Description

[Detailed description of the invention] (Industrial application field) The present invention relates to cosmetics containing coffee.

(Prior Art) Cosmetics are often blended with fragrances in order to give a refreshing feeling when used.

Conventionally, most of these strong 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 by friction, make the skin smooth, and thoroughly remove dirt from deep within the pores to keep the skin clean, and also to prevent skin renewal due to friction. , keeping the skin youthful, etc. For this purpose, scrubbing agents conventionally used include mineral based agents such as marble particles, vegetable based agents such as ground apricot seeds, and synthetic resin based agents such as polyethylene particles.

(Problems to be Solved by the Invention) There is a strong demand for cosmetics that have new scents based on natural products in addition to conventional synthetic scents.

Furthermore, among the above-mentioned scrubbing agents, natural product-based ones are too hard and give a feeling of discomfort when used, while synthetic resin-based ones are too soft and do not provide a sufficient scrubbing effect. There have been demands for scrub cosmetics.

(Structure of the Invention) The cosmetic of the present invention is formulated with coffee.

In one embodiment, the cosmetic composition of the present invention is characterized in that it contains roasted and ground coffee grains as a scrubbing agent.

As a result of examining the suitability of coffee beans as a scrubbing agent, 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 out. Since coffee is a food product, it can be safely incorporated into cosmetics, and it can give cosmetics a subtle scent unique to coffee, making it an ideal material for scrubbing agents. Furthermore, coffee contains pharmacological components such as tannins and caffeine.

Caffeine is expected to further enhance the pine surge effect of scrubs. 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 silky feel to the skin.

In order to incorporate coffee into cosmetics, it is first necessary to roast the coffee beans. Roasting does not cause the coffee grains to have a consistency suitable for exfoliants, but also develops a distinctive 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 the particle size suitable for a scrubbing agent.The coffee thus ground is passed through a sieve as necessary to make the particle size suitable for a scrubbing agent. According to the research conducted by the present inventors, it has been found that a particle size of eO~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. By incorporating the remaining particles into cosmetics as a scrubbing agent, it is possible to effectively utilize coffee beans. 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-bathable, the scrubbing agent is preferably added to the oil-based 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 do it using 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, at least an amount equivalent to 0.1 to IVIT coffee grains is blended to 100 it parts of the cosmetic.

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 can be expected to have the effect of promoting blood circulation in the skin due to the caffeine, and the effect of tightening 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 containing a scrubbing agent or coffee extract, such as soap, cream (e.g., facial cleansing cream, massage cream, etc.), body cleanser-1 bath preparation, etc. It's fine.

The cosmetic composition of the present invention will be explained in more detail below using Examples and Test Examples.

Example 1 Preparation of a scrubbing agent made from coffee particles ■ The quality of ground coffee beans varies depending on the region of origin, variety, weather conditions, etc., but it also depends on the degree of roasting, grinding method, It is also possible to change the flavor and aroma through divine processing processes such as blending. Therefore, in this embodiment, the following steps were taken.

A. Origin and variety: Mainly Brazilian and Java varieties, blended with bitter mocha.

B Roast: 15-20 at about 250-300'C
Minutes are standard.

C. Grinding: Fine to medium grinding, with a mesh size of about 20 to 80.

■ Extraction with hot water Add 70g to 50g of the above ground coffee to 1200g of hot water.
m/ and filtered through filter cloth or filter paper. Rokya was made into coffee extract, and the remaining particles were dried to make coffee scrub particles.

In this example, coffee scrub can be added by about 3% and 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, seven women (5 in their 20s, 1 in their 30s, and 1 in their 50s) were asked to rate their impressions after using the product in three categories: good, somewhat good, and unknown effect. It was processed and evaluated as shown in the table.

As is clear from the above results in Table 1, the cosmetic composition of the present invention was highly evaluated for its scrubbing effect, and was also recognized to have sufficient usefulness in the overall evaluation.

(Effect of the invention) As explained above, the coffee-containing cosmetic of the present invention is
Since the scrub agent is made of coffee particles with appropriate hardness, it has the advantage of being highly effective as a scrub and not overly irritating the skin. Furthermore, the faint coffee aroma upon use is very desirable as a cosmetic.

The present invention can be applied to various cosmetics other than those described in the Examples.
