Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a skin cleansing moisturizing lotion.

[0002]

2. Description of the Related Art Conventionally, lotion has been used, for example, in "Latest Cosmetic Chemistry, Revised and Supplement II" edited by the Japan Cosmetic Engineers Association (1992.
As described in 7.10), polyhydric alcohols such as glycerin for preventing the skin from drying and humectants such as collagen, ethanol for giving a refreshing feeling and a slight bactericidal action, and a good feeling in use. Fragrances and pigments for
Astringents for tightening the skin, emollients for softening the skin, nutrients for the skin, preservatives and bactericides, etc., but their contents are very small except for polyhydric alcohols and ethanol. That is, it is no exaggeration to say that the main components of the lotion are polyhydric alcohol and ethanol.
The viscosity of the lotion is usually equal to or lower than that of water, as can be seen from the composition.

[0003]

However, since the ethanol contained in the conventional lotion irritates the skin, people with inflammation of the skin feel pain. In addition, the upper limit of the formulation is specified in order to have an anti-cosmetic adverse effect on the skin such as generation of spots of fragrances, pigments and antiseptic germicides, but in spite of this, the skin is irritated by irritation such as rash. Or cause a problem. Furthermore, since the amounts of humectants, astringents, and emollients other than polyhydric alcohols are extremely small, their effects are not only lost in a short time, but also the effect of cleansing the skin is considered at all. The fact is that they have not.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems. The gist of the present invention is that a reverse osmosis treatment and an ion exchange treatment make it possible to use cations, anions, and the like.
Water from which suspended matters and bacteria have been removed, and a humectant containing glycerin and amino acids as main components or a humectant containing a polysaccharide having a carboxyl group or a moisturizer containing a polysaccharide having a glucosamine group as a component. A skin cleansing moisturizing lotion comprising at least one moisturizing agent and a thickening agent, containing no preservative and bactericide, and having a viscosity of 500 to 5000 centipoise.

Hereinafter, the present invention will be described in detail. The skin cleansing moisturizing lotion (hereinafter referred to as the present lotion) according to the present invention is based on the basic technology of keeping the skin clean and maintaining a physiologically and cosmetically healthy state if sufficiently moisturized. It has been developed and has completely different properties from conventional cosmetics. That is, the present lotion is a highly viscous liquid and does not contain a pigment, a fragrance, an antiseptic and the like which may give a harmful irritation to the skin.

[0006] Therefore, the mechanism for keeping the skin clean with the lotion according to the present invention promotes the exfoliation of the stratum corneum to be exfoliated by frequently rubbing the skin with the lotion, and a moisturizer and a moisturizer on the skin. The act of physically blocking external stimuli by forming a thin film of thickener.
The mechanism by which the lotion moisturizes the skin is that the thin film moisturizes the skin by relaxing the vapor pressure difference between the moisture in the epidermis and the moisture in the air.

The reason why the lotion is a highly viscous liquid is closely related to its use. That is, for example, when used on the face, the lotion is applied to the entire palm of the hand, and the face is then rubbed as if the face was washed. At this time, if the face is not viscous, the lotion will spill out without even the rubbing. Therefore, according to the research, No. 2 was measured using a B-type viscometer. The viscosity measured under the conditions of 2 rotors, 12 revolutions per minute and room temperature was 50.
It was found that if it was less than 0 centipoise, there were many spills.

The humectant and the thickener used in the present lotion may be any of the substances described in the standard of cosmetic raw materials and in the specification of the compounding ingredients according to the type of cosmetic, as long as they have a humectant or a thickener. As the humectant, a collagen having a small amount of an effective amino acid as a main component, a polysaccharide having a carboxyl group, or a hyaluronic acid salt having a glucosamine group is desirable. As a thickener, a vinyl group having a large effect is effective. Alternatively, a substance or polysaccharide containing an acryl group is desirable. The collagen containing an amino acid as a main component may be any of commercially available collagens, such as water-soluble collagen and hydrolyzed collagen, to which no preservative disinfectant is added.

The polysaccharide having a carboxyl group includes
Reduce the frictional resistance when applying this lotion to the skin with fingers, and may be any of viscous seaweed powder, seaweed extract and sodium alginate, but seaweed extract and alginic acid in that they have low odor. Sodium is preferred. The hyaluronate having a glucosamine group may be either one extracted from a cockscomb or one produced by a fungus, but a sodium salt having high solubility in water is desirable. Further, as the substance containing a vinyl group, any substance may be used as long as it is a water-soluble substance such as polyvinyl alcohol, but a carboxyvinyl polymer having a large thickening effect in a small amount is desirable. As the substance containing an acrylic group, any substance may be used as long as it is a water-soluble substance such as sodium polyacrylate.

EXAMPLE A humectant and a thickener are added to water from which cations, anions, suspended matters and bacteria have been removed by reverse osmosis treatment and ion exchange treatment, and a lotion having the composition shown in Table 1 is obtained. Created. Nos. Of these lotions were measured at room temperature using a B-type viscometer. Viscosity measured under the conditions of 2 rotors, 12 revolutions per minute, 1 face of 10 women in their 40s
After rubbing with 0 ml of lotion for 3 minutes and wiping with a towel, rub the forehead with a 3 cm wide, 5 cm long nonwoven fabric,
The nonwoven fabric was washed with 100 ml of 1% Triton-Ekss solution, and the skin cells in the 1% Triton-Ekss solution were stained with a methylene blue / rhodamine solution (1: 1) to count the number of skin cells. The faces of 10 women were rubbed and washed with 10 ml of lotion for 3 minutes and wiped with a towel, and the moist feeling after 5 hours is shown in Table 2. As a result, No. 1 of the present invention example. 1 to 5 are comparative examples N
It can be seen that both the cleanliness and the moisturizing property are excellent as compared with o6-7.

As described above, by using the skin cleansing moisturizing lotion according to the present invention, the skin can be kept clean and sufficiently moisturized. It has an effect of maintaining an extremely excellent skin beauty which does not contain any of pigments, fragrances, and preservatives which may give harmful irritation.
