Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solvent for cleaning human body and a composition containing the same,

The present invention relates to a solvent for cleaning human body parts such as skin and hair, a composition containing such a solvent, and a method for cleaning human body parts such as skin and hair using such a composition.

Generally, a human body cleaning product is a product to clean and clean the contamination of human body parts such as skin and hair, and is used not only for cleaning the contamination of human body parts such as skin and hair, but also for controlling moisture and nutrients It is also used for the purpose of keeping the human body parts such as skin and hair healthy and giving gloss.

Typically, human body cleansing products are sold in various forms such as bar soaps, creams, lotions, gels and the like, and the cleaning efficiency of these products, skin texture, mildness to the skin and mucous membranes of hair or eyes, In order to satisfy consumers, research and development of products are continuing. The human body cleansing products, which are considered to be ideal, clean the contamination of human body parts such as skin and hair, and hardly or completely stimulate the human body parts such as skin and hair and excessively dry the skin and hair even in frequent use. Not a product.

The contamination of human body parts such as the skin and hair includes aqueous contamination and oily pollution. Such contamination is not only contamination of the external environment and human body but also various components of makeup products used for skin, wax used for hair, spray And hair styling products. However, the components of the makeup product and the components of the hair styling products are not easily cleaned compared to the external environment and the contamination from the human body, and various types of human cleansing products that can easily clean them are being released.

Among these human body cleaning products, there are an emulsion type product, a water-based type product, and a oil-based type product for cleaning the contamination of the skin.

Examples of the emulsion type human cleansing products are cleansing lotion and cream, which contain 20 to 70% by weight of oily components, and are known to have excellent cleansing effect on cosmetics and excellent softness and massage effect in use. However, since the emulsion type uses a large amount of oil, it is necessary to wipe off with a tissue off because a lot of oil is left on the skin after use and can not be completely washed out with water. Thus, there is a fear that skin irritation may occur due to physical stimulation. It is inconvenient to perform secondary cleansing using foam cleansing or soap due to the oily sensation remaining afterwards.

In addition, the aqueous type product can be divided into a microemulsion gel type and a cleansing gel type, wherein the content of the surfactant is relatively high, i.e., 10 to 40% by weight. Since the microemulsion gel type contains a large amount of oil and a nonionic surfactant, the cleansing effect is excellent, but there is a feeling of stiff feeling and an inconvenience that the oil remains on the skin even after use, so that it is difficult to wash it completely with water. On the other hand, since the cleansing gel type does not use oil but uses an anionic surfactant, it can be easily washed with water and can feel fresh feeling, but the cleansing effect for removing makeup is poor, and skin irritation may occur due to anionic surfactant .

In addition, the cleansing oil, which is a oil type cleansing product of the above-mentioned type, is excellent in cleansing effect because it uses almost 100% oil. However, since the oil having low viscosity is used, there is inconvenience and feeling of use is low, There is a problem that it is difficult to wash with water. In addition, there is an inconvenience that it is necessary to perform secondary cleaning with foam cleansing or soap.

On the other hand, there are shampoo, wipe-out mist, foam, powder spray type product, and wet tissue type product which rubs the hair and rubs the contamination among the human body cleaning products to clean the contamination of hair. However, products other than shampoo are focused on cleaning dirt and human-derived contaminants adsorbed on the hair, and human body cleaning products for cleaning hair styling products are not specialized. In this situation, consumers can use a method of increasing the efficiency of the shampoo by applying and rinsing the shampoo rinse in order to clean the hair styling product which is not cleaned well with the shampoo, or the method of applying the human body cleansing products to the hair . However, the first method is somewhat cumbersome. In the second method, the components of the human body cleansing products for skin remain in the hair and the accessibility to the hair and scalp as a whole is low.

Also, it is not preferable to apply a solvent used for dry cleaning to clean hair styling products, or a solvent used for washing pretreatment washing, which effectively cleans only specific stains of fibers or clothes, to skin or hair. Turpentine-based solvents such as petroleum, chlorine, glycol ester, cyclic silicone, silicone, fluorine, and limonene used for dry cleaning and partly stain remover used for washing pretreatment and washing are controversial to apply to human body And the feeling and smell that are felt when they are used for skin or hair can cause discomfort and dizziness, making it difficult to apply to skin or hair. In addition, these solvents have a disadvantage in that they have a low solubility in water and therefore have a limitation in cleaning aqueous contamination of the skin or hair. Therefore, restrictions on use of these solvents are being tightened because of the great risk of fire or explosion.

Accordingly, a problem to be solved by the present invention is to provide a method for cleaning a human body, which is safe to the human body and environment without irritating the skin as well as having an excellent detergency to such an extent that secondary cleaning is unnecessary, A composition containing such a solvent, and a method for cleaning body parts such as skin and hair using such a composition.
