Description

  The present invention relates to a cracking aerosol composition in which a jetted sprayed material changes from a sherbet state to a cracking foam state, and there is no stickiness and a refreshing feeling of use can be obtained.

  For example, various sprays have been conventionally provided and used as cosmetic sprays, insect repellent sprays, cleaning sprays, and the like. In addition, a cracking aerosol composition has also been proposed in which foaming occurs gradually in the propellant, and the foam formed by the foaming cracks and cracks to form a cracking foam-shaped propellant, In particular, it is widely used in the cosmetic field (see, for example, Patent Document 1 and Patent Document 2).

  Since the jetting substance of the cracking aerosol described in Patent Document 1 is sprayed in a mist or foam form and then adheres to a target site such as skin, there is an effect that a cooling feeling and a refreshing feeling are imparted. Further, the cracking aerosol spray described in Patent Document 2 has an effect that after being sprayed in a foam shape, it adheres to the skin, the hair, and the like, and a refreshing feeling due to a cooling feeling and a bubble breaking sound is imparted.

  In the cracking aerosol composition described in Patent Document 1 and Patent Document 2, a lower alcohol such as ethanol is blended as a solvent, and ethanol has been generally used as a solvent for generating cracking. . However, in the case of cosmetics, there are some people who develop eczema and the like under the influence of ethanol because the propellant is directly attached to the skin and scalp. As a result, some cosmetic sprays prohibit the incorporation of ethanol components to prevent allergic reactions in some products, and there is a demand for the development of new cracking aerosol compositions that do not contain lower alcohols such as ethanol. It had been.

  The present invention solves the above-mentioned conventional problems, and does not adversely affect humans because it does not contain a lower alcohol such as ethanol as a solvent, and the injected sprayed material changes from a sherbet state to a cracking foam state. It is an object of the present invention to provide a cracking aerosol composition that can be changed to provide a refreshing feeling without stickiness.

  The cracking aerosol composition of the present invention made to solve the above problems comprises a solvent for generating cracking comprising an amphiphilic ether alcohol, a surfactant, a thickener, and the balance being water. And the propellant changes from a sherbet state immediately after injection to a cracking foam state. This is the invention according to claim 1.

  The solvent is preferably one or more selected from ether alcohols, and this is the invention according to claim 2.

  The undiluted solution contains solvent: 10 to 30% by mass, surfactant: 0.1 to 2.0% by mass, thickener: 0.1 to 1.0% by mass, with the balance being water. Is preferable, and this is the invention according to claim 3.

  Moreover, it is preferable that the mixture ratio of stock solution: propellant is 1: 0.5-1: 3 (mass ratio), and this is the invention according to claim 4.

  The invention according to claim 1 comprises a solvent for generating cracking comprising an amphiphilic ether alcohol, a surfactant, a stock solution containing a thickener and the balance being water, and a propellant. Since it was made, there is no risk of eczema and the like because there was no ethanol contained in the past. In addition, since the projectile changes from the sherbet state immediately after injection to the cracking foam state, it can be firmly attached to a target site such as skin, and a refreshing feeling due to a cooling feeling and a bubble breaking sound can be imparted.

  In the invention according to claim 2, since the solvent is one or more selected from ether alcohols, it is not necessary to use ethanol, and there is no possibility of generating eczema. Further, ethoxydiglycol, which is one of ether alcohols, is excellent in moisturizing properties and is also excellent as a transdermal absorption accelerator for active ingredients, and can provide a cosmetic product having a high moisturizing effect.

  In the invention according to claim 3, the stock solution contains solvent: 10 to 30% by mass, surfactant: 0.1 to 2.0% by mass, thickener: 0.1 to 1.0% by mass, and the balance. Since it was water, a cracking aerosol composition can be easily prepared.

  In the invention according to claim 4, since the blending ratio of the stock solution and the propellant is set to 1: 0.5 to 1: 3 (mass ratio), the sherbet-like propellant can be obtained without separation of the stock solution and the propellant. Can be injected.

Hereinafter, preferred embodiments of the present invention will be described.
The cracking aerosol composition of the present invention is applicable to cosmetics such as milky lotion, moisturizing liquid, lotion, sunscreen, hair styling, hair tonic and shaving cream.

The cracking aerosol composition of the present invention basically comprises a stock solution and a propellant, and the stock solution comprises a solvent for generating cracking comprising at least an amphiphilic ether alcohol, and a surfactant. And a thickener is contained, the balance being water.
Further, the cracking aerosol composition of the present invention is such that the propellant changes from a sherbet state immediately after injection to a cracking foam state. In the past, there existed only one of either a sherbet state or a cracking foam state, but the present invention provides an aerosol composition that changes from a sherbet state to a cracking foam state and exhibits two modes. Can do.

The propellant used in the present invention is not particularly limited as long as it is a propellant used in ordinary aerosol compositions, and is liquefied petroleum gas (hereinafter referred to as LPG) which is propane, butane or a mixture thereof, LPG and dimethyl ether. (Hereinafter referred to as DME) and the like. In particular, LPG is preferable from the viewpoint of stability.
In addition, when only DME is used as a propellant, since it does not change from a sherbet state to a cracking foam state, it is not preferable.

