Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to an aerosol hair cosmetic, and more particularly to an excellent aerosol hair cosmetic that allows a hair styling agent to directly reach the hair styling area. [Prior Art] Conventionally, hair cosmetics such as hair liquids, hair mousses, hair sprays, and setting lotions include:
Polyvinylpyrrolidone, polyvinylpyrrolidone-
Film-forming polymers such as vinyl acetate copolymer, vinyl acetate-crotonic acid copolymer, polyvinyl methyl ether-maleic acid half ester copolymer, carboxylated vinyl acetate copolymer, acrylic resin (anionic, amphoteric), etc. Alternatively, a hair styling ingredient such as an oil such as a polyoxyalkylene derivative or its phosphoric acid ester dissolved in a solvent such as water or ethanol, or an aerosol prepared by adding a propellant to the hair are used. The hair is fixed by forming a film of the resin on the hair. [Problems to be Solved by the Invention] These hair cosmetics are used by applying them onto the hair, or by spraying or directly sprinkling them on the hair surface, but in both cases, the hair styling ingredients are removed from the tips of the hair. Because it spreads, it has drawbacks such as difficulty in setting and poor feel. Especially when setting curly hair,
It is necessary to take complicated steps such as wetting the hair once and then styling it with a hair dryer, so there has been a desire to develop hair cosmetics with good setting properties that allow hair styling ingredients to easily reach the hair styling area directly. . [Means for Solving the Problems] In view of the above-mentioned circumstances, the present inventors conducted intensive research to develop a hair cosmetic that solved the above-mentioned problems.
The present invention was completed by discovering that excellent hair styling properties can be obtained by spraying the product in a trickle and applying it to the hair. That is, the present invention provides a mixture of a hair cosmetic composition containing a hair styling agent and a propellant, in which the diameter of the outlet of the spray button is 0.3 to 1.5 mm, and the spray button is sprayed from the center line of the stem fitting part of the button to the tip of the nozzle. distance to 10
The present invention provides an aerosol hair cosmetic that is filled into an aerosol container having a nozzle of mm or more. The hair styling agent to be incorporated into the hair cosmetic composition containing the hair styling agent used in the present invention includes crosslinked polymer fine particles, oils and fats, or non-film-forming substances such as polyoxyalkylene derivatives or phosphoric esters thereof; Any of a variety of film-forming materials can be used. Among non-film-forming substances, crosslinked polymer fine particles are produced by copolymerizing a monofunctional oil-soluble monomer and a polyfunctional oil-soluble monomer by a known method such as suspension polymerization, dispersion polymerization, emulsion polymerization, etc. Crosslinking may be formed by copolymerizing a monofunctional oil-soluble monomer with a suitable polyfunctional oil-soluble monomer, or by forming a homopolymer and then post-crosslinking by an appropriate method, or by self-crosslinking. Monomers and reaction conditions may be selected accordingly. As the polyfunctional oil-soluble monomer, one having a plurality of ethylenically unsaturated bonds is preferably used. The monofunctional oil-soluble monomer having only one ethylenically unsaturated bond is preferably one having a polymer glass transition temperature of 300°K or less, such as ethyl acrylate, propyl acrylate, n-butyl acrylate, Acrylic esters such as tert-butyl acrylate, sec-butyl acrylate, n-hexyl acrylate, cyclohexyl acrylate, n-octyl acrylate, 2-ethylhexyl acrylate, n-lauryl acrylate; n-butyl methacrylate , methacrylic acid esters such as n-hexyl methacrylate, n-octyl methacrylate, 2-ethylhexyl methacrylate, and n-lauryl methacrylate; vinyl ethers such as methyl vinyl ether and ethyl vinyl ether, and vinyl esters. Furthermore, examples of the polyfunctional oil-soluble monomer having a plurality of ethylenically unsaturated bonds include divinylbenzene, ethylene glycol diacrylate, ethylene glycol dimethacrylate, trimethylolpropane acrylate, and the like. Oils and fats include glycerides such as castor oil, cacao oil, mink oil, avocado oil, and olive oil; waxes such as beeswax, spermaceti, lanolin, and carnauba wax; cetyl alcohol, oleyl alcohol, hexadecyl alcohol, lauryl alcohol, and stearyl alcohol. , isostearyl alcohol, 2-octyldodecanol, propylene glycol, polypropylene glycol,
Alcohols such as glycerin; isopropyl myristate, hexyl laurate, cetyl lactate,
Esters such as propylene glycol monostearate, oleyl oleate, hexadecyl 2-ethylhexanoate, octyldodecyl myristate; dimethylpolysiloxane, methylphenylpolysiloxane, polyether-modified silicone oil, epoxy-modified silicone oil, amino-modified silicone Examples include silicone derivatives such as oil and alkyl-modified silicone oil. Examples of polyoxyalkylene derivatives include the following general formula: [In the formula, R ₁ and R ₂ are the same or different and represent a hydrogen atom or an alkyl group having 1 to 18 carbon atoms, and n is 20 to 18]
An integer of 50, m is an integer of 0 to 5] Compounds represented by or general formula [In the formula, R ₃ is an alkyl group having 4 to 18 carbon atoms, R ₄
is a hydroxyl group,

