Description

  The present invention relates to a cleaning composition. More specifically, the present invention relates to a detergent composition that has a mild effect on hair and skin, has good foaming power, and has little discoloration of hair-colored hair.

2. Description of the Related Art Conventionally, anionic surfactants in which about 2 to 4 mol of ethylene oxide (hereinafter abbreviated as EO) is added to a higher alcohol, for example, lauryl alcohol, and then converted into a sulfate ester salt are widely used in the cleaning field. . However, for those used on a daily basis, there is a need for surfactants that are safe for the human body, especially mild to the action on the hair and skin. As mild surfactants, amino acid-based and phosphate ester-based surfactants are required. Many anionic surfactants and those containing amphoteric surfactants have been proposed. In addition, an adduct of a specific alkanediol with an alkylene oxide (hereinafter abbreviated as AO) or a combination of a surfactant made of a sulfate thereof and an alkyl glucoside has reduced irritation and has excellent foaming properties. Is disclosed.
On the other hand, hair colors in recent years have become fashion, and many people have dyed their hair and are enjoying fashion. However, once hair is dyed, there is a problem that the color of the hair color tends to fade due to shampoo. In response to this, an improvement by a shampoo formulation and a method of improving depending on the type of surfactant have been proposed (see Patent Documents 1 to 3).

  As clearly shown in Tables 1 and 2, the detergent compositions (Examples 1 to 12) containing the amidobetaine type amphoteric surfactant (A) and the anionic surfactant (B) within the scope of the present invention were used in the skin. Stimulation is low enough, foaming power is abundant, and even if it is washed against hair color dyed hair, there is little discoloration. On the other hand, Comparative Examples 1 to 10 do not sufficiently satisfy the performance items.

  The cleaning composition of the present invention is suitable as a household cleaning agent (clothing detergent, hair cleaning agent, dish detergent, etc.) and an industrial cleaning agent (metal, precision parts, etc. cleaning agent).
