DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to germicidal compositions, preferably, germicidal compositions for the body. The germicidal compositions for the body produce low levels of skin irritation and have excellent sterilizing properties and can be used in the disinfection and sterilization of hands and fingers; the disinfection and sterilization of human skin, such as, for example, facial skin and the human scalp, and hair, such as, for example, hair of the head; and the disinfection and sterilization of animal skin.
BACKGROUND ART
Quaternary ammonium salts have excellent sterilizing power. They have been used for a variety of conventional purposes, including the sterilization and disinfection of buildings and environments, such as, for example, barns and food plants, and the antisepsis of wood. They have also been used for the sterilization of hands and fingers and for the sterilization of skin upon surgical operation.
Unfortunately, however, quaternary ammonium salts have a tendency to be highly irritable to the skin and have a tendency to cause hand chapping or eruption when used ordinarily. As a result, containing quaternary ammonium salts are limited in their concentration and range for ordinary everyday use. Therefore, they have not produced sufficiently effective results when used for the skin or the like.
With the intent of coping with such problems, a disinfectant antiseptic wherein the counter anion of a quaternary ammonium salt is variably changed and which produces reduced skin irritation is disclosed in Japanese Patent Laid-Open No. 218605/1990.
However, these quaternary ammonium salts are not uniform in their effects, and consequently, stable effects cannot be obtained.
Therefore, there exists a demand for a germicide, preferably a germicide for the body, which produces reduced or little skin irritation, and has greater safety and excellent sterilizing power.
DISCLOSURE OF THE INVENTION
Accordingly, after extensive research, one object of the present invention is a germicidal composition, preferably a germicidal composition for the body, which produces very low levels of skin irritation and exhibits excellent sterilizing power.
Another object of the invention is a germicidal composition, preferably a germicidal composition for the body, comprising by mixing, in a specific proportion, two quaternary ammonium salt compounds, each of which comprises a specific counter ion, which produces remarkably little skin irritation and has excellent sterilizing power.
Another object of the present invention is a germicidal composition, preferably a germicidal composition for the body, which produces little skin irritation, excellent sterilizing power and detergency.
Another object of the present invention is a germicidal detergent composition, preferably a germicidal detergent composition for the body, comprising a composition comprising quaternary ammonium salt(s) in combination with a surfactant such as, for example, an alkyl glycoside or sugar amide.
Still another object of the present invention is a germicidal composition, preferably a germicidal composition for the body, producing even less skin irritation than the above mentioned compositions, comprising a quaternary ammonium salt(s) and a humectant such as, for example, sorbitol or glycerin.
Another object of the present invention is a method for washing, preferably the skin or hair, comprising applying a germicidal or germicidal detergent composition of the present invention.
Another object of the present invention is a method for sterilizing, preferably the skin, comprising washing the skin with a germicidal or germicidal detergent composition of the present invention.
These and other objects of the present invention are made possible by germicidal compositions, preferably for the body, which exhibit excellent sterilizing power and detergency and little skin irritation. The present germicidal compositions are ideal for use on the skin or hair of human bodies such as fingers, hands, facial skin, hair of the head or scalp, and also fo