  In the present invention, amphiphilic ether alcohols are used as a solvent for generating cracking. Conventionally, ethanol was generally used as a solvent for generating cracking, but in the present invention, it was developed for the purpose of providing a cracking aerosol composition that can be applied to cosmetics that prohibit the use of ethanol. As a result, the present inventor has found that ether alcohols can be contained instead of ethanol.

  That is, the amphiphilic ether alcohols are necessary solvents for generating cracking, and it was found that the inclusion of the amphiphilic ether alcohol changes from a sherbet state immediately after injection to a cracking foam state. Therefore, immediately after the injection, the jet is in a sherbet state and feels like a cold solid, but after a few seconds, it changes into a viscous liquid, and foaming gradually occurs in this liquid, and the foam formed by the foaming. Crawls into a cracking foam that breaks down and eventually the liquid component penetrates into the skin. Thus, the present invention provides an unprecedented and completely new type of aerosol composition capable of forming a projectile that changes from a sherbet state to a cracking foam state.

Examples of the amphiphilic ether alcohols include ethoxy diglycol, ethoxy diglycol oleate, bis ethoxy diglycol succinate, diethoxy diglycol, ethoxy diglycol behenate, trisethoxy diglycol phosphate, cyclohexane-1, One or two or more selected from 4-dicarboxylic acid bisethoxydiglycol can be used.
In addition, since ethoxydiglycol has a moisturizing effect, it is preferably blended into cosmetics intended for moisturizing.

  The content of the solvent in the stock solution is preferably in the range of 10 to 30% by mass, particularly preferably in the range of 12 to 25% by mass. If the amount is less than 10% by mass, there is a problem that the propellant mold becomes a sherbet and cracking property is inferior.

The surfactant is nonionic and functions as an emulsifier in the stock solution. As long as the HLB is a nonionic surfactant having 7 to 18, any of those used in ordinary cosmetics can be used.
Specifically, polyoxyethylene cholesterol ether, polyoxyethylene cholestanol ether, polyoxyethylene phytosterol ether, polyoxyethylene phytostanol ether, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbitol fatty acid ester, polyglycerin fatty acid ester, Examples thereof include polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ether, propylene glycol fatty acid ester, ethylene glycol fatty acid ester, and the like, and these can be used alone or in combination.

  The content of the surfactant in the stock solution is preferably in the range of 0.1 to 2.0% by mass. If it is less than 0.1% by mass, there is a problem that the emulsifying power is insufficient, and if it exceeds 2.0% by mass, there is a problem that a sticky feeling or the like occurs.

The thickener is a component that adjusts the viscosity of moisture to increase the stability of cosmetics, and is water-soluble.
Typical examples include xanthan gum derived from microorganisms for natural polymers, mannan and pectane derived from plants, cellulose-based sodium carboxymethylcellulose and vinyl-based carboxypolymers for semi-synthetic polymers, and polyvinyl alcohol for synthetic polymers.

  The content of the thickener in the stock solution is preferably in the range of 0.1 to 1.0% by mass. If it is less than 0.1% by mass, there is a problem that the emulsion stability is insufficient, and if it exceeds 1.0% by mass, there is a problem that a sticky feeling or the like occurs.

  The balance is water. Examples of the water include purified water, ion exchange water, physiological saline, and deep sea water.

  The mixing ratio of the stock solution: the propellant is preferably 1: 0.5-1: 3 (mass ratio). If the propellant is less than this ratio (less than 0.5 times the stock solution), the injection force is small and sufficient injection is difficult and cracking properties are inferior, while the propellant is more than this ratio ( This is because the stock solution and the propellant may be separated.

  In addition, it is needless to say that a fragrance, a colorant, a preservative, etc. may be optionally added to the stock solution as necessary.

(Example)
As shown in Table 1, a stock solution containing ethoxydiglycol as a solvent, surfactants (PEN-4630 and HCO-20 manufactured by Nikkor Co.), hydroxyethyl cellulose as a thickener, and the balance being water was prepared. . This stock solution and a propellant (LPG) were blended at a predetermined ratio to prepare an aerosol composition and filled in a container.
Table 1 shows the results of evaluating the propellant formed by spraying on the hand with respect to cracking property, feeling of use, and the presence or absence of a change from the sherbet state to the cracking foam state, and it was confirmed that all were satisfactory. In particular, immediately after jetting, the jet is in a sherbet state and feels like a cold solid, and after a few seconds, it changes to a viscous liquid, gradually foaming occurs in this liquid, and the foam formed by the foaming is crackling. The process of becoming a cracking foam state that makes a sound and breaks bubbles has provided a completely new form of foam-like cosmetics that has never existed before.

(Comparative example)
The same components as those in Examples were blended, and the content of ethoxydiglycol was 5% by mass (Comparative Example 1), the content of ethoxydiglycol was 40% by mass (Comparative Example 2), stock solution: propellant An aerosol composition was prepared for a compounding ratio of 1: 0.3 (comparative example 3) in a mass ratio (comparative example 3) and a mixture ratio of stock solution: propellant in a mass ratio of 1: 4 (comparative example 4). The container was filled.
Table 2 shows the results of evaluating the propellant formed by spraying on the hand, cracking performance, feeling of use, and the presence or absence of a change from a sherbet state to a cracking foam state, but none of the comparative examples can be satisfied. It could be confirmed.
