Description

TECHNICAL FIELD The present invention relates to a skin cleanser composition used for cleansing the skin, and a skin cleanser filled with the composition in a container.

BACKGROUND ART Conventionally, skin cleansing compositions containing a scrubbing agent have been provided in anticipation of an effect of removing dirt on the skin and a massage effect of moderately stimulating the skin. As the scrub agent to be used, polyethylene powder, walnut shell particles, crystalline cellulose, and the like, which exhibit excellent effects as described above, are widely used.

However, while these general-purpose scrubbing agents are excellent in the effect of removing dirt from the skin and the effect of massaging the skin, depending on the size and amount of the particles to be blended, they may give unpleasant skin irritation during washing, or give a feeling of foreign matter. There is a problem that it is inferior in the effect of imparting a smooth touch or a smooth touch to the skin after washing.

In recent years, various scrubbing agents have been proposed to solve the above problems, but new problems have arisen. For example, plastic scrubs are inexpensive and can be modified with various shapes and additives to control skin contact. be. Highly biodegradable cellulose scrubs and natural scrubs obtained by crushing apricot husks are irregular in shape and cannot be controlled in hardness, making it difficult to control the feel on the skin. Moreover, the scrub made of high-melting paraffin beads is spherical and hard, and is not satisfactory from the viewpoint of controlling the scrub feeling (feeling on the skin).

US Pat. No. 5,300,001 discloses a skin cleanser containing a cleansing body containing at least 50% by weight of hydrogenated castor oil. However, there is room for improvement from the standpoint of giving a strong feeling to the skin when it comes into contact with the skin during cleansing and causing unpleasant skin irritation.

(Examples and Comparative Examples)
After preparing the skin cleanser compositions of Examples 1 to 11 and Comparative Examples 1 to 5 according to the compositions (blending amounts) shown in Table 1, the compositions were filled into 30 g capacity tube containers, and the following evaluations were performed.

<Evaluation of usability>
Using each sample obtained in Examples and Comparative Examples, the following use test was conducted in the form of a face wash by a male sensory evaluation panel of 10 men, and the feeling of use was evaluated.

After thoroughly wetting the entire face with warm water at 40°C, take 1 g of the sample on the palm of your hand, lather it with a small amount of warm water, apply it to the entire face and wash the face by rubbing it with the palm for 30 seconds, then wash with warm water at 40°C. I washed it off thoroughly. The evaluation was carried out by evaluating the "scrubbing feeling" and "feeling good on the skin" at the time of washing the face, and performing sensory evaluation according to the following evaluation criteria. For the evaluation, the evaluation result obtained by the largest number of people was taken as the score of each sample.

Evaluation Criteria for Feeling of Scrubbing A (excellent): Existence of scrubbing (particles) is felt strongly.
B (Good): Presence of scrub (particles) is clearly felt, but less than A.
C (Poor): Existence of scrub (particles) is hardly felt.

Evaluation Criteria for Feeling Good on Skin A (excellent): Almost no unpleasant stimulation and/or foreign body sensation is felt.
B (Good): Slightly uncomfortable irritation and/or foreign body sensation, but within an acceptable range.
C (poor): An uncomfortable stimulus (pain) and/or foreign body sensation is felt.

<Evaluation of scrub stability>
The 30 g capacity tube container packed product was stored at 40° C. for one month, and about 1 g of the sample was discharged from the tube to evaluate the scrubbing feeling. The evaluation was carried out by washing the face in the same manner as in the "evaluation of feeling in use". For the evaluation, the evaluation result obtained by the largest number of people was taken as the score of each sample.

Evaluation Criteria for Scrubbing Stability A (stable): No change in scrubbing feeling.
B (Good): There is a slight change in scrubbing feeling, but within an acceptable range.
C (unstable): The feeling of scrubbing is greatly deteriorated, or the scrubbing agent has an adverse effect on other ingredients.

From the results in Table 1, it can be seen that the skin cleanser composition of the present invention, in which a scrub agent containing a predetermined fatty acid ester is blended, does not cause unpleasant skin irritation when cleansed, and is excellent in removing dirt. In Comparative Example 5, since no scrubbing agent was blended, the "scrubbing effect" and stability were not evaluated.
