Description

[Detailed description of the invention]

(Industrial Field of Application) The present invention relates to a cosmetic containing coffee. (Prior Art) Cosmetics are often blended with fragrances in order to give a refreshing feeling when used.
Conventionally, most of these fragrances have been synthetic, and there are no known cosmetics that have a natural fragrance such as coffee. In addition, scrub cosmetics are cosmetics that have been attracting attention in recent years, and are cosmetics that contain various fine particles as scrubbing agents. The role of a scrub agent is to remove dead skin cells from the skin through friction, make the skin smooth, and thoroughly remove dirt from deep within the pores, keeping the skin clean.Furthermore, the friction activates the skin's metabolism, which improves the skin. Things like staying young. For this purpose, scrubbing agents conventionally used include mineral-based, e.g., marble particles, vegetable-based, e.g., crushed apricot seeds;
and synthetic resin-based particles such as polyethylene particles. (Problems to be Solved by the Invention) In addition to conventional synthetic fragrances, there is a strong demand for cosmetics that have new natural fragrances. Furthermore, among the above-mentioned scrubbing agents, natural product-based ones are too hard, giving a feeling of discomfort when used, while synthetic resin-based ones are too soft, making it difficult to obtain a sufficient scrubbing effect. There have been demands for scrub cosmetics. (Structure of the Invention) The cosmetic of the present invention is characterized by containing coffee. In one embodiment, the cosmetic composition of the present invention is characterized in that roasted coffee grains, preferably roasted at 250 to 300°C and ground, are blended as a scrubbing agent. As a result of examining the suitability of various materials as scrubbing agents, the present inventor found that coffee beans have an appropriate hardness, do not cause excessive irritation to the skin, and have an extremely good scrubbing effect. I found it. Because coffee is a food product, it can be safely incorporated into cosmetics, and it can give cosmetics a subtle scent unique to coffee.
It is the perfect material as a scrubbing agent. Furthermore, coffee contains pharmacological components such as tannins and caffein. Caffeine is expected to further enhance the pine surge effect of scrubs from a pharmacological perspective. Tannic acid is expected to have the effect of tightening the skin and making it easier to apply other cosmetics after washing the face with the cosmetics of the present invention. Furthermore, since coffee beans contain a large amount of oil and fat components, the cosmetics of the present invention can also be expected to give a firm feel to the skin. In order to incorporate coffee into cosmetics, it is first necessary to roast the coffee beans. Roasting not only gives the coffee grains a hardness suitable for use in exfoliants, but also creates a unique aroma. The roasting method may be generally the same as when roasting drinking coffee. Grinding after roasting is done by any method that can achieve a particle size suitable for exfoliating agents. The thus ground coffee is passed through a sieve, if necessary, to make the particle size suitable for use as a scrubbing agent. According to research conducted by the present inventors, it has been found that a particle size of 20 to 80 mesh, preferably about 60 mesh, provides a good scrubbing effect and does not cause excessive discomfort to the skin. When blending coffee particles into cosmetics, they may be blended as is, or the particles may be extracted with water or hot water, and the extracted components may be used in the production of powdered coffee or blended into cosmetics as coffee extract. If the remaining particles are incorporated into cosmetics as a scrubbing agent, coffee beans can be used effectively. According to the inventor's tests, the coffee particles after extraction were also sufficiently effective as a scrubbing agent. Since the coffee component is water-soluble, the scrubbing agent is preferably added to the oily component in the production of the cosmetic composition of the present invention, but otherwise the production of the cosmetic composition of the present invention can be carried out using conventional methods. You can go by this method. In another embodiment, the cosmetic of the present invention is characterized by containing coffee extract. Coffee extract, as described above, is obtained by extracting coffee particles with water or hot water. The amount of blending depends on the purpose, but in order to obtain a desirable fragrance, it is necessary to
At least 0.1 to 100 parts by weight of coffee grains
Add coffee extract equivalent to 1 part by weight. The upper limit of the blending amount is determined mainly from economical considerations. Cosmetics containing coffee extract in this way do not have a scrubbing effect, but in addition to providing a pleasant aroma, they are expected to have the effect of promoting blood circulation in the skin due to the caffeine and the tightening effect of the skin due to the tannic acid. The cosmetic of the present invention may contain a scrubbing agent and coffee extract at the same time. In any of the above embodiments, the cosmetic of the present invention may be any cosmetic that can contain a scrubbing agent or coffee extract, such as soap, cream (e.g., facial cleansing cream, pine surge cream, etc.), body cleanser, bath preparation, etc. . Below, the cosmetics of the present invention will be explained in more detail based on Examples and Test Examples. Example 1 Preparation of a scrubbing agent made of coffee particles Grinding of coffee beans The quality of coffee varies depending on its place of origin, variety, weather conditions, etc., but it also depends on the degree of roasting, grinding method, and blending. It is also possible to change the flavor and aroma through various processing steps such as. Therefore, in this embodiment, the following steps were taken. A. Origin and variety: Mainly Brazilian and Jiahua varieties, blended with bitter mocha. B Roast: Standard time is 15-20 minutes at about 250-300℃. C. Grinding: Hosobiki to medium, 20 to 20 mesh
It should be around 80. Extraction with hot water Add 70g to 50g of the above ground coffee to 1200g of hot water.
ml and filtered through filter cloth or filter paper. The filtrate was used as coffee extract, and the remaining particles were dried to obtain coffee scrub particles. Examples 2 and 3

[Table] Accurately weigh components 1, 2, 3, 4, 5, and 7, and heat to 80°C to dissolve (referred to as part A).
Meanwhile, weigh ingredients 6, 8 and 9 in another container, and
It was heated to ℃ (referred to as part B). Part B was added to Part A, stirred uniformly, and cooled to 40°C to obtain a coffee scrub facial cleansing foam. The product of Example 3 has slightly stronger face-washing properties. Examples 4 and 5

[Table] Each component was thoroughly mixed and molded using a press mold to obtain a soap. Example 6 Coffee pine surge cream Part A Stearic acid 7 Beeswax 2 Glyceryl monostearate 6 Squalane 10 Liquid paraffin 30 Propyl paraoxybenzoate 0.5 Part B Coffee extract 10 Methyl paraoxybenzoate 0.5 Glycerin 5 Purified water 29 Accurately determine the ingredients of Part A Weigh and dissolve by heating. Meanwhile, weigh out the components of part B in a separate container and dissolve at a temperature of about 80°C. Add part B to part A, stir well, and cool to below 40°C while stirring to make coffee pine surge cream. In this example, the coffee scrub is about 3%
In addition, the amount of purified water can be reduced by about 3%. Tannic acid in coffee has a skin tightening effect. Test Example 1 A usage test was conducted using the coffee scrub facial cleansing foam produced in Example 2. In this test, 7 women (5 in their 20s, 1 in their 30s, 1 in their 50s)
The respondents were asked to give their impressions after using the product in three categories: good, somewhat good, and unknown effect, and the results were evaluated as shown in Table 1.

[Table] As is clear from the above results, the cosmetic composition of the present invention was highly evaluated for its scrubbing effect, and was recognized to have sufficient usefulness in the overall evaluation. (Effects of the Invention) As explained above, the coffee-containing cosmetic of the present invention has the advantage that the scrubbing agent is coffee particles with appropriate hardness, so it has a high scrubbing effect and does not irritate the skin excessively. . moreover,
The faint coffee scent when used is very desirable as a cosmetic. The present invention can be applied to various cosmetics other than those described in the Examples.
