsed with hot water at about 40 c for 60 seconds.

Evaluation of the functionality test "

The feeling of use after washing the face was given to 10 panelists by the following criteria, and the test pieces were evaluated by averaging the 10 panelists using ◎, ○, △ and x.

< evaluation of feeling of use >

5: very fresh and cool (become a sense of smoothness)

4: refreshing (becoming a slightly slippery touch)

3: general purpose

2: stick-slip

1: very stick-slip

< evaluation of test article >

◎ ratio of 4 to 5 inclusive (acceptable)

○ ratio of more than 3 and less than 4 (acceptable)

△ ratio 2 or more and less than 3 (fail)

X: 1 or more and less than 2 (unqualified)

"evaluation of State Observation"

The state immediately after the preparation and the state after the standing at room temperature, 0 ℃ and 50 ℃ for 1 day were observed, and the case where the separation was not caused and the uniform state was maintained was evaluated as ○ (pass), and the case where the separation was caused was evaluated as x (fail).

[ Table 1]

The evaluation results of the test pieces are shown in table 1. In comparative examples 1 and 2 in which no fatty acid was added, the results of the sensory evaluation were poor. In comparative examples 5 to 9 in which lauric acid was added, the soap separated from the test product immediately after the preparation, and a uniform oily cleansing product could not be obtained. As shown by the results of examples 1 to 3 and 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% by mass, and if less than 1% by mass, the functional evaluation is poor as shown in comparative examples 3 and 10, whereas if more than 7% by mass is blended, the soap is not dissolved in the oil and is separated as shown in comparative examples 4 and 11.

[ Table 2]

From the results of table 2, as the neutralizing agent for neutralizing the fatty acid, aminomethylpropanol or triethanolamine (examples 7, 8) is preferably used. When potassium hydroxide was used, the soap produced was separated without dissolving in the oil as in comparative example 12.

[ Table 3]

Table 3 shows the evaluation results of the neutralization of isostearic acid with aminomethyl propanol or triethanolamine. Good results were obtained by blending aminomethylpropanol with isostearic acid in an amount such that the neutralization rate was 25 to 150% (examples 9, 10 to 13, 14 to 23 and 24), but if the amount was less than 25% of the neutralization rate (comparative examples 17 and 18) and greater than 150% of the neutralization rate (comparative examples 13 to 16), the product was separated and a uniform oily cleaning product could not be obtained. In addition, in the case of using triethanolamine, good results were confirmed in examples 25 to 28, but in the case of adding a small amount corresponding to a neutralization rate of 10%, it was confirmed that the functional evaluation was poor (comparative example 19).
