JP6348026B2 - Non-aerosol foamer - Google Patents

Description

  The present invention relates to a hair styling agent in a non-aerosol foamer container.

  The hair styling composition has various objectives and performance aspects, such as the hairstyle to be stipulated, improved touch after styling, maintaining the hairstyle, and re-styling properties once the hairstyle has collapsed. Proposals have been made so far. Specific dosage forms of the hair styling agent include a mist-like hair styling agent, a foamy hair styling agent, and a wax-like or gel-like hair styling agent. Among these, the foam-like hair styling agent has a large specific volume and is a dosage form that is easily accepted by users in terms of ease of application to hair.

  For example, Patent Document 1 contains polyoxyalkylene alkyl glucoside, a hair fixing polymer compound (film-forming polymer) and polyethylene glycol, and has good hair styling, and can impart smoothness and good touch to hair. A hair styling agent is described, and as an example, an aerosol-type foam hair styling agent is disclosed (Example 2).

  On the other hand, from the viewpoint of being environmentally friendly, in recent years, a non-aerosol foam-like hair styling agent has also been developed. For example, Patent Document 2 describes a non-aerosol foam hair styling agent containing a film-forming polymer, a polyethylene glycol having a specific molecular weight and a foaming surfactant.

  In addition, Patent Document 3 describes a state before improving the foam quality such as ease of conforming to dry hair, holding of foam, and the bulkiness of the foam, and disturbing the wave of hair that has been disturbed after wave perm is applied. A non-aerosol foamed container hair styling agent containing polyoxypropylene alkyl glucoside, a film-forming polymer, and a surfactant in a certain ratio is described as a foam hair styling agent that has an excellent effect of recovering the hair.

  A non-aerosol foam-like hair styling agent generally forms bubbles by passing it through a foam homogenizing means such as a net after mixing with gas and liquid. For this reason, adjustment of the foam quality discharged from the container is a big subject, and it is influenced by the compounding quantity of the component in a composition, the net hole size of a discharge mechanism, the environmental condition at the time of discharge, etc. For example, the hair styling agent in a non-aerosol foamer container described in Patent Document 3 becomes less foamy as the concentration of the film-forming polymer is increased, and the familiarity with the hair is reduced. Therefore, it is partially concentrated when applied to hair. There was a problem that it was easy to stick. Further, as the net hole size of the foam discharge mechanism becomes coarse, the foam quality and the foam persistence become worse, and the foam quality particularly when discharged at a high temperature or low temperature is not sufficient.

  Therefore, the present invention can maintain a good foam quality even when the film-forming polymer is at a high concentration, and can be spread evenly over the entire hair, and the size of the net hole size of the non-aerosol foamer container, and the high or low temperature environment. The present invention relates to a hair styling agent that is not affected by the use underneath, has good foam quality and foam, is well-familiar with hair, and has an excellent effect of restoring the bundle of permawave bundles.

That is, the present invention provides a hair styling agent in a non-aerosol foamer container containing the following components (A) to (C).
