Description

  The present invention relates to a composition for a sesame detergent. More specifically, the present invention relates to a composition for a gorge cleaning agent in which aggregates (debris) such as eraser debris are generated when applied to the skin and rubbed.

  Cosmetics called gommage generate agglomerates (debris) such as eraser debris by rubbing with fingertips, palms, or tools after being applied to the skin. The purpose is to exert a so-called gommage effect by adsorbing and removing the exfoliated keratin and skin dirt.

  Attempts using a water-soluble polymer that forms a film have been proposed as cosmetics that exhibit such a gommage effect. Specifically, for example, a gommage cosmetic containing a film-forming polymer, crystalline cellulose, and a polyhydric alcohol (see Patent Document 1), a gommage containing a film-forming water-soluble polymer, and silicic anhydride. Cosmetics (see Patent Document 2), gommage cosmetics (see Patent Document 3), carboxyvinyl polymer containing a film-forming water-soluble polymer, water-absorbing resin particles, a monovalent lower alcohol, and water. And sesame cosmetics containing polyhydric alcohol and water-insoluble powder (see Patent Document 4) have been proposed.

  However, although these attempts can exert a gamage effect, an excellent cleaning feeling can be obtained when a high amount of a cleaning component such as a nonionic surfactant is added to further improve the cleaning feeling, but slipping on the skin is possible. There is a problem that the property is increased and the generation of aggregates (debris) such as eraser debris is suppressed or delayed, and a sufficient gommage effect cannot be exhibited. Therefore, it has been difficult to obtain a gamage cosmetic that sufficiently satisfies both an excellent gamage effect and an excellent cleaning feeling.

  Therefore, the object of the present invention is to generate agglomerates (debris) such as eraser debris, which is the greatest feature of gorgeous cosmetics, to fully exhibit the excellent gorgeous effect and to have an excellent cleaning feeling.

(Preparation of each sample)
According to the composition described in Tables 1 and 2, after preparing the compositions for sesame detergents of Examples 1 to 6 and Comparative Examples 1 to 6, they were each filled into a transparent tube container having a capacity of 50 g and subjected to the following evaluation test. . The results are shown in Tables 1 and 2, respectively.

(Test Example 1: Evaluation of dispersion stability)
Each sample obtained in Examples and Comparative Examples was stored in a thermostat at 50 ° C. for 1 month. The dispersion state of the fibrous cellulose after one month was visually evaluated according to the following evaluation criteria. In addition, about the sample which does not contain fibrous cellulose, evaluation of dispersion stability is not performed.

<Evaluation criteria for dispersion stability>
◎ (Very good): There is no change immediately after preparation, and it is uniformly dispersed ○ (Good): Very few aggregates are observed but dispersed Δ (insufficient): Clear aggregates are observed X (Poor): Sedimented and not dispersed at all

(Test Example 2: Evaluation of aggregate (waste) formation)
10 professional panelists apply 0.5 g of each sample obtained in the examples and comparative examples to the inner side of the forearm and rub the sample with their fingertips to evaluate the speed at which aggregates (dust) are formed. did. In addition, in the evaluation of Test Example 1, the sample with the result “x” is not evaluated for the formation of aggregates (debris).

  The evaluation was conducted by rubbing at a width of about 10 cm, and the number of reciprocations within which the aggregate was formed was tested, and the average value of the test results of the evaluation panel was used as the evaluation result of each sample.

<Evaluation criteria for aggregate (waste) formation>

(Test Example 3: Evaluation of use feeling)
Ten male sensory evaluation panels performed the following usage tests in the form of a face wash using each sample obtained in the examples and comparative examples, and evaluated the feeling of use.

  Take 3.0 g of sample on dry palm, apply to entire dry face, wash face for 1 minute while rubbing entire face with palm, then rinse thoroughly with warm water of 40 ° C and wipe off moisture on face with towel dry The “gommage effect” at the time of washing the face and the “feeling of washing” after towel drying were evaluated, and sensory evaluation was performed according to the following evaluation criteria.

  The evaluation of the “Gomage effect” is based on the evaluation of the “Gomage effect”, indicating that the fibrous cellulose has good cohesiveness when washing the face, and that the formed agglomerates have removed the old keratin and sebum stains. "Is good.

  The evaluation of “cleaning feeling” was defined as “cleaning feeling” when the skin after towel drying was clean and refreshed and had a moderately smooth feel.

<Evaluation criteria for gommage effect>
◎ (Very good): More than 9 out of 10 people can feel the gonage effect enough ○ (Good): 6-8 out of 10 people can feel the gamage effect enough Answer △ (insufficient): 3 to 5 out of 10 people can feel the gommage effect sufficiently × (bad): 2 or less of 10 people can feel the gommage effect enough answer

<Evaluation criteria for cleaning feeling>
◎ (very good): 9 or more out of 10 responded that they had excellent cleaning feeling ○ (good): 6 to 8 out of 10 responded that they had excellent cleaning feeling △ (insufficient) : 3 to 5 out of 10 responded that they had excellent cleaning feeling × (defect): 2 or less of 10 persons answered that they had excellent cleaning feeling

  From the results of Tables 1 and 2, it can be seen that the compositions for sesame detergents of each Example are superior in dispersion stability of fibrous cellulose as compared with those of each Comparative Example. In addition, it can be seen that the fibrous cellulose after application has good cohesiveness and can sufficiently exhibit an excellent gommage effect, and exhibits an excellent cleaning feeling.

  On the other hand, in Comparative Examples 1-4 which do not satisfy the essential component of this invention, it turns out that the effect of this invention cannot fully be exhibited. Further, in Comparative Examples 5 to 6 in which the component (B), which is an essential component of the present invention, is replaced with xanthan gum, which is a non-synthetic thickening polymer, similarly, excellent dispersion stability and excellent gommage effect. It has been difficult to obtain a composition for a sesame detergent that satisfies both requirements sufficiently. Also from this, in the composition for gorge detergent, in order to ensure the dispersion stability of the fibrous cellulose and sufficiently exhibit the gorge effect, and to obtain an excellent cleaning feeling, the essential component of the present invention is used. It can be understood that the combination is essential.
