Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-aqueous gel-type skin cleansing agent having a warm feeling and being excellent in a massage effect such as blood circulation promotion and a cleaning effect. More specifically, it is formed of one or more ethylene oxide group-added nonionic surfactants as a cleaning component, silica gel, and a polyhydric alcohol having 4 or less hydroxyl groups and a molecular weight of 200 or less. The present invention relates to a non-aqueous gel cleaning agent that does not contain water.

2. Description of the Related Art Massage cosmetics and cleansing cosmetics are used to remove skin stains and makeup cosmetics. The massage cosmetics, when applied to the skin, promote blood circulation in the skin, and also have effects such as cleansing and refreshing the skin. In recent years, as such a massage cosmetic, an aqueous gel type has been used because it can be easily rubbed on the skin and a fresh feeling can be obtained. Then, a moisturizing agent such as polyhydric alcohol is added to enhance moisturizing properties, and further a large amount of moisturizing agent is added to impart a warm feeling, and a scrub agent is used for the purpose of cleaning the skin and removing old keratin. Ingenuity such as blending has been made.

Aqueous gels give a viscosity suitable for massage operations, and therefore, polysaccharides such as guar gum, locust bean gum and xanthan gum, semi-synthetic polymers such as hydroxyethyl cellulose, carboxymethyl cellulose and alginate, polyvinylpyrrolidone, carboxyvinyl polymer, It is produced by blending a thickener polymer such as a synthetic polymer such as sodium polyacrylate. The thickener polymer also has the function of stabilizing the dispersion of the scrubbing agent. As the scrubbing agent, granules granulated with a water-insoluble binder, porous spherical cellulose, granules containing sodium chloride as a main component, etc. may be used for the purpose of higher cleaning and exfoliating effect. It is disclosed (JP-A-60-152407, JP-A-63-238008, JP-A-3-123732).

On the other hand, also in cleansing cosmetics, a fresh feeling of use which is a characteristic of gels is preferred, and gels for cleaning and makeup removing have recently taken a large share. As such a cleaning and makeup removing gel, an aqueous gel, an oily gel and an oil gel thickened by using the above-mentioned thickening agent polymer are known. A small amount of oil may be dispersed and mixed in the aqueous gel, but these can be washed off with water and are characterized by a refreshing feeling of use. There are emulsification type and liquid crystal type oily gels, which are well compatible with makeup cosmetics.
The O / W type emulsion and the liquid crystal type can be washed off with water. Oil gel is very familiar with make-up cosmetics and is characterized by a great cleaning power.

However, the gel formed from the thickener polymer has a large temperature dependency of viscosity, and the elongation at the time of application to the skin becomes poor at low temperature, and the fluidity increases at high temperature to increase the gel to the fingers. There are problems that the meltability is poor and that when a scrubbing agent is contained, the sedimentation is observed at high temperature. Moreover, the cleaning effect was inferior. Further, conventionally used scrub agents have a problem that they may cause discomfort, pain and irritation when applied to the skin.

On the other hand, oil gels and W / O emulsion type oily gels cannot be washed with water because the oil phase is a continuous phase. Therefore, after use, it was necessary to wipe them off with a tissue paper or the like and then rewash with a face wash or the like. With O / W emulsion type and liquid crystal type oily gels, it is possible to wash off with water without the above-mentioned wiping operation, but oil components often remain on the skin, and washing with water alone is not enough. Met.

Further, the above-mentioned washing and makeup removing gel is poor in stability against temperature changes, and oil gels may cause separation and separation of washing components at low temperatures. It sometimes caused separation of the components.

Subsequently, a usage test was conducted on the above-mentioned Examples of the present invention and Comparative Examples. In the use test, 20 female panelists aged 20 to 50 were used as one group, and each group was blindly used in Examples or Comparative Examples, and was taken on fingers, stretched on the skin, irritation on the skin, and makeup. A sensory evaluation was performed on the removal effect of the up cosmetics and the washability.
The sensory evaluation was “good; 5 points”, “slightly good; 4 points” regarding the ability to be picked up on the fingers, spread on the skin, and washability.
"Normal; 3 points", "Slightly bad; 2 points", "Bad; 1
"Dot", and "I don't feel the irritation on the skin; 5"
"Point", "Slightly feel; 4 points", "Feel; 3 points",
"Available; 2 points", "Strongly felt; 1 point", "Yes;5" for the effect of removing makeup cosmetics
"Point", "Somewhat; 4 points", "Neither can be said; 3
It was scored by making the evaluation as “point”, “slightly; 2 points”, “not; 1 point”. The results are shown in Table 2 as an average value of 20 panelists.

[Table 2]

In Table 2, all of the groups used in Examples of the present invention were evaluated to be good in picking up on fingers and elongation on the skin. The skin irritation was not felt or felt slightly in any of the use groups. Further, most panelists also evaluated the effect of removing makeup cosmetics as "yes", and almost all panelists evaluated "good" with respect to the washing property.

On the other hand, in the group used in the comparative example, the evaluation on the elongation on the skin was quite good, but in the group used in the comparative example 1 and the comparative example 2, it was evaluated as being slightly hard to pick up. In addition, in Comparative Examples 1 to 3, the makeup removing effect was evaluated to be insufficient, and some irritation on the skin was also observed. This irritation is considered to be caused by the agglomeration of sodium chloride particles over time. On the other hand, in the use groups of Comparative Example 4 and Comparative Example 5, the makeup removal effect was good, but the washability was poor.

Further, in the examples of the present invention, most of the panelists used have realized an appropriate thermal sensation and a good blood circulation promoting effect, and in particular, particles containing an alkali metal salt or an alkaline earth metal salt are blended.
