Description

  INDUSTRIAL APPLICABILITY The present invention provides a scalp and a hair cosmetic product that generate foam cracking sound (cracking sound) when heat or shearing force is applied to a foam coating film discharged from an aerosol formulation and that is excellent in usability even when spread on hair. (Scalp hair cosmetics)

  BACKGROUND ART Conventionally, there has been known a technique of a cracking foam composition that forms a crackling foam by foam breaking when sprayed from an aerosol formulation in a mist or foam form. Patent Document 1 describes a cracking foam composition in which a stock solution contains water, a surfactant, an oil component and a lower alcohol, and uses a mixture of a low HLB surfactant and a high HLB surfactant. ing. Although the composition described in Patent Document 1 can enjoy the bubble-breaking sound without applying pressure and without applying a shearing force for a predetermined time, but in terms of a cracking effect. Not enough.

  Patent Document 2 comprises a stock solution containing a water-soluble polymer, a surfactant and a lower alcohol, and a liquefied gas, and the liquefied gas having a boiling point of −5 ° C. or less is contained in an aerosol composition in an amount of 38% by weight or more. Aerosol compositions are disclosed. Further, in Patent Document 3, an IOB value (Inorganic Organic Balance: Inorganic / Organic) of an oily base, which consists of a stock solution containing an oily base, a water-soluble polymer, a surfactant, and water, and a liquefied gas An aerosol composition having a composition balance of 0.2 to 0.5, an oily base content of 3 to 30% by weight in the stock solution, and a composition ratio of the stock solution and the liquefied gas of 50/50 to 10/90. It is disclosed. Since the aerosol compositions of Patent Documents 2 and 3 contain a water-soluble polymer, when they are discharged, they become foams having a slightly viscous property, and when shear is applied to the foams with a fingertip or the like, a large foaming sound is emitted, and Although a pleasant feel is obtained, there is a problem that the cracking effect does not last. Further, since the compositions described in these documents are not for hair, there are problems that the hair becomes sticky after application and the hair becomes dry after application and drying.

  In Patent Document 4, an undiluted solution is an active ingredient, a polyoxyethylene addition type fatty acid ester and a nonionic surfactant having an HLB of 8 to 19, a monohydric alcohol having 2 to 3 carbon atoms and water, and a liquefied gas A foamable aerosol composition which is a poorly water-soluble liquefied gas and has a mixing ratio of a stock solution and a liquefied gas of 60/40 to 10/90 is described.

  In addition, in Patent Document 5, an ester oil is added to give a rich luster to hair, and it has excellent set-holding power, and also has a smooth feel and excellent combability when wet and dry, and can be applied to the palm. Although a hair setting composition having less stickiness to the hands when taken is disclosed, no mention is made of use on the scalp, and there is no suggestion of use on both the scalp and hair.

Japanese Patent No. 3665925 Japanese Patent No. 4173034 JP, 2009-173613, A International Publication No. 2012/033196 JP, 2001-64124, A

  A so-called cracking foam composition is less likely to be broken by a formulation containing a large amount of alcohol, and the cracking effect is low. The composition described in Patent Document 4 has a large alcohol content of 5 to 40% by mass, and therefore the cracking effect is low. When the alcohol content is reduced to enhance the cracking effect, the formulation freezes due to the heat of vaporization of gas. For this reason, when used on the scalp, it is also necessary to avoid reducing the amount of alcohol too much because it is necessary to avoid frostbite.

  In order to enhance the cracking effect, it may be possible to add a water-soluble polymer as described in Patent Documents 2 and 3, but if the water-soluble polymer is added as described above, the cracking effect is sustained. There is a problem that it is difficult. Further, when the water-soluble polymer is blended, the water-soluble polymer itself has stickiness, and thus the stickiness of the hair when spread on the hair deteriorates usability. Furthermore, when a water-soluble polymer is added, the stock solution may separate if it is made into a can after the stock solution has been stored for several days, so the stock solution may be uniformly filled unless the stirring step is performed again. Can not. In particular, when a drug is added to a hair cosmetic composition, the stability of the drug is impaired.
