Description

  The present invention relates to a hair cosmetic composition, a method for using the same, and a hair cosmetic product. More particularly, the present invention relates to a hair cosmetic composition that is applied to hair by being discharged in a foam form from a non-aerosol foamer container, a method for using the same, a hair cosmetic composition, and a non-aerosol foamer container. The present invention relates to a hair cosmetic product comprising the composition.

  It is known to use hair cosmetics such as hair dyes and hair bleaching agents in a foamy dosage form when used. In general, when these hair cosmetics are used in a foamy dosage form, it is easy to apply evenly and uniformly to the hair, and when using a gel-like or cream-like hair cosmetic that is widely used. The advantage of eliminating the need for hair blocking in the case can be expected.

  Hair cosmetics used in foamy dosage forms can be broadly classified into aerosol types and non-aerosol types. The aerosol type uses a propellant such as a liquefied gas and makes the dosage form foam by forming bubbles using the aerosol. Non-aerosol type, without using a propellant, forms a bubble that takes in air using a pump foamer, squeeze foamer or other non-aerosol foamer container (hereinafter also simply referred to as “former container”), Make the dosage form foamy. A non-aerosol foamer container is preferred from the standpoint that the structure of the container for forming a foamed dosage form is simple and advantageous in terms of cost and that there is no danger during storage and handling.

JP 09-136818 A JP-A-10-287534 JP 2007-291015 A JP, 2008-291020, A The above-mentioned patent documents 1 and patent documents 2 disclose an oxidation hair dye composition or a hair dye composition which is used in a foam form with aerosol.

  By the way, the foam-type hair cosmetic discharged from the non-aerosol foamer container has a problem that the brightness and dyeing of the hair are not always satisfactory. In order to cope with this problem, conventionally, for example, an attempt has been made to blend a linear higher alcohol as in the two-part foamy hair dye composition disclosed in Patent Document 2.

  However, when a straight-chain higher alcohol is blended, it becomes an emulsifying agent due to the interaction with the surfactant. Therefore, aside from aerosol type ones such as the foamy hair dye composition of Patent Document 2, The aerosol type hair dye has a problem that it is difficult to discharge from a non-aerosol foamer container and it is difficult to obtain good foam.

  In this regard, myristyl alcohol (carbon number 14) having a short alkyl chain is advantageous in that it can constitute a solubilizing or dispersing agent even if it is a linear higher alcohol. However, there has been a problem that it is not easy to disperse myristyl alcohol well in a solubilized or dispersed preparation. Hair cosmetics with poor dispersibility of myristyl alcohol cannot form good foam and are likely to sag.

  Therefore, the present invention is a hair cosmetic that is configured as a hair dye or a hair bleaching agent and is ejected from a non-aerosol foamer container in a foamed form, which has excellent dispersibility of myristyl alcohol and good lightness to hair. It is a problem to be solved to provide a hair cosmetic composition that is excellent in hair dyeing.
