Abstract

PURPOSE:To provide a cleansing cosmetic containing limonene, having excellent cleaning effect, giving extremely refreshing and pleasant feeling to the skin, and useful as cream, milky lotion, etc. CONSTITUTION:The objective cosmetic contains limonene which is a colorless transparent liquid having a boiling point of 88-94 deg.C (under 50mmHg) and obtained from the fruit peel or leaf of citrus such as trangerine, lemon, etc. It has high solubility of fat and fatty acid, etc. and high volatility (which gives extremely refreshing feeling to the skin). The content of limonene in the cosmetic is 2-40%. Limonene is used in the form of cream or milky lotion, etc., by emulsifying the compound and optionally other oil and fat with a surfactant by conventional method.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cleansing cosmetic product that has an enhanced cleaning effect and a significantly improved feel after use.

(Prior art) Conventionally, cleansing creams or cleansing emulsions, etc. contain liquid paraffin of 30 to 40 parts and surfactants of 8 to 1 part.
0%, other antioxidants, fragrances, preservatives, etc.
It is made using liquid paraffin as the main ingredient. However, many people are dissatisfied with it because it has a weak dirt cleaning effect.

(Problems that @Ming tries to solve) As mentioned above, conventional cleansing creams and cleansing emulsions have weak cleaning effects, so there has been a desire for cleansing cosmetics that have a sufficiently satisfactory cleaning effect.

(Means for Solving the Problems) As a result of intensive research in order to solve the above problems, the present inventor found that by incorporating limonene into a cream or milky lotion, the cleaning effect is enhanced between the nails. , and the feel after use is significantly improved, leading to the completion of the present invention. That is, the present invention is a cleansing cosmetic product characterized by containing limonene.

Limonene used in the present invention is obtained from the peel or leaves of citrus fruits such as mandarin oranges and lemons, and has a boiling point of 88 to 94C (
It is a colorless and transparent liquid with a weight of 50 Hg) and has a mandarin flavor.

In the present invention, creams and emulsions containing limonene can be easily prepared by a conventional method of emulsifying limonene alone or together with other oils and fats using a surfactant. In addition, the cleansing cosmetics according to the present invention include:
It is not limited to the above-mentioned cream or milky lotion, and can be prepared in any suitable form.

The results of testing the effects of the limonene-containing cleansing cosmetics of the present invention are as follows.

Test 1 Changes in the amount of stearic acid dissolved in liquid paraffin and limonene-containing liquid paraffin (temperature 50C) The test results are shown in the drawing.

Test 2 Lard solubility test conditions for liquid paraffin and liquid paraffin containing limonene Temperature 20C Lard 10 in liquid paraffin 302? When mixed, it becomes cloudy. When this liquid was stirred and limonene was gradually added, the turbidity gradually became thinner, and when limonene 147 was added, the liquid became clear. liquid paraffin 501
Even when liquid paraffin 207 was added to a mixture of lard and lard, the turbid state hardly changed.

As is clear from the above test, limonene has the following properties:
Because the fatty acids are highly soluble and volatile, it gives a very light feeling after use. Regarding the effect of limonene on the skin, a circular patch test with a diameter of 3 points was performed on the inside of the upper part of the left arm of 16 people for 6 hours using the cream prepared in Example 6, and all of them were negative. Therefore, it is considered to be highly safe for the skin.

However, since limonene is volatile, its vapor irritates the eyes like alcohol etc., so the content of limonene is suitably 40% or less. However, the results of Test 1 show that there is no effect if the amount of limonene is small, at least 2%.
The above additions are necessary.

(Effect of @Ming) As is clear from the above test results, the limonene-containing cleansing cosmetic of the present invention has an excellent cleaning effect and feels extremely good after use.