[Action and effect of the invention]

Since the aerosol hair cosmetic composition of the present invention can directly deliver the hair cosmetic composition containing a hair styling agent in liquid form to the hair styling area, it is possible to quickly style the hair even when the hair has strong curls such as sleeping curls. , the stability and durability of the hairstyle are good. [Example] Next, the present invention will be explained in detail with reference to Examples. Example 1 A mousse type hair styling composition having the composition shown below was produced. (Composition) Polymer fine particles 5.0 (wt%) (2-ethylhexyl acrylate polymer) Cetyltrimethylammonium chloride 0.75 Cetostearyl alcohol 1.0 Glyceryl monostearate 0.5 Fragrance Appropriate amount of water Balance total 100 The obtained composition (viscosity 3 cps) The mixture was mixed with the propellant shown in Table 1 and filled into an aerosol container having a nozzle with a length of 20 mm and a nozzle diameter of 0.5 mm to produce an aerosol hair cosmetic. The filling ratio is composition/propellant = 90/10.

[Table] When Cosmetic A (internal pressure 1.5Kg・G/cm ² ) is sprayed, the composition does not reach the root of the hair, so
I had trouble getting my hair styled. Cosmetics C (internal pressure 10
Kg·G/cm ² ), the composition was scattered around and did not reach the target site efficiently. When Cosmetic B (internal pressure 5 kg/cm ² ) is sprayed, the sprayed liquid becomes a trickle and foams near the root of the target hair, allowing hair to be styled from the root to the tip of the hair well, and with a pleasant feel. It was good and warm. Example 2 The composition shown in Example 1 (viscosity 3 cps) was
It was filled with LPG into an aerosol container having a nozzle shown in Table 2 to produce an aerosol hair cosmetic. The filling ratio (weight) is composition/propellant=
90/10, and the internal pressure (gauge pressure) at 35℃ is
It was 4.0Kg・G/ ^cm2 .

[Table] When Cosmetic D is sprayed, the composition scatters over a wide angle and does not reach the root of the hair, making it impossible to style the hair adequately. Cosmetic E has a nozzle diameter that is too small.
If used continuously, it will cause clogging, which is not preferable. When Cosmetic F is sprayed, too much of the composition comes out, causing a deterioration in the feel of the hair, such as stiffness and stickiness. In Cosmetics G and H, the liquid was sprayed in a trickle, foamed near the root of the target hair, and the hair could be styled well from the root to the tip, and had a good feel. Comparative Example 1 A mousse type hair styling composition having the composition shown below was prepared. (Composition) Polymer fine particles 2.0 (wt%) (Lauryl acrylate polymer) Distearyldimethylammonium chloride

Moreover, the composition did not reach the vicinity of the hair roots. Example 3 The composition and propellant shown below were used to fill an aerosol container with a nozzle with a length of 20 mm and a nozzle diameter of 0.3 mm at a ratio of composition/propellant = 3:7 (internal pressure of 4 kg.
