Cleanser composition, method for generating foam, foam, and method for washing hair

Abstract

Provided is a cleanser composition containing water and a surfactant. The surfactant constitutes between 0.4% and 12% of the cleanser composition by mass. The viscosity of the cleanser composition is between 5 mPas and 1,500 mPas at 30 DEG C. When foam is generated by mixing air into the cleanser composition, the viscosity of the foam after 10 seconds is between 40 mPas and 100 mPas at 30 DEG C and the mean diameter of bubbles in the foam after 30 seconds is between 10 [mu]m and 100 [mu]m.

Description

technical field [0001] The present invention relates to a cleanser composition, a method of forming a foam, a foam, and a method of cleansing hair. Background technique [0002] Conventionally, solid cleansers, liquid cleansers, etc. have been known as cleansers for washing hair, skin, etc., but foam cleansers have been used in order to easily generate foam. [0003] JP 2007-161906 A discloses a composition for a foam cleanser comprising an anionic surfactant, a fatty acid alkyl alcohol amide, and a polyalkylene terephthalate. Moreover, the foam cleanser which filled the composition for foam cleansers in the non-aerosol type foam discharge containers, such as a pump foamer and a squeeze foamer, was disclosed. [0004] However, since the content of the surfactant in the composition for foam cleansers is large, there is a problem that the discharge amount of the surfactant by washing|cleaning becomes large. On the other hand, if the content of the surfactant in the compositi...

Problems solved by technology

[0009] However, in the foam generation method using a pump foamer, there is a problem that the texture of the generated foam cleanser is rough, and the desired creamy foam cannot be generated

Since the air (air bubbles) contained in such coarse-textured foam is large, the foam is easily broken during cleaning, so the durability of the foam is poor, and there are also problems with the satisfaction of cleaning.

In addition, in the foam generation method using a pump foamer, the mesh member installed in the spray tank is clogged over time due to the residue and drying of the original solution of the cleaning agent, and the application of the cleaning agent is limited, and there are also problems depending on the usage method. The problem of shorter service life caused by different

In addition, replacing the net member is also considered, but since the net member is usually placed deep in the spray tank, the work of replacing the net member is troublesome and unrealistic

[0010] In addition, in the method of generating foam using an aerosol container, liquefied gas is required as a propellant, and since the liquefied gas is generally flammable, there is a problem in terms of safety.

[0011] Furthermore, in the conventional electric foam generation method, since the foamy cleanser generated by the air bubbles sprayed from the foaming stone is not sprayed to the outside until the storage tank is filled, there is a problem until the foam can be taken out. The problem that it takes a long time until the liquid cleaner

In addition, the foam cleanser produced by using foaming stone also has the problem of rough texture and cannot form the desired creamy foam

[0012] In the method of combining the foam generation method using a pump foamer and the foam generation method using an electric motor, it is expected to reduce the clogging of the mesh member, but the texture of the foamy cleanser is rough and the desired cream cannot be obtained. Disadvantages of shaped foam

In addition, there is a problem that the scale of the machine becomes larger
